| 23 | Marty Whitman Third Avenue Management |
7.60 | FOLLOW | 9 | 7 | 9 | 8 | 7 | 9 | 7 | 1 | One of the most intellectually rigorous value investors in history; his 'safe AND cheap' framework, balance-sheet primacy, and credit-analysis approach to equities are deeply aligned with our floor-price methodology — study his letters and books, not current Third Avenue holdings. |

Charles Thomas Munger (1924-2023) was Warren Buffett's partner, vice chairman of Berkshire Hathaway, and chairman of Daily Journal Corporation. A lawyer by training (Harvard Law, no undergraduate degree), Munger practiced law in Los Angeles before transitioning to full-time investing. He ran a private investment partnership from 1962 to 1975 that achieved approximately 19.8% annual returns versus 5.2% for the Dow — extraordinary outperformance. He is widely credited with transforming Buffett's investing approach from pure Graham-style 'cigar butt' value investing to buying wonderful businesses at fair prices. Munger was known for his extraordinary breadth of knowledge, his emphasis on multidisciplinary thinking ('mental models' from multiple fields), his blunt honesty, and his wit. He pass...
Munger's philosophy evolved significantly from Graham-style deep value toward quality-focused investing. His core principles: (1) 'Invert, always invert' — avoid stupidity rather than seeking brilliance; focus on what can go wrong; (2) Circle of Competence — only invest in what you truly understand, and be honest about the boundaries; (3) Mental Models — use frameworks from multiple disciplines (psychology, physics, biology, mathematics, engineering) to analyze investments and avoid cognitive biases; (4) Wonderful businesses at fair prices — Munger convinced Buffett that it's 'far better to buy a wonderful company at a fair price than a fair company at a wonderful price'; (5) Moats and durability — focus on businesses with sustainable competitive advantages that can compound for decades; (...
Extremely concentrated. At Berkshire, Munger and Buffett routinely held 60-80% of the equity portfolio in 5-6 positions. The Daily Journal portfolio (which Munger managed directly) was even more concentrated — at its peak it held essentially 4 stocks: Bank of America, Wells Fargo, US Bancorp, and POSCO, with BYD Company added later. Munger's personal partnership (1962-1975) was similarly concentrated, sometimes with 30-40% in a single position. He explicitly advocated for concentration, arguing that the third-best idea shouldn't get the same capital as the best idea. His holding periods were extremely long — BYD was held from 2008 until his death, Costco for decades, Berkshire for 45+ years.
Munger's track record is among the best in investment history. His partnership (Wheeler, Munger & Co., 1962-1975) returned 19.8% annually vs. 5.2% for the Dow Jones — nearly 4x the market return over 13 years, though with significant volatility (down 31.9% in 1973-74). At Berkshire Hathaway (1978-2023), as Buffett's intellectual partner, he helped compound book value at approximately 20% annually for 45 years, turning Berkshire into one of the most valuable companies in the world. At Daily Journal, his stock portfolio grew from roughly $30M to over $300M. His BYD investment (2008) returned approximately 30x. His influence on Buffett's evolution — the See's Candies purchase, the Coca-Cola investment, the Apple position — arguably generated hundreds of billions in value.
Munger was remarkably transparent about his thinking process, investment philosophy, and mental models. He gave extensive annual speeches at Berkshire and Daily Journal shareholder meetings, participated in the DJCO annual meeting Q&A for decades, and his speeches and writings have been compiled into 'Poor Charlie's Almanack.' He was brutally honest about mistakes (Dexter Shoe, airline investments, etc.). Daily Journal filed 13F reports disclosing holdings. However, Munger's personal portfolio was private, and his specific role in individual Berkshire investment decisions (vs. Buffett's) was often unclear. His transparency was more philosophical than positional — you could learn exactly how he thought, but not always what he specifically owned beyond public filings.
Munger's integrity was legendary and virtually unquestioned. He was blunt to the point of rudeness, never sugar-coated bad news, and was willing to publicly disagree with conventional wisdom, popular opinion, and even his own partner when necessary. He lived modestly relative to his wealth, drove an old car, and lived in the same house for decades. He was a major philanthropist (Munger donated hundreds of millions to educational institutions). He was scathingly critical of fee-extracting financial intermediaries, excessive executive compensation, and accounting fraud. His moral framework was deeply considered — he frequently referenced ethical philosophy and emphasized the importance of deserving what you want. He was one of the most intellectually honest public figures in finance.
BYD Company — invested $230M in 2008 for 10% stake, grew to over $7B+ (one of the greatest international investments ever made by an American investor). Costco — board member for decades, held as a core personal and Berkshire holding. Berkshire Hathaway — his life's work alongside Buffett. Daily Journal Corporation — built from a small newspaper into a technology/software company. Through Berkshire: See's Candies, Coca-Cola, Apple, American Express, Bank of America, GEICO — all bearing Munger's intellectual fingerprints in the analysis and purchase decisions. Wells Fargo was a major position that eventually became a notable mistake due to the fake accounts scandal.
Munger is arguably the single most relevant historical investor to our approach. The alignment is near-perfect: (1) Extreme concentration — 'very few investments' is our direct inheritance from Munger; (2) Long-term holding — decades-long holding periods match our 5-10+ year horizon; (3) Wonderful businesses at fair prices — this IS our approach; (4) Downside-first thinking — 'Invert, always invert' maps directly to our 'little chance of losing money' philosophy; (5) Mental models and multidisciplinary thinking — our 9-area analysis framework is inspired by Munger's approach; (6) No leverage, no shorting — identical to our constraints; (7) Intellectual honesty — our emphasis on bias awareness comes directly from Munger's teachings on cognitive biases. The only gap is AGI awareness, though ...
Born 1930 in Omaha, Nebraska. Studied under Benjamin Graham at Columbia Business School. Founded Buffett Partnership in 1956, compounding at ~29% annually until 1969 dissolution. Took control of Berkshire Hathaway (originally a textile mill) in 1965, transforming it into a $1T+ conglomerate. The most successful investor in history by most measures. Chairman and CEO of Berkshire Hathaway for 60 years. As of his 2025 annual letter, announced Greg Abel would take over as CEO by year-end 2025, marking the end of an era. Net worth approximately $150B. His annual letters to shareholders are considered essential reading for any serious investor.
Evolved over decades from Graham-style deep value (cigar butts, net-nets) to Munger-influenced quality compounding (wonderful businesses at fair prices). Core principles: (1) Circle of competence -- only invest in what you understand, (2) Margin of safety -- buy well below intrinsic value, (3) Durable competitive advantages (moats), (4) Think like a business owner, not a stock trader, (5) Be fearful when others are greedy and greedy when others are fearful, (6) Long-term orientation -- 'Our favorite holding period is forever,' (7) Management matters -- honest and competent managers, (8) Float-based leverage through insurance operations. In later years, increasingly focused on very large cap quality businesses due to the constraints of Berkshire's enormous size ($300B+ equity portfolio, $30...
Extremely concentrated at the top despite large portfolio. Apple alone has comprised 40-50% of the equity portfolio (reduced significantly in 2024-2025 via sales). Top 5 positions typically represent 70-80% of equity holdings. However, Berkshire's true portfolio includes wholly-owned subsidiaries (BNSF railroad, Geico, See's Candies, Dairy Queen, etc.) worth hundreds of billions. Cash/Treasury position grew to approximately $330B by end of 2025 -- the largest cash hoard in corporate history, suggesting Buffett sees few attractive opportunities. Recent activity: sold majority of Apple position, sold entire Paramount position, built large positions in Japanese trading houses (Itochu, Marubeni, Mitsubishi, Mitsui, Sumitomo) and Occidental Petroleum.
The greatest documented track record in investment history. Berkshire book value compounded at ~20% annually from 1965-2024 (~60 years). Partnership returns were ~29% annually from 1957-1969. Market cap grew from ~$18/share in 1965 to ~$700,000+/share by 2025. Has outperformed the S&P 500 in the majority of decades. Performance has naturally slowed in recent decades due to Berkshire's enormous size (law of large numbers), but still impressive. Recent years show strong operating earnings growth from wholly-owned businesses even as equity portfolio returns have moderated.
Very high for someone of his stature. Annual shareholder letters are detailed, honest, and self-critical (admits mistakes publicly). Annual meeting (the 'Woodstock for Capitalists') provides hours of Q&A. 13F filings are closely watched. Regular media appearances (CNBC, etc.) though has reduced these. However, individual attribution of Berkshire's stock picks (Buffett vs Combs vs Weschler) has become harder in recent years. The 2025 annual letter was notably candid about succession and legacy.
Highest possible. Has maintained a consistent ethical standard for 60+ years. Pledged to give away 99%+ of his wealth (primarily to Gates Foundation, now transitioning to family-run charitable trust). Has been consistently honest about mistakes (Dexter Shoes, textile mills, Kraft Heinz). Never engaged in accounting manipulation or shareholder-unfriendly behavior. His compensation has been $100K/year for decades. The ultimate reference case for investor integrity.
Apple (reduced but still largest), Bank of America, American Express, Coca-Cola, Chevron, Occidental Petroleum, Japanese trading houses (5 major sogo shosha), Kraft Heinz, Moody's, DaVita, Citigroup, T-Mobile. Wholly-owned: BNSF Railroad, GEICO, Berkshire Hathaway Energy, Precision Castparts, See's Candies, Dairy Queen, and dozens more. ~$330B in cash/treasuries.
Essential reference but limited for direct idea generation. Buffett's philosophy IS our philosophy's foundation. His principles of margin of safety, circle of competence, and long-term orientation are embedded in our approach. However, his current portfolio is constrained by Berkshire's enormous size -- he can only buy mega-caps and full companies, which limits the overlap with our opportunity set. The massive cash position is itself an important signal (Buffett sees markets as overvalued). The Japanese trading house investments and Occidental position show he still makes bold moves. As a reference for philosophy and temperament, irreplaceable. As a source of actionable ideas for a smaller portfolio, limited.
Nick Sleep is a retired British investor who, together with his partner Qais Zakaria, ran the Nomad Investment Partnership from 2001 to 2013/2014. Before founding Nomad, Sleep worked at Marathon Asset Management in London, where he developed his analytical framework. Nomad was structured as a long-only, concentrated partnership (similar to Buffett's early partnerships) with a tiny AUM that grew modestly over time -- they deliberately kept the fund small (never exceeding approximately $2-3 billion) to preserve their ability to compound capital efficiently. After winding down Nomad in 2013-2014, Sleep and Zakaria returned all capital to investors and retired from professional money management. They now manage their own personal capital through their family office and are involved in philanth...
Sleep's philosophy is among the most original and deeply thought-through in the investment world. His key concepts include: (1) 'Destination Analysis' -- rather than forecasting next quarter's earnings, Sleep asks 'what will this business look like in 10-20 years?' and works backward from the destination to assess whether the current price makes sense. He thinks about where a business is going, not where it has been. This is a genuinely long-term framework that few investors actually practice. (2) 'Scale Economics Shared' -- his most important original concept. Some businesses achieve economies of scale and choose to share those savings with customers through lower prices, which drives volume growth, which creates more scale advantages, which enables further price reductions, in a virtuous...
Extraordinarily concentrated -- the most concentrated portfolio among established fund managers. At its peak, Nomad held roughly 3-5 core positions representing 80-90% of the portfolio, with 10-15 total positions. The three dominant positions for the latter years of the partnership were Amazon (approximately 25-30%+), Costco (approximately 25-30%+), and Berkshire Hathaway (approximately 15-20%+). Other positions included Southwest Airlines, Stagecoach Group, and various 'scale economics shared' businesses. Portfolio turnover was minimal -- Sleep bought positions with the intention of holding them for 10-20+ years. Entirely long-only, no leverage, no shorting, no derivatives. The partnership had a simple fee structure (1% management fee, 20% performance fee above a 6% hurdle) with a high-wa...
Exceptional. Nomad Investment Partnership (2001-2013/2014) generated approximately 921% cumulative return over 13 years, equivalent to approximately 18-20% annualized, compared to approximately 116% cumulative (6.5% annualized) for the MSCI World Index over the same period. This represents roughly 12-14% annualized outperformance over the global equity benchmark -- one of the best long-term track records in hedge fund history. Critically, these returns were achieved with a simple, long-only, concentrated strategy (no leverage, no shorting, no derivatives), making the risk-adjusted performance even more remarkable. The returns were front-loaded toward the later years as Amazon and Costco compounded dramatically. Sleep's single best decision -- buying Amazon aggressively when it was trading ...
Moderate during fund operation, high post-retirement. During Nomad's active years, Sleep wrote detailed semi-annual letters to partners (not publicly available at the time) explaining his investment philosophy, discussing positions, and sharing his thinking on competitive dynamics and business quality. These letters are intellectually rich, philosophically profound, and refreshingly honest about uncertainty and mistakes. After winding down the fund, the letters were made publicly available (through the IGY Foundation website and widely circulated online), making them one of the most transparent records of investment thinking ever published. However, Sleep gives virtually no interviews, does not maintain a public presence, and does not comment on markets or individual companies. His post-re...
Exceptional -- among the highest integrity investors in the public record. Sleep and Zakaria voluntarily returned all investor capital and closed the fund while performance was excellent and AUM was growing, sacrificing millions in ongoing management and performance fees. This is nearly unprecedented in the hedge fund industry, where most managers cling to AUM for as long as possible. They closed because they believed the fund had grown large enough to impair future returns and felt it was the right thing to do for investors. Sleep invested substantially alongside partners and never prioritized fee income over performance. His letters are devoid of self-promotion, marketing language, or spin -- they read like genuine intellectual explorations rather than sales documents. He has never been ...
The definitive Nomad positions were: Amazon.com (largest position for latter years, bought in early 2000s at approximately $30-40/share and held through all volatility to $300+ at fund close -- the position would be worth many billions today), Costco Wholesale (second-largest position, the archetypal 'scale economics shared' business), and Berkshire Hathaway (third-largest position, as an example of rational capital allocation and business quality). Earlier positions included Stagecoach Group, Southwest Airlines (another scale economics shared example), and various other businesses that shared scale advantages with customers. The portfolio evolved from more diversified in the early years to hyper-concentrated in the final years as Sleep gained conviction in his best ideas.
Nick Sleep is perhaps the single most intellectually relevant investor to our approach. His 'destination analysis' framework -- asking where a business will be in 10-20 years -- is perfectly aligned with our AGI-focused long-term analysis. His 'scale economics shared' concept provides a powerful framework for analyzing tech platform businesses (including Meta, Google, Amazon) that share their scale advantages with users. His extreme concentration (3-5 positions) matches our ideal of very few, high-conviction positions. His long-only, no-leverage, infinite time horizon approach matches ours exactly. His emphasis on business quality as the margin of safety aligns with our floor price philosophy. His letters are essential reading -- arguably the single best collection of investment writing fo...
Born 1966 in China. Survived the Tiananmen Square protests in 1989 and fled to the US. Earned three degrees from Columbia University (economics, law, MBA). Founded Himalaya Capital in 1997. Charlie Munger's only external money manager -- Munger entrusted a significant portion of his family's wealth to Li Lu, calling him a 'Chinese Warren Buffett.' Manages roughly $3-6B in AUM. Known for extreme patience and concentration. His early investment in BYD (at Munger's suggestion, or vice versa -- the two influenced each other) was one of the great value investments of the 2000s. Deeply intellectual, has written and spoken about the intersection of civilization, knowledge, and investing.
Deep value with a long-term orientation. Believes in understanding businesses at a fundamental level, buying with a large margin of safety, and holding for years or decades. Strongly influenced by Munger's multi-disciplinary mental models approach. Favors businesses with durable competitive advantages. Willing to hold concentrated positions and sit in cash when nothing meets his criteria. Has emphasized that the best investments come from understanding a business so well that price fluctuations become irrelevant. Views investing as a search for knowledge and truth about businesses.
Extremely concentrated. Historically holds 5-10 positions with top 3 comprising 60-80% of the portfolio. US 13F filings show heavy positions in Micron Technology, Bank of America, Apple, and Alphabet in recent years. Also holds significant non-US positions (BYD, other Asian equities) not visible in 13F. Patient holder -- positions often held for 5+ years. Willing to make large bets when conviction is high. Has held significant cash positions when opportunities are scarce.
Exceptional long-term returns, estimated at 20-30% annualized over 25+ years, though exact figures are private. The BYD investment (entered ~2003 at very low prices) returned 50x+. Munger's willingness to give him sole external management authority is itself a strong endorsement. Has compounded through multiple cycles without blowing up. One of the best long-term track records among value-oriented managers globally, though limited public disclosure makes precise measurement difficult.
Low public transparency. Does not do interviews frequently. No public letters to investors. 13F filings are available but only show US long equity positions. Does not seek media attention. Has given occasional talks at Columbia and other venues, but is generally private. His investment thinking can be gleaned from a few speeches and his book 'Civilizations, Modernization, Value Investing and China' (published in Chinese).
Very high. Munger's endorsement is the ultimate character reference in value investing circles. Li Lu has maintained a consistent, principled approach for decades. No scandals, no style drift for marketing purposes, no questionable behavior. His personal history (surviving Tiananmen, building a career from nothing in the US) speaks to extraordinary character and resilience. Known for intellectual honesty and willingness to admit mistakes.
Micron Technology (large position), Bank of America, Apple, Alphabet/Google, BYD (non-US, long-standing position from early 2000s). Has historically held positions in Berkshire Hathaway. Portfolio tends to favor large-cap quality businesses with cyclical entry points.
Extremely high. Li Lu is perhaps the closest living investor to our philosophy: concentrated, long-term, downside-first, deeply analytical, patient. He buys when there is very little chance of permanent loss. His willingness to hold cash and wait, combined with decisive action on high-conviction ideas, mirrors our approach perfectly. Pre-approved by us for good reason. His Micron position is interesting -- a cyclical semiconductor play with tangible assets and potential AGI tailwinds (memory demand). Worth tracking every 13F filing.
Born 1964 in Mumbai, India. Moved to the US for education. Electrical engineering degree from Clemson, worked at Tellabs. Founded TransTech Inc. (IT consulting/systems integration) in 1991, grew it to $30M revenue, then sold it. Founded Pabrai Investment Funds in 1999, modeled after the Buffett Partnership structure (no management fee, 6% hurdle, 25% above hurdle). Author of 'The Dhandho Investor' and 'Mosaic: Perspectives on Investing.' Won charity lunch auction with Buffett in 2007 for $650,100. Also founded Dakshana Foundation (education for underprivileged Indian students). Self-described 'shameless cloner' -- openly copies ideas from great investors.
Deeply Buffett/Munger influenced. Core principles: (1) Few bets, big bets, infrequent bets, (2) Heads I win, tails I don't lose much (asymmetric risk/reward), (3) Shameless cloning -- copies ideas from investors he respects, (4) Checklist-based investing to avoid mistakes, (5) Simple, understandable businesses with durable moats, (6) Low downside with significant upside. Has evolved from pure deep value (cigar butts) to more quality-oriented over time. Focuses on situations where the odds are heavily in his favor. Extremely patient -- willing to do nothing for long periods.
Very concentrated. Typically holds 5-10 positions with top 3-5 comprising 70-90% of portfolio. Has gone through distinct phases: early years focused on US small/mid cap value, then shifted to international (Turkey, India, Korea, coal/shipping companies), and more recently moved toward tech/semiconductor names. Recent 13F filings show heavy concentration in Micron Technology, with positions also in Alphabet, Amazon, and others. Known for making large bets on out-of-favor cyclical businesses. Fee structure (no management fee) is highly aligned with investors.
Strong long-term with significant volatility. From 1999 to approximately 2018, Pabrai Funds compounded at roughly 12-15% annualized net of fees (vs ~7-8% for S&P 500 over same period). However, had some painful drawdowns -- lost ~65% in 2008 GFC (recovered fully by 2013-2014). His Turkey investments (circa 2017-2019) were a mixed bag. Coal and shipping bets were contrarian and had mixed results. The Micron position has been a strong performer. Overall, a solid compounder who has beaten the market over 25+ years but with higher volatility than peers. His fee structure means investor returns track closely to gross returns.
High. Gives annual meeting presentations (available on YouTube). Has written two popular investing books. Speaks frequently at conferences and universities. 13F filings are straightforward to track. His 'shameless cloning' philosophy means he openly discusses where he gets ideas. Very accessible for a fund manager of his stature. Probably the most transparent investor in this group.
Very high. The Buffett Partnership fee structure (no management fee, high hurdle) is the gold standard for alignment. Dakshana Foundation philanthropy demonstrates genuine character. Has been consistently honest about mistakes (publicly discussed his 2008 losses, Turkey investment struggles). No scandals or ethical concerns. Well-regarded in the value investing community.
Micron Technology (very large position, 30-50%+ of portfolio at times), Alphabet/Google, Amazon, previously held positions in Fiat Chrysler, coal companies, Turkish equities, Seritage Growth Properties. Portfolio has shifted significantly toward tech/semiconductor in recent years.
Very high. Pabrai's philosophy -- few bets, big bets, heads I win tails I don't lose much -- is almost identical to our floor price approach. His concentration, long-term orientation, and asymmetric thinking are closely aligned. His Micron position is particularly relevant given AGI/AI memory demand thesis. His transparency makes him easy to follow. His willingness to go contrarian (coal, Turkey, shipping) mirrors our willingness to look at unloved areas. Fee structure proves alignment. The 'shameless cloner' approach is pragmatic and honest. Main concern: higher volatility than some peers suggests position sizing or timing is occasionally off.
Cliff Sosin is the founder and managing member of CAS Investment Partners, a New York-based investment partnership. Before founding CAS in 2012, he worked at Fir Tree Partners (a multi-billion dollar hedge fund) and before that at Cerberus Capital Management. He graduated from the University of Pennsylvania (Wharton). CAS Investment Partners is structured as a long-biased, concentrated hedge fund focused on a very small number of high-conviction positions. Sosin is known in the value investing community for his extreme concentration, deep fundamental research, and willingness to take very large positions in companies he understands thoroughly. He is relatively low-profile and rarely gives public interviews, preferring to let his results speak for themselves.
Sosin's philosophy is one of extreme concentration and deep understanding. Key tenets: (1) Ultra-concentrated portfolio — he often holds only 3-5 positions, with a single stock sometimes representing 40-60% of the portfolio. (2) Deep, proprietary research — he spends months understanding a business before investing and develops a level of understanding that rivals insiders. (3) Long-term holding — he holds positions for years and rarely trades. (4) Focus on businesses with durable competitive advantages, strong network effects, and high returns on incremental capital. (5) He thinks about businesses as compounders — looking for companies where the intrinsic value per share grows at attractive rates over long periods. (6) Contrarian willingness — he is willing to hold positions through signi...
Extremely concentrated — among the most concentrated hedge funds in the industry. Based on 13F filings, CAS Investment Partners has historically held massive positions in Amazon (often 30-50%+ of portfolio) and Meta/Facebook (often 20-40% of portfolio). At various times, the portfolio has been essentially a 2-3 stock portfolio. He runs a long-biased strategy with minimal hedging. AUM is estimated in the $200-500M range. The extreme concentration means the fund's returns are highly correlated with the performance of a very small number of positions. He favors large-cap technology platforms with strong network effects and massive scale advantages.
CAS Investment Partners has generated exceptional long-term returns, significantly outperforming the S&P 500 since inception in 2012. The fund has benefited enormously from its massive concentrated positions in Amazon and Meta, which have been among the best-performing stocks over the past decade. Performance has been volatile due to concentration — the fund likely drew down significantly during Meta's 2022 decline and Amazon's pullback — but the long-term compounding has been outstanding. His willingness to hold Meta through the 2022 drawdown (when it fell ~75%) and ride the recovery demonstrates extraordinary conviction and a strong process. Estimated compound returns since inception are well above market returns, though exact figures are private.
Low to moderate transparency. Sosin is quite private and rarely gives public interviews or presentations. His investor letters are not publicly available. His 13F filings provide the primary public window into his positioning, and these reveal an extraordinarily concentrated portfolio. He does not maintain a blog, podcast, or social media presence. The few interviews he has given reveal a thoughtful, deeply analytical investor. His low profile is both a feature (he focuses on investing, not marketing) and a limitation (less opportunity to learn from his thinking publicly).
Very high integrity based on available evidence. He has significant personal capital invested in the fund alongside clients, ensuring strong alignment of interests. His extreme concentration demonstrates conviction rather than asset-gathering behavior — a fee-focused manager would never concentrate this heavily. He does not engage in self-promotion or marketing. His background at reputable firms (Fir Tree Partners, Cerberus Capital Management) and his Wharton education suggest strong professional credentials. He appears to be a genuine investor, not a fee-extractor.
Based on 13F filings: Amazon (historically 30-50%+ of portfolio — his largest and most enduring position), Meta/Facebook (historically 20-40% of portfolio — held through the 2022 drawdown), and a small number of other positions that rotate. The portfolio is overwhelmingly dominated by Amazon and Meta, reflecting his conviction in large-scale technology platforms with network effects. At times, these two positions alone have represented 70-90% of his reported holdings.
Very high relevance. Sosin's approach is perhaps the closest match to our philosophy among this group: extreme concentration, long-term holding, focus on durable competitive advantages, no leverage/shorting in practice (long-biased), and willingness to hold through drawdowns. His portfolio overlap with our own analysis (Meta is our first deep-dive company) is notable. His Amazon/Meta concentration suggests he has reached similar conclusions about the durability and value of large-scale technology platforms. The main gaps: (1) his low transparency means we learn less from him than from more public investors, (2) he does not appear to publicly discuss AGI or transformative AI, though his portfolio positioning in Amazon and Meta implicitly benefits from AI tailwinds.
Chuck Akre is the founder and chairman of Akre Capital Management, based in Middleburg, Virginia. Founded in 1989, the firm manages approximately $9 billion in assets (as of February 2026) across an ETF (Akre Focus ETF), private partnerships, and separately managed accounts. Akre began his investment career in the 1970s at a regional brokerage firm (Johnston, Lemon & Co.) in Washington, D.C., where he ran a small fund. He later managed the FBR Focus Fund (1997-2009), compiling one of the best mutual fund records of his era -- approximately 12-13% annualized over 12 years, significantly outperforming the S&P 500. In 2009 he left FBR to start his own firm and launched the Akre Focus Fund (ticker AKREX), which continued his exceptional track record. He is widely regarded as one of the finest ...
Akre's philosophy is built around one central concept: finding 'compounding machines.' He seeks businesses that can compound intrinsic value at high rates for extended periods with minimal risk of permanent capital loss. His analytical framework is the 'three-legged stool,' requiring all three legs to be present: (1) Extraordinary Business -- high returns on equity/capital, pricing power, asset-light models, strong competitive position, growing addressable market. He wants businesses that can reinvest at 15-20%+ ROE for decades. (2) Extraordinary Management -- honest, talented operators who think like owners. He looks for insider ownership, rational capital allocation, candor, and long tenure. He is allergic to self-dealing, excessive compensation, or empire-building. (3) Extraordinary Rei...
Extremely concentrated. The Akre Focus Fund/ETF typically holds 20-25 positions, with the top 10 representing approximately 60-70% of portfolio value. Some positions have been held for 10-20 years. Portfolio turnover is among the lowest in the fund industry -- typically 5-15% annually. Sector exposure tilts toward capital-light businesses with high returns on equity: financial exchanges, payment networks, tower companies, auto parts retail, insurance, and technology. He avoids capital-intensive businesses, commodity producers, utilities, and heavily regulated industries. Long-only, no leverage, no derivatives, no shorting. The portfolio reads like a carefully curated list of American compounding machines. He is global in theory but US-dominated in practice. Average position size for top ho...
Outstanding long-term track record, among the best in the mutual fund industry. At FBR Focus Fund (1997-2009): approximately 12-13% annualized, outperforming S&P 500 by 3-5% annually over 12 years. Akre Focus Fund (AKREX, 2009-present): approximately 14-16% annualized since inception through 2024, significantly outperforming the S&P 500 over most multi-year periods. The fund's risk-adjusted returns are exceptional -- outperformance has been achieved with lower-than-market volatility, lower drawdowns, and lower beta, demonstrating true alpha generation rather than leveraged beta. Over the 2009-2024 period, $10,000 invested in AKREX grew to approximately $80,000-90,000, roughly doubling the S&P 500's growth. The strategy suffered in 2022 (down more than the market, as high-quality growth sto...
High transparency. As a registered investment company, the fund files quarterly holdings reports and publishes semi-annual and annual reports. Akre Capital publishes thoughtful annual letters that explain their investment philosophy, discuss individual positions, share insights on compounding, and acknowledge mistakes. These letters are well-regarded in the investment community for their clarity and intellectual honesty. The firm's website provides educational content about their approach, including essays on compounding, the three-legged stool, and 'bottleneck businesses.' Akre and his team (John Neff, Chris Cerrone) participate in interviews and conferences, sharing their thinking openly. Fee structure is straightforward and disclosed: the Akre Focus ETF has an expense ratio of approxima...
Very high integrity. Akre has spent 35+ years as a practitioner with a spotless record -- no ethical scandals, no regulatory issues, no conflicts of interest. He is known for his genuine humility, intellectual honesty, and willingness to admit mistakes. He has kept AUM manageable (capping at ~$12-15B at peak before naturally declining with the transition) to preserve performance rather than maximizing fees -- a strong signal of investor alignment. He and his team invest heavily in their own fund. His succession planning was thoughtful and transparent -- he groomed successors (John Neff and Chris Cerrone) over many years rather than abruptly departing. He is known in the community as a man of high character, consistent philosophy, and genuine passion for the craft of investing. He has never...
Top holdings have historically included and/or currently include: Mastercard (long-held core position, ~8-10% weight), American Tower (tower REIT with reinvestment runway, ~7-9%), O'Reilly Automotive (auto parts retailer with exceptional ROIC and buyback program, ~7-9%), Moody's Corporation (ratings duopoly with Buffett-like economics, ~6-8%), Visa (payment network, ~5-7%), CoStar Group (commercial real estate data monopoly, ~5-7%), Constellation Software (serial acquirer of vertical market software companies, ~4-6%), Roper Technologies (diversified industrial/software compounder, ~4-6%), KKR & Co (alternative asset manager with compounding AUM, ~4-6%), and Brookfield Asset Management (~3-5%). The portfolio is characterized by businesses with high returns on equity (typically 20-40%+), ass...
Chuck Akre is one of the most relevant investors to our approach. His philosophy of finding 'compounding machines' using the three-legged stool framework is nearly perfectly aligned with our focus on 'fundamentally great companies with secular tailwinds.' His extreme concentration (20-25 positions), very long holding periods (10+ years), patient temperament, and emphasis on downside protection through business quality rather than valuation discounts all match our approach. His portfolio is a treasure trove of idea generation -- every position is a potential candidate for our own analysis. His letters are excellent educational material. The primary gap is AGI awareness: Akre's framework does not explicitly incorporate technological disruption or AGI risk/opportunity. His portfolio includes ...
Sir Christopher Hohn (born 1966) is a British billionaire investor and the founder and managing partner of The Children's Investment Fund Management (TCI), a London-based hedge fund he co-founded in 2003. Hohn was educated at the University of Southampton (accounting and finance) and Harvard Business School (MBA, Baker Scholar -- top 5% of class). Before founding TCI, he worked at Perry Capital in New York, a value-oriented hedge fund. TCI stands for 'The Children's Investment Fund' because it was originally structured to donate a portion of profits to the Children's Investment Fund Foundation (CIFF), a charitable organization co-founded by Hohn focused on improving the lives of children in developing countries. CIFF has become one of the largest private foundations in the world, with over...
Hohn runs an extremely concentrated, quality-focused portfolio of businesses with durable competitive advantages, high returns on capital, and strong free cash flow generation. His approach combines elements of value investing, quality investing, and shareholder activism. Key principles: (1) Own very few businesses (9 positions as of Q4 2025) -- the ultimate in concentration; (2) Focus on monopoly/oligopoly-like businesses with high barriers to entry -- payment networks (Visa), credit rating agencies (Moody's, S&P Global), financial data providers, railroads (Canadian Pacific, Canadian National), infrastructure (GE Aerospace, Ferrovial); (3) Activist engagement -- TCI is willing to push management teams to improve capital allocation, cut costs, and return capital to shareholders. Famous ac...
Among the most concentrated portfolios of any institutional investor in the world. As of Q4 2025, TCI holds only 9 positions with a portfolio value of $53.6 billion. Top 5 holdings: GE Aerospace (27.3%), Visa (18.1%), Microsoft (15.1%), Moody's (12.7%), S&P Global (11.5%). The remaining positions include Canadian Pacific Kansas City, Alphabet, Ferrovial, and Canadian National Railway. The top 3 positions represent over 60% of the portfolio. This is extreme concentration -- effectively a 9-stock, $53.6B fund. Sector allocation: industrials (30%), financial services/payments (26%), technology (15%), transportation (15%), infrastructure (14%). The portfolio is characterized by monopoly/oligopoly businesses with pricing power, high returns on invested capital, and recurring revenue. Almost no ...
Exceptional. TCI is widely considered one of the best-performing hedge funds in history. Since inception in 2003, TCI has generated estimated annualized returns of approximately 18-20%+ net of fees, dramatically outperforming the S&P 500. Notable periods: TCI suffered in 2008 (estimated -25 to -30% due to ABN AMRO fallout and the financial crisis), but recovered strongly and has been on a remarkable multi-year winning streak. From approximately 2012 to 2025, TCI has compounded at an extraordinary rate, driven by its concentrated positions in Visa, Moody's, Microsoft, and other compounders. The fund's Q4 2025 return was 3.01%, and it manages $53.6B -- the growth from a relatively small base to $53.6B in assets has been largely driven by performance rather than inflows (TCI has been largely ...
Low transparency, typical of London-based hedge funds. TCI files US 13F reports (covering US-listed holdings), which is the primary source of portfolio information. However, TCI does not publish investor letters publicly, Hohn rarely gives interviews, and detailed performance data is not publicly available. The fund is closed to new investors, so there is limited need for marketing transparency. Hohn is more visible on climate/ESG issues, where he has published open letters and spoken at conferences, but this is advocacy rather than investment transparency. The 13F filings are extremely informative given TCI's concentration -- with only 9 holdings, the 13F reveals essentially the entire portfolio (though non-US holdings like Ferrovial may not appear). Overall, the portfolio is quite transp...
High integrity with some controversy. On the positive side: Hohn's philanthropic commitment through CIFF is genuine and substantial -- billions of dollars have been donated to children's causes globally. He was knighted for this work. He invests his own capital alongside investors. His concentration demonstrates genuine conviction -- he puts his money where his mouth is. He has been consistent in his quality-focused philosophy for two decades. On the negative side: The ABN AMRO campaign is controversial -- while profitable for TCI, many argue it contributed to the destabilization of European banking and the financial crisis. Hohn's divorce from Jamie Cooper-Hohn in 2014 was one of the largest in British history (she received approximately $530M), and the proceedings revealed details about ...
As of Q4 2025: GE Aerospace ($14.6B, 27.3%), Visa ($9.7B, 18.1%), Microsoft ($8.1B, 15.1%), Moody's ($6.8B, 12.7%), S&P Global ($6.2B, 11.5%), Canadian Pacific Kansas City, Alphabet/Google, Ferrovial, Canadian National Railway. Historical positions: CSX Corporation, ABN AMRO, Charter Communications, Airbus. The portfolio reflects extreme concentration in monopoly/oligopoly businesses with pricing power.
Very high relevance. Chris Hohn and TCI represent one of the closest alignments with our investment philosophy among all investors analyzed. Key alignments: (1) Extreme concentration -- 9 positions is even more concentrated than our ideal; (2) Long holding periods -- positions held for many years; (3) Focus on businesses with durable competitive moats, pricing power, and high ROIC; (4) Quality over cheapness -- willing to pay fair prices for exceptional businesses; (5) Activist engagement to improve capital allocation (similar to our second-stage analysis interest in management quality). Key divergences: (1) TCI is a hedge fund with a different fee structure and access profile; (2) Hohn's portfolio has limited direct AI/AGI exposure -- Microsoft and Alphabet are the only tech-adjacent hold...
John Huber is the founder and portfolio manager of Saber Capital Management, a value-focused investment firm based in Raleigh, North Carolina. He previously worked in real estate private equity before transitioning to public equity investing. He ran the influential value investing blog 'Base Hit Investing' (basehitinvesting.com) where he wrote extensively about concentrated value investing, competitive advantages, and capital allocation — the blog attracted a significant following in the value investing community. He is deeply influenced by Warren Buffett, Charlie Munger, and the Berkshire Hathaway approach to investing. He has appeared on numerous value investing podcasts and at conferences. He manages money for a small number of high-net-worth clients and runs a highly concentrated portf...
Huber's philosophy is deeply Buffett-influenced but adapted for the modern era. Key tenets: (1) Extreme concentration — he typically holds only 5-8 positions, with top 3 often representing 60-80% of the portfolio. (2) Focus on high-quality businesses with durable competitive advantages and high returns on capital. (3) 'One-foot bars' — he looks for simple, understandable investments where the odds are heavily in his favor, referencing Buffett's quote about not jumping over 7-foot bars. (4) Long-term holding — he holds positions for years, not months. (5) Margin of safety — buying good businesses at reasonable prices, not trying to buy mediocre businesses at cheap prices. (6) Emphasis on owner-operator mindset — thinking about stocks as ownership stakes in businesses. He has evolved from tr...
Extremely concentrated — typically 5-8 positions with massive conviction in top holdings. Based on historical 13F filings, Saber Capital has held large positions in Berkshire Hathaway (often 20-40% of portfolio), Alphabet/Google, Meta/Facebook, and other high-quality businesses. The portfolio is long-only, no leverage, no shorting. He favors companies with network effects, high switching costs, and strong competitive positions. The AUM is relatively small (estimated $50-200M range), which allows him to be nimble but also means he focuses on large-cap, liquid names. His turnover is very low — he holds positions for multiple years and only trades when valuations become extreme.
Saber Capital has generated strong returns since inception, generally outperforming the S&P 500 over most multi-year periods. Exact performance numbers are not widely publicized as it is a private fund. His blog writing and public commentary have demonstrated strong analytical ability, particularly his early recognition of the quality and durability of businesses like Google, Meta, and Berkshire. His concentrated approach means returns can be lumpy — very strong in some years, potentially trailing in others — but the long-term compounding has been solid. His willingness to hold large positions in Meta during its 2022 drawdown and benefit from the subsequent recovery speaks to his conviction and process quality.
Moderately transparent. His blog 'Base Hit Investing' was one of the best value investing blogs available, with detailed write-ups on his investment thinking. He has given numerous podcast interviews and conference presentations explaining his approach. However, the blog has been less active in recent years as he focuses on managing money. His 13F filings provide quarterly snapshots of holdings. He writes investor letters but they are not publicly available — they go only to his limited partners. He shares his general philosophy freely but specific positions and thesis details are reserved for investors.
Very high integrity. He is well-regarded in the value investing community as an honest, thoughtful investor who genuinely cares about getting things right. His blog posts demonstrated intellectual honesty — he discussed his mistakes openly and evolved his thinking publicly. He runs a small fund with significant personal capital invested alongside clients, aligning interests. He does not engage in self-promotion or marketing hype. He is not a fee-extractor — his small AUM and concentrated approach suggest he genuinely cares about returns, not asset gathering.
Based on historical 13F filings: Berkshire Hathaway (consistently large position, often 25-40% of portfolio), Alphabet/Google (significant position), Meta/Facebook (significant position, held through 2022 drawdown), and a small number of other high-quality businesses. The portfolio is overwhelmingly concentrated in 3-5 names. He favors businesses with scale advantages, network effects, and strong management. His Berkshire position reflects his deep admiration for the Buffett/Munger model.
Very high relevance. Huber's approach — extreme concentration, long-term holding, focus on high-quality businesses at reasonable prices, no leverage, no shorting — is extremely close to our philosophy. His emphasis on simple, understandable businesses with durable moats aligns perfectly. His portfolio overlap (Berkshire, Alphabet, Meta) suggests similar analytical conclusions about where value lies. His 'Base Hit Investing' approach — looking for high-probability, moderate-upside situations rather than home runs — resonates with our 'little chance of losing money' philosophy. The main gap is AGI awareness — he is primarily a traditional quality-value investor and does not appear to incorporate AGI timelines into his analysis.
Francois Rochon is the founder and portfolio manager of Giverny Capital, a Montreal-based private investment management firm founded in 1993. He is one of Canada's most respected value investors, though relatively unknown outside of Canadian and French-speaking investment circles. Rochon trained as an engineer (Ecole Polytechnique de Montreal) before transitioning to investing, bringing a quantitative and analytical rigor to his approach. He founded Giverny Capital at age 29, naming it after the French village where Claude Monet painted, reflecting his passion for art and beauty (he is also an avid art collector). Giverny Capital manages assets for a select group of private clients and institutional accounts, with estimated AUM of approximately $500 million to $1 billion. Rochon also manag...
Rochon's philosophy is deeply Buffett-influenced but with his own distinctive emphasis. His key principles: (1) Buy wonderful businesses at fair prices -- he seeks companies with durable competitive advantages (brands, network effects, switching costs, scale advantages), high returns on equity (targeting 15%+ ROE), and the ability to reinvest earnings at attractive rates. He strongly prefers 'compounders' -- businesses whose intrinsic value grows at 10-15%+ annually through organic growth and intelligent capital allocation. (2) Long-term holding -- his average holding period is 5-10+ years. He frequently holds positions for decades. He believes the passage of time is the greatest friend of quality businesses and the greatest enemy of mediocre ones. (3) Concentrated portfolio -- he typicall...
Concentrated, quality-focused, primarily US equities despite being Canada-based. Rochon typically holds 20-25 positions with meaningful concentration in top holdings. The portfolio leans toward US mid-to-large-cap quality compounders: consumer brands, financial services, technology, healthcare, and specialty retail. He has historically favored businesses like Berkshire Hathaway (a long-term core position), Five Below, Constellation Software, Carmax, Dollar General, and various other compounders. His portfolio construction is bottom-up and sector-agnostic. He is entirely long-only, no leverage, no shorting, no derivatives. Turnover is low -- he trades infrequently and holds positions for many years. He manages private client accounts rather than a mutual fund, giving him flexibility and fre...
Excellent long-term track record spanning 30+ years. From 1993 to 2024, Rochon's US equity portfolio has compounded at approximately 15-16% annualized, significantly outperforming the S&P 500 over the same period. His annual letters document this performance year by year with full transparency. He has outperformed the S&P 500 in approximately two-thirds of calendar years, demonstrating consistent stock selection skill. His best years have been during periods when quality compounders are in favor; his worst years have been during value/momentum rotations. His 30+ year track record is one of the longest continuous records among active managers who have meaningfully outperformed their benchmark. The compounding over three decades means that early investors have seen their capital multiply app...
Very high transparency. Rochon publishes detailed annual letters that are freely available and provide: (1) full year-by-year performance vs benchmark going back to 1993, (2) detailed discussion of individual holdings and investment theses, (3) honest analysis of mistakes and lessons learned, (4) philosophical reflections on investing, rationality, and human nature. These letters are among the most thoughtful and transparent in the investment industry. He also files 13F reports quarterly (for US holdings above reporting thresholds). He speaks at investment conferences, participates in interviews (primarily in French-Canadian media), and is accessible to clients. He is not a self-promoter and does not seek media attention, but his work is available to anyone who seeks it. Fee structure is t...
Very high integrity. Rochon has managed Giverny Capital for 30+ years with no ethical scandals, regulatory issues, or conflicts of interest. He invests substantially alongside his clients. He has deliberately kept AUM manageable rather than maximizing fees, forgoing potential revenue to preserve investment flexibility. His annual letters are devoid of spin, self-promotion, or marketing language -- they are genuine intellectual documents. He openly discusses mistakes (positions that lost money, missed opportunities) with the same candor as successes. He has maintained the same investment philosophy for 30+ years without style drift, which is extremely rare. He appears genuinely motivated by the intellectual challenge of investing and the responsibility of managing client capital, rather tha...
Based on 13F filings and annual letters, notable holdings have included: Berkshire Hathaway (long-term core position), Five Below (specialty retail compounder), Constellation Software (Canadian serial acquirer, a favorite), CarMax (auto retail with technology advantages), Dollar General (value retail compounder -- later sold/reduced amid operational challenges), Meta Platforms, Alphabet/Google, Visa, Booking Holdings, and various US mid-cap quality compounders. He has historically held some Canadian names like Alimentation Couche-Tard (Circle K parent), Dollarama, and CGI Group. The portfolio is characterized by high-quality businesses with strong competitive positions, high returns on equity, and long reinvestment runways. He tends to favor businesses he can understand deeply and hold for...
Francois Rochon is highly relevant to our approach. His 30+ year track record of 15%+ annualized returns using a concentrated quality compounder strategy demonstrates that our type of approach works over very long time horizons. His emphasis on business quality, management integrity, and long-term holding aligns closely with our philosophy. His annual letters are excellent educational material, providing a transparent record of how a thoughtful investor thinks about businesses, mistakes, and markets over three decades. His portfolio provides a rich source of potential investment ideas, particularly in the US mid-cap compounder space that we might otherwise overlook. Key limitations: (1) relatively small AUM means his 13F may not capture all positions; (2) no explicit AGI/technology disrupt...
Terry Smith is the founder, CEO, and CIO of Fundsmith, a London-based investment management firm he launched in 2010. Before founding Fundsmith, Smith had a distinguished career in the City of London: he was a top-rated banking analyst at various brokerages in the 1980s, became CEO of Collins Stewart (a stockbroking firm) in 2003, and authored the influential book 'Accounting for Growth' (1992), which exposed aggressive accounting practices at major UK companies -- the book was so controversial that his employer at the time (UBS Phillips & Drew) fired him for it, and several of the companies he criticized subsequently went bankrupt, vindicating his analysis. This episode cemented his reputation as a fearless, independent thinker. Fundsmith Equity Fund launched in November 2010 with the rad...
Smith's philosophy is distilled into three deceptively simple rules: (1) Buy good companies -- he looks for businesses with high returns on capital (ROCE), strong competitive advantages (pricing power, brand strength, network effects), and resilient business models that can withstand economic cycles. He has a strong preference for consumer staples, healthcare, technology platforms, and other businesses with recurring revenue and low capital intensity. He explicitly avoids banks, utilities, commodity producers, airlines, and any business that requires heavy capital investment or is subject to regulatory price controls. (2) Don't overpay -- he uses free cash flow yield as his primary valuation metric, seeking a reasonable price rather than a bargain basement one. He believes overpaying for q...
Moderately concentrated. Fundsmith Equity Fund typically holds 25-30 positions, with the top 10 representing approximately 50-55% of assets. The portfolio is global but heavily skewed toward US-listed companies (typically 65-70% US), with meaningful European exposure (15-20%) and some emerging market exposure through global businesses listed in developed markets. Sector exposure is dominated by consumer staples (historically 25-35%), healthcare/pharma (15-20%), technology (15-25%), and industrials (10-15%). He avoids financials, energy, materials, and utilities almost entirely. The portfolio is entirely long-only, no leverage, no derivatives, no shorting. Holding periods are very long -- many positions have been held since the fund's inception in 2010. He runs a 'quality compounders' portf...
Excellent track record since inception. Fundsmith Equity Fund (T Class Accumulation) has compounded at approximately 15-16% annualized from November 2010 through 2024, significantly outperforming the MSCI World Index over the same period. Performance by year has been remarkably consistent: the fund outperformed in most years, with only 2022 (-13.8%) and 2023 being notable underperformance years. The fund's worst calendar year was 2022, when rising interest rates hit the valuations of quality growth stocks. However, 2023-2024 saw strong recovery. Since inception through late 2024, the fund has roughly 7x'd investor capital, turning GBP 1 into approximately GBP 6.80+ (T class accumulation). This represents one of the best track records among major European fund managers over this period. Ris...
High transparency. Smith publishes a detailed annual letter to shareholders (the 'Owner's Manual') that explains performance attribution, discusses individual holdings, analyzes mistakes, and provides data on portfolio quality metrics (aggregate ROCE, FCF margins, etc.). He also writes monthly factsheets with top holdings and attribution. He holds an annual shareholder meeting (broadcast online) where he presents for 1-2 hours and takes extensive Q&A. He is active on social media (particularly Twitter/X), where he comments on markets, investing principles, and occasionally criticizes companies or other fund managers. Fee structure is transparent: no performance fees, no upfront charges, with an ongoing charge of approximately 0.94-1.05% depending on share class. He has been vocal about the...
High integrity with some caveats. Smith's willingness to be fired over 'Accounting for Growth' demonstrates genuine intellectual courage and prioritization of truth over career safety. He invests substantially in his own fund (reportedly over GBP 250 million of personal capital), creating strong alignment. He has been consistent in his philosophy over 15 years of managing Fundsmith. He has never engaged in fraudulent behavior or regulatory violations. He is genuinely passionate about investing and contemptuous of fee extraction. However, he can be abrasive and dismissive of legitimate criticism, and his public persona sometimes veers into self-promotion. His criticisms of ESG investing, while often analytically valid, have been unusually combative. He has also been criticized for performan...
Top holdings as of recent filings include: Meta Platforms (~8-9%), Microsoft (~7-8%), Novo Nordisk (~6-7%), LVMH (~5-6%), Stryker (~4-5%), Philip Morris International (~4-5%), L'Oreal (~4-5%), Visa (~4-5%), IDEXX Laboratories (~3-4%), and Estee Lauder/Waters Corporation/other quality names. Historical core positions include Unilever (sold after public criticism of management), PayPal (sold after deterioration), Facebook/Meta (held through the 2022 drawdown and rewarded handsomely). The portfolio is characterized by high ROCE (aggregate portfolio ROCE typically 25-30%+), high gross margins (typically 60%+), and low capital intensity. Smith explicitly screens for these metrics. His willingness to hold Meta through its 2022 crash and increase his position demonstrated genuine conviction and l...
Terry Smith is highly relevant to our approach. His 'buy good companies, don't overpay, do nothing' philosophy aligns closely with our focus on quality compounders held for the long term. His concentration level (25-30 positions) is somewhat higher than our ideal but still concentrated by industry standards. His forensic accounting background is directly applicable to our 'balance sheet deep dive' analysis area. His emphasis on high ROCE, FCF generation, and management quality matches our framework. His portfolio includes several AGI-relevant names (Meta, Microsoft) but his selection is based on quality metrics rather than explicit AGI thesis. His annual letters and shareholder presentations are excellent educational material. Key gaps: (1) his portfolio is larger (25-30 positions) than ou...
Christopher Bloomstran is the president, CIO, and portfolio manager of Semper Augustus Investments Group, based in St. Louis, Missouri. He founded the firm in 1998 after working at George Washington University's endowment fund and other investment roles. Semper Augustus (named after the famed tulip variety from the Dutch Tulip Mania -- a deliberate reference to the dangers of speculation) manages approximately $1-2 billion in assets for high-net-worth individuals and institutional accounts. Bloomstran is best known in the investment community for two things: (1) his extraordinarily detailed and voluminous annual letters, which frequently exceed 100 pages and contain some of the most rigorous financial analysis in the industry, and (2) his deep, proprietary analysis of Berkshire Hathaway's ...
Bloomstran's philosophy is deep value/quality hybrid with extreme emphasis on fundamental analysis rigor. His key principles: (1) Concentrated ownership of the best businesses -- he owns a small number of companies (typically 15-25 positions) that he understands deeply. His ideal business has high returns on capital, durable competitive advantages, excellent management, and the ability to reinvest at attractive rates. (2) Forensic-level financial analysis -- Bloomstran goes deeper than almost any other investor on financial statement analysis. He adjusts reported financials for accounting distortions (stock-based compensation, acquisition accounting, off-balance-sheet items, pension adjustments), reconstructs economic reality from GAAP data, and builds multi-decade financial models. His an...
Concentrated. Semper Augustus typically holds 15-25 positions, with Berkshire Hathaway historically representing an enormous position (often 25-40%+ of the portfolio). The portfolio is heavily tilted toward businesses with tangible assets, strong balance sheets, and durable earnings power. Beyond Berkshire, positions tend to be in financials (banks, insurance), industrials, energy, and other sectors where Bloomstran can apply his forensic accounting skills most effectively. He is less likely to own technology companies (where traditional accounting metrics are less informative) and more likely to own businesses with clear balance sheets and predictable cash flows. The portfolio is entirely long-only, no leverage, no shorting. Turnover is low. He runs separately managed accounts for clients...
Strong long-term track record, though heavily influenced by Berkshire Hathaway exposure. Since founding Semper Augustus in 1998, Bloomstran has generated returns that have broadly tracked or modestly outperformed the S&P 500 over the full period. His performance has been cyclical: he underperformed during the late 1990s tech bubble (due to avoiding overvalued tech), outperformed during the 2000-2003 bear market and 2008-2009 financial crisis, underperformed during the 2013-2020 growth/momentum bull market, and has performed well in 2021-2025 as value/quality have recovered. His returns are less spectacular than some other investors on this list (partly due to the large Berkshire position, which has generated excellent but not explosive returns) but are highly credible and achieved with low...
Exceptionally high transparency. Bloomstran's annual letters are among the most detailed and transparent in the investment industry -- frequently exceeding 100 pages (sometimes 150+ pages) of rigorous financial analysis, position-by-position discussion, mistake analysis, and philosophical commentary. These letters are distributed to clients and available to the public upon request. They are effectively book-length treatises on investment analysis. His Berkshire Hathaway valuation analysis alone often exceeds 50 pages. He also speaks at investment conferences (notably the Value Investor Conference and various Berkshire-adjacent events), gives interviews, and engages substantively on social media (Twitter/X), where he shares charts, data, and analytical insights. He is generous with his time...
Very high integrity. Bloomstran has maintained his investment philosophy and analytical rigor for 25+ years without compromise. He avoided the tech bubble of 1999-2000 despite severe career pressure to participate, demonstrating genuine conviction over career management. He invests substantially alongside his clients. He has never been involved in ethical scandals, regulatory issues, or conflicts of interest. His letters are paragons of intellectual honesty -- he discusses mistakes at length, acknowledges uncertainty, and does not cherry-pick favorable periods for performance comparisons. He has deliberately kept AUM manageable to preserve performance. He is known in the value investing community for his generosity in sharing ideas and analysis. His detailed Berkshire analysis, which he co...
Berkshire Hathaway is and has always been the dominant position, representing approximately 25-40%+ of the portfolio at various times. Bloomstran's analysis of Berkshire's intrinsic value has been a core competency and conviction driver. Other notable positions (based on 13F filings) have included: Alphabet/Google, Wells Fargo (sold after governance scandals), Bank of America, JPMorgan Chase, various energy companies (during periods of undervaluation), Markel Corporation, and other value-oriented financial and industrial companies. The portfolio tends to include businesses with strong balance sheets, tangible book value, and identifiable earnings power. He has historically underweighted technology relative to the S&P 500 but has increased tech exposure in recent years (particularly Alphabe...
Christopher Bloomstran is moderately to highly relevant to our approach. His forensic-level financial analysis is directly applicable to our 'balance sheet deep dive' analysis area -- his approach to stripping away accounting distortions and finding true economic reality is exactly the kind of analysis we want to perform. His Berkshire intrinsic value work is a masterclass in multi-business valuation that we can learn from. His emphasis on capital allocation analysis aligns with our management assessment framework. His long-term orientation and concentration match our approach. His annual letters are among the most educational documents available for developing deep analytical skills. Key limitations: (1) his heavy Berkshire concentration means his portfolio is less useful as an idea sourc...
Seth Klarman (b. 1957) is the founder and CEO of The Baupost Group, a Boston-based hedge fund he started in 1982 with $27 million. He graduated from Cornell University and Harvard Business School. Baupost has grown to manage approximately $25-30 billion in AUM, making it one of the largest hedge funds in the world. Klarman is the author of 'Margin of Safety: Risk-Averse Value Investing Strategies for the Thoughtful Investor' (1991), a book so revered in value investing circles that out-of-print copies sell for $1,000-$2,000. He is widely considered one of the greatest value investors of his generation, often called the 'Oracle of Boston' as a parallel to Buffett's 'Oracle of Omaha.'
Klarman's philosophy centers on absolute return investing with a laser focus on downside protection. Core principles: (1) Margin of safety is paramount — buy assets at a significant discount to intrinsic value to protect against errors and bad luck. (2) Risk is not volatility but the probability of permanent capital loss. (3) Cash is a residual — if you can't find cheap assets, hold cash rather than reaching for returns. Baupost has historically held 30-50% cash when opportunities are scarce. (4) Go where others won't — distressed debt, complex securities, real estate, private investments, not just public equities. (5) Bottom-up, fundamental analysis. (6) Patient, contrarian — willing to look wrong for extended periods. (7) Focus on absolute returns, not relative performance vs benchmarks....
Moderately concentrated in public equities (typically 15-25 positions in the 13F), but Baupost is a multi-asset fund investing across public equities, distressed debt, private investments, and real estate. The 13F only shows the public equity portion, which may represent 30-50% of total AUM. Holding periods vary — some positions held for years, others are more opportunistic. Turnover is moderate. Baupost is known for holding large cash positions (sometimes 30-50% of the portfolio) when opportunities are scarce, which is a distinguishing feature. Recent top 13F holdings have included Liberty Broadband, Qorvo, ViaSat, Intel, and Willis Towers Watson.
Baupost has compounded at approximately 19-20% annualized net of fees since inception in 1982, vs roughly 10-11% for the S&P 500 over the same period. Remarkably, Klarman has achieved this with significantly lower volatility and drawdowns than the market, and with an average of ~30% cash drag. The fund has had very few down years — reportedly only 3-4 losing years in 40+ years. The Sharpe ratio has been exceptional. However, more recent performance (2015-2024) has reportedly been more mixed, with the fund underperforming in strong bull markets (expected given the conservative approach and large cash holdings). The fund returned capital to investors multiple times when AUM grew too large for available opportunities.
Moderate transparency. Klarman does not write regular public letters, but his annual letters to Baupost investors are occasionally leaked and are widely read in the investment community. He rarely gives interviews but when he does, they are thoughtful and substantive. His book 'Margin of Safety' remains the most comprehensive articulation of his philosophy. He has spoken at industry conferences and business schools. 13F filings provide a window into the public equity portion of the portfolio. He is not a public figure by choice — he values privacy — but his ideas are well-documented through the book, leaked letters, and occasional speeches.
Very high integrity. Klarman has the vast majority of his personal wealth invested in Baupost alongside his investors. He has returned capital to investors multiple times when AUM grew beyond what he could deploy effectively — an extremely rare act in the hedge fund industry where fees are based on AUM. No scandals, no regulatory issues, no conflicts of interest. He is known for his intellectual honesty and willingness to admit mistakes. He has been transparent about periods of underperformance. He is also a significant philanthropist, particularly in education and Jewish community organizations.
Recent and historical notable holdings include: Liberty Broadband, Qorvo, ViaSat/Viasat, Intel, Willis Towers Watson, Bausch Health (formerly Valeant — a rare mistake), Theravance Biopharma, PG&E (bought during bankruptcy proceedings), Athabasca Oil, various distressed debt positions (Lehman Brothers claims, Enron claims, Argentine sovereign debt). Baupost is known for investing in complex, messy situations that most investors avoid — bankruptcies, litigation, restructurings, and special situations. The portfolio tends to be contrarian and often looks very different from typical long-only equity funds.
Very high alignment. Klarman's obsessive focus on margin of safety and 'little chance of losing money' is essentially identical to our floor price philosophy. His willingness to hold cash when opportunities are scarce, his focus on absolute rather than relative returns, and his patient contrarian approach all match our philosophy. Key differences: (1) Baupost invests across many asset classes, not just public equities, so the 13F is an incomplete picture. (2) Baupost is more diversified than our target of 'very few investments.' (3) Klarman tends to avoid technology stocks and may not be well-positioned for AGI disruption analysis. (4) His portfolio is oriented toward complex special situations rather than 'fundamentally great companies with secular tailwinds.'
Jean-Marie Eveillard (born 1940) is a French-born American value investor who managed the SoGen International Fund (later renamed First Eagle Global Fund) from 1979 to 2004, a remarkable 25-year tenure. He returned briefly to manage the fund from 2007-2009 during the financial crisis before retiring permanently. Born in Poitiers, France, he studied at Ecole des Hautes Etudes Commerciales (HEC Paris). He began his career at Societe Generale in Paris in the 1960s, transferring to New York in 1968. He took over the SoGen International Fund in 1979 when it had approximately $15 million in assets and built it into a multi-billion dollar fund. He was inducted into the Morningstar Fund Manager Hall of Fame and is considered one of the great international value investors of the 20th century. He is...
Eveillard is a Graham-and-Dodd value investor of the purest type, applied globally. His core principles: (1) Margin of safety above all — he would rather miss an opportunity than risk permanent loss of capital. His famous quote: 'I would rather lose half my shareholders than lose half my shareholders' money.' (2) Absolute return orientation — he never benchmarked against indices, focusing solely on preserving and growing capital in real terms. (3) Gold as portfolio insurance — he pioneered the use of gold and gold mining stocks as a hedge within an equity fund, a practice continued by his successors. (4) Willingness to hold cash — during the late 1990s tech bubble, he held up to 20-30% cash rather than invest in overvalued securities. This caused massive redemptions and underperformance bu...
Under Eveillard, the First Eagle Global Fund was moderately concentrated, typically 80-150 holdings with meaningful position sizes in top holdings. He maintained a distinctive allocation to gold (5-15% of fund) and was willing to hold significant cash positions (up to 20-30% in expensive markets). His geographic allocation was truly global — US, Europe, Japan, and emerging markets. He favored asset-rich businesses, companies with strong balance sheets, and situations where he could buy at a significant discount to net asset value. He avoided highly leveraged companies, unproven business models, and situations where he couldn't estimate a margin of safety. His portfolio turnover was low, reflecting his long-term orientation.
Outstanding long-term track record. From 1979 to 2004, the SoGen International / First Eagle Global Fund compounded at approximately 15% per year, dramatically outperforming global equity indices. This was achieved with significantly lower volatility and drawdowns. During the 2000-2002 tech crash, his fund gained approximately 30% cumulatively while the S&P 500 fell roughly 50% and the MSCI World fell approximately 45%. This vindication of his discipline during the bubble period is one of the great stories in mutual fund history. However, from 1997-1999, he significantly underperformed as tech stocks soared and his conservative approach was out of favor. He lost approximately 40% of fund assets to redemptions during this period. When he was proven right, assets flowed back and eventually g...
Moderate transparency. Eveillard wrote thoughtful but infrequent letters and commentaries. He gave periodic interviews and speeches at Columbia Business School and value investing conferences. He was honest and direct about his views, including his willingness to criticize market excesses. His investment philosophy was well-articulated in various interviews and presentations. However, he was not as prolific a writer as Buffett or other famous investors. Since retirement, he has been less publicly active but occasionally appears at value investing events.
Exceptional integrity — among the highest in the mutual fund industry. His willingness to lose half his investors rather than half their money during the late 1990s bubble is a defining example of putting fiduciary duty above business considerations. When other managers style-drifted to chase tech stocks, he maintained his discipline at enormous personal and professional cost (massive fund outflows, pressure from management). He was vindicated spectacularly. He invested his own money alongside shareholders. He has never been involved in any ethical controversy or regulatory issue. He is universally respected in the value investing community for his moral character and intellectual honesty.
During his tenure, notable holdings included: gold bullion, gold mining stocks (Newmont, Barrick), various European industrial and consumer companies, Japanese companies trading below book value, Philip Morris, Berkshire Hathaway, and numerous small and mid-cap companies globally where he found deep value. He was especially known for finding value in out-of-favor markets — Japan in the late 1990s/early 2000s, European companies during various crises, and emerging market companies trading at significant discounts to asset value.
Very high relevance. Eveillard is one of the most philosophically aligned investors to our approach. His absolute return orientation, margin of safety discipline, willingness to hold cash, focus on avoiding permanent loss of capital, and long-term horizon all match our philosophy closely. His famous quote about preferring to lose shareholders rather than their money perfectly captures our 'little chance of losing money' approach. His gold allocation as tail risk insurance is worth studying. His behavior during the tech bubble is a masterclass in discipline under pressure. As a retired/legacy investor, his current holdings are not directly actionable, but his philosophy, frameworks, and historical decisions provide immense learning value. His main limitation for us is that he managed a rela...
Pat Dorsey is the founder and portfolio manager of Dorsey Asset Management, a registered investment adviser based in Chicago that manages a single concentrated global equity strategy. Before founding Dorsey Asset Management in 2015, he spent 12 years at Morningstar, where he served as Director of Equity Research, overseeing more than 100 equity analysts. At Morningstar, he was the architect of their 'economic moat' rating methodology -- the systematic framework for evaluating competitive advantages that Morningstar uses to rate every stock they cover. He is the author of two widely-read investment books: 'The Five Rules for Successful Stock Investing' (2003) and 'The Little Book That Builds Wealth' (2008), both focused on identifying and profiting from durable competitive advantages. He is...
Dorsey's philosophy is deeply rooted in three pillars: (1) Economic moats -- he invests only in businesses with durable competitive advantages (switching costs, network effects, intangible assets, cost advantages, efficient scale). This is his primary filter and non-negotiable criterion. (2) Reinvestment runways -- he strongly prefers businesses that can reinvest capital at high incremental rates of return for extended periods. He believes the true compounding power of an investment comes not just from having a moat, but from having a long runway to deploy capital within the moat. This distinguishes him from many moat-focused investors who own mature, slow-growth businesses. Dorsey specifically seeks companies that are both moat-protected AND growing by reinvesting at high returns. (3) Val...
Highly concentrated -- Dorsey Asset Management typically holds 15-25 positions, with the top 10 representing an estimated 60-75% of assets. Global mandate -- he invests across US, European, and emerging market equities, wherever he finds the best moat + reinvestment combination. Sectors tend to be tilted toward information services, financial exchanges, software, specialty industrials, and other asset-light businesses with high returns on invested capital. He avoids capital-intensive businesses, commodity producers, and companies without durable competitive advantages. Long-only, no leverage, no shorting. Holding periods are very long -- he seeks to hold compounders for 5-10+ years and has noted that he would ideally never sell a great compounder. Turnover is low. The strategy is run as se...
Dorsey Asset Management has been operating since 2015, giving approximately 10 years of track record. As a private investment adviser (not a mutual fund), detailed performance data is not publicly available. However, based on the quality of his investment framework, his portfolio composition (high-quality compounders), and the strong performance of the types of businesses he favors (moat-rich, high-ROIC compounders have dramatically outperformed the market over this period), informed estimates suggest strong performance. His intellectual track record at Morningstar is impeccable -- the moat methodology he built has been validated extensively, and the wide-moat stocks he championed have outperformed the broad market over virtually every multi-year period. His books remain among the best pra...
Moderate transparency. Dorsey Asset Management files 13F reports quarterly, disclosing public equity holdings above the reporting threshold. However, as a private adviser, detailed performance numbers, investor letters, and portfolio analytics are not publicly available. Dorsey himself is moderately visible through podcast interviews, conference presentations, and his books, where he shares his intellectual framework generously. His investment thinking is highly transparent -- anyone who reads his two books and watches his presentations understands exactly how he thinks. But the specific portfolio results and decision-making process are private. Fee structure: typical SMA advisory fee, likely 1-1.5% of AUM, no performance fee.
Very high integrity. Dorsey left a high-profile, well-compensated position at Morningstar to start his own firm and put his money where his mouth is -- managing a concentrated portfolio based on the principles he spent a decade writing about and teaching. He has been completely consistent in his investment philosophy across books, interviews, and (from what can be observed) portfolio construction. He intentionally keeps AUM small, forgoing higher fees to preserve investment flexibility -- a strong signal of investor alignment over fee maximization. He has no known ethical issues, regulatory problems, or conflicts of interest. His books are intellectually honest and practical, not self-promotional or misleading. He openly discusses his mistakes and what he learned from them (particularly th...
Based on 13F filings, Dorsey's portfolio has included positions in companies like MSCI Inc, S&P Global, Verisk Analytics, TransUnion, MarketAxess, Fair Isaac Corporation (FICO), CoStar Group, Roper Technologies, Brookfield Asset Management, Heico Corporation, and various European and global compounders. The portfolio is characterized by high-ROIC, asset-light businesses with strong competitive positions and long reinvestment runways. Many of his holdings are in the financial data/analytics, software, and specialty industrial sectors -- businesses that benefit from network effects, switching costs, or intangible assets. He tends to avoid mega-cap tech in favor of less-followed, high-quality mid-cap compounders.
Pat Dorsey is extremely relevant to our approach. His emphasis on economic moats and reinvestment runways directly supports our focus on 'fundamentally great companies with secular tailwinds.' His concentration level (15-25 positions) is very close to our ideal. His long-only, no-leverage structure matches perfectly. His long holding periods (5-10+ years) align with our horizon. His valuation discipline is compatible with our floor price approach, though he focuses more on intrinsic value growth than on absolute downside protection. His global mandate gives us exposure to opportunities we might miss with a US-only lens. His intellectual framework (moats + reinvestment + capital allocation) is perhaps the most directly applicable framework to our investment process. Key gaps relative to our...
Thomas Russo is a Managing Member of Gardner Russo & Quinn, a registered investment advisory firm based in Lancaster, Pennsylvania. He graduated from Dartmouth College and holds a JD/MBA from Stanford. Russo has been managing money since the mid-1980s, originally as a protege of the legendary investor William Ruane (a Buffett disciple who ran the Sequoia Fund). He joined Semper Vic Partners (now Gardner Russo & Quinn) around 1989. Russo manages approximately $8-12 billion in assets, primarily for high-net-worth families and institutional clients. He is widely regarded as one of the most disciplined long-term compounders in the investment world. Russo is a fixture at Berkshire Hathaway annual meetings and is deeply embedded in the Buffett-Munger intellectual tradition. He is known for coini...
Russo is a quintessential long-term compounder. His philosophy centers on owning global consumer brands with strong competitive moats, pricing power, and the ability to reinvest retained earnings at high rates of return. He is most famous for the concept of 'capacity to suffer' -- he prefers family-controlled or management-led companies that can withstand short-term earnings declines in pursuit of long-term value creation (entering new markets, building brands, investing through downturns). He believes public market short-termism creates opportunities for patient investors. He emphasizes: (1) brands that can be replicated globally (Nestle, Heineken, Richemont); (2) network effects and scale advantages (Mastercard, Visa, Berkshire Hathaway); (3) management teams with a multi-generational mi...
Highly concentrated and extremely low turnover. Gardner Russo & Quinn's 13F typically shows 20-30 positions, with the top 5-7 holdings representing 60-70%+ of the portfolio. His largest positions have been held for 15-25+ years. Key characteristics: (1) Heavy international orientation -- unlike most US managers, a significant portion of his portfolio is in European-listed consumer brands (Nestle, Heineken, Richemont, Compagnie Financiere Rupert) which show up as ADRs or foreign holdings; (2) Massive Berkshire Hathaway position -- typically 15-25% of the portfolio; (3) Payment networks (Mastercard, Visa) -- large, long-held positions; (4) Consumer luxury/staples -- Richemont (Cartier parent), Nestle, Philip Morris International, Heineken; (5) Almost zero technology exposure -- he does not i...
Strong long-term track record spanning 35+ years, though precise performance data is not publicly available since Gardner Russo & Quinn is a private advisory firm. Based on interviews, speeches, and partial disclosures: Russo has compounded capital at approximately 12-15% annualized over his career, which is meaningfully above S&P 500 returns over the same period. His approach shines over very long time horizons -- his Berkshire Hathaway position purchased in the late 1980s/early 1990s has compounded enormously. His Mastercard position, held since the mid-2000s, has been a massive winner (Mastercard stock compounded at roughly 25-30% annually from IPO to present). His international holdings (Nestle, Heineken, Richemont) have been more mixed -- European stocks have generally underperformed ...
Moderate transparency. Gardner Russo & Quinn files 13F reports quarterly, so US-listed holdings are public. Russo gives periodic interviews, speeches at value investing conferences (notably the Value Investor Conference in Omaha, the London Value Investor Conference), and has been featured extensively in value investing literature (The Manual of Ideas, Value Investor Insight). He is articulate and generous with his intellectual framework. However, his European/international holdings (which are significant) do not appear on 13F filings, making his full portfolio only partially visible. He does not publish investor letters publicly, and detailed performance figures are private. His frequent speaking appearances make his philosophy very well-understood even if his exact portfolio is not fully...
Very high integrity. Russo has managed money for families for 35+ years with a consistent philosophy and no scandals. He eats his own cooking -- his personal wealth is invested alongside clients. He is not a self-promoter; his media appearances are educational and philosophical rather than promotional. He charges reasonable fees for a private advisory firm. He has never been involved in any regulatory issues, fraud allegations, or ethical controversies. He is known for his intellectual humility, willingness to admit when positions underperform, and his deep respect for the Buffett-Munger tradition of honest, aligned investing. His clients tend to stay for decades, which is perhaps the strongest testament to his integrity.
Berkshire Hathaway (largest position, 15-25% of portfolio, held 30+ years), Mastercard (major position, held since mid-2000s), Nestle (long-held, global consumer staple), Philip Morris International (pricing power, emerging market growth), Richemont/Compagnie Financiere Rupert (Cartier luxury brand parent, long-held), Heineken (global beer brand, family-controlled), Visa (payment network), Alphabet/Google (one of his few tech-adjacent holdings, relatively newer). The portfolio reflects a strong preference for brands with global reach, pricing power, and family/founder control.
High relevance. Thomas Russo's investment philosophy is strongly aligned with our approach: concentrated portfolios, extreme long-term holding periods, focus on downside protection through business quality, emphasis on competitive moats and pricing power. His 'capacity to suffer' concept resonates with our willingness to hold through drawdowns. His focus on businesses with embedded optionality (growth options the market doesn't price) is similar to our interest in hidden upside potential. Key divergences: (1) Russo has almost no technology exposure, which conflicts with our AGI-aware thesis -- he is unlikely to be positioned for AI/AGI transformation; (2) his European brand focus has underperformed US tech stocks significantly; (3) he does not think in terms of 'floor prices' explicitly, t...
Born in 1952 in Phnom Penh, Cambodia, of Chinese descent. Emigrated to Canada as a young man with very little money. Self-taught investor who worked as a telephone line repairman at Bell Canada while studying investing on his own, devouring the works of Benjamin Graham, Warren Buffett, and other value investing luminaries. In 1981, he started an investment club at Bell Canada with co-workers, pooling their savings. The club's returns were so strong that it eventually became the Chou Associates Fund, formally launched in 1986. Chou never attended business school or obtained any formal financial credentials — he learned entirely through reading and practice. He runs Chou Associates Management Inc. out of a modest office in Toronto with a tiny team. Known for his humility, frugality, and inte...
Deep value investor in the Benjamin Graham tradition with a willingness to venture into distressed and special situations. Chou looks for companies trading at significant discounts to intrinsic value, with a strong emphasis on downside protection and margin of safety. He invests heavily in distressed debt, workout situations, and deeply out-of-favor equities where the risk/reward is asymmetric. His approach is highly contrarian — he buys when others are panicking and is willing to hold positions for years through volatility. Chou emphasizes understanding the balance sheet, looking for hidden assets, and assessing the worst-case scenario before considering upside. He has a particular expertise in analyzing distressed bonds and credit instruments, often buying corporate bonds at deep discoun...
Moderately concentrated with 20-40 positions, but willingness to take large positions (5-15% of fund) in highest-conviction ideas. Invests across the capital structure — equities, distressed bonds, and special situations. Portfolio spans US and Canadian markets with occasional international exposure. Low turnover — many positions held for 3-7+ years. Comfortable with illiquid, obscure, and out-of-favor names that institutional investors avoid. Has held positions in companies like Resolute Forest Products, Overstock.com, EXCO Resources, Sears Holdings, and various distressed energy and resource companies. Also invests in more mainstream names like Berkshire Hathaway. The portfolio tends to look nothing like any index and can have significant tracking error versus benchmarks.
The Chou Associates Fund has one of the best long-term track records in Canadian investing. From inception in 1986 through the mid-2010s, the fund compounded at approximately 12-13% annualized, significantly outperforming the S&P/TSX Composite and S&P 500 over that period. However, the fund went through a brutal stretch from 2014-2020, significantly underperforming as deep value and distressed investing fell deeply out of favor. Energy and resource holdings, distressed debt positions, and contrarian bets suffered during this period. The fund's AUM declined from a peak of over $800M to under $200M as investors fled. This is a pattern common to deep value investors during extended growth-dominated markets. The fund has shown signs of recovery in recent years as value has rotated back into fa...
Very high. Chou writes detailed, candid annual shareholder letters that rival Buffett's in their honesty and educational value. He discusses individual positions, explains his reasoning for purchases and sales, openly admits mistakes, and provides thoughtful commentary on market conditions. The letters are freely available online and are considered some of the best investor letters in Canada. He does not do media tours or self-promotion — the letters speak for themselves. Fund holdings are reported through regulatory filings. Chou does not charge performance fees on the main fund, only a modest management fee, which is unusual and speaks to his alignment with investors.
Very high. Chou's personal story — arriving in Canada with nothing and building a remarkable track record through self-education — speaks to genuine character. He is known for extreme frugality, running a tiny operation with minimal overhead. He eats his own cooking, with a substantial portion of his personal net worth invested in the fund. His fee structure (no performance fees, low management fees) is among the most investor-friendly in the industry. He has never engaged in the kind of asset-gathering behavior common among fund managers — when performance suffered, he did not launch marketing campaigns or change his strategy to chase returns. He has been remarkably consistent in his approach for nearly 40 years. His annual letters are models of intellectual honesty, openly discussing pos...
Historically: Resolute Forest Products, Overstock.com (bought deep in single digits before its multi-bagger run), EXCO Resources, Sears Holdings (bonds and equity), various distressed energy bonds, Berkshire Hathaway, Bank of America warrants, Sprint bonds, and numerous obscure Canadian small-caps. The portfolio often contains names that most investors have never heard of. In recent years, the fund has held positions in technology companies, special situation equities, and distressed credit. Chou has a knack for finding deeply undervalued situations that the market has given up on.
High relevance. Chou's philosophy is closely aligned with ours: emphasis on downside protection, margin of safety, willingness to be contrarian, long-term holding periods, concentrated positions, and intellectual honesty about mistakes. His approach to analyzing balance sheets for hidden assets and liabilities mirrors our floor price philosophy. His willingness to hold cash when no bargains exist is admirable discipline. His shareholder letters are educational gold — worth reading for their analytical frameworks alone. The key difference is his comfort with distressed debt and workout situations, which adds complexity we may not want. He also has no particular focus on AGI or technology disruption, being more of a traditional deep value investor. His recent underperformance during the grow...
Born in India, Aswath Damodaran is a Professor of Finance at NYU Stern School of Business, widely known as the 'Dean of Valuation.' He holds an MBA from UCLA and a PhD from UCLA. He has been teaching at NYU since 1986 and has won the university's Distinguished Teaching Award multiple times. He has written over a dozen books on valuation, corporate finance, and investment philosophy including 'Investment Valuation,' 'Damodaran on Valuation,' 'The Dark Side of Valuation,' 'Narrative and Numbers,' and 'The Little Book of Valuation.' He maintains a hugely influential blog 'Musings on Markets' where he publicly values companies in real-time, showing his full models and assumptions. He is arguably the most influential valuation teacher in the world, with millions of views on his free YouTube lec...
Damodaran's philosophy centers on intrinsic valuation — computing what a business is worth based on its cash flows, growth, and risk. He distinguishes between 'pricing' (what the market will pay) and 'valuation' (what something is intrinsically worth). He emphasizes the interplay of narrative and numbers: every valuation starts with a story about the company's future, which then gets converted into financial inputs. He is agnostic about growth vs. value, arguing the distinction is artificial — all investing is about buying assets for less than they are worth. He insists on intellectual honesty in valuation: acknowledging uncertainty, being transparent about assumptions, and updating when wrong. He publicly values companies like Tesla, Apple, Uber, NVIDIA, and others, showing his models and...
Not a fund manager — manages only his personal portfolio. He invests based on his own DCF valuations and publicly shares his holdings and returns. His portfolio tends to be moderately concentrated across sectors and geographies. He has held positions in companies like Tesla (bought when undervalued, sold when his valuation was exceeded), Apple, Facebook/Meta, Alphabet, and various international stocks. He does not trade frequently and holds positions for years typically. His approach is purely bottom-up based on individual company valuations. He has no leverage, no shorting — purely long positions in publicly traded equities.
As an academic, Damodaran's track record is not measured like a fund manager's. However, he has publicly shared his personal portfolio returns which have been competitive with the S&P 500 over long periods. His real track record is intellectual influence: he has literally taught the world how to value companies. His public valuations of Tesla (valued at $150-200 range in 2019-2020), Apple, and other companies have been well-documented, sometimes prescient, sometimes early. He openly discusses his mistakes (he admits he sold Tesla too early). His value is primarily as a framework provider rather than as a stock picker, though his stock picking has been reasonable.
Extraordinarily transparent — perhaps the most transparent investor/academic in the world. He publishes his entire valuation models as downloadable spreadsheets. He shares his personal portfolio holdings and returns on his blog. He records and posts all his university lectures for free. He writes detailed blog posts explaining his reasoning for every valuation he does. He openly discusses his mistakes and updates his valuations publicly. His blog 'Musings on Markets' is one of the most respected financial blogs. He also maintains comprehensive datasets on market statistics (risk premiums, sector averages, etc.) that he makes freely available.
Impeccable integrity. As an academic, he has no conflicts of interest from managing other people's money. He does not sell subscriptions, investment advice, or charge for his content. All his teaching materials, datasets, and valuations are free. He has consistently refused to become a fund manager or sell his brand for financial gain. He is intellectually honest to a fault — he openly changes his mind when evidence warrants it and admits his errors publicly. He does not engage in self-promotion or sensationalism. His motivations appear to be purely educational and intellectual.
Personal portfolio has historically included: Apple, Tesla (bought and sold based on valuation), Meta/Facebook, Alphabet/Google, various international stocks, and some smaller companies. He tends to hold 15-25 positions. Notably, he valued and bought Tesla early, then sold when his valuation was exceeded. He has valued and discussed NVIDIA, Microsoft, Amazon, and most major tech companies publicly. He does not run a 13F-filing fund, so exact holdings are only known from his voluntary disclosures on his blog.
Extremely high relevance as a thinking partner and framework provider, though not as someone whose portfolio we would clone. Damodaran's valuation frameworks — particularly his approach to narrative-driven DCF, his treatment of uncertainty, and his public datasets — are directly useful for our analysis work. His emphasis on intrinsic value, intellectual honesty, and willingness to value any company regardless of sector aligns well with our approach. However, he is not a concentrated, conviction-driven investor like us — he is more of a diversified individual investor. His views on AI/AGI are somewhat cautious — he has written about AI valuations and tends to be skeptical of extreme valuations, which is useful as a counterbalance. His free valuation datasets (risk premiums, sector stats) ar...
CFA charterholder, joined Markel Corporation in 1990 as Chief Investment Officer and became CEO in 2016 (co-CEO with Richie Whitt initially, sole CEO from 2023). Under his leadership, Markel has evolved from a specialty insurance company into a Berkshire Hathaway-like conglomerate with three pillars: specialty insurance, Markel Ventures (wholly-owned businesses), and an investment portfolio. Built Markel's equity portfolio from essentially nothing to roughly $8-10 billion. Also built Markel Ventures from scratch into a collection of ~20 diverse businesses generating ~$5B in revenue. Considered one of the most thoughtful and patient capital allocators in the insurance industry. Known for his annual shareholder letters and accessible, humble communication style.
Patient, long-term, quality-focused value investing explicitly modeled after Buffett/Berkshire. Gayner has articulated four key investing principles: (1) profitable businesses with good returns on capital, (2) management teams with equal parts talent and integrity, (3) reinvestment dynamics and capital discipline, (4) available at a fair price. Notably, he does not require a 'cheap' price - he is willing to pay fair value for exceptional businesses, which distinguishes him from deep value investors. He views the insurance float and Markel Ventures as structural advantages that provide patient capital with no redemption pressure. Very long holding periods - has held some positions for 20+ years. Low turnover. Focuses on compounders. Strong emphasis on management quality and culture.
Concentrated, long-only, extremely low turnover. Markel's equity portfolio is public via insurance regulatory filings and consists of roughly 80-100 positions, but the top 10-15 comprise the vast majority of value. Largest historical positions include Berkshire Hathaway, Alphabet/Google, Brookfield Asset Management, Deere & Company, Amazon, Disney, Home Depot, and other high-quality blue chips. The portfolio looks like a 'greatest hits' of quality compounders. In addition to the public equity portfolio, Markel Ventures owns ~20 private businesses in areas like construction services, baking equipment, building products, and healthcare. Total invested capital across all three pillars is substantial. Gayner manages both the public portfolio and oversees Markel Ventures acquisitions.
Excellent long-term track record. Markel's equity portfolio has compounded at approximately 10-12% annualized over Gayner's 30+ year tenure, broadly in line with or slightly ahead of the S&P 500. Markel's book value per share has compounded at roughly 12-14% annually over the same period, driven by the combination of underwriting profits, investment returns, and Markel Ventures growth. Markel stock itself has been a strong long-term compounder, rising from ~$10 adjusted in 1990 to ~$1,600+ in 2025 (roughly 17% CAGR including dividends). The track record is remarkable for its consistency and lack of permanent capital impairment, though the equity portfolio alone hasn't dramatically beaten the index. The value creation through the three-pillar model (insurance + investments + ventures) is th...
High. Gayner writes thoughtful annual shareholder letters that explain his philosophy and decisions. Markel holds an annual meeting often compared to Berkshire's, where Gayner answers questions for hours. He speaks regularly at industry conferences and is known for being accessible and humble. The equity portfolio is disclosed through regulatory filings. Markel Ventures businesses are discussed in annual reports. He does not publish specific buy/sell reasoning for individual positions in real-time, but the overall philosophy and framework are extremely well-documented.
Very high. Gayner is widely regarded as one of the most principled executives in the insurance/investment industry. His emphasis on management integrity as an investing criterion reflects his personal values. Markel's corporate culture under his leadership has been praised for ethical behavior and long-term orientation. He has not been involved in any ethical controversies. He personally owns significant Markel stock, aligning his interests with shareholders. His compensation structure at Markel has been reasonable relative to the value created. Multiple institutional investors and industry peers have publicly praised his character.
Berkshire Hathaway, Alphabet/Google, Brookfield Asset Management, Deere & Company, Amazon, Home Depot, Disney, Diageo, CarMax, Visa. Markel Ventures businesses include Cottrell (car haulers), Eagle Construction, Havco, PartnerMD, and others.
High. Gayner's patient, quality-focused, concentrated approach is closely aligned with our philosophy. His emphasis on downside protection through insurance float (permanent capital, no redemptions) mirrors our desire for little chance of losing money. His four investing principles map well to our framework. The Markel model of insurance + public equities + private businesses is an interesting capital allocation framework to study. His willingness to hold for decades aligns with our long-term horizon. The main limitation is that his portfolio is primarily blue-chip quality stocks that are well-followed, so he's less useful for discovering hidden opportunities. His engagement with technology/AGI themes is limited, though Markel's equity portfolio does include Alphabet and Amazon.
Allan Mecham is one of the most remarkable and unconventional investors of the past two decades. Based in Salt Lake City, Utah, he started Arlington Value Capital in 1999 at approximately age 22 with around $100,000 in capital, with no formal finance education (he dropped out of college), no Wall Street experience, no MBA, and no professional network. Despite this lack of conventional credentials, he compounded capital at extraordinary rates — reportedly generating returns of approximately 400%+ cumulative over his first decade, dramatically outperforming the S&P 500. He managed a concentrated portfolio of typically 5-8 positions, with individual positions sometimes representing 20-40% of the portfolio. At its peak, Arlington Value managed approximately $1 billion in AUM, entirely through ...
Mecham's philosophy is deeply Buffett/Munger-influenced but executed with even greater concentration. Core principles: (1) EXTREME CONCENTRATION — Mecham believed that diversification was protection against ignorance, and that if you truly understood a business, you should bet big. He routinely held 5-8 positions with 20-40% position sizes. (2) CIRCLE OF COMPETENCE — he invested only in businesses he deeply understood, which meant a narrow universe of simple, high-quality businesses. (3) LONG-TERM HOLDING — he held positions for years, with minimal trading. Some positions were held for 5-10+ years. (4) FOCUS ON DOWNSIDE PROTECTION — Mecham cared deeply about not losing money. He looked for businesses with strong balance sheets, durable competitive advantages, and manageable risks. He was w...
Extremely concentrated. Arlington Value typically held only 5-8 positions, making it one of the most concentrated funds in the industry. Position sizes of 20-40% were common. The portfolio was almost entirely US-focused, with holdings in large-cap and mid-cap companies with durable business models. Notable long-term positions included Berkshire Hathaway (consistently one of the largest positions — Mecham viewed it as a permanent holding and deeply understood the Buffett/Munger approach from studying it for years), along with various consumer staples, financial, and industrial companies. The portfolio had very low turnover — positions were held for years. Mecham held significant cash positions (sometimes 20-30%+) when he couldn't find attractive opportunities, demonstrating genuine discipli...
Outstanding, though difficult to verify precisely due to private fund structure. Arlington Value reportedly compounded at approximately 20-25% annualized returns over its roughly 20-year operating history, dramatically outperforming the S&P 500 which returned approximately 6-8% annualized over the same period. Cumulative returns were reportedly 400-500%+ vs approximately 100-150% for the S&P 500 over comparable periods. These returns were achieved with a highly concentrated portfolio and significant cash holdings, making the per-invested-dollar returns even more impressive. Importantly, Mecham achieved these returns without leverage, without shorting, and without complex strategies — purely through concentrated equity selection and patience. The fund had drawdowns during market corrections...
Very low public transparency but reportedly high transparency with investors. Mecham gave almost no public interviews (a handful over 20 years), published no books, wrote no blog posts, had no social media presence, and made no conference appearances. His investor letters were reportedly detailed and thoughtful but were private — not published or leaked (unlike Buffett's letters). The fund's 13F filings provided quarterly snapshots of holdings, which were studied by the value investing community as one of the few windows into his thinking. His extreme privacy was unusual in an era of investor-as-celebrity and was seen by admirers as a sign of focus (no time wasted on marketing or self-promotion) and by skeptics as making the track record hard to independently verify. The lack of public inf...
Very high. Multiple signals point to exceptional integrity: (1) He returned capital to investors voluntarily when the fund was performing well — the opposite of fee-extraction behavior. Most fund managers cling to AUM because fees scale with assets; Mecham walked away from management fees on approximately $1 billion. (2) He never marketed the fund — all capital came through performance and word-of-mouth. (3) He charged reasonable fees and reportedly reduced fees as AUM grew, recognizing that managing more money didn't require proportionally more effort. (4) He maintained extreme personal humility — no flashy lifestyle, no self-promotion, no media seeking. (5) He operated far from Wall Street's groupthink, maintaining independent judgment. (6) His decision to invest primarily in Berkshire H...
Berkshire Hathaway was consistently one of Arlington Value's largest positions (often 20-30%+ of the portfolio), reflecting Mecham's deep understanding of and philosophical alignment with Buffett/Munger. Other reported positions over the years included: Enterprise Products Partners, AutoNation, CarMax, Tesco (UK grocer — reportedly a mistake that was eventually sold at a loss, one of the few known errors), and various high-quality consumer and financial businesses. The common thread was simple, understandable businesses with durable competitive advantages, strong balance sheets, and competent management — classic Buffett-style picks executed with even greater concentration. The Berkshire position was notable because it showed Mecham was comfortable effectively outsourcing capital allocatio...
Very high relevance. Mecham's approach is among the most closely aligned with our philosophy of any investor in this analysis: (1) Extreme concentration (5-8 positions) matches our preference for few, high-conviction bets. (2) Focus on downside protection and not losing money aligns directly with our floor-price methodology. (3) Long-term holding periods (5-10+ years) match our investment horizon. (4) No leverage, no shorting, long-only is exactly our approach. (5) Willingness to hold cash when opportunities are scarce shows genuine discipline. (6) Simplicity and circle of competence over complexity. (7) His Berkshire Hathaway holding demonstrates the same kind of thinking we do — finding a vehicle that compounds value with minimal risk of permanent loss. LIMITATIONS: (1) Mecham is no long...
Bill Nygren is a portfolio manager and CIO at Harris Associates, the Chicago-based investment adviser to the Oakmark family of mutual funds. He has managed the Oakmark Fund (large-cap value) since 2000 and co-manages the Oakmark Select Fund (concentrated large-cap value, ~20 holdings) since 1996. He joined Harris Associates in 1983 as an analyst right out of the University of Wisconsin-Madison, where he earned his BS in accounting and an MS in Finance. He became a CFA charterholder and has spent his entire 40+ year career at the firm, rising from analyst to CIO. He is one of the most respected value fund managers in the US mutual fund industry. Oakmark Funds (Harris Associates) manages approximately $90-100 billion in total AUM across multiple strategies. Nygren is known for his distinctiv...
Nygren's philosophy is a blend of value investing and growth investing -- GARP (Growth at a Reasonable Price) done well. He looks for companies trading at a significant discount to his estimate of intrinsic value, but critically, he insists that intrinsic value per share must be growing over time. He believes the best value investments are businesses whose per-share value grows at above-average rates, purchased at a discount to that growing value. His key criteria: (1) stock trades at a significant discount to intrinsic value (typically 60-70 cents on the dollar); (2) management team that thinks like owners and allocates capital well (share buybacks at discounts, smart M&A, good operating decisions); (3) the company's intrinsic value per share is growing -- this is his key differentiator f...
The Oakmark Fund holds approximately 50-60 positions, which is moderately concentrated for a large mutual fund. However, the Oakmark Select Fund -- Nygren's concentrated vehicle -- holds only 18-22 positions, making it highly concentrated. The top 10 positions in Select typically represent 60-70% of the portfolio. Sector allocation has shifted meaningfully over the years: Nygren was early to recognize that technology companies could be value investments, and his portfolio has increasingly included names like Alphabet, Meta, Amazon, and other tech giants alongside traditional value holdings in financials, industrials, and consumer companies. Average holding period is 3-5 years. Portfolio turnover is relatively low for an active manager (~20-30% annually). He runs long-only, no leverage, no ...
Strong long-term track record. The Oakmark Select Fund (concentrated) has returned approximately 11-12% annualized since inception in 1996, beating the S&P 500 over most long-term measurement periods. The Oakmark Fund has returned approximately 11-12% annualized since Nygren took over in 2000, also outperforming its benchmark. Nygren won Morningstar's Domestic Equity Fund Manager of the Year in 2001. He has shown particular skill during periods of market stress -- he was heavily concentrated in technology and financials during periods when they were out of favor, and his patience was rewarded. He suffered significant underperformance in 2007-2009 (financial crisis) due to heavy exposure to financial stocks (Washington Mutual was a notable loss), but recovered strongly afterward. The 2020-2...
High transparency. As a registered mutual fund manager, Oakmark files quarterly holdings disclosures and publishes semi-annual and annual reports. Beyond regulatory requirements, Nygren writes detailed quarterly commentaries explaining his investment rationale, discussing new purchases and sales, and sharing his views on valuation methodology. These commentaries are publicly available on the Oakmark website and are considered among the best investor letters in the mutual fund industry. He frequently appears at investment conferences, gives media interviews, and has published articles explaining his 'growing value' philosophy. Fee structure is transparent and reasonable for active management (expense ratio ~0.88% for Oakmark Fund, ~0.97% for Oakmark Select). He is open about mistakes and le...
High integrity. Nygren has spent his entire career at one firm (Harris Associates, 40+ years), demonstrating loyalty and consistency. He invests heavily in his own funds -- Harris Associates employees collectively have significant personal capital in the Oakmark funds. He has been consistent in his investment philosophy through multiple market cycles, even when his style was out of favor (2017-2019 growth dominance, 2007-2009 financial crisis). The Washington Mutual loss in 2008 was painful, but Nygren was transparent about the mistake and what he learned from it. He has not been involved in any ethical scandals, fraud, or regulatory issues. He advocates for shareholder-friendly management practices and aligns himself with companies that return capital to shareholders through buybacks and ...
Recent top holdings include Alphabet (Google), Meta Platforms, Amazon, Capital One Financial, Corebridge Financial, Charter Communications, General Motors, APA Corporation, Ally Financial, EOG Resources, and various financial companies. Nygren has notably been willing to own Big Tech names within a value framework -- he was early to recognize that Alphabet trading at 15x earnings was a 'value stock' despite its growth profile. Historical notable positions include eBay, Apple (bought early in his value framework), Bank of America, and various financial sector names. The portfolio typically has meaningful exposure to financials (25-30%), technology (20-30%), and communication services (10-15%).
Bill Nygren is highly relevant to our approach. His 'growing value' philosophy -- buying businesses at a discount to intrinsic value where that intrinsic value is itself growing -- is very well aligned with our focus on 'fundamentally great companies with secular tailwinds' bought at reasonable or discounted prices. His concentrated vehicle (Oakmark Select) matches our preference for few, high-conviction positions. His long-only, no-leverage structure matches ours. His willingness to own technology companies within a value framework aligns with our AGI thesis -- if Meta or Alphabet is an AGI beneficiary trading at a discount, Nygren would own it (and does). His focus on management quality and capital allocation aligns with our management assessment framework. His weaknesses relative to our...
Martin J. Whitman (1924-2018) was one of the most original thinkers in value investing. Born in the Bronx, New York, he served in the U.S. Navy during World War II, then earned degrees from Syracuse University. He had a long and varied career before founding Third Avenue Management in 1986 at age 62 — an unusually late start for a fund manager who would go on to build a legendary franchise. Before Third Avenue, he worked as a securities analyst, managed distressed-debt portfolios, served as a corporate advisor, and taught value investing at Yale School of Management for over two decades. His academic appointment was notable because he was a practitioner-professor who taught from real-world experience rather than financial theory. He was deeply skeptical of academic finance, particularly Mo...
Whitman's philosophy was distinctive and intellectually rigorous — arguably the most academically grounded among pure value investors. His key principles: (1) DISTINCTION BETWEEN 'SAFE AND CHEAP' — he insisted that a stock could be cheap without being safe (a value trap) or safe without being cheap (no return potential). True value investing required finding securities that were BOTH safe AND cheap. (2) PRIMACY OF THE BALANCE SHEET — Whitman believed that Wall Street's obsession with earnings and P/E ratios was deeply misguided. He focused instead on Net Asset Value (NAV), particularly tangible book value, and what he called 'wealth creation' — the ability of a company to generate resources that strengthened the balance sheet over time. (3) CREDIT ANALYSIS APPLIED TO EQUITIES — drawing on ...
Concentrated, long-term, asset-focused equity portfolio. Third Avenue Value Fund typically held 25-40 positions with significant concentration in top holdings (top 10 positions often represented 40-60% of the fund). Holding periods were measured in years — Whitman was a true long-term holder who would patiently wait for the market to recognize the underlying asset value. Sector allocation was driven entirely by bottom-up stock selection rather than macro views. He had significant exposure to real estate (land, property companies), conglomerates (holding companies trading at discounts to NAV), and financial companies (banks, insurance companies where balance sheet analysis was critical). International diversification was meaningful — he invested in Asian and European companies when they off...
Excellent long-term record with notable late-career difficulties. From 1990 to approximately 2007, Third Avenue Value Fund delivered outstanding returns, significantly outperforming the S&P 500 over most rolling periods. The fund's NAV-focused, asset-heavy approach performed exceptionally well during periods when value investing was in favor. However, the 2008 financial crisis exposed vulnerabilities: (1) The Third Avenue Value Fund suffered significant losses (~40%+ drawdown) because many balance-sheet-heavy holdings (financials, real estate, conglomerates) were precisely the sectors most impacted by the credit crisis. (2) More damaging to Whitman's legacy, the Third Avenue Focused Credit Fund (a separate distressed-debt fund managed by different PMs) famously gated investor redemptions a...
High. Whitman was exceptionally transparent. His quarterly shareholder letters for Third Avenue Value Fund are legendary in the investment community — they were essentially mini-textbooks on value investing, explaining his reasoning for each major position in detail, discussing broader valuation frameworks, and critiquing conventional Wall Street wisdom. These letters ran for decades and are still studied by value investors. His books further elaborated his framework with real-world examples. He taught at Yale for over 20 years, openly sharing his methodology. He was willing to explain why he was wrong and what he learned from mistakes. The Focused Credit Fund gating was a significant transparency failure, but it was not under his direct management. His own shareholder letters remain among...
High. Whitman was a genuine intellectual who invested based on deep analysis rather than marketing or trend-following. He was consistent in his approach over decades, never style-drifting to chase performance (unlike many value managers who quietly shifted toward growth during the late 2010s). He was transparent about his mistakes and willing to explain his reasoning even when positions were losing money. He lived modestly relative to his wealth. His Yale teaching demonstrated a genuine commitment to educating the next generation rather than just extracting fees. His fee structure was reasonable for an active mutual fund. The Focused Credit Fund failure is a legitimate black mark, but Whitman's personal integrity was widely respected across the investment community. He was known as a strai...
Over his career, Whitman held positions in: Forest City Realty Trust (real estate), Brookfield Asset Management (asset-heavy conglomerate), Bank of New York Mellon, various Asian holding companies (Wheelock, Cheung Kong/CK Hutchison), Investor AB (Swedish holding company), Toyota Industries, various financial companies and real estate developers. His portfolio was characterized by companies with substantial tangible assets, strong balance sheets, competent management, and stock prices trading below estimated NAV. He also invested in distressed and restructuring situations where his credit-analysis skills gave him an analytical edge.
High relevance. Whitman's approach is deeply aligned with our philosophy in several key areas: (1) His 'safe AND cheap' framework maps directly to our floor-price methodology — he insisted on both downside protection AND return potential. (2) His balance-sheet focus and emphasis on tangible assets aligns with our floor-price computation approach (scrutinizing every balance sheet line item, questioning goodwill/intangibles). (3) His distinction between safe and cheap prevents the trap of buying statistically cheap stocks that are fundamentally broken. (4) His credit-analysis approach to equities (can the company survive?) is exactly how we think about floor prices. (5) His concentrated, long-term holding style matches our approach. (6) His willingness to invest in complex, hard-to-analyze s...
Born 1961. Worked at W.R. Grace and then at Quad-C Management (a private equity firm) before founding Peninsula Capital Advisors in 1999. Ran Peninsula until joining Berkshire Hathaway in 2012 as one of Buffett's two portfolio managers (alongside Todd Combs). Famous for growing his IRA from ~$70,000 in 1989 to over $264 million by 2012 -- a ~30% annualized return over 23 years, entirely within a tax-advantaged account. Won two charity lunch auctions with Buffett (2010, 2011) for ~$5.25M total, which led to his hiring. Manages roughly $15-20B of Berkshire's equity portfolio.
Value-oriented with a quality bias. Focuses on businesses with durable competitive advantages, strong management, and attractive valuations. More willing than Buffett to invest in technology and healthcare. Known for deep due diligence -- will spend months researching a single company. Patient capital deployer with multi-year holding periods. Has described his approach as finding businesses where the downside is limited and the upside is substantial. Influenced by Buffett and Munger but has his own distinct style, leaning slightly more growth-oriented.
Moderately concentrated. Manages a portion of Berkshire's portfolio with positions typically in the $1-5B range. Known positions attributed to him include DaVita, Liberty Broadband/Liberty Media, Charter Communications, and more recently some tech-adjacent names. Willing to hold positions for many years. His personal IRA track record suggests even more concentrated personal investing. At Berkshire, somewhat constrained by the size of capital ($15-20B) but still runs a focused book.
Outstanding. The IRA track record (70K to $264M+ over 23 years) is one of the most remarkable documented individual investment records. At Berkshire, performance attribution is harder since individual picks are not publicly separated from Buffett's and Combs'. Peninsula Capital reportedly generated strong returns (~1,236% cumulative vs 146% for S&P 500 from 2000-2011). Some reports suggest his Berkshire portfolio has underperformed the S&P 500 in recent years, but this is difficult to confirm given lack of public attribution.
Low-moderate. No public letters or interviews. His positions are embedded in Berkshire's 13F, making attribution difficult. Occasionally mentioned in Berkshire annual meeting Q&A. The IRA story is well-documented. Does not seek publicity. Buffett has praised him publicly but Weschler himself is very private.
Very high. Buffett's willingness to entrust him with tens of billions is a strong endorsement. No scandals or controversies. The charity auction approach to meeting Buffett (paying $5.25M for two lunches) shows both confidence and willingness to put money where conviction is. Known as deeply honest and straightforward.
DaVita (kidney dialysis -- long-term Berkshire position often attributed to Weschler), Liberty Broadband, Liberty Media, Charter Communications. Some healthcare and fintech positions. Exact attribution within Berkshire's $300B+ equity portfolio is speculative.
High. His philosophy -- limited downside, substantial upside, deep research, long holding periods -- aligns well with ours. The IRA track record demonstrates what concentrated, patient value investing can achieve over decades. His willingness to look at healthcare and technology expands the idea set. Main limitation: very low transparency since his picks are buried in Berkshire's 13F, making it hard to follow in real-time.
Christopher 'Chris' Davis is Chairman and Portfolio Manager of Davis Advisors, a New York-based investment firm founded by his father Shelby M.C. Davis in 1969. He is a third-generation investor: his grandfather, Shelby Cullom Davis, turned a $100,000 investment in insurance stocks in 1947 into $800+ million by the time of his death in 1994 -- one of the greatest individual investment track records in history. His father Shelby M.C. Davis founded Davis Advisors and built it into a major value-oriented fund family. Chris joined the firm in 1989 after working as an analyst at a brokerage firm, and became lead portfolio manager of the flagship Davis New York Venture Fund (now Davis Opportunity Fund) in 1995. He has managed the fund for approximately 30 years. Davis Advisors manages approximat...
Davis's philosophy centers on what he calls an 'owner-operator mentality' -- analyzing businesses as though he were buying the entire company. His key principles: (1) Focus on durable, well-managed businesses that can compound intrinsic value at above-average rates over long periods (compounders); (2) Pay a reasonable price -- he is willing to pay fair valuations for exceptional businesses rather than insisting on deep discounts for mediocre ones; (3) Alignment of interests -- he strongly emphasizes investing alongside management teams who think and act like owners, not hired managers; (4) Financial strength -- he prefers companies with strong balance sheets, particularly in the financial sector where leverage amplifies both good and bad outcomes; (5) Multi-generational thinking -- his tim...
The Davis New York Venture Fund / Davis Opportunity Fund holds approximately 40-60 positions, making it moderately concentrated by mutual fund standards. The top 10 positions typically represent 40-50% of assets. Davis also runs a more concentrated strategy (Davis Select Advisers) for institutional and high-net-worth clients. Sector allocation has historically been heavily weighted toward financials (30-40% at times), reflecting the family's expertise and conviction in well-run financial institutions. More recently, technology exposure has increased significantly (20-30%), with Meta, Alphabet, Amazon, and Applied Materials as major positions. He is long-only, no leverage, no shorting. Holding periods are very long -- some positions have been held for 10-20+ years. Turnover is low (typicall...
Davis New York Venture Fund has a mixed but overall solid long-term track record. Under Chris Davis's management since 1995, the fund has returned approximately 9-10% annualized through 2025, which is roughly in line with or slightly below the S&P 500 over the same period. However, the track record is uneven: the fund dramatically outperformed during 1995-2007, then was hit hard during the 2008-2009 financial crisis due to heavy exposure to financial stocks (AIG, Merrill Lynch, Wachovia were all holdings that suffered devastating losses). The financial crisis was a defining moment -- losses in financials were severe and avoidable in hindsight. Davis has been transparent about these mistakes and adjusted his approach (more diversification, better risk management within financials). The 2010...
High transparency. As a mutual fund manager, Davis files regular holdings disclosures, publishes semi-annual and annual reports, and maintains a public website with investment philosophy materials. Chris Davis writes periodic shareholder letters and commentaries that are thoughtful and educational, though less frequent and detailed than some peers (like Nygren's quarterly letters). He is accessible through media appearances, conference presentations, and the Davis Advisors website. The firm publishes its 'Investor's Checklist' and various educational materials about their investment process. Fee structure is transparent and standard for active management (expense ratios ~0.90-1.00%). The $2+ billion family investment is publicly disclosed and provides unique credibility. He is open about p...
Very high integrity. The Davis family's $2+ billion co-investment in their own funds is the single strongest alignment signal in the mutual fund industry -- they have more money at risk alongside shareholders than virtually any other fund family. Chris Davis has been managing money for 30+ years without any ethical scandal, fraud, or regulatory issue. He serves on the board of Berkshire Hathaway, which reflects the highest endorsement of character in the value investing community. His compensation structure aligns with long-term fund performance. He is intellectually honest about mistakes (financial crisis losses) and has demonstrated genuine learning and adaptation. He emphasizes the importance of trust, long-term relationships, and treating fund shareholders as partners. The multi-genera...
Recent major holdings include Meta Platforms, Berkshire Hathaway, Capital One Financial, Amazon, Applied Materials, US Bancorp, Bank of New York Mellon, Alphabet, JPMorgan Chase, Wells Fargo, Markel Corporation, New Oriental Education, and Vitalik (a Brazilian financial company). The portfolio reflects a blend of high-quality financials (the family specialty) and increasingly, large-cap technology companies that Davis views as durable compounders at reasonable valuations. Historical notable positions include AIG (pre-crisis, painful loss), American Express, Costco, and various insurance companies.
Chris Davis is highly relevant to our approach. His 'owner mentality' and focus on durable compounders at reasonable prices aligns with our philosophy. His concentration level in the select strategy is compatible with our ideal. His genuinely multi-decade time horizon exceeds even our 5-10 year target. His massive personal co-investment ($2B+) demonstrates the ultimate skin in the game. His Berkshire Hathaway board seat confirms his standing in the value investing community. His emphasis on financial strength and balance sheet quality supports our floor price approach. Key gaps: (1) his portfolio is more diversified than our ideal in the mutual fund structure (40-60 positions); (2) his heavy financial sector concentration has led to painful losses (2008) -- financials are complex, leverage...
Sir John Marks Templeton (1912-2008) was one of the greatest investors of the 20th century. Born in Winchester, Tennessee, he graduated from Yale University in 1934 at the top of his class and attended Oxford as a Rhodes Scholar. He started his investment career in 1937 during the Great Depression. In 1939, at the outbreak of World War II, he famously bought 100 shares each of every company on the New York Stock Exchange trading below $1 per share — 104 companies total, investing about $10,400. He profited on 100 of the 104 positions, quadrupling his money within four years. He founded Templeton Growth Fund in 1954, which he managed until 1992. A $10,000 investment in the fund at inception would have grown to approximately $2 million by the time he sold the Templeton funds to Franklin Reso...
Templeton was a pioneering global contrarian value investor. His core principles: (1) 'Buy at the point of maximum pessimism' — his most famous investing dictum. He actively sought markets and companies that were most out of favor, depressed, and overlooked. (2) Global diversification before it was common — he was one of the first American investors to look beyond US borders, investing in Japan in the 1960s when most Americans wouldn't consider it, and in other international markets decades before globalization. (3) Value orientation — he sought to buy companies at a fraction of their intrinsic value, focusing on low P/E ratios, price-to-book value, and other value metrics. (4) Long-term horizon — holding periods of 5+ years were standard. He said 'The time of maximum pessimism is the best...
Templeton managed a diversified global portfolio, typically holding 100-200+ positions across many countries. The Templeton Growth Fund was one of the first truly global equity funds. He was a pioneer in investing in Japan (1960s-1970s), Korea, and other Asian markets before most Western investors. His approach was to identify the most undervalued markets in the world and build positions there. He was willing to invest in countries experiencing crisis, war, or political turmoil if valuations were low enough. Geographic allocation was purely a function of where the best values were. He ran relatively low turnover, holding positions for years. The fund was benchmarked against global indices but managed with a value discipline that led to significant tracking error.
One of the greatest long-term track records in investment history. The Templeton Growth Fund returned approximately 15.8% annualized from 1954 to 1992, versus approximately 11.1% for the S&P 500 — nearly 5 percentage points of annual outperformance sustained over 38 years. This turned $10,000 into approximately $2 million. His 1939 'buy everything under $1' trade is legendary. His major country-level calls were often spectacularly successful: buying Japan in the 1960s before its massive bull market, selling Japan in the late 1980s near the peak, buying US stocks during the early 1970s bear market, and identifying value in emerging Asian markets. He sold the Templeton fund family to Franklin Resources in 1992 for $913 million, recognizing that the fund's growing size would make outperforman...
Moderate transparency during his active career. Templeton shared his investment principles broadly through interviews, speeches, and several books. His '16 Rules for Investment Success' and 'Maxims of Sir John Templeton' have been widely published and studied. He was thoughtful and articulate in explaining his philosophy. However, his actual portfolio holdings and real-time decision-making were less transparent than modern standards. His legacy writings and principles are widely available and form a valuable body of investment wisdom. Several books have been written about his approach, including 'Investing the Templeton Way' and 'The Templeton Touch.'
Exceptional integrity. Templeton lived modestly despite his enormous wealth, famously driving old cars and living simply. He donated over $1 billion to charity, primarily through the Templeton Foundation. He was deeply religious and saw his investment success as stewardship rather than personal aggrandizement. He sold his fund company when he believed size would impair performance, prioritizing investor returns over fee income. He was honest about his approach and did not promise unrealistic returns. His renunciation of US citizenship (for tax purposes) is the one area that draws some criticism, though it was legal. He is universally respected in the investment community for his character, discipline, and generosity.
Templeton's most famous investments include: (1) The 1939 'under $1' trade — 104 NYSE stocks. (2) Japanese stocks in the 1960s-1970s before the massive bull market. (3) Various Korean, Taiwanese, and other Asian stocks in the 1970s-1980s. (4) Ford Motor Company during the early 1980s when the auto industry was in crisis. (5) Numerous depressed European stocks during various crises. (6) He famously shorted 84 NASDAQ stocks near the 2000 peak, each within days of their lockup expiration. Since he died in 2008, there are no current holdings to follow.
High relevance as a philosophical and historical model, though no current actionable insights. Templeton's 'buy at maximum pessimism' approach aligns strongly with our value orientation and contrarian instincts. His emphasis on emotional discipline, long-term holding, and humility are directly applicable. His pioneering global perspective expanded the opportunity set beyond domestic markets. His track record demonstrates that deep value investing, rigorously applied over decades, generates extraordinary returns. However: (1) He is deceased (2008), so there are no current portfolio actions to follow. (2) His extreme diversification (100-200+ holdings) is far from our concentrated ideal. (3) He had no framework for technology disruption or AGI. (4) His approach was developed in a pre-interne...
CEO and portfolio manager at Ruane, Cunniff & Goldfarb, the advisory firm for the Sequoia Fund. The fund was originally founded in 1970 by Bill Ruane and Rick Cunniff, colleagues of Warren Buffett. Buffett himself recommended Ruane to investors when he closed his partnership. The Sequoia Fund has one of the longest and most distinguished track records in the mutual fund industry. Poppe took over leadership after navigating the fund through the Valeant Pharmaceuticals debacle (2015-2016) when the fund's massive Valeant position collapsed. Under his leadership, the fund has refocused on its traditional concentrated value approach.
Classic concentrated value investing in the Buffett/Munger tradition. Views shares as ownership stakes in businesses, not trading instruments. Focuses on business quality, competitive advantages, and management competence. Holds positions for years and often decades. The fund's own website states they research businesses 'with the idea of owning them for many years — and often decades.' Non-diversified fund structure allows meaningful concentration. Ignores macroeconomic predictions and market timing. Emphasis on understanding what they own rather than predicting what they cannot control.
Highly concentrated. Typically 20-30 holdings. Top 10 positions represent 60-70% of fund assets. Non-diversified mutual fund structure (explicit in prospectus). Very low turnover — holds positions for years. Historically had enormous single-stock concentration (30%+ in Berkshire Hathaway at times, and the ill-fated 30%+ in Valeant). Post-Valeant, has maintained concentration but with better risk management. Current top holdings include Alphabet, Berkshire Hathaway, Meta, and other quality compounders.
Mixed but long. Since 1970 inception, the Sequoia Fund has generated strong long-term returns, roughly matching or slightly outperforming the S&P 500 over the full period. However, the Valeant disaster in 2015-2016 was a major blemish — the fund lost roughly 25% in a year primarily due to Valeant, which fell from $260 to under $30. This triggered significant outflows, board changes, and a restructuring of the firm. Post-Valeant (2017-present), performance has recovered and the fund has regained credibility. The Valeant episode is a case study in concentration risk and the danger of abandoning core principles.
High. As a registered mutual fund, Sequoia Fund provides regular shareholder letters, full portfolio disclosure, semi-annual reports, and an annual investor meeting. The shareholder letters are well-written and intellectually honest. The fund was transparent about the Valeant mistake. This level of disclosure is among the best in the industry.
Mixed. The fund's Buffett-lineage and long history suggest strong integrity. However, the Valeant episode raised serious questions: the firm's previous leadership concentrated 30%+ in a company that was later revealed to have accounting irregularities and predatory drug pricing. Some critics argue the firm's due diligence failed badly. Post-Valeant leadership under Poppe has restored credibility, but the incident remains a significant mark. The firm handled the crisis transparently, which partially redeems the integrity assessment.
Current: Alphabet, Berkshire Hathaway, Meta Platforms, UnitedHealth Group, Danaher, Charles Schwab, Constellation Software. Historical: massive Valeant position (2010-2016), long-term Berkshire Hathaway position. The current portfolio reflects a return to quality-business-focused investing.
High. Sequoia Fund's philosophy is deeply aligned with ours: concentrated, long-term, business-owner mentality, Buffett/Munger intellectual lineage. Their focus on understanding businesses rather than predicting markets matches our approach. The Valeant episode is a cautionary tale directly relevant to our methodology — it shows what happens when concentration risk meets due diligence failure. Their current portfolio includes companies we analyze (Meta, Alphabet, Berkshire). The fund's transparency through shareholder letters provides genuine analytical value.
Michael Mauboussin is Head of Consilient Research at Counterpoint Global, Morgan Stanley Investment Management. Previously, he was Director of Research at BlueMountain Capital Management, Head of Global Financial Strategies at Credit Suisse, and Chief Investment Strategist at Legg Mason Capital Management (where he worked alongside Bill Miller). He has been an adjunct professor at Columbia Business School for over 30 years, teaching a popular course on the investment process. He graduated from Georgetown University. He is the author of several influential investment books: 'More Than You Know,' 'Think Twice,' 'The Success Equation,' and 'Expectations Investing' (co-authored with Alfred Rappaport). He is widely regarded as one of the most rigorous and intellectually honest thinkers in the i...
Mauboussin's philosophy is deeply rooted in decision-quality over outcome-quality. Key tenets: (1) Expectations investing — the stock price reflects a set of expectations about future performance, and the investor's job is to determine whether those expectations are too high or too low. (2) Base rates and outside view — always start with base rates of performance for similar companies/situations before adjusting for company-specific factors. (3) Skill vs. luck — understanding where your edge comes from and how sustainable it is. (4) Moats and competitive strategy — deep understanding of competitive advantages and their durability through the lens of Michael Porter's framework. (5) Capital allocation — focus on how management deploys capital and the returns they generate. (6) Behavioral edg...
Mauboussin is primarily a researcher and strategist, not a portfolio manager himself. At Counterpoint Global (Morgan Stanley), he leads the Consilient Research team which supports the investment team led by Dennis Lynch. Counterpoint Global manages approximately $100-150 billion in assets across several strategies that tend to be growth-oriented with a long-term quality focus. The portfolio team (Dennis Lynch's group) runs concentrated strategies with high-conviction, long-term holdings in quality growth businesses. Mauboussin's research directly influences their investment decisions but he does not personally manage money. His research papers are widely read across the industry.
Counterpoint Global under Dennis Lynch (which Mauboussin supports) has had an exceptional track record, particularly in the 2015-2021 period, with its flagship Growth Fund significantly outperforming the S&P 500. The fund has had more mixed results in 2022-2023 as growth stocks corrected. Mauboussin's personal intellectual track record is stellar — his research papers on base rates, ROIC, competitive advantage, and capital allocation have become standard reading in the investment industry. His book 'Expectations Investing' introduced a widely-adopted framework for thinking about stock prices. His influence on the industry is enormous even if his personal P&L is not publicly tracked.
Very transparent in his thinking and frameworks, though not in portfolio-specific ways (since he's not a portfolio manager). He publishes regular research papers that are freely available online, covering topics like ROIC, base rates of corporate performance, capital allocation, and competitive advantage. He gives frequent interviews, podcasts, and conference presentations. His books lay out his thinking in great detail. However, since he's at a large institution (Morgan Stanley), there are limits on what he can say about specific stocks or portfolio positioning.
Impeccable integrity. He is universally respected in the industry as a deeply honest, rigorous thinker who cares about getting things right, not about marketing or self-promotion. He freely shares his research and ideas. He is known for intellectual humility — he changes his mind when evidence warrants it and credits others' work extensively. He has no history of conflicts of interest, misleading claims, or ethical lapses. His long tenure as a Columbia professor alongside his industry role speaks to his commitment to education and intellectual rigor.
Since Mauboussin is a researcher rather than portfolio manager, his personal holdings are not publicly known. Counterpoint Global's holdings (which his research supports) have historically included high-quality growth companies like Shopify, Spotify, Roper Technologies, Gartner, ServiceNow, and various technology and healthcare companies. The team favors companies with strong competitive positions, high returns on invested capital, and long runways for growth.
Extremely high relevance as a thinker and framework provider. Mauboussin's expectations investing framework is directly applicable to our approach — it helps determine what price already reflects and where the market may be wrong. His base rate research is invaluable for calibrating our estimates of future company performance. His work on competitive advantage and ROIC helps assess moat durability. His emphasis on process over outcome and decision quality aligns with our rational, evidence-based approach. However, he is not a concentrated, bottom-up stock picker — he is more of a meta-thinker about investing. His AGI awareness is moderate; he has written about AI's impact on business but not specifically about AGI timelines or transformative AI scenarios.
Born 1939 in the Netherlands during World War II. As an infant, his Jewish parents placed him with a non-Jewish Dutch family to survive the Holocaust — both his parents perished in concentration camps. Emigrated to the United States as a child and grew up in modest circumstances in Los Angeles. Had no formal college education — largely self-taught in investing through voracious reading. Studied the works of Benjamin Graham, Warren Buffett, Philip Fisher, and other investment masters. Founded Century Management in 1974 in Houston, Texas, as a registered investment advisor managing money for high-net-worth individuals and families. Built the firm to approximately $1-2B in AUM through consistent performance and word-of-mouth referrals. Semi-retired in the 2010s, handing day-to-day management ...
Van Den Berg is a classic Graham-Dodd value investor with strong influences from Buffett and Fisher. His core framework: (1) Buy companies trading significantly below intrinsic value, with a large margin of safety. (2) Focus on companies with strong balance sheets, low debt, and high free cash flow generation. (3) Be patient — he is willing to hold cash for extended periods (sometimes 30-50% of the portfolio) when he cannot find sufficiently undervalued securities. (4) Concentrate the equity portion of the portfolio in his best ideas — typically 15-30 positions. (5) Emphasize psychological discipline — Van Den Berg believes that mastering one's own emotions (fear, greed, impatience) is more important than any analytical technique. He has spoken extensively about the role of personal growth...
Moderately concentrated with significant cash allocation. When fully invested in equities, Century Management typically held 15-30 positions, making it one of the more concentrated small advisory firms. However, the overall portfolio often had 20-50% in cash or short-term fixed income when Van Den Berg could not find sufficient bargains. This cash position acted as both a risk buffer and dry powder for buying during market dislocations. He invested across the market cap spectrum but favored mid-cap and smaller companies where institutional coverage was thinner. Sector exposure varied based on where value was available — he was not a sector specialist. The approach was opportunistic and contrarian, buying during periods of maximum pessimism and selling (or trimming) when valuations became r...
Strong long-term track record over 40+ years, though precise publicly available return figures are limited because Century Management is a private advisory firm, not a mutual fund. Based on available interviews and industry recognition, Century Management delivered annualized returns in the low-to-mid teens over multiple decades, meaningfully outperforming the S&P 500 over the full period. Van Den Berg's approach performed particularly well during and after market downturns (2001-2003, 2008-2009) because his large cash holdings allowed him to buy aggressively during panics. His worst relative periods were during extended bull markets when his cash drag hurt performance. He was featured in the Manual of Ideas, invited to speak at various value investing conferences, and recognized by peers ...
Medium. As a private advisory firm, Century Management does not file 13F forms (or did not need to for much of its history given AUM below reporting thresholds). There are no public mutual fund fact sheets. However, Van Den Berg has been reasonably generous with his time in interviews and conference presentations. He has given detailed talks about his investment philosophy, his approach to valuation, and specific case studies. His investor letters to Century Management clients are reportedly excellent — detailed, honest about mistakes, and focused on process. He has shared his reading lists and philosophical influences openly. The lack of public portfolio disclosure is the main limitation, but for those who have access to his letters and presentations, the thinking is quite transparent.
Very high. Van Den Berg's life story — surviving the Holocaust as an infant, self-educating, building a successful investment firm from nothing — speaks to extraordinary character. He has been known for honest, direct communication with clients, admitting mistakes, and prioritizing client interests. He kept his firm deliberately small to maintain quality and avoid the conflicts that come with asset gathering. His fee structure was reasonable and aligned with client interests. He has no SEC sanctions, scandals, or ethical issues. He invested his own capital alongside clients. His emphasis on personal growth and psychological self-mastery is genuine, not marketing — those who know him describe a person of deep integrity and humility. He has been generous with his time in mentoring younger in...
Specific position disclosures are limited due to Century Management's private nature. Based on interviews and presentations, Van Den Berg has favored companies with strong balance sheets in sectors experiencing temporary problems: financials during credit crises, energy during oil price collapses, consumer staples during market dislocations. He has mentioned investments in insurance companies, commodity-related businesses (when commodities were depressed), and asset-heavy companies trading below tangible book value. His approach to holding large cash positions means the specific equity positions he does hold are high-conviction ideas.
High relevance. Van Den Berg's philosophy aligns closely with ours on multiple dimensions: (1) Focus on margin of safety and downside protection ('little chance of losing money'). (2) Willingness to hold cash when no bargains are available — genuine discipline rather than fully-invested bias. (3) Moderately concentrated portfolios in best ideas. (4) Long-term holding periods. (5) Emphasis on independent thinking and doing your own work. (6) Balance sheet focus and asset analysis. (7) Psychological discipline as a competitive advantage. His approach to intrinsic value — focusing on what an acquirer would pay, tangible assets, and free cash flow — mirrors our floor price methodology. The main limitation is that we cannot track his portfolio in real time, so the value is philosophical/educati...
Murray Stahl is the co-founder, Chairman, and Chief Investment Officer of Horizon Kinetics LLC, a New York-based investment management firm with approximately $7-8 billion in assets under management. He holds a BA and MA from Brooklyn College and an MBA from Pace University. Before co-founding Horizon Kinetics in 1994 (with Steven Bregman), Stahl spent 16 years at Bankers Trust Company managing utility and special opportunity funds. He is also the Chairman of FRMO Corporation (OTC: FRMO), a publicly traded holding company that serves as a vehicle for his personal investment ideas and owns a stake in Horizon Kinetics itself. Stahl is known as one of the most original and independent thinkers in the investment world, writing extensively about unconventional topics including royalty business ...
Stahl's philosophy is deeply contrarian, fundamental, and long-term oriented. Key pillars include: (1) Obsessive focus on 'asset-light' business models, particularly royalty companies, where the company owns rights to revenue streams without operating costs or capital expenditure requirements (Texas Pacific Land is the archetype); (2) Skepticism of index investing and passive indexation, arguing it creates systematic mispricings that active managers can exploit; (3) Interest in inflation-protected assets and real assets as hedges against monetary debasement; (4) Early and sustained interest in Bitcoin and cryptocurrency as a monetary technology, viewing it as digital gold and inflation hedge; (5) Focus on businesses with minimal capital requirements and maximum operating leverage; (6) Very...
Concentrated in a distinctive way. Horizon Kinetics manages multiple funds and separately managed accounts, but the core positions are highly concentrated in a few key themes: royalty companies (Texas Pacific Land Corporation is the largest position by far), cryptocurrency exposure (through Grayscale Bitcoin Trust and mining companies), and selected special situations. The portfolio is long-only, unlevered, and held for very long periods. Turnover is extremely low - Stahl has held Texas Pacific Land for over 15 years. The portfolio has sector concentration risk (heavily weighted to real assets, royalties, and crypto) but individual position conviction is high. FRMO Corporation (his personal holding company) gives additional visibility into his highest-conviction ideas. Assets across Horizo...
Strong over long periods, though volatile and difficult to track precisely because Horizon Kinetics manages multiple strategies. The Kinetics Paradigm Fund (one of their flagship mutual funds) has generally outperformed over long periods, particularly in the 2020-2024 period as inflation, real assets, and crypto themes played out. Texas Pacific Land Corporation, their largest holding, has been an extraordinary long-term winner, rising from around $50/share to over $1,200+ as the royalty model generated massive cash flows from Permian Basin oil production on land TPL owns. Stahl was early and right on Bitcoin, allocating to it before it was institutionally acceptable. However, the concentrated nature of the portfolio means returns are lumpy: years when commodity prices and crypto are out of...
High. Stahl is unusually transparent for an asset manager. He publishes extensive quarterly research letters through Horizon Kinetics that are freely available and intellectually rigorous. These letters discuss portfolio positioning, market views, and deep analysis of individual companies. FRMO Corporation files public financial statements and holds annual shareholder meetings where Stahl speaks at length about his views. Horizon Kinetics' 13F filings are publicly available. He regularly presents at investment conferences (MOI Global, etc.) and shares his thinking openly. The intellectual content of his communications is among the highest quality in the investment management industry.
High. Stahl has maintained consistent investment principles over decades without style drift or chasing trends. He eats his own cooking through FRMO Corp, which puts his personal wealth alongside investors. He is intellectually honest, acknowledging when theses take longer to play out or when he has been early. There are no known regulatory issues, lawsuits, or ethical controversies. His fee structure at Horizon Kinetics is reasonable by industry standards. He does not engage in promotional behavior or hype. His primary motivation appears to be intellectual satisfaction from identifying overlooked investments rather than asset gathering or self-promotion.
Texas Pacific Land Corporation (TPL) - largest position by far, held 15+ years, royalty company owning 880,000 acres in Permian Basin. Grayscale Bitcoin Trust (GBTC) / Bitcoin exposure through various vehicles. FRMO Corporation (OTC: FRMO) - his personal holding company. Dream Unlimited Corp - Canadian real estate. Winland Holdings - small industrial company. Various cryptocurrency mining companies. The TPL position is the signature holding and demonstrates his thesis about royalty business models perfectly: TPL collects royalties and easements on land it owns without any capital expenditure, generating enormous free cash flow from Permian Basin oil and gas activity.
Moderate-to-high relevance. Stahl's approach aligns with several of our principles: concentrated, long-term, low-turnover, focused on downside protection through asset quality rather than diversification. His emphasis on royalty business models (minimal capex, maximum cash flow) is intellectually compelling. His thinking about inflation protection and monetary debasement is relevant to our framework. However, his heavy crypto allocation and commodity exposure may not align with our AGI-focused thesis. His portfolio is also heavily tilted toward a single position (TPL), which creates concentration risk we might not want to replicate. His investment letters are worth reading for the quality of thinking, even if we don't follow all his positions.
Born 1938 in Montreal, Canada. Educated at McGill University (BCom, 1960) and obtained his Chartered Accountant designation. Began his investment career in the late 1960s. Founded Peter Cundill & Associates in 1975 and launched the Cundill Value Fund, which he managed for over 30 years. Became one of Canada's most successful and respected value investors. His approach was deeply influenced by Benjamin Graham's 'Security Analysis' and 'The Intelligent Investor' — Cundill was a devout Graham disciple who took the net-current-asset-value (NCAV) approach seriously and applied it globally. He was one of the first value investors to invest internationally and in emerging markets, applying Graham's principles to Japanese net-nets, European deep-value situations, and distressed markets worldwide. ...
Pure Graham deep-value applied globally. Cundill's philosophy can be summarized in a few core principles: (1) Buy stocks trading below net current asset value (NCAV) — the strictest Graham test, where current assets minus all liabilities exceeds the market cap. (2) Focus obsessively on the balance sheet — what are the hard assets worth in a liquidation scenario? (3) Apply this methodology globally — Cundill was among the first to realize that Graham's methods could be applied in Japan, Korea, Europe, and emerging markets where accounting standards and market structures created even deeper mispricings. (4) Be extremely patient and contrarian — buy when others are panicking, hold through uncertainty. (5) Maintain strict discipline on price — never overpay, always demand a margin of safety. (...
Moderately diversified global deep-value. The Cundill Value Fund typically held 30-60 positions across multiple countries and continents. Position sizes varied from 1-5% for typical holdings to occasionally larger positions (5-10%) for highest-conviction ideas. Geographic diversification was a key feature — the fund at various times had significant exposure to Japan, Korea, Europe, Latin America, and North America. The portfolio often looked very different from any benchmark because Cundill invested wherever value was deepest, regardless of geography. He was willing to invest in distressed or out-of-favor markets that most managers avoided. Turnover was moderate — he held positions until they reached fair value, which could take 1-5 years. Cash levels varied based on opportunity — Cundill ...
Excellent. The Cundill Value Fund compounded at approximately 15% annualized from 1974 to 2005 (over 30 years), significantly outperforming both the S&P 500 and the MSCI World Index. Cundill achieved this with lower volatility than the market over full cycles, though the fund experienced drawdowns during periods of global financial stress. Particularly strong performance came from Japanese net-nets in the 1970s-1980s, post-crisis Asian investments in the late 1990s, and various global deep-value situations. He was awarded the Morningstar International Fund Manager of the Year. The fund's performance demonstrated that Graham's deep-value approach, applied globally with discipline, could generate excellent long-term returns. After Cundill stepped back due to illness (late 2000s), the fund tr...
Medium-high. Cundill kept meticulous investment journals that were the basis for 'There's Always Something to Do' — one of the most honest and detailed accounts of a value investor's actual thought process, including mistakes, doubts, and evolution. His investor letters were reportedly thorough and candid. The Cundill Value Fund reported standard mutual fund performance data. However, as a Canadian fund, the detailed holdings were not as readily accessible through US 13F filings. The Peter Cundill Foundation at McGill promotes his approach and makes some of his thinking available. For a deceased investor, his legacy is unusually well-documented thanks to the book and foundation.
Very high. Cundill was known as a deeply principled investor who prioritized his clients' interests. He invested his own capital alongside fund shareholders. His fees were reasonable by industry standards. He maintained discipline through decades of market cycles without style-drifting to chase performance. No scandals, SEC issues, or ethical controversies. His philanthropy — particularly the Peter Cundill Foundation supporting value investing education — reflects genuine commitment to the field. Colleagues and peers consistently describe him as a person of high integrity, intellectual honesty, and genuine humility. He admitted mistakes openly in his journals and used them as learning opportunities.
Cundill's most notable positions reflected his deep-value, global approach: Japanese net-net stocks in the 1970s-1990s (many small industrial companies trading below liquidation value), Korean stocks after the 1997 Asian crisis, European industrials during various recessions, and North American companies in distressed sectors. Specific names from his journals include positions in Japanese banks, Korean utilities, Canadian natural resource companies, and US companies with hidden asset value. He famously loaded up on Japanese equities when they traded at fractions of book value. His portfolio was always a reflection of where the deepest value existed globally at any given time.
Moderate-high relevance. Cundill's philosophy aligns strongly with our 'floor price' and 'little chance of losing money' approach — his focus on buying below net current asset value is essentially computing a liquidation floor price and demanding a margin of safety below it. His balance sheet obsession matches our emphasis on understanding real assets vs. goodwill/intangibles. His global perspective is valuable — when US markets are expensive, looking internationally expands the opportunity set. His discipline in holding cash when bargains are unavailable mirrors our philosophy. The main limitations: (1) he is deceased, so we cannot follow current positions; (2) his pure NCAV approach may miss great companies that don't have heavy tangible assets (many tech companies); (3) his style does n...
Nick Train (born 1958) is a British fund manager and co-founder of Lindsell Train, an investment management firm he established in 2000 with Michael Lindsell. He manages the Lindsell Train UK Equity Fund, the Finsbury Growth & Income Trust (a listed investment trust), and co-manages the Lindsell Train Global Equity Fund. Before founding Lindsell Train, he worked at GT Management and M&G. Train is known as one of the UK's most distinctive and conviction-driven fund managers. His approach is ultra-long-term, extremely concentrated, with very low turnover — he has described his ideal holding period as 'forever.' Lindsell Train manages approximately GBP 15-20 billion in assets. Train has been a consistent performer over long periods, though his concentrated style led to significant underperfor...
Train's philosophy is among the purest 'quality compounding' approaches in the industry: (1) Buy exceptional businesses with durable competitive advantages and hold them essentially forever; (2) Focus on companies with strong brands, high returns on capital, and recurring revenue — he particularly loves consumer brands and financial exchanges; (3) Extremely low portfolio turnover — he may go years without making a new purchase; (4) Valuation is secondary to business quality — he would rather own a great business at a fair price than a mediocre business at a cheap price; (5) Concentration is a feature, not a bug — owning fewer companies means knowing each one deeply; (6) He is heavily influenced by Warren Buffett, Philip Fisher, and the 'coffee can portfolio' concept; (7) He explicitly avoi...
Extremely concentrated and low-turnover. The Finsbury Growth & Income Trust typically holds 20-25 stocks. Top holdings have historically included: Diageo, Unilever, RELX, London Stock Exchange Group, Mondelez, Burberry, Manchester United (a quirky pick reflecting his love of brands), Heineken, Schroders. The portfolio is heavily weighted toward consumer staples, media/information services, and financial infrastructure. Geographic focus is primarily UK and global brands listed in London, though the global fund invests internationally. Turnover is among the lowest in the industry — Train has held some positions for 15+ years. He owns a significant stake in Lindsell Train itself, aligning his interests with investors. The extreme concentration means performance can be volatile in shorter peri...
Long-term track record is strong. The Finsbury Growth & Income Trust has delivered approximately 10-12% annualized returns since Train took over in 2000, significantly outperforming the FTSE All-Share. The Lindsell Train UK Equity Fund has similarly outperformed over long periods. However, 2022-2024 was a difficult period: his quality/growth holdings de-rated sharply as interest rates rose, and several core holdings (Diageo, Burberry, Hargreaves Lansdown) underperformed significantly. The Finsbury Growth & Income Trust underperformed the FTSE All-Share in 2022 and 2023. Train has been candid about this underperformance but has not changed his approach, arguing that his companies' long-term economics remain intact. This willingness to stick with his process during tough periods is either ad...
High transparency for a UK fund manager. Train writes detailed, thoughtful shareholder letters for the Finsbury Growth & Income Trust and Lindsell Train funds. These letters explain his reasoning, discuss mistakes, and provide genuine insight into his thinking — they are among the best-written fund manager communications in the UK. He is candid about underperformance and does not make excuses. Lindsell Train's website provides clear information about holdings and performance. His investment trust structure means holdings are disclosed regularly. He gives media interviews and has appeared on podcasts discussing his philosophy openly.
Very high integrity. Train has a significant personal investment in Lindsell Train and its funds, strongly aligning his interests with clients. He has never engaged in style drift — his approach has been remarkably consistent for over 20 years. Fee structure is reasonable by industry standards. No scandals, regulatory issues, or ethical concerns. He has been honest about the recent period of underperformance. His willingness to stick with his convictions rather than chase performance is evidence of genuine integrity. He is widely respected in the UK investment community as a thoughtful, principled investor.
Core long-term holdings include: Diageo (spirits — held for 20+ years), RELX (information services), London Stock Exchange Group (financial infrastructure), Unilever (consumer goods), Mondelez (snacks), Heineken (beer), Schroders (asset management), Manchester United (sports brand — a controversial but characteristically brand-focused pick), Burberry (luxury), Hargreaves Lansdown (investment platform). The portfolio reflects Train's belief in durable consumer brands and financial infrastructure businesses. He also owns a stake in Lindsell Train itself through his funds, which is a distinctive feature.
Moderate-to-high relevance. Train's philosophy has significant overlap with ours: (1) Extreme long-term orientation (hold forever); (2) Concentrated portfolio of high-conviction positions; (3) Focus on durable competitive advantages and business quality; (4) Patient, low-turnover approach; (5) Willingness to endure periods of underperformance rather than abandon principles. Differences: (1) Train is explicitly a quality/growth investor, not a deep value investor — he de-emphasizes valuation in favor of business quality, while we focus on floor prices and downside protection; (2) He avoids technology stocks, which means he has no framework for thinking about AGI impact; (3) His portfolio is heavily UK-centric and consumer brand-focused; (4) His recent underperformance raises questions about...
Stephen Mandel Jr. (born 1956) founded Lone Pine Capital in 1997 in Greenwich, Connecticut, after working at both Goldman Sachs (as an analyst and consumer sector head) and Tiger Management under Julian Robertson. He graduated from Dartmouth College and Harvard Business School. Lone Pine grew to become one of the most respected Tiger Cub operations, known for concentrated, high-conviction growth investing. Mandel stepped back from day-to-day management in 2019, transitioning the CIO role to a team-based approach led by Kelly Granat and others, though he remains involved as a senior figure. The fund manages approximately $13.6 billion in 13F-reported assets as of Q4 2025, down from peak AUM of ~$30B+. Net worth estimated at $4-5 billion.
Concentrated, long-term, growth-oriented fundamental investing with strong emphasis on business quality. Mandel's approach: (1) High conviction -- extremely concentrated portfolio, top 10 holdings represent 87.1% of the portfolio, (2) Quality growth -- invests in businesses with strong competitive advantages, high returns on capital, and long growth runways, (3) Long-term orientation -- Lone Pine tends to hold positions for multiple years, not months, (4) Fundamental bottom-up -- deep research into business models, management quality, and competitive dynamics, (5) Long-biased but uses shorts -- primarily long with a significant short book for hedging and alpha, (6) Mandel emphasized understanding the 'unit economics' of businesses and the sustainability of growth. The approach is closest t...
Extremely concentrated growth equity portfolio. 32 equity holdings with top 10 representing 87.1% of portfolio -- one of the most concentrated major hedge funds. AUM approximately $13.6B (13F). Primarily technology and growth-oriented, though also invests in consumer and healthcare growth stories. Long-biased with short positions. The extreme concentration (87.1% in top 10 from only 32 total positions) indicates very high conviction and deep research per position. Q4 2025 showed -1.58% return.
Very strong long-term track record. Lone Pine delivered estimated 15-20% annualized returns from 1997 through the mid-2010s, making it one of the top-performing hedge funds of its era. The fund navigated multiple market cycles effectively. However, more recent performance has been mixed: (1) The transition of leadership from Mandel (stepping back in 2019) creates uncertainty about future performance, (2) AUM has declined from $30B+ peak, which could indicate investor redemptions or deliberate downsizing, (3) 2022 was likely a difficult year given the heavy tech growth orientation, though losses were probably less severe than Tiger Global's given more discipline. The post-Mandel era makes the track record less relevant for forward-looking analysis. Q4 2025 showed -1.58%.
Standard hedge fund transparency through 13F filings. The extreme concentration of the portfolio means the 13F filings are actually quite informative -- with only 32 holdings, you can see essentially the entire portfolio. Mandel has given limited public interviews over his career but has shared his investment philosophy in occasional appearances. Lone Pine does not publicly share investor letters. The leadership transition was communicated clearly to investors.
Strong integrity record. No fraud, insider trading, or regulatory scandals in 27+ years of operation. Mandel is known as a thoughtful, principled investor who built a strong culture at Lone Pine. His Goldman Sachs and Tiger Management pedigree instilled professional standards. The orderly leadership transition (rather than a sudden departure) speaks to institutional planning and responsibility. No controversial behavior. Clean record.
As of Q4 2025 (13F), Lone Pine's highly concentrated $13.6B portfolio holds only 32 positions. Historical major holdings have included Meta Platforms (META), Microsoft (MSFT), Amazon (AMZN), Alphabet (GOOG), and other technology/growth leaders. The fund has also historically held positions in consumer companies and select healthcare growth stories. The concentration level means each position represents significant conviction.
High relevance -- the most philosophically aligned investor in this group. Positives: (1) Extreme concentration (87.1% in top 10, only 32 holdings) closely matches our preference for very few, high-conviction investments, (2) Quality growth orientation -- seeking businesses with competitive advantages and sustainable growth -- aligns with our focus on fundamentally great companies, (3) Long-term holding periods align with our 5-10+ year horizon, (4) Strong track record over 20+ years validates the approach, (5) Technology-heavy portfolio gives exposure to AGI-relevant companies. Negatives: (1) Mandel stepped back in 2019, so the current portfolio may not reflect his thinking, (2) Uses short positions unlike our long-only approach, (3) Growth bias means less focus on downside protection/flo...
David Tepper (born 1957) is one of the most successful hedge fund managers in history. Grew up in a middle-class Pittsburgh family, earned MBA from Carnegie Mellon (1982), worked at Goldman Sachs in the high-yield/distressed debt group under Michael Mortara. Left Goldman after being passed over for partner and founded Appaloosa Management in 1993 with $57M. Built it into one of the most profitable hedge funds ever, with personal net worth estimated at $20B+ as of 2025, making him one of the wealthiest hedge fund managers alive. Owns the Carolina Panthers NFL team (bought 2018 for $2.3B). Converted Appaloosa to a family office in 2019, returning outside capital. Known for his aggressive, contrarian style and willingness to make massive concentrated bets at moments of maximum fear.
Tepper is a contrarian macro investor who specializes in buying assets at moments of extreme distress and pessimism. His core philosophy: 'The key to investing is not to predict the future, but to figure out what's priced in and bet when the odds are heavily in your favor.' He looks for situations where the market is pricing in catastrophe but where the probability of that catastrophe is much lower than the market implies. Famous for his 'probability-weighted outcome' framework — he doesn't just look at upside/downside but weights them by probability. Comfortable making massive concentrated bets (e.g., putting 25-30% of his fund into bank stocks in early 2009). Not a buy-and-hold investor — will trade actively around positions. Also does event-driven, merger arbitrage, and macro plays. Use...
Moderately concentrated (typically 15-25 public equity positions visible in 13F), but with significant credit and macro overlays not visible in equity filings. Willing to concentrate heavily when conviction is high. Recent 13F filings show a strong tilt toward large-cap technology stocks — Alphabet, Amazon, Meta, Microsoft, Nvidia, and Alibaba have been among top holdings in 2024-2025. Also holds energy, financial, and Chinese tech names. Has been notably bullish on AI/technology in recent years, calling it a generational investment theme. Portfolio turnover is moderate — he trades but also holds core positions for multiple quarters.
Exceptional. Appaloosa returned approximately 25-30% annualized from 1993-2019, making it one of the best-performing hedge funds of all time. Key trades: (1) Made $7B in 2009 by loading up on bank stocks and distressed financial debt when markets feared nationalization — Tepper bought Bank of America, Citigroup, and AIG at rock-bottom prices and rode the recovery. This was one of the greatest single-year returns in hedge fund history. (2) Made billions in 2001 buying Enron and WorldCom debt at 20 cents on the dollar. (3) Earned 42% in 2013 on a bet that the Fed would keep rates low. (4) Strong performance in 2023-2024 driven by large technology positions (Nvidia, Meta, Alphabet). Personal wealth grew from $57M (1993) to $20B+ (2025), confirming the durability of his returns.
Moderate. Appaloosa filed 13F reports when managing outside capital, providing visibility into public equity positions. Since converting to a family office in 2019, 13F filings continue but represent only his personal capital. Tepper gives occasional interviews and speaks at conferences (e.g., CNBC, Ira Sohn) where he shares his macro views and sometimes specific positions. He is relatively candid about his investment philosophy and thought process. However, credit positions, shorts, and macro trades are not visible in public filings, meaning the 13F shows only a partial picture.
Good. Tepper has a reputation for being straightforward and honest, if blunt. He returned outside capital in 2019, which is a positive signal — he didn't continue extracting management fees when he didn't need to. Major philanthropy including $67M to Carnegie Mellon (business school renamed in his honor), significant gifts to education and community causes. No major scandals, SEC enforcement actions, or fraud allegations. The one criticism is that Appaloosa's fee structure was aggressive (typical 2/20 or higher), but performance justified it. His purchase of the Carolina Panthers was clean. He has been open about his mistakes (e.g., losing money on certain trades) and doesn't present himself as infallible.
Recent 13F (2024-2025): Alphabet (GOOGL), Amazon (AMZN), Meta (META), Microsoft (MSFT), Nvidia (NVDA), Alibaba (BABA), Uber (UBER), Vistra Energy (VST), energy names. Historical: Bank of America, Citigroup, AIG (2009 crisis trade), various distressed debt positions, airline stocks. Has been a significant buyer of AI-related technology stocks since 2023.
Moderate-high relevance. Tepper's probability-weighted outcome framework resonates with our 'floor price' philosophy — both seek situations where the downside is limited relative to the upside. His willingness to buy when others panic is directly analogous to our approach of buying at the 'very safe price.' His recent heavy positioning in AI/technology stocks (Meta, Nvidia, Alphabet) shows awareness of the AI/AGI theme that is central to our thesis. Key differences: Tepper trades more actively than we would, uses credit and macro instruments we don't, and has a shorter average holding period. He is also a macro thinker rather than a pure bottom-up business analyst. But his general framework of 'what's priced in vs. what's likely' is highly compatible with our floor price methodology. His 1...
Francisco Garcia Parames (born 1963) is a Spanish value investor widely considered the 'Warren Buffett of Spain' and one of Europe's most accomplished deep value investors. He managed Bestinver, Spain's largest independent asset manager, from 1993 to 2014, delivering approximately 15-16% annualized returns over 21 years — one of the best track records in European fund management. He left Bestinver in 2014 after a dispute with the Acciona family (Bestinver's owners) and founded Cobas Asset Management in 2017, raising over EUR 1.5 billion at launch based on his reputation alone. He authored 'Investing for the Long Term' ('Invirtiendo a Largo Plazo'), a well-regarded book on value investing. Parames is deeply influenced by Benjamin Graham, Warren Buffett, and the Austrian school of economics....
Parames is a deep value investor in the classic Graham-Buffett tradition, with a European focus: (1) Buy companies trading at significant discounts to intrinsic value (30-40% margin of safety); (2) Intrinsic value is calculated primarily through normalized earnings, replacement cost of assets, and sum-of-parts analysis; (3) Contrarian — willing to invest in deeply out-of-favor sectors and geographies (energy, shipping, commodities, Southern European companies); (4) Long-term holding horizon — typically 3-5 years for value to be realized; (5) Influenced by Austrian economics — skeptical of government intervention, monetary policy, and fiat currency; (6) Focus on tangible assets and real-world businesses over technology and intangibles; (7) International diversification — invests across Euro...
Moderately concentrated. Cobas funds typically hold 30-50 positions, with the top 10 representing 40-50% of the portfolio. Geographic focus is primarily European, with significant exposure to international companies. Sector preferences skew heavily toward tangible-asset businesses: energy (oil and gas, shipping, commodities), industrials, financials (European banks and insurers), and consumer businesses. He explicitly avoids or underweights technology, which has been a significant performance headwind in recent years. The Cobas Internacional fund is his flagship, investing globally excluding Spain/Portugal. Cobas Seleccion is the combined Iberian + international fund. Turnover is moderate — he holds positions for years but will sell when intrinsic value is reached.
Bestinver period (1993-2014): Exceptional. Approximately 15-16% annualized returns over 21 years, significantly outperforming European indices. He navigated the Asian crisis, dot-com bust, and 2008 crisis successfully. The Bestinver Internacional fund was one of the best-performing European equity funds over this period. He was particularly effective during the European sovereign debt crisis of 2011-2012, buying Southern European companies at distressed valuations. Cobas period (2017-present): Disappointing so far. The funds launched at a difficult time for deep value investing. 2018-2020 was brutal — the international fund lost approximately 40-50% from launch to the COVID low in March 2020, as value stocks were crushed globally. The portfolio recovered significantly in 2021-2023 as energ...
High transparency. Parames publishes detailed quarterly letters explaining his positioning, individual stock theses, and portfolio changes. Cobas provides clear factsheets with full top holdings disclosed. His book 'Investing for the Long Term' is remarkably transparent about his process, mistakes, and thinking. He gives regular interviews and presentations at value investing conferences (notably the Spanish value investing community around Cobas/Bestinver). He is candid about the difficult Cobas performance and has not tried to hide or spin the underperformance. His investor letters are thoughtful and substantive, comparable in quality to the best US value investor letters.
High integrity. Parames has a very significant personal investment in Cobas funds — he has stated publicly that essentially all of his liquid net worth is invested alongside his clients. This is the strongest possible alignment of interests. He left Bestinver on principle (disagreement with owners over business direction) rather than compromise his investment approach. His fee structure at Cobas includes a performance fee, but the base fee is reasonable by European standards. No scandals, regulatory issues, or ethical concerns throughout his 30+ year career. He has been honest about Cobas's disappointing performance. His Austrian economics influence gives him a philosophical framework that values honest money and property rights. He is widely respected in the European value investing commu...
Cobas holdings typically include: Golar LNG (LNG shipping/infrastructure), Aryzta (baked goods company — a turnaround play), Teva Pharmaceutical (generic drugs at distressed valuation), CIR/COFIDE (Italian conglomerate holding company), Babcock International (UK defense/engineering), Renault (French automaker at deep discount), International Seaways (tanker shipping), Elecnor (Spanish engineering/renewables), Semapa (Portuguese conglomerate). The portfolio is distinctly 'old economy' — shipping, energy, industrials, European conglomerates trading at discounts to NAV. Very little technology exposure. These are classic deep value positions: out-of-favor companies in unfashionable sectors with tangible assets providing downside protection.
High relevance — probably the most relevant investor in this group to our philosophy. Key alignment: (1) Deep value with margin of safety — his 30-40% discount requirement mirrors our floor price methodology; (2) Focus on tangible assets and downside protection — very similar to our emphasis on 'little chance of losing money'; (3) Contrarian, willing to be uncomfortable and out of consensus; (4) Long-term holding horizon; (5) Personal capital invested alongside clients — strong alignment; (6) Thoughtful, transparent investor letters worth reading; (7) His book is directly relevant to our approach. Key differences: (1) His technology avoidance is a significant gap — in an AGI world, ignoring technology is potentially dangerous; (2) His Austrian economics framework, while intellectually inte...
Prem Watsa is the founder, Chairman, and CEO of Fairfax Financial Holdings, a Canadian financial holding company based in Toronto. Born in 1950 in Hyderabad, India, Watsa moved to Canada in 1972 with $8 in his pocket. He earned an MBA from the Richard Ivey School of Business at Western University. He began his career at Confederation Life and then managed the investment portfolio at Markel Financial (not related to Markel Corporation). In 1985, he acquired a controlling stake in a small Canadian trucking insurer called Markel Financial, which he renamed Fairfax Financial Holdings (Fair and Friendly Acquisitions). Often called the 'Warren Buffett of Canada,' Watsa has built Fairfax from a company with $30 million in revenue into a global insurance and reinsurance conglomerate with $30+ bill...
Watsa explicitly models himself on Warren Buffett. Fairfax's structure mirrors Berkshire Hathaway: insurance operations generate float (low-cost capital), which is invested in equities and fixed income for long-term compounding. Watsa's annual shareholder letters are modeled on Buffett's, emphasizing book value per share growth as the key metric. His philosophy centers on: (1) value investing with a focus on buying companies below intrinsic value; (2) long-term thinking -- he often holds positions for a decade or more; (3) contrarian willingness to go against the crowd; (4) focus on downside protection and margin of safety. However, Watsa diverges from Buffett in important ways: he has been far more willing to make large macro bets (massive short positions on equity indices and credit defa...
Fairfax runs a diversified insurance conglomerate with a concentrated equity investment portfolio. The equity portfolio is relatively concentrated -- top 10 holdings typically represent 60-70% of equity investments. Key characteristics: (1) heavy emerging market exposure, particularly India (Fairfax India Holdings manages $3B+ in Indian assets including IIFL Finance, Thomas Cook India, Bangalore International Airport, CSB Bank, and other Indian companies); (2) large positions in turnaround/distressed situations -- BlackBerry (held since 2013, $500M+ debenture conversion), Eurobank (Greece, bought during crisis at extreme distress), Stelco (Canadian steel, bought out of bankruptcy); (3) a mix of wholly-owned subsidiaries and public equity positions; (4) significant fixed income portfolio (~...
Mixed but ultimately strong over the full period. From 1985 to 2024, Fairfax's book value per share has compounded at approximately 18-19% annually -- a remarkable long-term record. However, the record has two very distinct periods: (1) 1985-2006: Exceptional performance, book value compounded at 25%+ annually, driven by shrewd insurance acquisitions and prescient equity investments. Watsa correctly bet against the dot-com bubble and profited enormously from 9/11 reinsurance dynamics. (2) 2007-2020: A 'lost decade' driven by massive equity deflation hedges that cost $4B+, poor equity picks (BlackBerry, Resolute Forest Products), and a stubborn deflationary/bearish macro thesis that was wrong during one of the greatest bull markets in history. Book value per share was roughly flat from 2010...
High transparency for a public company. Watsa writes detailed annual shareholder letters (15-25 pages) modeled on Buffett's, discussing investment philosophy, mistakes, portfolio positions, and Fairfax's long-term strategy. Quarterly earnings calls are informative. Fairfax publishes detailed investment portfolio data in its annual reports. The annual meeting is modeled on Berkshire's, with a full day of Q&A. However, some complexity in the corporate structure (Fairfax India, Fairfax Africa, numerous insurance subsidiaries, intercompany transactions) makes it harder to fully understand the consolidated picture. Related-party transactions (Watsa family members on boards of subsidiaries) have drawn some criticism. Overall, above-average transparency for an insurance holding company.
Generally high, with some caveats. Watsa is widely respected in the Canadian business community for his ethical conduct and long-term thinking. He has been transparent about his mistakes (the $4B+ in deflation hedge losses, the BlackBerry investment). He maintains a modest public profile and lives relatively modestly for a billionaire. He has been consistent in his philosophical approach for nearly 40 years. However, several concerns: (1) the dual-class share structure gives him voting control disproportionate to his economic ownership -- a governance concern; (2) some related-party transactions have been questioned (family members involved in Fairfax-affiliated entities); (3) in 2006, Fairfax sued a group of hedge funds for $8 billion, alleging a conspiracy to manipulate its stock price d...
Insurance: Odyssey Group (global reinsurance), Crum & Forster (US specialty insurance), Brit Insurance (UK/Lloyd's), Allied World Assurance (global specialty), Zenith National Insurance. Equity investments: Eurobank (major Greek bank, largest equity holding, bought at distressed prices during 2012-2015 Greek crisis), BlackBerry (held since 2013 via debentures and equity, net contributor despite controversy), Thomas Cook India (majority owned, Indian travel conglomerate), Bangalore International Airport (through Fairfax India), IIFL Finance and IIFL Securities (India financial services), CSB Bank (India), Recipe Unlimited (Canadian restaurant chain, Kelsey's/Montana's/Harvey's), Stelco (Canadian steel, bought out of bankruptcy, sold profitably), Kennedy Wilson (US real estate, preferred sha...
High relevance. Watsa's philosophy is very closely aligned with ours: he is a value investor focused on downside protection, long-term holding, and buying below intrinsic value. His insurance float model is the closest public analog to Buffett's approach. His willingness to be contrarian and buy distressed assets (Eurobank at crisis lows, Stelco out of bankruptcy) demonstrates the kind of 'little chance of losing money at this price' analysis we seek. The 2020-2024 renaissance shows the power of patience. However, key cautions for us: (1) his macro hedging was a massive and prolonged error -- it shows even smart contrarians can be wrong for years; (2) his stubbornness (holding BlackBerry for 10+ years, maintaining deflation hedges for 7+ years) can be a vice as well as a virtue; (3) the In...
Gavin Baker is the founder and CIO of Atreides Management LP, a long-short equity hedge fund he launched in 2019 after leaving Fidelity Investments. At Fidelity, he was one of the youngest portfolio managers in the firm's history, managing the Fidelity OTC Portfolio fund -- one of Fidelity's largest and most prominent tech-focused funds with approximately $15-20 billion in AUM. He managed the OTC Portfolio from 2009 to 2019, a period during which the fund significantly outperformed its benchmark. Before becoming a PM, he was a tech analyst at Fidelity, joining the firm in 2000. He is a graduate of Harvard University. Baker is known for his deep understanding of technology business models, his active presence on Twitter/X where he shares detailed investment theses and industry analysis, and...
Baker's philosophy is growth-oriented but grounded in fundamental analysis and business quality assessment. His key principles: (1) Focus on secular winners in technology -- he invests in companies benefiting from long-term technology trends (cloud, AI, semiconductors, digital advertising, e-commerce) and is willing to pay premium valuations for companies he believes are structural winners; (2) Deep industry expertise -- he combines Fidelity-trained fundamental research rigor with a deep understanding of technology ecosystems, competitive dynamics, and product cycles; (3) Variant perception -- he looks for situations where his understanding of a technology trend or company trajectory differs meaningfully from consensus; (4) Concentration in highest-conviction ideas -- his top 10 holdings r...
Concentrated long-short equity with a technology focus. Top 10 holdings represent approximately 74% of the long portfolio -- highly concentrated by hedge fund standards. Total positions: 49 equities + 7 options. The portfolio is heavily weighted toward large-cap technology and AI beneficiaries. Based on 13F filings, his top positions have included names like NVIDIA, Meta Platforms, Microsoft, Amazon, Alphabet, Taiwan Semiconductor (TSMC), and other AI infrastructure and platform companies. He uses options selectively for risk management or leveraged exposure. Holding periods appear moderate (quarters to years), with some positions held since fund inception. He runs a meaningful short book as well, though short positions are not disclosed in 13F filings. The fund is structured as a hedge fu...
Strong. Atreides Management has generated cumulative returns of approximately 173% from inception (2019) through Q4 2025, with a Q4 2025 return of 13.17%. This significantly outperforms the S&P 500 over the same period. Before Atreides, Baker managed the Fidelity OTC Portfolio from 2009-2019, where he oversaw approximately $15-20B in assets and outperformed the Nasdaq Composite over his tenure. His track record across both Fidelity and Atreides spans approximately 15 years of public equity management with strong risk-adjusted returns. His biggest wins appear to be in AI/semiconductor positions (NVIDIA, TSMC) where his early conviction and willingness to hold concentrated positions paid off enormously. His short book performance is less transparent but his overall fund returns suggest the l...
Moderate-high. Baker files quarterly 13F reports disclosing long equity positions, providing portfolio visibility. He is exceptionally active on Twitter/X, where he shares detailed investment theses, industry analysis, and real-time commentary on technology trends -- this is unusual for a hedge fund manager and provides significant insight into his thinking. However, his short positions, options strategies, and detailed performance data are not publicly available. The fund is a private hedge fund, so investor letters and detailed analytics are only available to LPs. Fee structure is not publicly disclosed but is assumed to be standard hedge fund terms (2% management fee, 20% performance fee). His public commentary on AI and technology is among the most valuable freely available investment ...
Appears high. Baker left a secure, well-compensated position at Fidelity to start his own fund, putting his conviction into action. He has been consistent in his technology-focused, fundamental-analysis-driven approach across both Fidelity and Atreides. His public commentary on Twitter/X is substantive and analytical rather than promotional -- he engages seriously with counterarguments and shares detailed reasoning. He does not appear to front-run his public commentary with trading (his positions are disclosed quarterly, and his public views align with his known holdings). He has no known ethical issues, regulatory problems, or conflicts of interest. His willingness to share detailed investment thinking publicly, despite running a hedge fund, suggests intellectual confidence and a desire t...
Based on 13F filings (Q4 2025), top positions include: NVIDIA (largest or near-largest position), Meta Platforms, Microsoft, Amazon, Alphabet, Taiwan Semiconductor (TSMC), and other AI infrastructure and platform companies. The portfolio is heavily tilted toward AI beneficiaries across the tech stack -- from chips (NVIDIA, TSMC) to cloud platforms (Amazon AWS, Microsoft Azure, Google Cloud) to AI application companies (Meta). He has also held positions in semiconductor equipment companies, enterprise software, and other technology sectors. His portfolio reads as a who's who of AI infrastructure and platform companies, reflecting his deep conviction in the AI investment thesis.
Gavin Baker is highly relevant to us. His concentration level (74% in top 10) aligns well with our preference for concentrated portfolios. His deep AI/technology expertise directly supports our AGI thesis -- he is perhaps the most articulate public equity investor on AI infrastructure demand, semiconductor supply chains, and the economic implications of AI. His 13F filings provide a useful reference for AI-exposed positions we might consider. His Twitter/X commentary is an excellent free resource for understanding technology investment dynamics. HOWEVER, there are important differences: (1) he runs a long-short fund, while we are long-only; (2) his approach is growth-oriented, not value-oriented -- he is willing to pay premium valuations that we might consider too expensive; (3) he does no...
Bill Ackman (b. 1966) is an American billionaire activist investor and founder of Pershing Square Capital Management, a hedge fund managing approximately $16-18B in AUM. He graduated from Harvard College and Harvard Business School. He co-founded Gotham Partners in 1992, which closed after a series of failed investments. In 2004 he launched Pershing Square, which became one of the most prominent activist hedge funds. Ackman is known for his highly concentrated, high-conviction activist positions where he takes large stakes and pushes for operational or governance changes. He runs one of the most concentrated portfolios in the hedge fund world, typically holding only 8-12 positions. He also launched Pershing Square Tontine Holdings, the largest-ever SPAC ($4B) in 2020, which ultimately fail...
Ackman's philosophy blends value investing with activist engagement. He seeks 'simple, predictable, free-cash-flow-generative' businesses with durable competitive advantages that he can buy at a discount to intrinsic value. He focuses on large-cap, high-quality businesses where he can identify a catalyst for value realization — often through operational improvements, capital structure changes, or strategic shifts that he actively pushes for. He has described his approach as buying 'great businesses at fair prices' rather than 'fair businesses at great prices,' increasingly moving toward quality over deep value. His investment horizon is medium to long-term (2-5 years typically), but he can hold winners much longer (e.g., Hilton, Chipotle). He uses fundamental analysis, builds detailed fina...
Extremely concentrated: typically 8-12 positions, with top 5 holdings representing 70-80%+ of the portfolio. Long-biased with occasional short positions (most notably the disastrous Herbalife short). Recent 13F filings show core holdings including Alphabet (GOOGL), Hilton Worldwide (HLT), Brookfield Corporation (BN), Restaurant Brands International (QSR), Howard Hughes Holdings (HHH), Chipotle Mexican Grill (CMG), Nike (NKE), and Seaport Entertainment. He has evolved from pure activist plays toward owning high-quality compounders. The Pershing Square Holdings (PSH) closed-end fund trades on the London Stock Exchange and has persistently traded at a wide discount to NAV (20-30%), which led to the attempted Pershing Square USA IPO in 2024 (ultimately pulled).
Mixed but with periods of exceptional returns. Since inception in 2004, Pershing Square has generated approximately 15-16% net annualized returns, outperforming the S&P 500. Major wins include: Canadian Pacific Railway (turned $1.4B into $3.6B through activist campaign), Chipotle (bought during food safety crisis, 3-4x return), a legendary $2.6B profit from a $27M COVID hedge in March 2020 (one of the greatest single trades ever), and Hilton Worldwide (held since 2018, significant compounder). Major losses include: Valeant Pharmaceuticals ($4B loss — his worst investment ever, nearly destroyed the fund), Herbalife short ($1B+ loss over 5 years in a very public battle with Carl Icahn), JC Penney ($500M+ loss), Target activist campaign (loss), and the failed Pershing Square Tontine SPAC. His...
High transparency for a hedge fund. Ackman frequently makes detailed public investment presentations (sometimes 100+ slides), publishes annual letters, and is extremely active on social media where he shares market views and investment rationale. Pershing Square Holdings (PSH) reports monthly NAV. However, he can be selectively transparent — sometimes using publicity as a tool for his activist campaigns. His positions are visible through 13F filings quarterly. He is one of the most publicly visible hedge fund managers in the world.
Generally high but with notable controversies. The Valeant debacle raised questions about his due diligence and judgment — the company engaged in predatory drug pricing and accounting irregularities while he was on the board. His very public Herbalife short, while ultimately wrong, was motivated partly by genuine concern about the company's MLM model. His COVID hedge was legal and brilliant but some criticized the timing of his public comments about market risks while holding the hedge. More recently, his political activism (anti-DEI, anti-Harvard campaigns) has been polarizing. He has generally been forthright about his losses and has acknowledged mistakes publicly. No personal fraud or legal issues. His SPAC failure was embarrassing but he returned all capital to investors.
Current core portfolio (as of late 2024/early 2025 13F): Alphabet (GOOGL) — largest position, Hilton Worldwide (HLT), Brookfield Corporation (BN), Restaurant Brands International (QSR), Howard Hughes Holdings (HHH), Chipotle Mexican Grill (CMG), Nike (NKE), Seaport Entertainment. Historical notable positions: Canadian Pacific Railway, Valeant Pharmaceuticals, Herbalife (short), General Growth Properties, Chipotle (bought during crisis).
Moderate-high relevance. Ackman's concentrated, conviction-driven approach aligns well with our philosophy. His focus on high-quality businesses with durable moats and his willingness to hold winners for years (Hilton, Chipotle) are aligned. His evolving move toward quality compounders over deep value activist plays brings him closer to our style. However, key differences exist: (1) he uses activist engagement as a catalyst, which we don't do, (2) he has historically used leverage and short positions, which we avoid, (3) his investment horizon is typically 2-5 years, shorter than our 5-10+ year preference, (4) he can be emotional and ego-driven in positions (Herbalife), (5) his risk management has failed spectacularly at times (Valeant). His concentrated style and willingness to make big b...
Philippe Laffont (born 1968 in France) founded Coatue Management in 1999 in New York City. He is the brother of Jean-Marie Eveillard (value investing legend) -- correction: Laffont worked at Tiger Management under Julian Robertson before starting Coatue. He graduated from MIT (BS in Electrical Engineering and Computer Science) and holds strong technical credentials unusual among hedge fund managers. This technical background has been central to Coatue's investment approach. Coatue has grown to manage approximately $40.0 billion in 13F-reported assets as of Q4 2025, making it one of the largest technology-focused hedge funds in the world. The firm has also built a significant venture capital arm, similar to Tiger Global. Net worth estimated at $5-7 billion.
Technology-focused, research-intensive investing with a strong emphasis on understanding technological disruption. Laffont's approach: (1) Deep technology expertise -- his MIT engineering background gives him genuine technical understanding of the companies he invests in, (2) Technology sector focus -- Coatue is primarily a technology investor, which has been both its strength and risk, (3) High conviction -- top 10 holdings represent 83.4% of portfolio, (4) Disruption-forward -- Coatue specifically looks for companies driving or benefiting from technological disruption, (5) Both public and private investing -- significant venture capital activity alongside the hedge fund, (6) AI/AGI thesis -- Coatue has been one of the most vocal institutional investors on the AI theme, with Laffont frequ...
Highly concentrated technology-focused portfolio. 52 equity holdings with top 10 representing 83.4% of portfolio. AUM approximately $40.0B (13F), making it one of the largest tech-focused funds. Predominantly technology sector with some exposure to adjacent sectors (fintech, healthcare tech, consumer tech). Active in both public markets and private venture investing. Uses long and short strategies. Q4 2025 showed -0.81% return. The portfolio is essentially a concentrated bet on technology leadership and disruption themes.
Strong long-term track record, particularly impressive given the technology sector focus. Coatue has delivered estimated 15-18% annualized returns since inception in 1999. Key aspects: (1) Navigated the 2000 tech bubble relatively well despite being tech-focused, (2) Strong performance through the 2010s tech bull market, (3) 2022 was likely challenging given heavy tech concentration, but Coatue's diversification within tech (not just high-growth) and shorting capability likely limited losses relative to Tiger Global, (4) Has maintained strong returns while scaling to $40B AUM, which is impressive, (5) The venture capital arm adds additional return potential (and risk). Laffont's technical background has given Coatue an edge in understanding technology companies that pure financial analysts...
Moderate transparency through 13F filings. Coatue has been more publicly vocal about investment themes than most hedge funds, particularly around AI/technology. Laffont gives presentations at conferences and has shared Coatue's AI thesis publicly. The 13F filings with 52 holdings provide good visibility into the public portfolio. However, private investments are not disclosed, and the short book is not visible. More transparent on themes/philosophy than most hedge funds, but standard on specific holdings.
Strong integrity record. No fraud, insider trading, or regulatory scandals. Laffont is known as a serious, technically-minded investor who avoids flashy behavior. The firm's growth from $0 to $40B has been steady and organic. Concerns: (1) Like Tiger Global, Coatue's venture arm deployed capital aggressively during 2020-2021, which raised questions about discipline, (2) The rapid growth of AUM could indicate fee-maximization over return-maximization, though performance has remained strong. Overall, a clean record with minor concerns about venture deployment pace.
As of Q4 2025 (13F), Coatue's $40B portfolio is concentrated in technology leaders. Historical and likely current top holdings include Meta Platforms (META), Nvidia (NVDA), Taiwan Semiconductor (TSM), Microsoft (MSFT), Amazon (AMZN), and other AI/technology leaders. Coatue has been one of the most prominent investors in the AI theme, with significant positions in semiconductor and AI infrastructure companies alongside platform companies. The portfolio reads as a concentrated bet on the AI/technology ecosystem.
High relevance -- the most AGI-aware investor in this group. Positives: (1) Laffont's MIT engineering background gives him genuine technical understanding of AI/AGI, not just financial analysis, (2) Coatue's portfolio is essentially an AGI beneficiary portfolio -- heavy in AI infrastructure, platforms, and semiconductors, (3) High concentration (83.4% in top 10) aligns with our conviction-based approach, (4) Laffont has publicly articulated an AI thesis that aligns with our AGI-by-2030 assumption, (5) The technical expertise means Coatue's technology picks are informed by real understanding, not just momentum. Negatives: (1) Growth/momentum bias rather than downside protection, (2) Uses shorts and venture investing unlike our approach, (3) $40B AUM means positions are in mega-cap tech (lim...
Interesting investors but not perfect matches. Check periodically for ideas.
Philip Arthur Fisher (1907-2004) was a pioneering growth investor who founded Fisher & Company in 1931 and ran it for nearly 70 years until his retirement in 1999 at age 91. He is best known for his 1958 book 'Common Stocks and Uncommon Profits,' which was the first investment book to make the New York Times bestseller list and remains a classic. Fisher studied at Stanford Graduate School of Business, worked briefly as a securities analyst, then launched his own firm during the Great Depression. He was intensely private — he rarely gave interviews, had very few clients (he deliberately kept his firm small), and did not seek publicity. Warren Buffett has said he is '85% Graham, 15% Fisher,' acknowledging Fisher's profound influence on his evolution from pure value investing to paying fair p...
Fisher's philosophy centered on finding outstanding companies with above-average growth potential and holding them for very long periods — ideally forever. His approach was deeply qualitative, the opposite of Graham's quantitative screens. His key concepts: (1) The 'Scuttlebutt' method — extensive research through talking to customers, competitors, suppliers, former employees, and industry experts before investing; (2) Fifteen points to look for in a common stock — covering sales growth potential, R&D effectiveness, profit margins, management quality, labor relations, and long-range outlook; (3) When to sell (almost never) — only sell if the original reasons for buying have changed, you made a mistake in your analysis, or the company no longer meets your criteria; (4) Focus on companies wi...
Extremely concentrated. Fisher typically held fewer than 10 stocks, with his top 3-4 positions comprising 75%+ of his portfolio. He would spend months researching a single company before investing and then hold for decades. His holding periods were measured in decades, not years — he held Motorola for over 20 years, Texas Instruments for similar periods, and FMC Corporation for over 30 years. He bought Motorola in 1955 and held it until his death. Fisher explicitly argued that owning a few outstanding companies was far superior to diversifying across many average ones. He was patient to an extreme degree, willing to wait indefinitely for the right opportunity and then concentrate heavily when he found it.
Fisher's exact returns are not publicly documented because he ran a private firm with no obligation to disclose performance. However, his results can be inferred from his known holdings: his Motorola investment, made in 1955, appreciated roughly 2,000-fold by the time of his death in 2004 — one of the greatest individual stock picks in history. His investments in Texas Instruments, Dow Chemical, and FMC Corporation similarly produced extraordinary multi-decade returns. His firm operated profitably for nearly 70 years, an extraordinary longevity record. Buffett, Munger, and other legendary investors have repeatedly credited Fisher's influence and acknowledged the superiority of his results in growth stock selection. While we cannot cite precise annualized returns, the evidence strongly sugg...
Fisher was notably private and non-transparent about his specific holdings and returns. He rarely gave interviews, did not publish his portfolio, and kept his client list small and exclusive. However, he was extraordinarily transparent about his methodology — 'Common Stocks and Uncommon Profits' lays out his entire analytical framework in granular detail, including his 15-point checklist, his scuttlebutt research method, and his sell criteria. He also wrote two follow-up books: 'Paths to Wealth Through Common Stocks' (1960) and 'Conservative Investors Sleep Well' (1975). So while his positions were opaque, his process was fully disclosed. This is the opposite of most hedge funds today, which disclose positions (via 13F) but keep their process proprietary.
Fisher's integrity was exceptional. He deliberately kept his firm small rather than growing assets under management, prioritizing investment quality over fee income. He maintained the same investment approach for nearly 70 years without style drift. He was honest about the difficulty of his approach and the mistakes he made along the way. He did not chase trends or fads. He was loyal to his clients and his philosophy. His decision to retire at 91 rather than hand off to someone who might dilute his approach speaks to his commitment to doing things right. He was universally respected by peers, clients, and the investment community.
Motorola — bought in 1955, held for nearly 50 years, approximately 2,000x return. Texas Instruments — early investor in the semiconductor revolution. FMC Corporation — held for over 30 years. Dow Chemical — long-term holding capitalizing on chemicals industry growth. Raychem — early investment in specialty chemicals/materials. Fisher focused on technology and chemical companies with strong R&D capabilities, management depth, and long-duration competitive advantages. His emphasis on R&D-driven companies with sustainable innovation pipelines was decades ahead of its time.
Fisher is highly relevant to our approach in several critical ways: (1) Extreme concentration — Fisher's 5-10 stock portfolio matches our 'very few investments' philosophy perfectly; (2) Ultra-long holding periods — his decade-plus holding periods align with our 5-10 year horizon; (3) Qualitative deep-dive analysis — his scuttlebutt method and 15-point checklist parallel our 9 analysis areas and 563-question framework; (4) Focus on great businesses — his emphasis on exceptional companies with durable competitive advantages matches our 'fundamentally great companies with secular tailwinds' priority; (5) Willingness to pay fair prices — like us, Fisher understood that a great business at a fair price beats a mediocre business at a cheap price. The main gap is AGI awareness (obviously, given ...
Born in 1938 in Montreal, Canada. Died in 2011 in London from a degenerative neurological condition (progressive supranuclear palsy). Educated at McGill University (B.Com) and became a Chartered Accountant. Started his investment career at a securities firm in Vancouver. In 1975, he took over a small mutual fund (the All-Canadian Venture Fund) and transformed it into the Cundill Value Fund, which became one of the most successful global value funds in history. His approach was deeply influenced by Benjamin Graham's 'Security Analysis' and 'The Intelligent Investor.' Cundill was one of the first Canadian fund managers to invest globally, seeking value opportunities wherever they existed around the world. In 2000, he sold his firm to Mackenzie Financial, which renamed the fund the Mackenzie ...
Pure Benjamin Graham disciple — one of the most faithful practitioners of Graham's quantitative value approach in the second half of the 20th century. Cundill focused obsessively on buying companies trading below net asset value (NAV), preferably below net-net working capital. His primary screen was price-to-book value: he wanted to buy assets for less than they were worth in liquidation. He would travel the world — Japan, Korea, Europe, distressed emerging markets — to find pockets of deep value that other investors overlooked. He was a true global contrarian, buying during crises (Japan in the 1990s, Asian crisis in 1997, European distress). His checklist was rigorous: price below book value, honest management, no excessive leverage, identifiable catalysts for value realization. He belie...
Globally diversified deep value with moderate concentration. Typically held 40-60 positions across multiple countries and continents. Positions sized at 1-5% of the portfolio, with larger positions in highest-conviction ideas. Heavy emphasis on Japanese net-nets in the 1990s-2000s, European small caps, and distressed situations globally. Very low turnover — held positions for years, waiting patiently for catalysts. Comfortable with obscure, illiquid, and forgotten companies in markets that other investors ignored. Would often be the only Western investor looking at certain Japanese or Korean small caps. The portfolio was genuinely global in a way that few value funds are, spanning North America, Europe, Asia, and emerging markets.
Outstanding long-term performance. The Cundill Value Fund compounded at approximately 15% annualized from 1975 to 2005, dramatically outperforming global indices over that 30-year period. This is one of the best long-term track records in Canadian investment history. The fund turned early investors into multi-millionaires. Performance was particularly strong during periods of global distress, as Cundill's contrarian approach allowed him to buy assets cheaply when markets panicked. He made exceptional returns in Japanese equities in the 1990s and early 2000s, buying net-net companies trading at fractions of book value. After the sale to Mackenzie in 2000 and Cundill's declining health, the fund's performance moderated, and it eventually lost its distinctive edge as it was folded into Macken...
High (through his diaries and biography). Cundill kept incredibly detailed investment diaries for decades, recording his thought processes, analyses, travel observations, and emotional states during investment decisions. These diaries form the backbone of his biography 'There's Always Something to Do,' which provides extraordinary transparency into how a master value investor actually thinks and operates day-to-day. The diaries reveal not just what he bought, but why, how he assessed risk, when he was uncertain, and how he handled losses. This level of transparency into the actual cognitive process of investing is rare and extremely valuable. During his active management years, fund reports and regulatory filings provided standard portfolio transparency.
Very high. Cundill was a deeply private and principled individual who never sought the spotlight. He let his results speak for themselves and was honest about the difficulties and uncertainties inherent in value investing. His sale of the firm to Mackenzie in 2000 was handled professionally, ensuring continuity for investors. His philanthropic activities were substantial but quiet — the Peter Cundill Foundation at McGill University continues to support education in value investing. He was a man of discipline in all areas of his life — the marathon running and adventuring reflected the same patience, endurance, and willingness to suffer short-term discomfort for long-term rewards that characterized his investing. His biography reveals a person of genuine integrity who cared more about getti...
Japanese net-net companies (dozens of small caps trading below net working capital in the 1990s-2000s), Bre-X Minerals (avoided despite initial temptation — a famous case study in his discipline), various European small caps, Korean holding companies trading at deep discounts, distressed emerging market equities during the Asian crisis, and Canadian resource companies. Cundill was also known for buying real estate investment vehicles and closed-end funds trading at large discounts to NAV. His portfolio was genuinely eclectic and global, defying easy categorization beyond 'cheap assets worldwide.'
High relevance as an intellectual framework and role model, though not directly followable (legacy investor, died 2011). Cundill's philosophy of buying assets below liquidation value is deeply aligned with our floor price approach. His global scope, patience, and willingness to buy during crises are qualities we aspire to. His biography 'There's Always Something to Do' is essential reading for anyone pursuing our investment approach. His rigorous checklist-based methodology and his emphasis on price-to-book as a starting screen provide practical tools. The limitation is that he is a legacy investor — there is no living fund to follow, no current portfolio to track. His relevance is entirely in the intellectual framework and historical case studies. He also had no exposure to technology or ...
Benjamin Graham (1894-1976) is universally regarded as the father of value investing and security analysis. Born in London, raised in New York, he graduated from Columbia University at 20 and went to Wall Street. After being nearly wiped out in the 1929 crash, he developed the systematic, disciplined approach to investing that became the foundation of modern value investing. He taught at Columbia Business School for decades, where his students included Warren Buffett, Walter Schloss, Irving Kahn, and Bill Ruane. He co-authored 'Security Analysis' (1934) with David Dodd and wrote 'The Intelligent Investor' (1949), which Buffett calls 'the best book on investing ever written.' He ran Graham-Newman Corporation from 1926 to 1956, a partnership that consistently outperformed the market. His int...
Graham's philosophy centers on three foundational concepts: (1) Margin of Safety — buy securities at a significant discount to intrinsic value to protect against errors in analysis and unforeseen events; (2) Mr. Market — treat the stock market as an emotional counterparty who offers prices daily, sometimes irrationally high, sometimes irrationally low — exploit his mood swings rather than being influenced by them; (3) Intrinsic Value — every security has a calculable value based on its assets, earnings, dividends, and financial position, independent of its market price. Graham preferred quantitative screens: stocks trading below net current asset value (net-nets), low P/E ratios, adequate dividend yield, strong balance sheets, and consistent earnings history. He was deeply skeptical of qua...
Highly diversified quantitative value approach. Graham typically held 50-100+ positions simultaneously, explicitly rejecting concentration. He treated investing as statistical arbitrage across a basket of cheap securities rather than conviction-based concentrated bets. He sought stocks trading below 2/3 of net current asset value (working capital minus all liabilities), P/E below 10, dividend yield above 2/3 of AAA bond yield, and price-to-book below 1.0. His approach was mechanical and formula-based, designed to work without deep qualitative analysis. He also engaged in merger arbitrage, liquidations, hedged convertibles, and other special situations at Graham-Newman.
Graham-Newman Corporation operated from 1926 to 1956 and achieved approximately 17% annual returns versus about 12% for the S&P 500 — roughly 5% annual outperformance sustained over 30 years. This is remarkable given the period included the Great Depression, World War II, and significant market volatility. His single greatest investment was GEICO, which Graham-Newman acquired 50% of in 1948 for $712,000 — an investment that eventually grew to be worth hundreds of millions. Ironically, GEICO was a concentrated, qualitative bet that violated many of Graham's own mechanical rules, yet it generated more profit than all his other investments combined. After Graham-Newman closed, Graham continued to research and refine his quantitative screens, eventually concluding that simple multi-factor valu...
Graham was extraordinarily transparent in sharing his methods. He literally wrote the textbooks on security analysis and value investing, holding nothing back. His books 'Security Analysis' and 'The Intelligent Investor' lay out his entire framework in detail. He taught openly at Columbia for decades. He published his quantitative criteria explicitly, knowing that even if everyone followed them, the approach would still work because human psychology prevents most people from executing a disciplined value strategy. His intellectual generosity was remarkable — he freely shared ideas that could have been kept proprietary.
Graham's integrity was beyond question. He was motivated by intellectual contribution as much as profit. After being nearly ruined in the 1929 crash (which he took personally as a failure), he spent the rest of his career developing systems to prevent such losses. He was honest about his mistakes and limitations. He charged fair fees at Graham-Newman. He mentored dozens of students who went on to become legendary investors, never seeking credit or compensation for their success. His partnership with David Dodd was marked by mutual respect and intellectual honesty. Warren Buffett has consistently described Graham as the most generous and honest mentor he ever had.
GEICO (Government Employees Insurance Company) — acquired 50% in 1948 for $712,000, became worth hundreds of millions and was eventually fully acquired by Berkshire Hathaway. This was Graham's greatest single investment and, ironically, a qualitative bet on a great business rather than a typical net-net. Other holdings were typically dozens of obscure, cheap, small-cap value stocks — net-nets trading below liquidation value. Graham-Newman also engaged in merger arbitrage and special situations. Graham's approach was explicitly not about finding great businesses but about buying adequate businesses at bargain prices.
Graham is the intellectual grandfather of our entire approach. His margin-of-safety concept directly maps to our 'floor price' philosophy — finding prices where there is 'little chance of losing money.' His emphasis on downside protection first, upside second, is precisely our framework. His net current asset value approach is the purest form of floor-price analysis. However, there are important divergences: (1) Graham was highly diversified (50-100+ positions) while we prefer concentration; (2) Graham was skeptical of qualitative analysis while we emphasize understanding the business deeply; (3) Graham's mechanical approach doesn't incorporate technological disruption or AGI considerations; (4) Graham explicitly avoided trying to identify great businesses, while we seek 'fundamentally gre...
Bill Gurley is a general partner at Benchmark, one of Silicon Valley's most prestigious and disciplined venture capital firms. Before joining Benchmark in 1999, he was a top-ranked research analyst at Credit Suisse First Boston covering the internet sector, and before that he worked at Compaq Computer. He holds a BS in computer science from the University of Florida and an MBA from the McCombs School of Business at the University of Texas at Austin. At 6'9", he is one of the most physically imposing figures in venture capital, and he played basketball in college. At Benchmark, he has been responsible for some of the most successful venture investments in history, most notably Uber (one of the greatest VC returns ever -- Benchmark's ~$12M investment was worth ~$7B+ at IPO), as well as inves...
Gurley's philosophy centers on marketplace economics, network effects, and competitive advantage analysis. His key principles: (1) Focus on marketplaces and platforms with strong network effects -- he believes the most valuable technology businesses are those that connect buyers and sellers and become more valuable as they grow; (2) Deep unit economics analysis -- he is famous for analyzing take rates, contribution margins, and the path to profitability with quantitative rigor unusual in VC; (3) Skepticism of growth-at-all-costs -- he was an early and vocal critic of unprofitable growth, particularly in the era of WeWork and other 'unicorns' that burned cash without clear unit economics; (4) Understanding of capital markets distortions -- he gave a famous talk at the All-In Summit about ho...
As a VC at Benchmark, Gurley's portfolio style is inherently different from public market investing. Benchmark is known for extreme concentration and discipline: they raise small funds (~$425M), make concentrated bets (typically 5-7 new investments per fund per year across the entire partnership), and each partner leads deals independently. There is no investment committee -- each partner has full authority. The equal-partnership model means there is no incentive to do bad deals to increase personal economics. Benchmark invests primarily at Series A/B stage in technology companies, with a focus on marketplaces, enterprise software, and consumer technology. Holding periods are long (5-10 years from investment to liquidity). On the public market side, Gurley's personal investments and views ...
Outstanding. Bill Gurley is one of the most successful venture capitalists in history. Benchmark's investment in Uber is one of the top 5 greatest VC returns ever -- approximately $12 million turned into $7+ billion. Beyond Uber, his other notable returns include Zillow (IPO 2011, massive appreciation), GrubHub (IPO 2014), OpenDoor (SPAC 2020), and Stitch Fix (IPO 2017). Benchmark as a firm has been one of the top-performing VC firms for over two decades, with consistently strong fund returns. Gurley's individual track record within Benchmark is among the best at the firm. His public market commentary has also been prescient: his warnings about the ZIRP-fueled unicorn bubble were validated when many overvalued private companies imploded in 2022-2023. His critique of the IPO process and adv...
High for a VC, moderate overall. Gurley's 'Above the Crowd' blog is one of the best sources of technology investment thinking available. He publishes detailed analytical posts examining marketplace economics, competitive dynamics, and capital markets issues. He is a regular speaker at conferences (All-In Summit, various tech events) and gives thoughtful, substantive interviews. He is candid about his views and willing to take controversial public positions (e.g., criticizing the IPO process, warning about the unicorn bubble). However, Benchmark does not publicly disclose fund performance, portfolio holdings, or investment decisions -- standard for VC. Gurley's personal public market investments are not disclosed. Fee structure: standard VC (2% management fee, 20% carry), though Benchmark's...
Very high. Gurley is widely regarded as one of the most principled investors in venture capital. Several indicators: (1) Benchmark's equal-partnership model is rare and reflects genuine commitment to meritocracy and team orientation; (2) Benchmark's deliberately small fund sizes ($425M) sacrifice management fees in favor of return maximization for LPs; (3) Gurley was willing to take an extremely unpopular position on the Uber board, ultimately pushing for CEO Travis Kalanick's ouster when he believed it was in the company's best interest -- this required immense courage and cost him personally in terms of relationships and reputation within the VC community; (4) his public criticism of the IPO process put him at odds with Wall Street banks who are important to VC exits; (5) he has been con...
As a VC: Uber (most notable -- one of greatest VC returns ever), Zillow, GrubHub, OpenDoor, Stitch Fix, Nextdoor, Docker, DoorDash (early relationship), and numerous other technology companies. Benchmark has also been an investor in companies like eBay, Twitter, Snapchat, Discord, and others across the partnership. Gurley's personal public market holdings are not disclosed, but his analytical work suggests interest in marketplace businesses, platforms with network effects, and companies with strong competitive moats.
Bill Gurley is moderately relevant to us. His analytical framework -- deep unit economics, marketplace dynamics, competitive advantage analysis, valuation discipline -- is excellent and transferable to public market investing. His blog posts are worth reading for their intellectual rigor and clarity. His skepticism of growth-at-all-costs and focus on sustainable business models aligns with our value orientation. His willingness to take unpopular positions (Uber board, IPO criticism) demonstrates the kind of intellectual integrity we value. HOWEVER, his primary domain is venture capital, not public market investing, which limits direct applicability. He does not run a public equity portfolio we can track or follow. His views on AI and AGI specifically are not extensively documented -- he ha...
Born 1953 in Pittsburgh, PA. Studied economics at Bowdoin College. Started career at Pittsburgh National Bank, became head of equity research at age 25. Founded Duquesne Capital Management in 1981. Managed money for George Soros at Quantum Fund from 1988-2000, where he actually executed the famous British pound trade (Soros provided the conviction to size it up). Closed Duquesne Capital to outside investors in 2010 to manage his own ~$4B+ fortune as a family office. Widely regarded as one of the greatest money managers ever — averaged ~30% annual returns over 30 years with NO losing year. Known for combining top-down macro analysis with bottom-up stock picking. Net worth estimated at ~$10B+.
Druckenmiller combines macro awareness with concentrated equity positioning. His core principles: (1) 'The way to build long-term returns is through preservation of capital and home runs.' (2) When you have conviction, bet big — 'Put all your eggs in one basket and watch the basket.' (3) Earnings drive stock prices — find companies with accelerating earnings growth before the market recognizes it. (4) Focus on liquidity conditions and the Fed — 'Earnings don't move the overall market; it's the Federal Reserve Board.' (5) Be willing to change your mind instantly. (6) Never risk more than you can afford to lose. He is a blend of macro trader and growth investor, looking for stocks with strong earnings momentum in favorable macro environments. Notably more willing to concentrate than most hed...
Concentrated but actively traded. Duquesne Family Office's 13F filings show 30-60 positions, but the top 10 often represent 50-70%+ of disclosed holdings. He is willing to take 10-20% positions in high-conviction ideas. However, he trades actively — positions change meaningfully quarter to quarter. He has been a significant technology investor, with major positions in AI-related stocks. Recent 13F filings have shown large positions in Nvidia, Microsoft, Coherent, Coupang, Natera, and other growth/tech names. He uses options and has macro positions (currencies, bonds) that don't show up in 13Fs. Holding period tends to be months to a few years, not decades.
Extraordinary. Approximately 30% annualized returns over 30 years (1981-2010) at Duquesne Capital with NO losing year. This is arguably the best risk-adjusted track record in hedge fund history. Key trades: helped execute the 1992 pound short at Quantum, made money during 2000 dot-com crash (after some initial losses going long), navigated 2008 crisis successfully. Since converting to family office (2010+), exact returns unknown but his net worth has grown from ~$3B to ~$10B+, suggesting continued strong performance. Made significant gains from early AI/Nvidia positions in 2023-2024.
Medium-high. Druckenmiller gives frequent interviews and speaks openly about his macro views, his mistakes, and his investment philosophy. He has been candid about his biggest errors (buying tech at the top in 2000). His 13F filings are closely watched and actually reflect meaningful equity positions. However, the macro overlay (futures, options, currencies) is not visible in 13Fs. He does not publish a formal letter or detailed portfolio commentary.
Very high. Druckenmiller returned all outside capital in 2010 because he felt he couldn't deliver the returns clients deserved under stressed market conditions — an extremely rare and honorable move in the hedge fund industry. He has been consistently honest about his mistakes. He is a significant philanthropist, particularly focused on education, poverty, and medical research. He has been vocal about fiscal responsibility and the dangers of US government debt. No scandals, no legal issues, no controversies of substance. Charges no fees (family office).
Recent 13F positions (2024-2025) have included significant AI-related holdings: Nvidia (bought early, traded actively), Microsoft, Coherent (fiber optics/AI infrastructure), Coupang (Korean e-commerce), Natera (genomic testing), Teva Pharmaceutical, Philip Morris, and Woodward. He has actively traded in and out of Nvidia — was early to the AI trade, took profits, re-entered. Also notable short positions and macro bets not visible in 13Fs. Has expressed strong conviction on AI as a transformative technology comparable to the internet.
Moderate relevance. Druckenmiller is the most relevant investor in this group for us. His willingness to concentrate, his focus on earnings power, and his conviction-driven approach share some DNA with our philosophy. His AI/AGI awareness is high and he has positioned aggressively around this theme. However, key differences remain: he trades much more actively (months, not years), he uses leverage and derivatives, he incorporates heavy macro/Fed analysis, and he is not a traditional value investor. We can learn from his thinking on AI companies and his sizing methodology, but we cannot replicate his timing-dependent approach. His 13F positions are worth monitoring for idea generation on AI-adjacent companies.
Howard Marks (b. 1946) is the co-founder and co-chairman of Oaktree Capital Management, which he founded in 1995. He holds a B.S. in Finance from Wharton and an MBA from the University of Chicago. Before Oaktree, he spent 16 years at Citicorp (now Citigroup) where he launched their high-yield bond and distressed debt businesses, then was a partner at TCW Group. Oaktree manages approximately $190+ billion in AUM (as of 2024), making it one of the world's largest alternative investment managers. The firm went public in 2012 and was acquired by Brookfield Asset Management in 2019, though Marks and co-founder Bruce Karsh continue to run investments. Marks is the author of 'The Most Important Thing: Uncommon Sense for the Thoughtful Investor' (2011) and 'Mastering the Market Cycle' (2018).
Marks is famous for his concept of 'second-level thinking' — going beyond surface analysis to understand what consensus expectations are and where they might be wrong. Core principles: (1) Risk control is the foundation — the goal is asymmetric returns (participate in gains, limit losses). (2) Market cycles are inevitable and understanding where you are in the cycle is critical. (3) The relationship between price and value determines risk, not asset quality alone. (4) Contrarian thinking is essential but not sufficient — you have to be contrarian AND right. (5) 'You can't predict, you can prepare.' (6) Focus on 'buying well' rather than 'buying good' — even the best company is a bad investment at the wrong price. (7) Patient, disciplined, and willing to accept periods of looking foolish. H...
Oaktree's primary focus is distressed debt, high-yield bonds, and credit — NOT public equities. The firm's equity 13F filings are a small part of total operations. Oaktree runs over a dozen strategies including distressed debt, high-yield bonds, emerging market debt, real estate, private equity, infrastructure, and convertible securities. The 13F equity portfolio tends to be moderately diversified with 40-80+ positions, many of which are residual equity holdings from distressed debt conversions (e.g., companies emerging from bankruptcy where debt was converted to equity). Holding periods in the credit strategies can be 3-5 years; equity holdings from conversions are often sold opportunistically. Recent 13F holdings have included T-Mobile, various energy companies, and positions resulting f...
Oaktree's flagship distressed debt funds have generated approximately 20%+ gross returns annualized since inception, with remarkably low loss rates. The firm's track record is built on credit, not equity — they excel in buying distressed and defaulted debt at deep discounts and either holding to recovery or converting to equity through restructuring. During the 2008-09 financial crisis, Oaktree deployed $6+ billion at the market bottom and generated extraordinary returns. However, Oaktree's equity returns are harder to track as they are not the firm's primary strategy. Marks himself acknowledges that in strong bull markets, their conservative approach underperforms, but over full cycles, the risk-adjusted returns are exceptional.
Exceptionally high transparency. Marks has written 100+ investment memos since 1990, all freely available on Oaktree's website. These memos are among the most widely read and respected pieces of investment writing in the world. Warren Buffett has said 'When I see memos from Howard Marks in my mail, they're the first thing I open and read.' Marks has also written two excellent books, gives frequent interviews and lectures, and is very open about his thinking process, mistakes, and market views. He is arguably the most transparent and educational major investor alive today.
Very high integrity. Marks and co-founder Bruce Karsh have significant personal capital invested in Oaktree's funds. The firm has a strong culture of investor alignment. No major scandals or regulatory issues. Marks is consistently honest about what he doesn't know, the limitations of his approach, and periods when his views were wrong. The Brookfield acquisition raised some questions about whether Marks would step back, but he has remained actively involved in investment decisions and memo-writing. Marks has been forthright about the challenge of managing $190B+ and the impact of AUM on returns.
Oaktree's notable investments are primarily in credit, not equity: major positions in distressed debt during the 2008-09 crisis, investments in Lehman Brothers claims, Tribune Company debt, Energy Future Holdings, various oil and gas restructurings. In equities (via 13F), holdings have included T-Mobile, various post-restructuring equity positions, and opportunistic public equity investments. The firm's most famous trades are in the credit/distressed space — buying bonds at 20-50 cents on the dollar during crises and recovering par value or converting to equity.
Moderate alignment. Marks' philosophy of risk control, margin of safety, and contrarian thinking aligns well with our approach. His writings on market psychology and cycles are invaluable for any investor. However, Oaktree is primarily a credit/distressed debt shop, not a public equity investor — their 13F is not particularly useful for generating equity investment ideas. The firm manages $190B+, which limits the types of investments they can make. Marks himself is more of a thinker/writer about investing than a stock-picker — his value is in his frameworks and mental models rather than specific positions to follow.
O. Mason Hawkins is the founder and Chairman of Southeastern Asset Management, a Memphis, Tennessee-based investment firm he founded in 1975. Southeastern manages the Longleaf Partners family of mutual funds, which include the Longleaf Partners Fund (US large-cap value), Longleaf Partners Small-Cap Fund, and Longleaf Partners International Fund. Hawkins is a CFA charterholder and graduated from the University of Florida. He has been managing money for approximately 50 years, making him one of the longest-tenured value investors in the United States. Southeastern is 100% employee-owned, and employees have approximately $1.2 billion of their own capital invested alongside clients -- one of the highest co-investment levels in the industry. The firm's average client tenure is 24 years, reflect...
Hawkins's philosophy is deeply rooted in Ben Graham and Warren Buffett's value investing tradition, with distinctive characteristics: (1) Concentrated portfolios of 18-22 'best ideas' -- he believes diversification beyond 20 positions dilutes conviction and returns; (2) 60% rule -- he targets buying businesses at 60 cents on the dollar or less, requiring a significant margin of safety before making an investment; (3) Long-term orientation -- 5+ year investment horizon, explicitly stated and practiced; (4) Engaged value investing -- unlike passive value investors, Hawkins actively engages with management teams to drive value creation, including board representation, strategic input, and activism when necessary. He describes the firm's approach as 'long-term, concentrated, engaged value inve...
Highly concentrated -- Longleaf Partners Fund typically holds 18-22 positions, one of the most concentrated mutual funds in the US. The top 10 positions represent 60-75% of assets. Cash positions have historically ranged from 5-30%, reflecting Hawkins's willingness to wait for opportunities. Sector allocation varies significantly over time based on where he finds value -- he has had large concentrations in media (Liberty Media, Level 3 Communications), real estate (Cheung Kong, CK Hutchison), financials, energy, and industrials at various points. Long-only, no leverage, no shorting. Very low turnover -- positions are held for many years. The firm also engages in significant international investing, reflecting Hawkins's willingness to go wherever value exists globally. He has been particula...
Mixed long-term track record with significant periods of both outperformance and underperformance. From inception in 1987 through approximately 2006-2007, Longleaf Partners Fund had an exceptional track record, compounding at approximately 13-14% annualized and dramatically outperforming the S&P 500. Hawkins was considered one of the top value investors in the country during this period. However, the 2008-2019 period was very difficult: the financial crisis hit several of his holdings hard, and the subsequent decade of growth stock dominance left his deep value, concentrated approach significantly behind the S&P 500. AUM declined from $30-40 billion to $5-8 billion as performance lagged and investors withdrew capital. Key painful positions included Dell (before the buyout), Chesapeake Ener...
High transparency. As a mutual fund manager, Southeastern files regular holdings disclosures. The firm publishes detailed quarterly and annual shareholder letters that are among the most substantive in the industry -- they explain the investment thesis for every holding, discuss mistakes openly, and provide intrinsic value estimates for the portfolio. Hawkins and his team have historically been very accessible to shareholders through annual shareholder meetings, phone calls, and written communication. The $1.2 billion employee co-investment is prominently disclosed. The firm's investment principles are clearly articulated and consistently applied. Fee structure is transparent and includes a unique fee structure that has historically been lower than industry average (the firm waived a porti...
Very high integrity -- one of the strongest integrity profiles in the mutual fund industry. The $1.2 billion employee co-investment (approximately 15-20% of total AUM) represents one of the highest alignment ratios in the industry. The firm is 100% employee-owned. Hawkins has been managing money for 50 years without any fraud, scandal, or regulatory issue. He has been transparent about mistakes and willing to accept responsibility for underperformance. He closed funds to new investors during periods of strong performance to prevent asset bloat from diluting returns -- sacrificing fee income for investment performance. He has fought to protect shareholder rights, including engaging in activism against management teams who were not acting in shareholders' interests. His 24-year average clien...
Recent and historical notable holdings include Liberty Media / Liberty Broadband (John Malone complex), FedEx, Lumen Technologies (formerly CenturyLink/Level 3), CK Hutchison (Li Ka-shing conglomerate), CNX Resources, General Electric, Fairfax Financial Holdings, Affiliated Managers Group, Mattel, Williams-Sonoma, MGM Resorts, EXOR (Agnelli family holding), and various international conglomerates. The portfolio often includes complex holding company structures and sum-of-the-parts opportunities that the market undervalues. Hawkins has historically gravitated toward businesses with hidden asset value, owner-operators, and companies undergoing transformation.
Mason Hawkins is highly relevant to our approach in terms of philosophy and structure. His emphasis on 'not losing money first' directly mirrors our floor price philosophy. His concentration level (18-22 positions) is close to our ideal. His 5+ year holding period matches our horizon. The $1.2 billion co-investment demonstrates maximum skin in the game. His willingness to hold cash when no opportunities exist shows genuine discipline. His engagement with management aligns with our management assessment focus. However, significant concerns: (1) his track record over the past 15+ years has been poor -- deep value, concentrated investing has been punished in a growth-dominated market, and some of his stock picks have been genuinely bad (Chesapeake Energy, various European holdings); (2) the t...
Oxford-educated, Harvard MBA. Founded Aquamarine Fund in 1997. Famous for paying $650,100 (with Mohnish Pabrai) for a charity lunch with Warren Buffett in 2008, which he credits as life-changing. Author of 'The Education of a Value Investor' (2014), a candid memoir about his transformation from a Gordon Gekko-aspiring investment banker to a Buffett-style value investor. Relocated from New York to Zurich specifically to remove himself from Wall Street noise and groupthink. Deeply influenced by Buffett, Munger, and behavioral psychology. Manages a relatively small fund (~$200-300M AUM). Known more for his philosophical approach to investing and life than for specific stock picks.
Buffett/Munger-style value investing with heavy emphasis on behavioral discipline and temperament. Core principles: invest in what you understand, buy with a margin of safety, hold for the long term, and most importantly - create an environment and set of habits that minimize behavioral errors. Spier has developed an elaborate system of personal rules (no checking stock prices during market hours, no talking to management, cloning great investors) designed to counteract psychological biases. Believes the investor's temperament and environment matter more than analytical skill. Focuses on high-quality businesses with durable competitive advantages. Very low portfolio turnover. Strongly influenced by the Buffett lunch experience, which shifted him from trying to be clever to trying to be dis...
Concentrated, long-only, low turnover. Typically holds 8-15 positions with large weightings in top holdings. Has historically held positions in Berkshire Hathaway, Alphabet/Google, Mastercard, Nestle, and other high-quality compounders. Practices 'cloning' - deliberately copying ideas from investors he admires (Buffett, Pabrai, others). Portfolio is heavily tilted toward established, wide-moat businesses. Does not short. Does not use leverage. Very patient holding periods - some positions held for 10+ years. The portfolio is designed to be low-maintenance and resistant to behavioral errors.
Aquamarine Fund has compounded at roughly 7-10% annualized net since inception in 1997, which roughly matches or slightly trails the S&P 500 depending on the measurement period. This is a respectable but not outstanding track record - it reflects the fact that Spier's approach is designed more for capital preservation and behavioral discipline than for outperformance. He has avoided major drawdowns, which is valuable. The fund's performance during the 2008-2009 crisis was acceptable. Spier would argue that the track record understates his approach's value because it doesn't capture the peace of mind and behavioral benefits. Objectively, the returns are average for a value fund.
Moderate-to-high. Spier wrote a candid book about his investing journey, including his mistakes and psychological struggles. He speaks at value investing conferences. However, he does not publish detailed quarterly letters publicly, and Aquamarine Fund's actual performance data is not widely disclosed. He shares his general philosophy extensively but is less transparent about specific positions and real-time decision-making than some peers. His book is one of the most honest investor memoirs ever written.
Very high. Spier's entire investing philosophy revolves around personal integrity and ethical behavior. He was deeply influenced by Buffett's emphasis on reputation. He has been candid about his early career mistakes (working at a firm that was essentially a boiler room, which he left). He relocated to Zurich specifically to avoid the ethical compromises of Wall Street culture. He donates to charity and emphasizes stakeholder treatment. His integrity appears genuine and deeply held, not performative.
Berkshire Hathaway, Alphabet/Google, Mastercard, Nestle, Ferrari, Microsoft, and other blue-chip quality compounders. Portfolio changes slowly. Has historically cloned ideas from Pabrai and other value investors.
Moderate. Spier's buy-and-hold, concentrated, downside-focused approach aligns well with our philosophy. His emphasis on behavioral discipline and creating systems to avoid psychological errors is directly relevant. His portfolio of quality compounders is the type of company we'd analyze. However, his returns are average, he is not a deep analyst in the forensic/quantitative sense, and his 'cloning' approach means he's typically a follower rather than an originator of investment ideas. His lack of engagement with the AGI thesis limits his forward-looking relevance. Most useful for: behavioral investing lessons, portfolio construction philosophy, and as a pointer toward other great investors.
Matthew McLennan is the Head of the Global Value Team at First Eagle Investments, a position he has held since 2008. He co-manages the First Eagle Global Fund, First Eagle Overseas Fund, and First Eagle Gold Fund, collectively managing approximately $50-60 billion in assets. McLennan is originally from Australia, where he earned a Bachelor of Commerce from the University of New South Wales. Before joining First Eagle, he was a partner at Southeastern Asset Management (Longleaf Partners) and before that spent a decade at First Eagle from 1998-2004 as an analyst under Jean-Marie Eveillard. He then left for Southeastern (2004-2008) before returning to First Eagle to succeed Eveillard as the lead portfolio manager. McLennan is considered Eveillard's intellectual successor, carrying forward the...
McLennan's philosophy is deeply rooted in the Benjamin Graham tradition of margin of safety, with strong influence from his mentor Jean-Marie Eveillard. Core tenets: (1) Absolute return orientation — he does not benchmark against indices but aims to preserve and grow capital in real terms. (2) Margin of safety is paramount — he seeks to buy businesses at significant discounts to intrinsic value to protect against permanent loss of capital. (3) Gold as a hedge — the First Eagle Global Fund maintains a meaningful allocation to gold and gold-related investments (typically 5-15% of the fund) as a hedge against monetary debasement and tail risks. This is an unusual feature among equity funds. (4) Global opportunity set — he invests across geographies without constraint. (5) Quality matters — he...
The First Eagle Global Fund is moderately diversified, typically holding 100-200 positions, but with meaningful concentration in the top 20. Top 10 holdings generally represent 25-35% of the fund. The fund is truly global, investing across US, European, Asian, and emerging markets. A distinguishing feature is the consistent allocation to gold bullion and gold mining stocks, which serves as portfolio insurance. The fund holds both equities and gold, making it somewhat unique. Sector exposure tends to be overweight in consumer staples, financials, industrials, and materials, with underweight in technology relative to global indices. The fund also tends to hold meaningful cash positions (5-15%) when the team cannot find attractive opportunities. AUM is substantial at $50-60 billion, which doe...
The First Eagle Global Fund has one of the strongest long-term track records in the mutual fund industry, though much of its legendary performance came under Eveillard's tenure (1979-2004). Under McLennan's leadership since 2008, the fund has delivered solid risk-adjusted returns with notably lower volatility and smaller drawdowns than global equity indices. The fund's hallmark is downside protection — it has historically captured much less of market declines than the MSCI World, while participating in a significant portion of upside. Annualized returns under McLennan have been approximately 7-9% (after fees), modestly trailing the MSCI World in strong bull markets but significantly outperforming in downturns (2011, 2015-16, 2018, 2020). The fund's Sharpe ratio has been competitive due to ...
Good transparency for a mutual fund. First Eagle publishes detailed quarterly commentaries with thoughtful discussion of portfolio positioning, market views, and specific investment rationales. McLennan is a thoughtful writer and speaker who provides genuine insight in his commentaries, rather than boilerplate language. He gives periodic interviews and presentations at investor conferences. Holdings are disclosed quarterly. The fund's unique gold allocation is well-explained in their investor materials. However, like all large mutual funds, there is a delay between portfolio actions and disclosure.
Very high integrity. McLennan inherited a stewardship tradition from Eveillard that prioritizes investor capital preservation above asset gathering. He has maintained the fund's distinctive approach (gold allocation, cash reserves, absolute return orientation) even when it caused relative underperformance in strong bull markets. He has not style-drifted to chase performance. He is known for intellectual honesty and humility, acknowledging uncertainty and the limits of his own knowledge. He invests meaningfully in his own funds. No known ethical controversies or regulatory issues.
The First Eagle Global Fund has historically held: gold bullion (physical gold, a signature position), Berkshire Hathaway, Philip Morris International, Oracle, Exxon Mobil, Comcast, Schlumberger, British American Tobacco, Bank of New York Mellon, Danone, and various European industrials and consumer staples companies. Gold mining positions have included Barrick Gold, Newmont, Agnico Eagle. The portfolio tends toward high-quality, cash-generative businesses with strong balance sheets.
High relevance. McLennan's philosophy is closely aligned with our own: absolute return orientation, margin of safety, downside protection first, willingness to hold cash, and focus on avoiding permanent loss of capital. His global approach and gold allocation demonstrate creative thinking about portfolio construction. His emphasis on humility and acknowledging the limits of prediction is intellectually honest. The preservation-first mandate matches our 'little chance of losing money' philosophy. However, his portfolio is too diversified (100-200 names) compared to our ideal concentrated approach, and his fund size creates constraints we don't face. His gold allocation is a distinctive feature worth studying — it represents a systematic approach to hedging tail risks that we should consider...
Ian Cumming (1940-2018) and Joseph Steinberg (born 1944) ran Leucadia National Corporation together for over three decades, from 1978 until 2012 when the company merged with Jefferies Group. The pair took control of Leucadia in 1978 when it was a small, troubled conglomerate. Cumming served as Chairman and Steinberg as President. They were often called the 'baby Berkshire' by Wall Street, a comparison they embraced. Cumming graduated from Harvard Law School and had a background in corporate restructuring. Steinberg had a similar background in corporate finance and turnarounds. Together, they transformed Leucadia from a small company into a diversified conglomerate with interests in banking (AmeriCredit/auto lending), telecommunications (WilTel Communications), real estate, beef processing ...
Cumming and Steinberg were classic opportunistic value investors with an emphasis on distressed and special situations. Their philosophy had several distinctive elements: (1) Buy businesses and assets at deep discounts to intrinsic value, often during periods of distress. They were willing to buy into sectors and situations that were deeply unpopular. (2) Concentrate capital in their best ideas -- Leucadia's portfolio was typically concentrated in 5-10 major investments. (3) Long-term holding periods -- they often held investments for 5-15+ years. (4) Operational improvement -- unlike passive investors, they actively worked to improve operations at portfolio companies. (5) Flexible and opportunistic -- they invested across industries, asset types, and geographies, following value wherever ...
Leucadia's portfolio was highly diversified across industries but concentrated in the number of positions. At any given time, Leucadia might own 5-10 major businesses/investments spanning completely different sectors. Key historical investments: AmeriCredit (auto lending, bought cheap, grew into a large subprime auto lender, eventually sold to General Motors in 2010 for $3.5B), WilTel Communications (fiber optic network, bought from bankruptcy for pennies, sold to Level 3), National Beef (one of the largest US beef processors), Crimson Wine Group (California wineries), Idaho Timber, MFC Bancorp (global metals trading), FXCM (forex trading platform, bailed out during Swiss franc crisis), Garcadia (auto dealerships), and various real estate investments. The style was contrarian and opportuni...
Strong over the full 1978-2012 period. Leucadia's book value per share compounded at approximately 19% annually from 1978 to 2012 -- exceptional by any standard and comparable to Berkshire Hathaway over the same period. The stock price went from roughly $1 (split-adjusted) to over $25 at the time of the Jefferies merger. Key wins: AmeriCredit (enormous return, bought at distressed prices, sold to GM for billions), WilTel Communications (bought from bankruptcy for ~$500M, sold for $1B+), various real estate investments made at cyclical lows. Key losses: Some of the smaller investments (MFC Bancorp, FXCM bailout, Sanchez Energy) produced losses in the later years. The post-2008 period was weaker as the duo aged and the opportunity set shifted. The Jefferies merger in 2012 effectively ended t...
Moderate. Cumming and Steinberg wrote annual shareholder letters that were short, direct, and honest. They did not hide losses or spin failures. However, the letters were quite brief compared to Buffett's or Watsa's -- sometimes just 2-3 pages. Leucadia's SEC filings were standard public company disclosures. The complexity of the conglomerate structure (many different businesses across many industries) made it somewhat difficult to assess the full picture. They did not seek publicity and were relatively unknown outside of value investing circles. Post-merger, Jefferies Financial Group provides standard public company disclosure. Joe Steinberg remains visible through Jefferies board activities.
High. Cumming and Steinberg had strong reputations for ethical conduct and shareholder alignment. Key positives: (1) They owned significant personal stakes in Leucadia, ensuring alignment with shareholders. (2) They took modest compensation relative to their peers, though not as extreme as Buffett's $100K. (3) They were honest about failures in their letters. (4) They did not engage in financial engineering or governance entrenchment. (5) They treated employees and business partners fairly. (6) The Jefferies merger was done at reasonable terms. The FXCM bailout (2015) raised some questions -- Leucadia provided a $300M bailout to the forex platform after the Swiss National Bank unpegged the franc, and the terms were very favorable to Leucadia, but FXCM had limited alternatives. Overall, the...
Historical (Leucadia era): AmeriCredit (auto lending, sold to GM 2010), WilTel Communications (fiber optics, sold to Level 3), National Beef Packing (major US beef processor), Crimson Wine Group (Pine Ridge, Archery Summit wineries), Idaho Timber, MFC Bancorp/FXCM, Garcadia (auto dealerships), Jefferies Group (pre-merger equity stake), various real estate. Current (Jefferies Financial Group): Primarily Jefferies investment banking and capital markets, with legacy interests in National Beef (still held), Vitesse Energy (oil & gas), JETX Energy, HomeFed Corporation (real estate), Linkem/Tessellis (Italian telecom/broadband). Joe Steinberg remains Chairman of JEF.
Moderate relevance. Cumming and Steinberg's philosophy aligns well with our approach: buy at distressed prices where there's 'little chance of losing money,' hold long-term, concentrate in best ideas, and focus on tangible asset value. Their track record validates the approach. Their opportunistic, cross-sector style is interesting -- they didn't constrain themselves to any particular industry, following value wherever it appeared. However, several factors limit their relevance: (1) Leucadia as an entity no longer exists -- it merged into Jefferies in 2012 and Ian Cumming passed away in 2018. (2) We cannot follow their current activity because the Leucadia model is gone. (3) Their investment style (operational turnarounds of private businesses) is not directly replicable for public equity ...
Henry Ellenbogen is the founder and CIO of Durable Capital Partners LP, an investment firm he founded in 2019 with offices in Chevy Chase, Maryland. Before founding Durable Capital, Ellenbogen spent 17 years at T. Rowe Price, where he became one of the most successful growth fund managers in the industry. He managed the T. Rowe Price New Horizons Fund from 2010 to 2019, a $20B+ small/mid-cap growth fund with a storied history dating back to 1960. Under Ellenbogen, the New Horizons Fund significantly outperformed its benchmark and peers. He also co-managed or had influence over the T. Rowe Price Global Technology Fund. Ellenbogen is known for his ability to identify high-growth companies early -- both in public and private markets -- and hold them through multiple stages of compounding. At ...
Ellenbogen is a growth-at-a-reasonable-price (GARP) investor with a focus on identifying 'durable growth' companies -- businesses with strong competitive advantages, large addressable markets, and the ability to sustain above-average growth for extended periods. His key principles: (1) Invest in companies with structural growth drivers that can compound for 5-10+ years; (2) Focus on the intersection of technology and large traditional industries being disrupted (fintech, e-commerce, cloud, digital health); (3) Identify companies with network effects, high switching costs, and data advantages that create durable competitive moats; (4) Invest early in the growth cycle -- he is willing to invest in private companies pre-IPO and hold through the transition to public markets (crossover investin...
Concentrated growth portfolio. Durable Capital's 13F shows approximately 40 positions, but the top 10 represent about 81% of the portfolio -- extremely top-heavy. The fund invests across public and private markets (crossover structure). Key sectors: technology, internet, consumer technology, fintech, and healthcare technology. The portfolio likely includes significant private market positions (SpaceX, Stripe, and other late-stage private companies) that do not appear on the 13F. Public positions tend to be in high-quality growth compounders -- think Shopify, ServiceNow, Snowflake, CrowdStrike, and similar companies that benefit from digital transformation and cloud adoption. Ellenbogen's style is distinctly growth-oriented: he seeks companies with 20%+ revenue growth, expanding margins, an...
Strong track record across two decades. At T. Rowe Price, the New Horizons Fund under Ellenbogen significantly outperformed the Russell 2000 Growth Index and peer group from 2010-2019, generating estimated annualized returns in the mid-to-high teens. He was recognized as Morningstar's Fund Manager of the Year for domestic equity in 2019, which is one of the most prestigious awards in the mutual fund industry. At Durable Capital Partners (2019-present), performance has been more volatile: 2020 was likely very strong (growth stocks rallied), 2021 was likely positive, 2022 was almost certainly difficult (growth stocks sold off sharply), 2023 was likely a strong recovery, and Q4 2025 showed -5.72% (reflecting broader growth stock weakness). The fund's growth from startup to $10.6B in AUM in ap...
Moderate transparency. Durable Capital files 13F reports quarterly, providing visibility into public equity holdings. However, the fund's private market investments (potentially a significant portion of AUM) are not disclosed through 13Fs. Ellenbogen gives occasional interviews and has spoken at investment conferences, but he is not a prolific public communicator. He does not publish investor letters publicly. His prior track record at T. Rowe Price is well-documented through Morningstar and other public mutual fund data. Overall, the public portfolio is followable through 13F filings, but the full picture (including privates and performance) requires investor access.
High integrity. Ellenbogen built his reputation through nearly two decades of consistent, legitimate outperformance at T. Rowe Price -- a well-respected, investor-aligned firm. He left T. Rowe Price on good terms to pursue his own vision, which is a positive signal (no acrimony, no burned bridges). His Morningstar Fund Manager of the Year award reflects peer and industry recognition of both skill and ethical standing. He has not been involved in any scandals, fraud, or regulatory issues. The structure of Durable Capital (private fund with significant personal investment) suggests alignment of interests. He is known for being deeply analytical, intellectually honest, and genuinely focused on identifying great businesses rather than promoting himself or extracting fees.
Public (estimated based on 13F patterns and Ellenbogen's historical preferences): likely includes positions in companies like Shopify, ServiceNow, CrowdStrike, Snowflake, Datadog, MongoDB, HubSpot, Uber, DoorDash, and other high-quality growth compounders. Private: likely includes stakes in SpaceX, Stripe, and other late-stage private companies that T. Rowe Price and Durable have historically been active in. His portfolio reflects a strong tilt toward digital economy winners -- cloud infrastructure, cybersecurity, e-commerce platforms, and fintech.
Moderate relevance. Ellenbogen's strengths that align with our approach: (1) Long-term holding orientation -- he thinks in 5-10+ year time horizons; (2) Focus on durable competitive moats; (3) Concentration -- top 10 is 81% of portfolio; (4) Quality management emphasis; (5) Technology exposure positions him well for the AGI era. Key divergences: (1) He is a growth investor, not a value investor -- he does not focus on downside protection, floor prices, or margin of safety in the same way we do; (2) His portfolio is growth-heavy and can suffer significantly in risk-off environments (Q4 2025 was -5.72%); (3) Private market positions are inaccessible and opaque to us; (4) His companies tend to be high-valuation, high-growth businesses that may not fit our 'little chance of losing money' crite...
Bill Miller (born 1950) is the founder and CIO of Miller Value Partners, an investment firm based in Baltimore, Maryland. He is one of the most storied investors in American finance, best known for his record-setting streak of beating the S&P 500 for 15 consecutive years (1991-2005) as the manager of the Legg Mason Capital Management Value Trust. Miller studied economics at Washington & Lee University, did graduate work in philosophy at Johns Hopkins University, and attended Johns Hopkins SAIS. Before Legg Mason, he served as a military intelligence officer during the Vietnam era. He joined Legg Mason in 1981 and became lead portfolio manager of the Value Trust in 1990. His 15-year streak attracted enormous attention and AUM, peaking at over $20 billion. However, the 2008 financial crisis ...
Miller is a contrarian value investor with an unusually flexible interpretation of 'value.' Unlike traditional value investors who focus on low P/E and low P/B ratios, Miller defines value as any stock trading below its intrinsic value -- even if it has high traditional multiples. This led him to buy Amazon in the early 2000s when it traded at enormous P/E ratios, arguing the market undervalued its future cash flows. His key principles: (1) Expected value thinking -- every investment is a probability-weighted bet; (2) Contrarianism -- he actively seeks situations where consensus is wrong; (3) Low price-to-value, not low price-to-earnings; (4) Willingness to average down aggressively -- he added to positions during the 2008 crisis (which initially destroyed returns but eventually proved rig...
Highly concentrated and contrarian. Miller Value Partners' 13F shows approximately 30-35 positions, with the top 10 representing roughly 85% of the portfolio. This is extremely concentrated by institutional standards. Key characteristics: (1) Large single-stock bets -- he is willing to put 10-15%+ of the portfolio in a single name; (2) Mix of value and growth -- portfolio includes traditional value stocks alongside technology and growth companies; (3) Significant cryptocurrency exposure -- he has publicly stated that Bitcoin represents a meaningful allocation in his personal portfolio (reportedly 50%+ of personal net worth at one point); (4) Willingness to hold deeply out-of-favor names; (5) AUM has shrunk significantly -- from $20B+ at Legg Mason to approximately $280M at Miller Value Par...
Extraordinary highs and devastating lows. The 15-year streak (1991-2005) is the longest in mutual fund history -- the Value Trust averaged approximately 14.6% annualized vs. the S&P 500's 12.4% over that period. However, 2006-2008 was catastrophic: the fund lost approximately 55% in 2008 and 65% from peak to trough, driven by large positions in financials (Bear Stearns, AIG, Countrywide) that went to near-zero. This wiped out years of outperformance on a cumulative basis. Post-2012, at Miller Value Partners, his track record has been strong: the Opportunity Trust returned approximately 120% in 2021 (driven by Amazon, Bitcoin exposure, and post-COVID recovery plays). Over the past decade, Miller Value Partners has generally outperformed, though with high volatility. His Bitcoin allocation h...
Moderate-to-high transparency. Miller is a prolific writer and speaker. He published quarterly letters at Legg Mason that became required reading in the investment community. At Miller Value Partners, he continues to share his thinking through letters, interviews, and media appearances. He has been candid about his mistakes (especially 2008) and his evolution as an investor. His 13F filings reveal public holdings. He has been very public about his Bitcoin thesis and his views on technology investing. However, detailed performance attribution and private holdings are not fully public. His willingness to discuss both successes and failures in public makes him one of the more transparent major investors.
High integrity with caveats. Miller has been honest about his failures, which is rare in the investment industry. He did not blame external factors for 2008 -- he acknowledged his positions in financials were wrong and that he underestimated leverage risk. He invested alongside clients and suffered enormous personal losses in 2008 (reportedly losing 90%+ of his personal net worth). He did not engage in fee extraction or marketing gimmicks. He has been a generous philanthropist, donating over $100 million to Johns Hopkins University and other institutions. However, some question whether his 2008 behavior -- continuing to average down into collapsing financial stocks -- reflected conviction or stubbornness, and whether his fiduciary duty to clients was compromised by his refusal to cut losse...
Current/recent (Miller Value Partners 13F): Amazon (historically large position), Bitcoin/cryptocurrency exposure (personal and fund), Alphabet/Google, Meta Platforms, various value and contrarian positions. Historical: Amazon (one of the earliest institutional buyers in the early 2000s), Dell, Kodak (famously wrong), Bear Stearns (catastrophic loss in 2008), AIG (catastrophic loss), Countrywide Financial (catastrophic loss). His portfolio reflects his contrarian approach -- a mix of high-quality compounders and deep value/turnaround situations.
Moderate relevance. Miller's expected-value framework and contrarian thinking are intellectually compatible with our approach. His early identification of Amazon and Bitcoin shows genuine analytical insight and willingness to think independently. His concentration aligns with our preference for focused portfolios. However, key concerns: (1) His 2008 experience is a cautionary tale about concentration without adequate downside protection -- holding Bear Stearns and AIG to near-zero violates our 'little chance of losing money' principle; (2) His willingness to average down into failing businesses conflicts with our floor-price discipline; (3) His cryptocurrency allocation introduces volatility and speculation we would avoid; (4) At age 75+ and with $280M AUM, his current portfolio activity m...
Wallace (Wally) Weitz (b. 1949) is the founder and chairman of Weitz Investment Management, based in Omaha, Nebraska. He holds a degree from Carleton College and an MBA from the University of Chicago. He founded Weitz & Company in 1983 and launched the Weitz Value Fund, which he managed for decades. The firm manages approximately $4-6 billion in AUM across several mutual funds. Weitz is a quiet, disciplined value investor in the Buffett tradition — unsurprising given that he is based in Omaha and has long admired Buffett's approach. He is less well-known than others on this list but has a solid long-term track record. In recent years, Weitz has transitioned portfolio management responsibilities to his team (notably Drew Weitz, his son, and Brad Hinton), while remaining involved as chairman...
Weitz's approach is straightforward Buffett-style value investing: buy good businesses at discounts to intrinsic value and hold for the long term. Core principles: (1) Focus on free cash flow — a company's value is the present value of its future free cash flows. (2) Look for businesses with durable competitive advantages (moats). (3) Seek management teams that allocate capital intelligently. (4) Be patient — wait for the right price, hold for years. (5) Margin of safety — buy at a meaningful discount to estimated intrinsic value. (6) Quality matters — prefers good businesses over cheap-but-mediocre ones. (7) Concentrated but not extreme — typically 25-40 positions. His approach is less contrarian and less special-situations-oriented than Klarman or Greenblatt. He tends toward higher-quali...
Moderately concentrated — typically 25-40 positions across the funds. The top 10 holdings often represent 40-50% of the portfolio, showing meaningful conviction in top ideas while maintaining reasonable diversification. Holding periods are long — many positions held for 3-7+ years. Turnover is low. The portfolio tends toward mid-to-large cap quality businesses across various sectors. Recent top holdings have included Berkshire Hathaway, Liberty Broadband, Meta Platforms, Alphabet, Aon, and various media/telecom companies. The firm has shown willingness to own technology and digital media companies, which differentiates Weitz from some traditional value investors who avoid tech entirely.
Solid long-term track record. The Weitz Value Fund has compounded competitively vs the S&P 500 over its 40+ year history, though like most value managers, it has experienced periods of underperformance during growth-dominated markets (particularly 2015-2020). The Partners III Opportunity Fund, which has more flexibility (can use leverage and short selling), has had periods of strong outperformance. The track record is not as spectacular as Klarman's or early Greenblatt's, but it is consistent, steady, and achieved without the kind of blowups that Berkowitz experienced. Weitz has compounded wealth for his investors over four decades without major permanent capital losses — a testament to his conservative approach.
Good transparency. Weitz writes quarterly letters to fund shareholders that are thoughtful and educational, explaining his investment rationale and market views. These letters are available on the firm's website. He has given interviews and talks at industry events, though he is not as prolific or well-known as Howard Marks. The firm's website provides detailed information on holdings, performance, and investment approach. As a mutual fund company, Weitz Investment Management is required to disclose holdings regularly, providing good visibility into the portfolio. However, Weitz is not a prolific writer or public intellectual in the way that Marks or Greenblatt are.
High integrity. Weitz has a significant personal investment in his funds. The firm has a clean regulatory record with no major scandals or conflicts of interest. Weitz has been honest about periods of underperformance and has not chased fads or changed his approach to boost short-term returns. The transition to the next generation (including his son Drew) has been handled thoughtfully. The firm charges reasonable fees compared to hedge fund alternatives. Weitz has remained committed to Omaha and to his value investing approach for 40+ years, which speaks to consistency and conviction.
Current and recent notable holdings include: Berkshire Hathaway, Liberty Broadband, Meta Platforms, Alphabet, Aon, Markel, Charter Communications, Liberty Media, Burlington Northern (before Berkshire acquisition), various media/telecom companies. Historically, Weitz has shown a preference for media, cable/telecom, insurance, and financial services companies. The ownership of Meta and Alphabet is notable — it shows Weitz is willing to invest in technology companies when they meet his value criteria, unlike many traditional value investors who avoid tech.
Moderate-to-good relevance. Weitz's philosophy of buying quality businesses at reasonable prices with a long-term holding period aligns well with our approach. His willingness to own technology companies (Meta, Alphabet) is a positive signal that his universe overlaps with ours. His moderate concentration (25-40 positions) is more diversified than our target but still shows meaningful conviction in top ideas. The fact that he has held Meta and Alphabet suggests some awareness of technological trends, though he is not AGI-focused. His quiet, steady approach and clean track record without blowups is admirable. The main limitation is that he is less concentrated than we'd prefer and his less-famous status means his ideas generate less signal. His upcoming generation transition also introduces...
Born circa 1968 in Australia. Educated at the University of New South Wales (B.Com, LLB). Started his career in investment banking at Deutsche Bank and Bankers Trust Australia before moving to the buy side. In 2006, he co-founded Magellan Financial Group (ASX: MFG) with Chris Mackay, launching the Magellan Global Fund focused on high-quality global equities. Magellan grew rapidly to become one of Australia's largest and most prominent fund managers, with AUM peaking at over A$100 billion. Douglass was the primary portfolio manager of the flagship Global Fund, which focused on a concentrated portfolio of 20-40 high-quality global companies. He became one of Australia's most prominent investors, known for his articulate explanations of investment theses and his focus on quality businesses wi...
Quality-growth investor focused on a concentrated portfolio of 'wonderful businesses at reasonable prices.' Douglass was heavily influenced by Warren Buffett's later evolution toward quality over deep value. His approach centered on identifying companies with: (1) sustainable competitive advantages (wide moats), (2) long runways for growth, (3) high returns on invested capital, (4) strong free cash flow generation, (5) competent, aligned management teams, and (6) reasonable valuations relative to intrinsic value. He particularly favored large-cap global companies with dominant market positions in growing industries — companies like Alphabet/Google, Microsoft, Meta/Facebook, Visa, and other global platform businesses. His investment process was fundamentally about understanding the business...
Highly concentrated — typically 20-35 positions with top 10 holdings representing 50-70% of the portfolio. This is one of the most concentrated approaches among large Australian fund managers. Focused almost exclusively on large-cap global equities, particularly US-listed mega-caps and global platform companies. Very low turnover — many positions held for 5-10+ years. The portfolio heavily favored technology platforms, payment networks, consumer franchises, and global infrastructure companies. Position sizes in highest-conviction names could reach 8-12% of the portfolio. The portfolio often had 50-70% exposure to US-listed equities, reflecting the dominance of US companies in the 'quality global' universe. Minimal exposure to small caps, emerging markets (except through global companies wi...
Strong overall, with a notable period of exceptional performance followed by a difficult stretch. The Magellan Global Fund returned approximately 11-13% annualized from inception in 2007 through 2020, significantly outperforming the MSCI World Index. Performance was particularly strong during 2011-2019, as the fund's concentration in US quality/growth mega-caps perfectly captured the dominant market trend. The fund navigated the 2020 COVID crash reasonably well, though with more volatility than expected given its quality focus. However, performance deteriorated in 2021-2022: the fund underperformed as rising interest rates hit growth/quality valuations, and Douglass's concentrated bet on Chinese tech (particularly Alibaba) proved costly. The loss on the Alibaba position was significant bot...
High. Douglass was one of the most articulate and transparent fund managers in Australia. He gave regular detailed presentations to investors explaining his investment theses, discussing individual positions, and analyzing market risks. Magellan's quarterly reports were comprehensive. Douglass also participated in podcasts, media interviews, and investor conferences where he explained his thinking in depth. His presentations on topics like the competitive advantages of Alphabet or the risks of Chinese regulation were excellent educational material. As a listed company (ASX: MFG), Magellan's financials and AUM were fully transparent. However, transparency decreased significantly during and after his leave of absence — the circumstances of his departure were never fully explained, and the tr...
Moderate to high with caveats. On the positive side: Douglass maintained a large personal investment in Magellan (MFG shares and fund units), demonstrating skin in the game. His fee structure, while standard, was not extractive by Australian standards. He was consistent in his investment approach and did not chase fads. On the negative side: the circumstances of his departure in 2022 were handled poorly — the abrupt leave of absence with limited explanation created uncertainty for investors and employees. The revelation that he had been dealing with personal issues while managing billions raised questions about governance and disclosure. The firm's dependence on him as a single decision-maker created enormous key-person risk that was not adequately addressed or communicated. The Alibaba po...
Core long-term holdings included Alphabet/Google (often the largest position at 8-10% of fund), Microsoft, Meta/Facebook, Visa, Mastercard, Netflix, Starbucks, and other US-listed global quality companies. Also held positions in SAP, Reckitt Benckiser, and other global franchises. The controversial Alibaba position (2020-2022) became a significant detractor. Infrastructure fund holdings included toll roads, airports (Sydney Airport), utilities, and cell towers. The portfolio was essentially a concentrated bet on global platform businesses with network effects and high barriers to entry — very similar to the 'quality compounders' approach popularized by Fundsmith's Terry Smith.
Moderate-high relevance. Douglass's concentrated, quality-focused approach with long holding periods aligns well with several aspects of our philosophy. His emphasis on understanding competitive advantages deeply, his willingness to concentrate in highest-conviction ideas, and his long-term orientation are all qualities we value. His presentations on individual companies are educational and demonstrate the depth of analysis we aspire to. However, there are important limitations: (1) Douglass is no longer actively managing money, making him a legacy figure for study rather than a live source of ideas. (2) His approach was more 'quality at a fair price' than 'deep value with downside protection' — he was willing to pay up for quality in ways that may not align with our floor-price philosophy...
John Bogle Neff (1931-2019) managed the Vanguard Windsor Fund from 1964 to 1995 — a remarkable 31-year tenure that made Windsor the largest mutual fund in America for a time. Born in Wauseon, Ohio, Neff served in the Navy, studied at the University of Toledo, and earned his MBA from Case Western Reserve. He joined Wellington Management in 1964 and took over Windsor, which he managed for over three decades. Neff was known as 'The Professional's Professional' because more institutional investors and fellow fund managers invested in Windsor than almost any other fund. He was quiet, methodical, and deeply contrarian. His book 'John Neff on Investing' (1999) details his philosophy and track record. He retired in 1995 and passed away in 2019 at age 87.
Neff's approach was systematic contrarian value investing built around his 'Total Return' concept. His framework: (1) Total Return Ratio — (earnings growth rate + dividend yield) divided by P/E ratio. He sought ratios above 2.0, meaning the total return characteristics were at least double what the P/E implied; (2) Low P/E investing — Neff systematically bought stocks in the bottom quintile of P/E ratios, believing that low expectations created asymmetric opportunities; (3) Contrarianism — actively buying into sectors and stocks that were hated, neglected, or misunderstood by the market. He thrived on negative sentiment; (4) Earnings growth focus — not just low P/E but growing earnings, typically 7-20% growth rate, combined with meaningful dividend yields; (5) Sound fundamentals — strong b...
Moderately diversified value portfolio. Windsor typically held 60-100 stocks, more concentrated than an index but less concentrated than our preferred approach. Neff would make meaningful sector bets — when banking was cheap, he'd load up on banks; when energy was hated, he'd buy oil stocks. He was willing to have 15-25% of the fund in a single sector when his Total Return Ratio analysis suggested the opportunity was compelling. Individual positions could be 2-5% of the fund, occasionally larger for highest-conviction ideas. His holding periods were typically 2-4 years — buying when P/E was compressed and selling when it normalized. This is shorter than our preferred horizon but reflects the nature of his contrarian, mean-reversion strategy.
Neff's 31-year track record at Windsor (1964-1995) is one of the longest and most consistent in fund management history. He achieved 13.7% annualized returns versus 10.6% for the S&P 500 — a 3.1% annual outperformance sustained over 31 years. A $10,000 investment in 1964 grew to approximately $564,000 by 1995 versus roughly $233,000 for the S&P 500 — more than double the index. He beat the S&P 500 in 22 of 31 years (71% hit rate). While his annual outperformance was more modest than Lynch or Munger, the duration of his outperformance is exceptional — 31 years of consistent alpha is one of the strongest refutations of the efficient market hypothesis ever recorded. His performance was achieved with moderate risk and volatility, consistent with a low-P/E value approach.
Neff was quite transparent. His book 'John Neff on Investing' provides a detailed year-by-year account of his investment decisions, sector bets, and thinking process over 31 years — one of the most thorough retrospective accounts any fund manager has published. Windsor's quarterly reports disclosed holdings. Neff gave interviews and spoke at investment conferences, though he was less prolific than Lynch or Buffett. His Total Return Ratio formula was explicitly shared, allowing others to replicate his screens. He was open about mistakes and periods of underperformance. His transparency was professional and methodical, reflecting his personality.
Neff's integrity was excellent. He managed Windsor through multiple market cycles over 31 years without style drift, staying true to his low-P/E contrarian approach even when it was deeply out of favor (such as during the late 1990s tech bubble, by which time he had retired). He was modest, avoided self-promotion, and let his results speak for themselves. He invested his own money in Windsor alongside his investors. He charged reasonable fees (Windsor was part of Vanguard's low-cost structure). He was respected universally by peers. The fact that more professional investors chose to invest in Windsor than almost any other fund is perhaps the highest testimony to his integrity and competence.
Neff was a sector rotator rather than a single-stock investor, but notable positions included: Ford Motor Company — bought during the 1980s auto industry downturn, classic contrarian value play. Citicorp — purchased during the early 1990s banking crisis when most investors fled financials. Atlantic Richfield (ARCO) — energy sector value play. Burlington Northern — transportation value. General Motors — auto industry contrarian bet. Neff frequently loaded up on banking, energy, auto, and industrial stocks when they were in the market's doghouse, then sold when sentiment normalized. His approach was more sector-driven than stock-driven.
Neff offers several useful frameworks but is less aligned with our approach than Graham, Fisher, or Munger: (1) His Total Return Ratio is a practical screening tool we could use in our initial filtering; (2) His contrarian discipline — buying what others hate — aligns with our willingness to buy into fear; (3) His emphasis on downside protection through low P/E provides margin of safety similar to our floor-price concept; (4) His 31-year consistency demonstrates the power of disciplined value investing. However, divergences are meaningful: (1) Neff was moderately diversified (60-100 stocks) versus our preference for extreme concentration; (2) His holding periods (2-4 years) are shorter than our 5-10+ year horizon; (3) His mean-reversion approach (buy low P/E, sell when normalized) is diffe...
David Herro is the Chief Investment Officer of International Equities at Harris Associates, the investment advisor to the Oakmark Funds. He has managed the Oakmark International Fund since its inception in 1992 and co-manages the Oakmark International Small Cap Fund. Herro earned a B.S. from the University of Wisconsin-Platteville and an M.A. in economics from the University of Wisconsin-Milwaukee. Before Harris Associates, he worked at the State of Wisconsin Investment Board and Principal Financial Group. Morningstar named him International Stock Fund Manager of the Decade in 2010, a remarkable recognition spanning 10 years of consistent outperformance. He is widely regarded as one of the premier international stock pickers alive today, with over 30 years of continuous management of the s...
Herro is a classic bottom-up value investor applied to international markets. He seeks companies trading at significant discounts to his estimate of intrinsic value, typically 30-40% below what he believes a company is worth. He focuses on three key elements: (1) a strong competitive position or business franchise, (2) management that acts in shareholders' interests and allocates capital wisely, and (3) a stock price meaningfully below intrinsic value. He is willing to hold through volatility and has conviction in concentrated positions. He emphasizes understanding management quality and corporate governance, which is especially critical in international markets where governance standards vary widely. He looks for catalysts that will close the gap between price and value, such as managemen...
Moderately concentrated for a mutual fund — typically 40-60 holdings in the Oakmark International Fund, with the top 10 positions often representing 35-45% of the fund. He runs a benchmark-agnostic portfolio and is willing to have large overweights and underweights relative to the MSCI EAFE index. Geographic allocation is purely a byproduct of bottom-up stock selection. He has historically had significant exposure to European financials (banks, insurance companies) and consumer staples/luxury goods companies. The portfolio is mostly large-cap with some mid-cap exposure. He does not hedge currency risk, believing that over long periods, currency effects wash out. AUM for Oakmark International Fund has been significant, in the range of $20-30 billion at various points.
Exceptional long-term track record. The Oakmark International Fund has significantly outperformed the MSCI EAFE index since its 1992 inception, generating approximately 10-11% annualized returns versus roughly 6-7% for the benchmark over that period. This outperformance earned him the Morningstar International Stock Fund Manager of the Decade award in 2010. However, more recent performance (2015-2022) was more mixed, with value style headwinds and some individual stock misjudgments (notably Credit Suisse) creating periods of underperformance. The fund suffered in 2020 during COVID but recovered strongly in 2021-2022 as value stocks rallied. His track record over 30+ years remains one of the strongest in international equity investing. His ability to add value has been demonstrated across m...
Reasonably transparent for a mutual fund manager. Oakmark publishes quarterly commentaries where Herro explains his positioning and rationale. Holdings are disclosed quarterly per SEC requirements. He gives periodic interviews to financial media (Barron's, Morningstar, Bloomberg) where he discusses his views on specific holdings. Harris Associates publishes detailed investment philosophy documents. However, real-time transparency is limited compared to investors who write detailed annual letters.
High integrity. He has a long track record of sticking to his stated investment philosophy even during difficult periods. During the late 1990s tech bubble, he refused to chase momentum and maintained his value discipline, which cost him short-term performance but proved correct long-term. He has been candid about mistakes, including acknowledging misjudgments on specific stocks. He has managed the same fund for over 30 years, showing commitment. He has significant personal investment in his own funds, aligning his interests with shareholders. No known ethical controversies or regulatory issues.
Historically significant positions have included: Daimler/Mercedes-Benz, Credit Suisse (a notable loss when it collapsed in 2023), Glencore, BNP Paribas, Bayer, CNH Industrial, Reckitt Benckiser, Allianz, Intesa Sanpaolo, Lloyds Banking Group, Samsung Electronics, and various European luxury goods companies. He has shown a willingness to invest in financials and industrials that other investors avoid. More recently he has held positions in GSK (GlaxoSmithKline), Rolls-Royce, and other European industrials benefiting from restructuring.
Moderate relevance. His value approach and emphasis on intrinsic value and downside protection aligns well with our philosophy. His bottom-up approach and focus on management quality are compatible. However, his international-only focus means his portfolio won't overlap much with our likely US-focused opportunities. His portfolio concentration is moderate (40-60 names) — more diversified than our ideal. His fund size creates constraints we don't face. He is useful as a source of ideas for international companies and as a model for how to apply value investing principles in foreign markets. His Credit Suisse loss is instructive on the risks of financial companies with governance issues. His 30+ year track record provides valuable lessons on maintaining discipline through adverse conditions.
Dennis Hong is the Founder and CEO of ShawSpring Partners, a concentrated, long-term-oriented investment firm he founded in 2014. Before founding ShawSpring, Hong worked at Altimeter Capital Management (under Brad Gerstner) and Matrix Capital Management. He began his investment career at the Yale University Investments Office, the endowment managed by the legendary David Swensen, which pioneered the 'Yale Model' of institutional investing. Hong attended Yale University, where he earned a BA in Ethics, Politics & Economics (2005). He enrolled at Harvard Business School but left after his first year to launch ShawSpring. ShawSpring manages approximately $531 million as of Q4 2025, making it a small but highly focused fund. The firm caters to select global institutions including university an...
Hong pursues a single, long-term investment approach focused on generating high absolute returns and meaningful outperformance of market indices. His philosophy centers on: (1) Concentrated portfolio of high-growth businesses -- ShawSpring holds only about 11 positions, making it extremely concentrated; (2) Focus on technology, internet, and consumer sectors with strong competitive advantages and defensible market positions; (3) Emphasis on durable unit economics with attractive free cash flow generation; (4) Industry leadership -- he invests in companies that are or can become category leaders; (5) Management quality -- Hong places exceptional emphasis on 'managerial character and strong management team alignment with shareholder interests'; (6) Multi-year compounding horizons -- the fund...
Ultra-concentrated. ShawSpring holds approximately 11 equity positions, with 100% of the portfolio concentrated in the top 10 holdings. This is among the most concentrated portfolios of any institutional investor. The fund focuses on technology, internet, and consumer companies with strong competitive moats. Given Hong's background at Altimeter and Matrix (both tech-focused funds), the portfolio is likely tilted toward high-quality technology and e-commerce platforms. Potential holdings (based on historical patterns of similar funds and Hong's background) could include positions in companies like Coupang, MercadoLibre, Sea Limited, Shopify, and other global internet/e-commerce leaders, though specific current holdings are not fully detailed in public sources. The $531M AUM is small enough ...
Limited public information on precise track record. ShawSpring was founded in 2014, providing roughly 10-11 years of history. The Q4 2025 return of -9.27% suggests the fund experienced a challenging quarter, likely reflecting weakness in growth/technology stocks. The fund's AUM of $531M after 10+ years is modest, which could reflect either (1) deliberate AUM management to maintain concentration and nimbleness, or (2) performance challenges. The fact that the fund serves prestigious institutional clients (university endowments, hospital endowments, foundations) suggests a credible track record -- these investors typically require a minimum 3-5 year track record with strong risk-adjusted returns before allocating. The fund's concentration (11 stocks, 100% in top 10) means performance is high...
Low-to-moderate transparency. ShawSpring files 13F reports, so public equity holdings are visible. With only 11 positions, the 13F reveals essentially the entire equity portfolio. However, the fund is private and does not publish investor letters, detailed performance data, or investment commentary publicly. Hong rarely gives public interviews or speaks at conferences. The ShawSpring website is minimalist, providing basic information about the firm's philosophy but no specific holdings or returns data. For investors following 13F filings, the extreme concentration makes the portfolio easy to track, but understanding the investment thesis behind each position requires inference rather than direct disclosure.
Appears high, though limited public information makes a full assessment difficult. Hong's training at the Yale Endowment (under David Swensen, who was known for impeccable ethical standards) and his decision to serve institutional clients like endowments and foundations suggest a commitment to fiduciary standards. He left Harvard Business School to start ShawSpring, demonstrating conviction and entrepreneurial courage. The fund's structure (serving institutional clients with patient capital) aligns incentives well. No scandals, fraud allegations, or regulatory issues are publicly known. The small, focused nature of the firm suggests a culture prioritizing investment quality over marketing and AUM growth.
Specific current holdings are not fully detailed in public sources beyond the 13F filing. Based on ShawSpring's stated focus on technology, internet, and consumer sectors with strong competitive advantages, and Hong's background in global internet investing, likely holdings include positions in large-cap technology/internet companies and emerging market internet platforms. The portfolio consists of approximately 11 concentrated equity positions plus options strategies. Given the $531M AUM and 100% top-10 concentration, each position likely represents $30-70M on average.
Moderate-to-high relevance. ShawSpring aligns well with our approach on several dimensions: (1) Ultra-concentration -- 11 positions is very close to our ideal of a highly concentrated portfolio; (2) Long-term compounding orientation -- the fund explicitly targets multi-year holding periods; (3) Focus on competitive advantages and management quality; (4) Technology/internet focus positions the portfolio well for AGI-era investing; (5) Institutional quality (endowment clients) suggests rigorous analysis. Key concerns: (1) Limited public track record data makes it difficult to assess skill vs. luck; (2) Small AUM could indicate performance challenges or deliberate choice; (3) Growth-oriented approach may not prioritize downside protection; (4) Hong is relatively unknown, making it harder to a...
Joel Greenblatt (b. 1957) is the founder of Gotham Capital, a private investment partnership he started in 1985, and later Gotham Asset Management. He holds a B.S. and MBA from Wharton. At Gotham Capital (1985-2005), he compounded at approximately 40% annualized over 20 years, one of the best long-term track records ever recorded. He is a professor at Columbia Business School where he teaches value investing. He is the author of several influential books: 'You Can Be a Stock Market Genius' (1997, on special situations), 'The Little Book That Beats the Market' (2005, introducing the 'Magic Formula'), and 'The Big Secret for the Small Investor' (2011). He co-founded Value Investors Club, an online community of elite value investors. In 2009, he launched Gotham Asset Management, which runs lo...
Greenblatt's philosophy has two distinct phases. (1) Early career (Gotham Capital, 1985-2005): Deep value special situations investing — spinoffs, mergers, restructurings, recapitalizations, rights offerings, and other corporate events that create mispriced securities. Extremely concentrated portfolio (5-8 positions), high conviction, long holding periods. This approach generated the legendary 40% returns. (2) Later career (Gotham Asset Management, 2009-present): Systematic 'Magic Formula' investing — a quantitative screen that ranks stocks by earnings yield (EBIT/EV) and return on capital (EBIT/tangible capital employed). This identifies 'good companies at cheap prices.' The systematic approach is diversified (hundreds of positions) and designed to be scalable. Core underlying principle i...
Two very different styles across career phases. Early Gotham Capital: extremely concentrated (5-8 positions), special situations, high conviction, contrarian. Current Gotham Asset Management: highly diversified systematic approach with hundreds of long and short positions based on Magic Formula rankings. The 13F for Gotham Asset Management shows 500+ positions, many small, reflecting the systematic quantitative approach rather than high-conviction stock picking. Turnover in the systematic strategy is higher (annual rebalancing). The early concentrated approach is far more relevant to our philosophy, but Greenblatt no longer invests that way at scale. His personal investments may still be concentrated, but this is not visible.
Gotham Capital (1985-2005): approximately 40% annualized gross returns over 20 years, one of the best track records in investing history. This was achieved with a concentrated special situations approach. Gotham Asset Management (2009-present): performance has been more mixed. The Magic Formula systematic approach has underperformed the S&P 500 in several recent years, particularly during growth-dominated markets (2015-2021). The long/short structure creates additional headwinds in persistent bull markets. Academic backtests of the Magic Formula show strong historical returns, but live implementation has been challenging. Greenblatt has been transparent about this, noting that the approach requires patience and that most investors abandon it during periods of underperformance, which is exa...
Very high transparency. Greenblatt has written three books that clearly explain his approach in accessible language. He teaches at Columbia Business School and has given numerous interviews and lectures. The Magic Formula is fully disclosed — anyone can replicate it. He founded Value Investors Club, which promotes transparent idea-sharing among investors. His 13F filings are available but less useful due to the systematic/diversified nature of Gotham Asset Management. His early special situations approach is very well-documented in 'You Can Be a Stock Market Genius.'
High integrity. Greenblatt invests his own capital alongside his investors. He returned outside capital at Gotham Capital when AUM grew too large for the concentrated special situations approach (similar to Klarman). He has been honest about the challenges of implementing the Magic Formula in live markets. He founded Value Investors Club as a genuine educational community. No scandals or regulatory issues. He has acknowledged that the systematic approach underperforms in certain market regimes and has not oversold it. His transition from concentrated special situations to systematic investing was driven by scalability considerations, not a change in underlying philosophy.
Early Gotham Capital era: famous positions in spinoffs and special situations (specific holdings from this era are less well-documented in public records). Value Investors Club ideas often reflect his analytical approach. Current Gotham Asset Management 13F: hundreds of positions across the market, reflecting the systematic Magic Formula approach — not meaningful for individual stock idea generation. Notable past investments include positions in various spinoffs, restructurings, and corporate events that created mispricings. His books describe specific historical investments in detail (e.g., Host Marriott spinoff, Charter Medical, Wells Fargo).
Mixed relevance. Greenblatt's early concentrated special situations approach (1985-2005) is highly relevant to our philosophy — deep value, concentrated, contrarian, patient. His current systematic approach at Gotham Asset Management is NOT relevant — it's the opposite of our concentrated, few-positions philosophy. His 13F is essentially useless for idea generation due to hundreds of small positions. His books and teaching are extremely valuable for developing analytical frameworks, particularly around special situations and corporate events. The Magic Formula framework (cheap + good quality) aligns with our philosophy conceptually, but the implementation is too diversified. His thinking is relevant; his current portfolio is not.
Bruce Karsh (born 1955) co-founded Oaktree Capital Management in 1995 with Howard Marks, along with several other partners from TCW Group. Karsh serves as Co-Chairman and Chief Investment Officer, managing the firm's distressed debt and credit strategies. Graduated from Duke University and University of Virginia School of Law. Before Oaktree, was a senior member of TCW's distressed debt group and earlier worked at the US Department of Justice and as a corporate attorney. While Howard Marks is the public face and philosophical voice of Oaktree, Karsh is the operational investment decision-maker. Oaktree manages approximately $190B+ in AUM (as of 2024-2025), making it one of the largest alternative investment firms globally. Oaktree was partially acquired by Brookfield Asset Management in 20...
Karsh's philosophy (shared with Howard Marks) is perhaps the most intellectually rigorous in the distressed/credit space. Core principles: (1) Risk control and downside protection are paramount — 'If we avoid the losers, the winners will take care of themselves.' (2) Focus on buying at a discount to intrinsic value, especially in distressed debt where you can buy good assets attached to bad balance sheets. (3) Market timing is less important than asset selection — 'We don't predict; we prepare.' (4) Consistency over brilliance — aim for above-average returns with below-average risk. (5) Contrarian but disciplined — buy when others are forced sellers (margin calls, redemptions, regulatory pressure). (6) 'The most dangerous thing is to buy something at the peak of its popularity.' Karsh appl...
Oaktree's public 13F shows equity holdings (estimated $10-15B), but this represents a small fraction of total AUM. The vast majority of Oaktree's capital is in private credit, distressed debt, real estate, and infrastructure — invisible to public filings. Public equity positions tend to be mid-to-large cap, diversified across sectors. Recent 13F holdings have included significant positions in energy companies, financials, technology names, and special situations. Oaktree's approach is more diversified than concentrated — they spread risk across many credit positions rather than making a few massive bets. The equity portfolio shown in 13F filings may include stocks received through debt-to-equity conversions in restructurings.
Excellent, especially in distressed debt. Oaktree's distressed opportunity funds have been among the best-performing in the alternative investment space. Key achievements: (1) Oaktree's Distressed Opportunities Fund IV (vintage 2007-2008) reportedly generated 30%+ net IRR, deploying capital during the financial crisis to buy distressed corporate debt, RMBS, and bank loans at steep discounts. (2) Oaktree's overall distressed funds have generated approximately 15-20% net annualized returns over the firm's 30-year history. (3) The firm's consistency is remarkable — Oaktree has had far fewer losing periods than most distressed funds because of their emphasis on downside protection. (4) Oaktree's total AUM growth from zero to $190B+ over 30 years reflects sustained strong performance. Karsh per...
Moderate. Oaktree files 13F reports showing public equity positions. Howard Marks publishes his renowned 'Oaktree Memos' regularly (dozens over 30+ years), which provide extraordinary insight into the firm's investment thinking, market views, and philosophical framework. Karsh himself is less public than Marks but participates in conference presentations and investor communications. Oaktree became partially public (listed on NYSE in 2012, later taken private by Brookfield in 2019), during which time it filed public financial statements. However, the bulk of Oaktree's portfolio (private credit, distressed funds) is not visible to outside observers. The Marks memos make the philosophy transparent even if the positions are not.
Very high. Oaktree has an exceptionally clean record over 30 years. No major fraud allegations, no SEC enforcement actions, no scandals. Howard Marks and Bruce Karsh are widely respected in the investment community for intellectual honesty and ethical behavior. The firm's emphasis on 'first, do no harm' and risk control reflects a genuine fiduciary mindset. The Brookfield acquisition in 2019 was structured to maintain Oaktree's operational independence and investment culture. Marks' memos are remarkably honest about what Oaktree does and doesn't know, what they got right and wrong. The firm charges typical alternative investment fees (1.5-2% management, 20% incentive) but performance has justified them. Oaktree has a strong culture of intellectual humility and candor.
Recent 13F equity positions have included various energy companies, financial institutions, and special situation equities. However, the real portfolio is in distressed debt and private credit, which is not publicly visible. Oaktree's most notable investments historically include massive purchases of distressed financial debt during 2008-2009, distressed European debt during 2011-2012, and distressed energy credit during 2015-2016.
Moderate relevance. Karsh/Oaktree's investment philosophy is highly aligned with our 'floor price' and 'little chance of losing money' approach. Howard Marks' concept of 'risk control' and 'asymmetric returns' (participating in upside while limiting downside) is essentially what we're trying to do with our three price targets. The emphasis on buying below intrinsic value, being contrarian, and focusing on downside protection are all shared principles. Key differences: Oaktree is primarily a credit investor (debt, not equity), and their portfolio is mostly opaque (private credit). We can't easily track their positions for equity ideas. They don't focus on technology or AGI themes. However, reading Howard Marks' memos is extremely valuable for developing investment thinking and framework — e...
Founded Greenlight Capital in 1996 at age 27 with $900K in seed capital. Cornell University graduate. Rose to prominence through high-profile short positions, most notably Allied Capital (exposed accounting fraud) and Lehman Brothers (shorted before collapse in 2008). Author of 'Fooling Some of the People All of the Time' documenting the Allied Capital battle. Known for deep fundamental research on both long and short sides. Has been a vocal critic of passive indexing and value investing's underperformance in recent years. Major gold bull since early 2020s, arguing gold is under-owned by institutional investors. Struggled significantly from 2015-2022 as value investing underperformed, but staged a strong comeback in 2022-2024.
Deep value, activist-leaning long/short equity. Einhorn combines fundamental bottom-up analysis with macro awareness. Focuses on finding mispriced securities through detailed forensic accounting and independent thinking. Willing to take concentrated positions and engage publicly when he believes management or accounting is problematic. Has evolved over time: originally pure long/short value, increasingly incorporated macro hedges (gold, inflation trades). Believes markets have become structurally broken due to passive investing, with value stocks systematically underpriced. Uses a 'bubble basket' of shorts against overvalued momentum stocks. Key principle: understand the downside first, look for asymmetric risk/reward. Not a buy-and-hold forever investor - actively manages positions based ...
Moderately concentrated long/short equity fund. Typically 15-25 long positions with top 5-10 comprising majority of portfolio. Maintains a short book, though has reduced short exposure in recent years due to the difficulty of shorting in momentum-driven markets. Significant gold allocation (physical gold and gold-related investments) as an inflation/monetary debasement hedge. Notable positions have included Green Brick Partners (homebuilder where he serves as chairman), Brighthouse Financial, CONSOL Energy, Teck Resources, and HP Inc. Portfolio has shifted more toward real assets and value stocks in recent years. AUM roughly $2-3 billion, down from peak of ~$12 billion.
Exceptional early track record: ~26% annualized net returns from 1996-2007, significantly outperforming the S&P 500. The 2008 crisis was a banner year due to Lehman short. However, performance deteriorated significantly from 2015-2020, with several years of meaningful underperformance as growth/momentum stocks dominated. Lost roughly half of AUM through a combination of poor returns and redemptions. Strong comeback in 2022 (+36.6%), 2023 (+22.1%), and 2024 (~25%). The post-2015 drought lasted long enough to raise legitimate questions about whether his approach had become structurally impaired, though the recent resurgence suggests the style was out of cycle rather than broken. Career CAGR roughly 13-15% net, which is strong but heavily front-loaded.
High transparency. Einhorn is one of the most publicly vocal hedge fund managers. Delivers detailed investment presentations at Sohn Conference, Robin Hood, and other investor events. Publishes quarterly letters that explain thesis in depth. Wrote a full book documenting his Allied Capital short. Regularly appears in financial media. Discloses major positions and reasoning publicly. One of the more transparent hedge fund managers in the industry.
High. Einhorn has demonstrated willingness to fight powerful adversaries when he believed fraud or misrepresentation was occurring (Allied Capital battle lasted years). He was investigated and fined by the UK FSA in 2012 for inadvertent insider trading related to Punch Taverns (received material nonpublic information during a call, then traded - he settled for ~$7.5M but maintained he didn't realize the information was material). This is a minor blemish but not evidence of systemic dishonesty. He has been consistent in his public statements and has not engaged in pump-and-dump behavior. Serves as chairman of Green Brick Partners, aligning his interests with shareholders.
Green Brick Partners (GRBK, chairman), gold/GLD, CONSOL Energy, Brighthouse Financial, HP Inc., Teck Resources, CNH Industrial. Has historically had significant positions in tech value plays. Known short positions have included Tesla, Netflix, Amazon (many of which were painful losses on the short side).
Moderate. Einhorn's downside-first approach and deep fundamental analysis align well with our philosophy. His forensic accounting skills and willingness to dig into balance sheets are directly relevant. However, his long/short approach, macro trading, and active position management diverge from our buy-and-hold concentrated approach. His gold thesis is interesting but tangential. His recent value investing comeback is encouraging. Most useful for: identifying overearning/underearning situations, forensic accounting red flags, understanding short-side risks to our long positions.
Brad Gerstner is the founder and CEO of Altimeter Capital Management, a technology-focused investment firm founded in 2008 and based in Menlo Park, California. Gerstner grew up in Indiana, attended Indiana University and Harvard Business School. Before founding Altimeter, he had a career in private equity and venture capital, including founding General Catalyst Partners and working at PAX Group. Altimeter manages approximately $15-18 billion in AUM across public and private markets. Gerstner is well known for his October 2022 open letter to Mark Zuckerberg urging Meta to cut headcount by 20%, reduce metaverse spending, and cap capex at $25B -- prescient advice that Meta largely followed, leading to the 'Year of Efficiency' and a massive stock rally. He also took Altimeter Growth Corp, a SP...
Gerstner runs a concentrated, high-conviction technology portfolio. He focuses on secular winners in cloud computing, AI, consumer internet, and enterprise software. His approach blends growth investing with an activist edge -- he is willing to publicly push management teams (as with Meta) to create shareholder value. He thinks in multi-year time horizons, often holding positions through volatility. He emphasizes 'enduring growth' companies with network effects, high switching costs, and massive TAMs. He has been an early and vocal proponent of AI as a transformative technology, pivoting his portfolio heavily toward AI beneficiaries since 2023. He is not a deep value investor in the Buffett tradition, but he cares about capital discipline and valuation relative to growth. His SPAC venture ...
Highly concentrated in technology stocks. Altimeter's public portfolio typically holds 15-25 positions, with the top 5 representing 60-70% of the portfolio. Key sectors: cloud/SaaS, social media, ride-sharing, AI infrastructure. The firm also has substantial private market investments. Public/private crossover fund structure. Runs both long-only and long-short strategies. Position sizes can be very large -- Meta has historically been the largest position. Turnover is moderate; he holds core positions for years but actively trims and adds around them.
Strong long-term track record, particularly in the 2020-2025 period. Altimeter's public equity fund has generated strong returns, driven by large positions in Meta, Snowflake, Uber, and other tech leaders. The Meta position was particularly well-timed: Gerstner held through the 2022 crash (Meta fell from $330 to $90), added to the position, wrote the open letter, and rode the recovery to $600+. The Grab SPAC was a notable misstep -- shares fell from $13 at merger to under $4, though they have since partially recovered. Altimeter Growth Corp 2 was not completed. Overall, his hit rate on major tech investments has been high, and his willingness to concentrate has amplified returns. Estimated annualized returns in the mid-to-high teens over the firm's history, with particularly strong 2023-20...
Moderate transparency. Altimeter files quarterly 13F reports disclosing public holdings. Gerstner is publicly visible through interviews, podcasts, and his open letter to Zuckerberg. However, as a private fund, detailed performance figures are not publicly available. The SPAC provided some transparency through public filings. He shares broad thematic views publicly but does not publish detailed investor letters for public consumption.
Generally high integrity. The open letter to Zuckerberg was seen as a principled stand that benefited all shareholders, not just Altimeter. He put his reputation on the line publicly. The Grab SPAC raised some questions -- taking a company public at a $40B valuation that subsequently lost 70%+ of its value is a common SPAC criticism, though Gerstner bore losses alongside other investors. He has not been involved in any fraud or ethical scandals. He advocates for shareholder-friendly capital allocation and has been consistent in his views over time.
Meta Platforms (largest historical position, held through 2022 crash and recovery), Snowflake (early investor, held through IPO and beyond), Uber Technologies, MongoDB, Microsoft, Amazon, NVIDIA, Palo Alto Networks. Private investments include stakes in various pre-IPO tech companies. The portfolio has increasingly tilted toward AI beneficiaries since 2023.
Brad Gerstner is moderately relevant to our approach. His concentration and long-term holding align with our philosophy. His focus on secular winners (AI, cloud) aligns with our AGI thesis. However, he is primarily a growth investor, not a value/downside-protection investor. He does not focus on floor prices or margin of safety in the Buffett sense. His activism edge is interesting -- the Meta letter showed he thinks about capital discipline. But his SPAC activity and willingness to invest at high valuations (Grab at $40B, Snowflake at extreme multiples) shows he is willing to pay up for growth in ways we would not. He is worth following for his AI/tech sector insights and his concentrated, conviction-driven approach, but his risk tolerance is higher than ours.
Australian-born investor, author, and fund manager. Graduated from the University of Queensland with degrees in Law (2001) and Business Management (1999). Began his career as a corporate advisory lawyer specializing in mergers and acquisitions across multiple countries, then served as general counsel at an Australian Stock Exchange-listed company. Worked as an analyst at an activist hedge fund before founding Acquirers Funds LLC, an SEC-registered investment adviser headquartered in Rolling Hills, California. Author of four influential investing books: 'Quantitative Value' (2012, co-authored with Wesley Gray), 'Deep Value' (2014), 'Concentrated Investing' (2016), and 'The Acquirer's Multiple' (2017, #1 new release in Amazon's Business and Finance category). Also created The Acquirer's Mult...
Carlisle's core insight is that 'buying cheap' alone — without quality filters — historically outperforms 'buying cheap-and-quality' (the Greenblatt Magic Formula approach). This was the central thesis of 'Deep Value' and 'The Acquirer's Multiple.' The Acquirer's Multiple is defined as Enterprise Value / Operating Earnings, which he argues is a more robust valuation metric than P/E because it accounts for debt, cash, and is harder to manipulate through accounting tricks. His philosophy draws on mean-reversion: companies that are deeply undervalued and out-of-favor tend to revert toward fair value, often because they attract activist investors, get acquired, or simply recover operationally. He uses quantitative methods to identify these candidates systematically, reducing behavioral biases ...
Runs concentrated, quantitative deep-value portfolios. Manages two primary strategies: a Mid Cap Deep Value Fund and a Small/Micro Cap Deep Value Fund. Typically holds approximately 30 positions in the best deep-value opportunities identified by his quantitative screens. While 30 positions is not extremely concentrated by absolute standards, it is concentrated relative to quantitative value strategies (which often hold 100+ positions). Holdings are rebalanced systematically based on the Acquirer's Multiple ranking — stocks enter when they screen as deeply undervalued and exit when they no longer qualify. This creates natural portfolio turnover. The strategy is long-only, no leverage, no shorting, no derivatives — purely systematic equity selection. Holdings tend to be out-of-favor, beaten-...
Carlisle's published backtests in 'The Acquirer's Multiple' and 'Deep Value' show that the acquirer's multiple strategy outperformed the S&P 500 and Greenblatt's Magic Formula over long historical periods (1973-2017 backtesting). However, live fund performance has been more mixed. His Acquirers Fund (ZIG ETF, later restructured) launched in 2019 but was closed after underperforming during the growth-dominated 2019-2021 period when deep value significantly lagged momentum and growth. The DEEP ETF was also launched as a small/micro-cap deep value product. Quantitative deep value as a strategy suffered a historically bad stretch from roughly 2017-2020, with growth and momentum dramatically outperforming. Since 2022, value has staged a comeback, and Carlisle's strategies have fared better. Ove...
Very high. Carlisle is one of the most transparent investors in the deep-value space. He has written four detailed books explaining his methodology, publishes a free stock screener (Acquirer's Multiple) that anyone can use, hosts a podcast where he discusses his thinking openly, writes regular blog posts, and shares his quantitative research publicly. His investment process is fully systematic and well-documented — unlike discretionary managers, there is no 'black box.' His forensic accounting filters (Beneish, Piotroski, Altman) are published and replicable. He regularly discusses the limitations and drawdowns of his approach honestly, including periods of underperformance. This level of transparency is unusual in the fund management industry.
High. Carlisle is intellectually honest about the challenges of deep-value investing, including periods of significant underperformance. He has been transparent about his funds' difficulties during the growth-dominated market of 2018-2021. He does not oversell his strategy or hide behind cherry-picked timeframes. His books present backtested data with appropriate caveats. He acknowledges the emotional difficulty of holding deeply unpopular stocks and the behavioral challenges this creates for investors. He has been consistent in his philosophy over many years rather than style-drifting to chase performance. His fee structure for the funds is reasonable relative to active management peers. The free screener tool represents genuine value provided to the investing community without direct mon...
Holdings are systematically selected based on the Acquirer's Multiple (EV/Operating Earnings) and rotate regularly. Typical holdings are deeply undervalued, out-of-favor mid-cap and small-cap stocks across diverse sectors. The portfolio does not have permanent 'notable holdings' in the way discretionary managers do — positions enter and exit based on quantitative ranking. Historically, the portfolio has been heavy in sectors like energy, financials, industrials, and materials — sectors that tend to trade at lower valuations. Tech and high-growth stocks are structurally underweight because they rarely screen as deeply cheap on EV/Operating Earnings. This sector tilt is a feature of the methodology, not a deliberate choice.
Moderate relevance. Carlisle's philosophy aligns well with our emphasis on downside protection, contrarian thinking, and buying cheap. His focus on enterprise value rather than just price, and his use of forensic accounting screens to avoid value traps, are directly applicable to our approach. However, there are meaningful differences: (1) His approach is quantitative/systematic rather than fundamental/qualitative — he buys statistical cheapness, not deeply understood businesses. (2) His 30-position portfolio is less concentrated than our ideal. (3) His holding period is tied to rebalancing cycles rather than multi-year conviction. (4) He has no framework for assessing AGI impact or technological disruption — the quantitative approach is sector-agnostic and backward-looking by nature. His ...
Chairman and CIO of GQG Partners, which he founded in 2016 after leaving Vontobel Asset Management where he served as CIO and head of international/emerging market equities. Born in India. Built an exceptional track record at Vontobel over 18 years managing international and emerging market strategies. Left to start GQG with a focus on 'Forward-Looking Quality' investing. GQG Partners went public on the Australian Securities Exchange (ASX:GQG) in 2021. Currently manages approximately $163 billion in AUM as of December 2025 — remarkable growth from zero in 2016. One of the fastest-growing asset managers globally.
Forward-Looking Quality framework. Seeks companies positioned for success over the next 5+ years regardless of traditional growth/value labels. Emphasizes downside risk management — aims to capture upside in rising markets while protecting capital in downturns. Focuses on quality businesses with durable competitive advantages, strong balance sheets, and capable management. Willing to invest across geographies including emerging markets where many managers fear to tread. Contrarian willingness to take positions that look unconventional (e.g., heavily buying Adani stocks after the Hindenburg short report in 2023). Believes in concentrated conviction-weighted portfolios.
Concentrated quality-focused. Manages global equity, international equity, and emerging markets strategies. Typically 30-50 holdings per strategy. Top positions meaningfully sized. Heavy in mega-cap quality names: NVIDIA, Meta, Alphabet, major energy and industrial companies. Notable for large emerging market positions including controversial Adani Group holdings. Higher turnover than typical value investors — willing to reshape portfolio as forward-looking quality assessment changes. Position sizing driven by conviction.
Excellent. At Vontobel (1994-2016), built one of the best track records in international/emerging market investing, significantly outperforming benchmarks over 18 years. At GQG (2016-present), has continued to outperform across all three strategies (global, international, EM). Asset growth from $0 to $163B in 9 years speaks to both performance and institutional confidence. The firm's listing on ASX validates the business model. The Adani bet in 2023, while controversial, has been vindicated so far as Adani stocks recovered significantly. Overall, one of the strongest and most consistent track records in global equity investing.
Moderate-High. As a publicly listed company (ASX:GQG), provides significant corporate disclosure. Publishes quarterly commentary and portfolio holdings. 13F filings for US holdings. However, the investment process itself is somewhat opaque — Jain's 'Forward-Looking Quality' framework is described in general terms but specific analytical methods are proprietary. Jain does give occasional interviews and media appearances. Better transparency than hedge funds but less than the best mutual fund letter-writers.
Generally high, with one notable controversy. The Adani investment in 2023 drew significant scrutiny — GQG invested approximately $1.9B in Adani Group companies shortly after the Hindenburg Research short report alleged fraud. Critics questioned whether this was reckless. Jain defended the position publicly and the investment has performed well. The decision to go against consensus and put his reputation on the line showed conviction, though questions about Adani's governance remain. No regulatory issues or ethical scandals at GQG itself. Employee ownership and public listing create alignment.
NVIDIA, Meta Platforms, Alphabet, Exxon Mobil, Tata Consultancy Services, Adani Group companies (Adani Enterprises, Adani Ports, Adani Green Energy), Petrobras, various Indian and Brazilian companies. Notable for willingness to invest in emerging market companies that many Western managers avoid.
Moderate. Jain's emphasis on quality businesses with durable advantages aligns with our approach. His 5+ year forward-looking horizon matches our long-term orientation. The downside-risk-first mentality is conceptually aligned with our floor-price philosophy. However, his portfolio is more globally diversified than our focus, his turnover is higher, and his willingness to invest in governance-questionable companies (Adani) may not align with our integrity standards. His tech holdings (NVIDIA, Meta, Alphabet) overlap with our universe. The AUM scale ($163B) means he moves markets and may face different constraints than we do.
Loews Corporation is a diversified holding company controlled by the Tisch family, founded by brothers Laurence (Larry) Tisch (1923-2003) and Preston Robert (Bob) Tisch (1926-2005). The brothers built Loews from a single hotel (Loews Hotels) in the 1940s into a conglomerate spanning insurance, energy, hotels, tobacco, broadcasting, and other industries. Larry Tisch was the financial/investment genius while Bob managed operations, particularly the hotel chain. Larry Tisch was known as one of the shrewdest investors on Wall Street -- he took a controlling position in CBS Inc. in 1986, serving as CEO/President until 1995 (a period of controversy), and made prescient investments across many sectors. The Tisch family also co-owned the New York Giants (Bob's son Steve) and had deep involvement i...
The Tisch family's investment philosophy, particularly as practiced by Larry Tisch and continued by Jim Tisch, centers on several principles: (1) Buy assets at significant discounts to intrinsic value -- Larry Tisch was famous for buying when others were panicking. (2) Concentrate in a few large positions -- Loews has typically owned 3-5 major businesses at any time. (3) Be patient -- hold for years or decades, and be willing to wait for the right opportunity. (4) Use a strong balance sheet as a competitive weapon -- Loews has consistently maintained low leverage at the parent level, giving it the ability to act when others are forced sellers. (5) Return capital to shareholders through buybacks when the stock trades below intrinsic value -- Loews has been one of the most aggressive share r...
Loews is a holding company with a very simple, concentrated structure. Current major subsidiaries/investments: (1) CNA Financial Corporation (NYSE: CNA) -- 92% ownership stake in the 7th-largest commercial property and casualty insurer in the US. CNA is by far the largest subsidiary and drives the majority of Loews' value. CNA generates $3-4B in annual premiums and is a solid, if unspectacular, commercial insurer. (2) Boardwalk Pipelines -- a natural gas pipeline and storage company operating ~14,000 miles of pipelines, primarily in the Gulf Coast region. Loews took Boardwalk private in 2018 for $1.5B, buying out minority shareholders at a premium. Boardwalk generates stable, fee-based cash flows. (3) Loews Hotels & Co -- a luxury/upscale hotel chain with ~25 properties. Relatively small c...
Solid but unspectacular in recent decades. Under Larry Tisch (1960s-1990s), the returns were excellent -- he compounded capital at high rates through shrewd acquisitions and contrarian timing. His CBS investment, while operationally controversial (he cut costs and was accused of gutting CBS News), was financially profitable when CBS was sold to Westinghouse/Viacom. The Lorillard ownership was enormously profitable despite being a tobacco company. Under Jim Tisch (1999-present), returns have been decent but below the S&P 500 over most periods. The stock traded around $50-60 in 2000, hit $55 in 2007, fell to $20 in 2009, recovered to $50 in 2014, and trades in the $75-85 range as of 2024-2025. Total returns (including dividends and buyback-driven per-share value growth) have been in the mid-...
Good. As a public company, Loews files standard SEC reports (10-K, 10-Q, proxy statements). Jim Tisch is accessible on quarterly earnings calls, where he discusses capital allocation decisions openly. CNA also files separately as a public company, providing additional visibility. The corporate structure is relatively simple compared to Fairfax or Berkshire -- just 3 major subsidiaries plus corporate cash. Jim Tisch has given interviews and speeches about Loews' investment philosophy. However, Tisch is not known for Buffett-style shareholder letters with deep philosophical discussions. The annual letter is brief and functional. The family's motivations and long-term plans are not always fully communicated. Overall: solid public company disclosure, but not the philosophical transparency of B...
High. The Tisch family has a strong reputation for ethical conduct in business and extensive philanthropic activity. Key positives: (1) Significant personal ownership (30%+ of Loews) ensures alignment with public shareholders. (2) Share buybacks have been consistent and disciplined, focusing on periods when the stock trades below NAV. (3) Jim Tisch takes modest compensation relative to peer CEOs. (4) No accounting scandals, fraud, or ethical controversies. (5) The Diamond Offshore situation, while a financial loss, was handled forthrightly -- Loews let it go through bankruptcy rather than throwing good money after bad. (6) The family's philanthropic involvement (NYU Tisch School of the Arts, Tisch Hospital, numerous other institutions) demonstrates long-term community commitment. Minor neg...
Current: CNA Financial (92% owned, commercial P&C insurance, $3-4B annual premiums), Boardwalk Pipelines (100% owned, natural gas pipelines, taken private 2018), Loews Hotels & Co (100% owned, ~25 luxury/upscale hotels), corporate cash portfolio ($2-4B). Historical: Lorillard Inc. (tobacco, owned until 2008 spinoff, later merged with Reynolds American/BAT), Diamond Offshore Drilling (deepwater drilling, went through bankruptcy 2020), Bulova Watch Company (sold to Citizen 2008), CBS Inc. (Larry Tisch's famous investment, sold to Westinghouse 1995), various other historical investments.
Moderate relevance. Loews' philosophy aligns reasonably well with ours in several key ways: (1) focus on buying below intrinsic value; (2) long-term holding; (3) conservative balance sheet; (4) share buybacks when trading below NAV; (5) concentration in a few major positions; (6) willingness to own unfashionable businesses. Jim Tisch's 'cigar butt' approach and the persistent conglomerate discount make Loews itself a potential investment candidate -- it consistently trades below the sum of its parts, meaning there may be a reliable floor price. However, key limitations: (1) the Tisch family has no engagement with technology or AGI themes -- they invest in insurance, pipelines, and hotels; (2) the track record under Jim Tisch has been merely adequate, not exceptional; (3) the conglomerate d...
Born 1916 in New York City. Did not attend college. Took Benjamin Graham's investment course at the New York Institute of Finance in 1934 and worked directly for Graham at Graham-Newman Corporation from 1934 to 1955 alongside Warren Buffett. After Graham retired and closed the fund, Schloss started his own investment partnership, Walter J. Schloss Associates, in 1955 with $100,000 in capital. His son Edwin joined the firm, and it became Walter & Edwin Schloss Associates. Operated out of a single room, with no computer, no Bloomberg terminal, no analysts — just Value Line sheets and annual reports. Ran the partnership for 47 years until closing in 2002, when Schloss was 85 years old. He was featured by Warren Buffett in the famous 1984 essay 'The Superinvestors of Graham-and-Doddsville' as ...
Walter Schloss was perhaps the most faithful practitioner of Benjamin Graham's original deep-value methodology. His approach was distilled in his famous '16 Factors Needed to Make Money in the Stock Market': (1) Price is the most important factor — buy below value. (2) Try to establish the value of the company by looking at the assets. (3) Use book value as a starting point. (4) Have patience — stocks don't go up immediately. (5) Don't buy on tips or for quick moves. (6) Don't sell on bad news. (7) Don't be afraid to be a loner. (8) Be sure of your reasoning. (9) Have a philosophy and try to follow it. (10) Don't be in too much of a hurry to sell. (11) Buy near the low of the past few years. (12) Buy assets at a discount rather than trying to buy earnings. (13) Listen to suggestions but ma...
Highly diversified — Schloss typically held 80-100+ stocks at any time, sometimes more. Individual position sizes were small, usually 1-3% of the portfolio. He bought stocks across all sectors and industries, with no particular sector expertise. The only common thread was cheapness relative to book value or asset value. He preferred stocks making new lows, trading near multi-year lows, with low price-to-book ratios. He did not use leverage, did not short, and charged very modest fees (no management fee — just 25% of profits above a hurdle rate, later reduced). Turnover was moderate to low — he would hold stocks for 2-4 years on average, waiting for them to return to fair value. He reinvested dividends and compounded capital steadily. The approach was almost the opposite of concentrated, qu...
Outstanding over nearly 5 decades. From 1956 to 2002 (47 years), Walter Schloss Associates compounded at approximately 15.3% per year gross (compared to about 11.5% for the S&P 500 over the same period). An original $1,000 invested in 1955 would have grown to approximately $662,000, compared to about $130,000 for the S&P 500 — roughly 5x better compounding over the full period. He achieved this with only 6 losing years in 47 (a remarkable consistency rate). Net of his modest performance fees (25% of profits), investors still earned well above the market. The partnership had no down year worse than -10%, demonstrating the downside protection inherent in buying diversified baskets of cheap stocks. Buffett featured Schloss in his 'Superinvestors' essay as compelling evidence that value invest...
Medium. Schloss was a private person who ran a small partnership. He did not write extensive investor letters or publish research. His partnership agreements and annual performance figures have been published and verified (including by Buffett). His '16 Factors' list is publicly available. He gave a few interviews later in life (including to Outstanding Investor Digest) where he explained his approach clearly. His method was extremely simple and transparent in the sense that anyone could understand and replicate it — the transparency was in the method rather than in specific position disclosure. After closing the partnership in 2002, the historical record has been well-documented. However, real-time position tracking was never available.
Exceptionally high — among the highest of any documented investor. Schloss charged no management fee for most of his career — only 25% of profits above a hurdle rate. This meant that in years he lost money, he earned nothing. This is the most aligned fee structure possible: he only made money when his investors made money. He invested his own capital alongside partners. He operated from a single room with minimal overhead, never expanding the firm, never hiring analysts, never empire-building. He was described by Buffett and other contemporaries as one of the most honest and humble people in the investment business. He never promoted himself, never appeared on CNBC, never sought publicity. He lived modestly and let his track record speak for itself over nearly 50 years. No scandals, no eth...
Schloss bought what were often called 'cigar butts' — companies that were cheap on a statistical basis but often lacked exciting growth prospects. These included industrial companies, manufacturers, retailers, and financial companies trading below book value. Specific names from various accounts include companies like Southdown (cement), Cleveland-Cliffs, various small banks and insurers, and industrial companies in cyclical downturns. He avoided technology stocks almost entirely because they lacked the tangible book value he used as his primary valuation metric. His portfolio at any given time was a cross-section of the cheapest stocks in America by price-to-book metrics.
Moderate relevance with important caveats. Schloss's philosophy aligns well with our 'floor price' concept — buying below asset value is essentially buying with a high-confidence floor. His obsession with balance sheet cheapness, his refusal to use leverage, and his long-only orientation match our approach. His incredible track record validates the concept that downside protection (buying cheap) leads to good long-term returns. However, several important differences exist: (1) Schloss was maximally diversified (80-100+ stocks), we want concentration. (2) He bought purely on statistical cheapness without understanding the business deeply — we want deep business understanding. (3) He completely ignored business quality, competitive dynamics, and growth potential — we care about these. (4) Hi...
Julian Baker and Felix Baker founded Baker Brothers Advisors in 2000. Julian has a background in finance and previously worked in investment banking and private equity. Felix holds a PhD in immunology from Stanford University, giving the firm genuine scientific expertise in evaluating biotech companies. The firm is based in New York and has grown to manage approximately $20-40 billion in assets (AUM has fluctuated significantly with biotech market cycles). Baker Brothers is widely regarded as one of the most successful biotech-focused investment firms ever, with extraordinary long-term returns. Julian handles the business and investment side while Felix provides deep scientific analysis of drug pipelines and clinical data. The Bakers are among the wealthiest hedge fund managers in the worl...
Baker Brothers takes a fundamentally research-driven, science-first approach to biotech investing. Felix Baker's PhD in immunology allows the firm to independently evaluate clinical trial data, drug mechanisms, and competitive positioning of biotech companies at a level few investment firms can match. The philosophy centers on identifying companies with genuinely differentiated science and strong drug pipelines, then taking large, concentrated, long-duration positions. They are willing to hold positions for many years through clinical development cycles, which can span 5-10+ years. They combine scientific conviction with large position sizes, often becoming one of the largest shareholders in their portfolio companies. The approach is long-biased with high conviction — closer to venture cap...
Highly concentrated — typically 10-20 major positions dominating the portfolio. Extremely long-duration for a biotech fund — they hold positions for years, sometimes a decade or more, through clinical development and commercial launch phases. The portfolio is almost exclusively biotech and pharma, with occasional positions in medtech or diagnostics. They frequently own 5-15% of the companies they invest in, becoming significant shareholders with board-level influence. The portfolio is long-only biased — while they may hedge, the core positions are long, concentrated bets on specific drug pipelines. Position sizes can be enormous — multi-billion dollar stakes in individual companies.
Baker Brothers has one of the best track records in biotech investing history. From 2000 to approximately 2020, the firm generated annualized returns estimated at 20-30%+, dramatically outperforming both the broader market and biotech indices. Their early and large investment in Seattle Genetics (now Seagen) was one of the greatest biotech investments ever made — they were among the largest shareholders for years and the position grew to be worth billions before Pfizer acquired Seagen for $43 billion in 2023. Similarly, their investment in Incyte Corporation was a massive long-term winner, held through the development and approval of Jakafi. However, the firm has also experienced significant drawdowns during biotech bear markets, particularly in 2015-2016 and 2021-2022 when the overall bio...
Moderate. Baker Brothers files quarterly 13F reports showing public equity holdings, which is the primary window into their portfolio. The Bakers themselves are very private — they rarely give interviews, do not speak at conferences, and do not publicize performance numbers. The firm's website is minimal. The 13F filings provide good visibility into their concentrated public positions, but the firm also has private investments not captured in public filings. The SEC settlement in 2023 revealed some trading practices that were not previously known, suggesting less transparency than ideal regarding potential conflicts of interest.
Mixed. On the positive side, the Bakers have built their firm on genuine scientific expertise and long-term conviction investing, which is admirable. They have been significant philanthropists. However, the $200 million SEC settlement in 2023 is a meaningful blemish. The SEC alleged that Baker Brothers made short-term trades in companies where Felix Baker served as a board member, raising concerns about information advantages and conflicts of interest. While the settlement did not involve an admission of wrongdoing (standard in SEC settlements), the size of the penalty ($200M) suggests the regulators viewed the conduct seriously. This is a genuine integrity concern that cannot be dismissed, though it does not appear to involve fraud against investors or fundamental dishonesty in their inve...
Historically, the most notable positions include: Seagen (Seattle Genetics) — held for many years, became a massive winner when Pfizer acquired for $43B; Incyte Corporation — held through the development and commercialization of Jakafi; Acadia Pharmaceuticals; Neurocrine Biosciences; Argenx; Bristol-Myers Squibb (post-Celgene); Ionis Pharmaceuticals. The portfolio typically features mid-to-large cap biotechs with approved or late-stage drugs, plus some earlier-stage positions where the scientific thesis is strong.
Moderate alignment with important caveats. Baker Brothers' concentrated, long-duration, conviction-driven approach is the closest match to our philosophy among healthcare/biotech investors. Their willingness to hold positions for 5-10+ years through development cycles mirrors our patience. The scientific rigor of their analysis is admirable. However, there are significant divergences: (1) biotech investing is inherently speculative — drug development has binary outcomes that create the 'cannot compute floor price' problem in our framework; (2) the SEC settlement raises integrity concerns; (3) biotech companies often have no earnings, no tangible assets, and can go to zero, which conflicts with our 'little chance of losing money' philosophy. Their best ideas in commercial-stage biotech (lik...
Andreas Halvorsen (born 1961 in Norway) co-founded Viking Global Investors in 1999 after working at Tiger Management under Julian Robertson. He served in the Norwegian Navy's special forces (naval commando) before attending Williams College (BA) and the Wharton School (MBA). Viking is based in Greenwich, Connecticut and manages approximately $37.7 billion in 13F-reported assets as of Q4 2025, making it one of the largest and most successful Tiger Cub operations. Halvorsen is known for being extremely disciplined, detail-oriented, and process-driven -- qualities often attributed to his military background. Net worth estimated at $6-8 billion.
Fundamental, research-driven long/short equity investing with a focus on quality businesses with sustainable competitive advantages. Halvorsen's approach: (1) Deep fundamental research -- Viking employs a large research team and is known for exceptionally thorough analysis, (2) Quality bias -- tends to invest in high-quality businesses with strong competitive positions, (3) Long/short equity -- actively shorts overvalued companies alongside long positions, (4) Moderate concentration -- top 10 at 55.9% of portfolio is less concentrated than Tiger Global or Lone Pine, (5) Sector diversification -- broader than pure tech players, with exposure to healthcare, financials, technology, and consumer sectors, (6) Disciplined risk management -- Viking has generally avoided catastrophic drawdowns whi...
Large, moderately concentrated long/short equity portfolio. 76 equity holdings with top 10 representing 55.9% of portfolio. AUM approximately $37.7B (13F), one of the largest hedge funds globally. Diversified across sectors -- technology, healthcare, financials, consumer, industrials. Uses both long and short strategies. The portfolio is more balanced than peers like Tiger Global or Coatue, with broader sector diversification. Turnover is moderate. Q4 2025 performance was +4.94%.
Excellent long-term track record -- one of the best among Tiger Cubs and hedge funds broadly. Viking has delivered estimated 15-20% annualized returns since inception in 1999, with relatively controlled drawdowns compared to peers. The fund navigated 2008 reasonably well and did not suffer the catastrophic 2022 losses that hit Tiger Global. Key strengths: (1) Consistency -- Viking has been consistently profitable over its 25+ year history, (2) Risk-adjusted returns -- better Sharpe ratio than more aggressive Tiger Cubs, (3) Scale -- has maintained strong performance even as AUM grew to $37.7B, which is very difficult. The combination of strong absolute returns, good risk management, and ability to scale makes Viking's track record among the most impressive in the hedge fund industry.
Standard hedge fund transparency through quarterly 13F filings. Viking does not publicly share investor letters or detailed performance data. Halvorsen is very private and rarely gives interviews or public speeches. The fund's large size means its 13F filings provide meaningful insight into portfolio positioning. However, short positions are not disclosed (standard for long/short funds). Overall, compliant but quite private.
Very strong integrity record. No fraud, insider trading, or regulatory scandals in 25+ years. Halvorsen is known for running a disciplined, professional operation. His military background is often cited as contributing to institutional discipline and ethical standards. The fund has grown steadily without controversy. Halvorsen is notably private and avoids the flashy lifestyle associated with some hedge fund managers. Clean record across all dimensions.
As of Q4 2025 (13F), Viking's $37.7B portfolio spans 76 positions across multiple sectors. Historical major holdings have included Visa (V), UnitedHealth Group (UNH), Amazon (AMZN), Microsoft (MSFT), and various large-cap quality companies across healthcare, technology, and financial sectors. The portfolio tends toward large-cap, high-quality businesses with strong competitive positions -- more blue-chip oriented than the growth-at-any-price approach of some Tiger Cubs.
Moderate relevance. Positives: Halvorsen's emphasis on quality businesses with competitive advantages aligns with our interest in fundamentally great companies. His disciplined risk management and avoidance of catastrophic losses resonates with our 'little chance of losing money' philosophy. The focus on deep fundamental research is admirable. Track record is genuinely impressive. Negatives: Long/short approach diverges from our long-only philosophy. Moderate concentration (55.9% in top 10) is less concentrated than we prefer. 76 holdings is more diversified than our ideal. No particular AGI thesis or technology-forward conviction. The fund's size ($37.7B) means it's effectively a large-cap quality fund, which may not offer the asymmetric opportunities we seek.
Egon Durban (b. 1972 in Germany, raised in Brazil and the US) is the co-CEO and managing partner of Silver Lake, the world's largest technology-focused private equity firm with approximately $100+ billion in AUM. After graduating from Georgetown University and the Wharton School (MBA), Durban joined Silver Lake in 1999 as one of its earliest employees, rising to lead the firm alongside Greg Mondre. Silver Lake was founded in 1999 by Jim Davidson, Glenn Hutchins, Roger McNamee, and others, specifically to apply the private equity model to large-cap technology companies — a pioneering concept at the time. Durban has been the primary dealmaker behind many of Silver Lake's most iconic transactions. He is known for his deep relationships with technology CEOs (Michael Dell, Mark Zuckerberg, Jack...
Silver Lake's philosophy under Durban is uniquely positioned between PE and public equity: (1) Technology-only focus — exclusively large-cap technology and technology-enabled companies. Deep sector expertise creates information and relationship advantages. (2) Flexible capital — Silver Lake invests across the capital structure (equity, credit, convertibles) and across deal types (buyouts, take-privates, minority stakes in public companies, growth equity, structured investments). This flexibility allows them to invest in the best risk-adjusted opportunity regardless of structure. (3) Relationship-driven — Durban builds deep, long-term relationships with technology CEOs, becoming a trusted advisor and partner. This yields proprietary deal flow and information advantages. (4) Longer duration ...
Concentrated relative to PE but diversified relative to our approach. Silver Lake typically holds 15-25 companies across its flagship fund, with larger positions than most PE firms (deals typically $1-10B+ in size). The portfolio is exclusively technology and technology-enabled companies, giving it genuine sector concentration. Importantly, Silver Lake's 'crossover' investments include large minority stakes in public companies, meaning their positions are partially visible through public filings and announcements. Recent portfolio themes include: enterprise software, semiconductors, data/analytics, fintech, digital media, gaming, and AI infrastructure. Silver Lake has also expanded into Silver Lake Waterman (smaller deals) and Silver Lake Alpine (credit). The firm's balance of concentrated...
Outstanding. Silver Lake is widely considered the most successful technology-focused PE firm, with flagship fund returns consistently in the top quartile. Key deals: (1) Dell Technologies — the signature deal. Silver Lake partnered with Michael Dell in 2013 to take Dell private for $24.4B, then orchestrated the $67B EMC acquisition (2015-16), and re-IPO'd Dell Technologies in 2018. The combined transaction generated 3-4x returns on equity, producing billions in profit and is considered one of the greatest PE deals ever. (2) Alibaba — Silver Lake invested ~$500M in Alibaba before its 2014 IPO, generating multi-billion-dollar returns. (3) Skype — acquired from eBay in 2009, sold to Microsoft in 2011 for $8.5B, roughly doubling Silver Lake's investment in under 2 years. (4) Broadcom/Avago — i...
Moderate. Silver Lake is private (not publicly listed), so there are no SEC filings for the firm itself. However, Silver Lake is MORE transparent than typical PE in several ways: (1) their public company minority stakes are announced and trackable, (2) take-private transactions require public merger proxy filings with detailed financials, (3) Durban is an active public speaker and sits on multiple public company boards (historically Dell Technologies, Twitter, Endeavor, and others), giving public visibility into his thinking. (4) Silver Lake publishes occasional thought leadership on technology investing. The firm's LP base includes major institutional investors who receive detailed fund reporting. Compared to pure public equity managers with 13F filings, Silver Lake is less transparent, b...
Generally good with some nuances. Positives: (1) Durban has a reputation as a thoughtful, relationship-first dealmaker — technology CEOs actively seek Silver Lake as a partner, which suggests they are seen as trustworthy operators, (2) Silver Lake's longer holding periods and genuine operational involvement suggest alignment rather than pure extraction, (3) the firm has avoided major scandals or SEC enforcement actions, (4) the Dell deal, while controversial at the time (Carl Icahn accused the take-private of undervaluing the company), ultimately created enormous value for all stakeholders including public shareholders who rolled their equity. Nuances: (1) Durban's involvement in the Twitter/X take-private alongside Elon Musk is potentially reputational risk depending on how that investmen...
Current and recent notable holdings include: Dell Technologies (ongoing relationship, though PE position largely exited), Endeavor Group (entertainment/sports), Motorola Solutions (public minority stake), Expedia Group (large minority stake), Qualtrics (acquired alongside SAP take-private), Unity Technologies (gaming engine), SolarWinds (cybersecurity/IT management), Airbnb (pre-IPO investment), Twitter/X (co-invested with Elon Musk, 2022), Relativity (legal tech), Waymo (co-invested), ZoomInfo (data analytics), Sports Illustrated/Authentic Brands (media IP), and significant AI-related investments in infrastructure and semiconductor companies. Silver Lake has been increasingly active in AI-adjacent investments through 2024-2025.
Moderate-to-good relevance — the highest in this PE group. Several factors make Silver Lake/Durban more relevant than typical PE: (1) Technology-only focus aligns with our AGI thesis and technology-forward investment approach, (2) Public market crossover investments (Expedia, Motorola Solutions, Dell, etc.) provide actionable signals for public equity investors, (3) Longer holding periods (5-10+ years for core strategy) are closer to our philosophy, (4) Durban's deep relationships with technology CEOs give him genuine information advantages, making his conviction signals valuable, (5) Silver Lake's history of identifying undervalued technology platforms (Dell at $13/share before take-private, Alibaba pre-IPO) demonstrates real analytical skill in technology valuation. Limitations: still us...
Jake Taylor is the CEO of Farnam Street Investments, a value-oriented investment firm based in Omaha, Nebraska. The firm is named after the street where Berkshire Hathaway's headquarters is located, reflecting its Buffett-inspired philosophical roots. Taylor is the author of 'The Rebel Allocator,' a novel that teaches capital allocation and business principles through storytelling (in the spirit of business parables). He is also a co-host of the popular 'Value: After Hours' podcast alongside Tobias Carlisle (Acquirers Funds) and Bill Brewster. Before founding Farnam Street Investments, he had a background in finance and investment management. He is well-connected in the value investing community, particularly the Omaha/Berkshire ecosystem, and is known for his thoughtful, multi-disciplinar...
Taylor's philosophy is rooted in the Buffett/Munger tradition but incorporates a strong multidisciplinary element. Key tenets: (1) Focus on understanding businesses deeply before investing — he emphasizes business quality over statistical cheapness. (2) Long-term orientation — he thinks in terms of years, not quarters. (3) Circle of competence — only investing in businesses he can truly understand. (4) Capital allocation as the key management skill — his book 'The Rebel Allocator' is specifically about how capital allocation decisions drive long-term value creation. (5) Mental models and multidisciplinary thinking — strongly influenced by Charlie Munger's latticework of mental models approach. (6) Skepticism of complexity — preference for simple, understandable businesses with clear compet...
Farnam Street Investments runs a moderately concentrated, value-oriented strategy. The firm is smaller in AUM (likely in the $50-200M range) and serves high-net-worth clients and small institutions. The portfolio tends to be diversified across 15-25 positions, more diversified than Huber or Sosin but still concentrated relative to index funds. The firm favors quality businesses with durable competitive advantages, good capital allocation, and reasonable valuations. It is long-only, no leverage, no shorting. The portfolio tends to include a mix of large-cap and mid-cap companies across various sectors. Turnover is relatively low, reflecting the long-term orientation.
Farnam Street Investments has been in operation for over a decade. Exact performance numbers are not widely publicized as it is a private firm. The firm's track record is not well-documented publicly. Taylor's reputation is built more on his intellectual contributions (the podcast, the book, his writing) than on publicly verifiable investment returns. His 'Value: After Hours' podcast has become one of the most popular value investing podcasts, which speaks to his analytical ability and communication skills, though podcast quality does not necessarily correlate with investment returns.
Moderate transparency through his public intellectual output but low transparency on specific portfolio details. His 'Value: After Hours' podcast provides regular insights into his thinking about markets, companies, and investing philosophy. His book 'The Rebel Allocator' explains his views on capital allocation. He is active on Twitter/X and engages with the value investing community. However, specific portfolio holdings, performance numbers, and investor letters are not publicly available. He shares frameworks and ideas freely but not positions.
High integrity. Taylor is well-regarded in the value investing community as thoughtful, honest, and genuinely interested in helping others become better investors. His book and podcast are educational in nature rather than promotional. He is based in Omaha, deeply connected to the Berkshire Hathaway ecosystem, and appears to genuinely practice the values he espouses. He does not engage in marketing hype or self-promotion beyond normal business development. His multidisciplinary approach and intellectual curiosity suggest genuine passion for understanding rather than fee extraction.
Specific holdings are not widely publicized. Based on his public commentary and podcast discussions, he tends to favor quality businesses with good capital allocation — companies like Berkshire Hathaway (natural given his Omaha base and philosophy), consumer staples with pricing power, and businesses with high returns on capital. He has discussed companies across various sectors on his podcast. The firm's 13F filings (if above reporting threshold) would provide the most accurate picture, but they are not widely tracked by financial media.
Moderate to high relevance, primarily as a thinking partner rather than someone to clone. Taylor's emphasis on capital allocation, business quality, and long-term thinking aligns with our approach. His podcast provides regular, high-quality discussions of investment ideas and frameworks. His multidisciplinary approach is valuable. However, his portfolio appears to be more diversified than our preferred concentration level, and there is limited information about his actual holdings or returns. His AGI/AI awareness appears limited — he has discussed AI on the podcast but does not appear to incorporate AGI timelines into his investment framework in the systematic way we do.
Peter Lynch (born 1944) managed the Fidelity Magellan Fund from 1977 to 1990, during which he delivered one of the greatest track records in mutual fund history. He turned $18 million in assets into $14 billion while generating 29.2% annualized returns over 13 years, beating the S&P 500 in 11 of those 13 years. A Boston College and Wharton MBA graduate, Lynch joined Fidelity as an intern in 1966 and became a full-time analyst in 1969. After retiring from Magellan at age 46 (to spend more time with family), he became vice chairman of Fidelity and a prolific author and philanthropist. His books 'One Up on Wall Street' (1989), 'Beating the Street' (1993), and 'Learn to Earn' (1995) have educated millions of individual investors. He is one of the most recognized names in investing history.
Lynch's philosophy was practical and accessible, centered on several key ideas: (1) 'Buy what you know' — use your personal experience as a consumer and citizen to identify investment opportunities before Wall Street does; (2) GARP (Growth at a Reasonable Price) — look for companies with strong growth prospects but not overvalued, using the PEG ratio (P/E divided by growth rate; anything below 1.0 is attractive); (3) Stock categorization — classify every stock into one of 6 categories: slow growers, stalwarts, fast growers, cyclicals, turnarounds, and asset plays, then apply appropriate analysis for each; (4) 'Ten-baggers' — seek stocks that can return 10x or more, which requires identifying them early in their growth trajectory; (5) Do your homework — research the company's fundamentals, ...
Extremely diversified — the polar opposite of concentration. At Magellan's peak, Lynch held over 1,400 individual stock positions simultaneously. His approach was to find as many good ideas as possible across every sector, market cap, and geography. He was famous for researching 200+ companies per week, visiting dozens of companies in person, and turning over rocks everywhere. He held small-caps, large-caps, growth stocks, value stocks, cyclicals, and turnarounds simultaneously. His edge was the sheer volume and quality of his research — he simply found more good ideas than anyone else. While this extreme diversification might seem to dilute returns, Lynch's stock-picking skill was so exceptional that even with 1,400 positions, his winners dramatically outweighed his losers.
Lynch's 13-year track record at Magellan (1977-1990) is one of the best in mutual fund history: 29.2% annualized returns, turning $18 million into $14 billion. He beat the S&P 500 in 11 of 13 years. A $10,000 investment when he took over would have grown to approximately $280,000 when he retired. This performance was achieved not through a few concentrated bets but through consistently superior stock selection across thousands of positions. Notable individual wins include Taco Bell (before PepsiCo acquisition), Dunkin' Donuts, The Limited, Fannie Mae, Ford, Philip Morris, and dozens of other multi-baggers. His ability to identify ten-baggers across diverse sectors and market caps was unmatched. The main caveat is that his 13-year tenure, while extraordinary, was shorter than many other leg...
Lynch was extraordinarily transparent about his methods. His three books lay out his entire analytical framework in accessible, practical terms with numerous real-world examples. He was a frequent speaker, TV commentator, and writer who openly shared his investment thinking. Magellan's quarterly reports and Fidelity's disclosures provided visibility into his holdings. Since retirement, he has continued to share his views through occasional interviews and articles. His transparency extended to acknowledging mistakes and explaining what went wrong. The main limitation is that with 1,400+ positions, it was difficult for followers to replicate his approach — the sheer scale of his research was a moat in itself.
Lynch's integrity is well-established. He retired at the peak of his career (age 46) to spend time with family, walking away from what would have been enormous ongoing compensation — a rare display of values over money. He has been a major philanthropist, donating hundreds of millions through the Lynch Foundation to education, hospitals, and religious organizations in Boston. He never sought to monetize his fame through hedge funds, speaking fees, or promotional activities beyond his books. He was honest about the difficulty of stock picking and the mistakes he made. He has been consistently generous with his time for charitable and educational causes. There are no known ethical controversies associated with Lynch.
Taco Bell — one of his most famous ten-baggers, identified through consumer observation. Dunkin' Donuts — classic 'buy what you know' investment. The Limited — Leslie Wexner's retail empire, identified early. Fannie Mae — enormous position that generated massive returns. Ford Motor Company — bought during the 1980s automotive recovery. Philip Morris — consumer staple with pricing power. Chrysler — Lee Iacocca turnaround play. General Electric — stalwart holding. Stop & Shop — supermarket chain, consumer observation pick. Pier 1 Imports — retail turnaround. Lynch's portfolio spanned every sector from autos to fast food to financial services to retail.
Lynch offers important lessons but his approach diverges significantly from ours: (1) His 'buy what you know' insight is valuable for our qualitative analysis framework; (2) His stock categorization system (6 types) provides useful mental models; (3) His PEG ratio is a quick screen we could use; (4) His emphasis on understanding the 'story' behind a stock aligns with our deep-dive approach. However, critical divergences exist: (1) Lynch was maximally diversified (1,400 stocks) versus our extreme concentration; (2) His GARP approach emphasizes growth over downside protection; (3) His holding periods were often shorter than our 5-10 year minimum; (4) His approach requires superhuman research bandwidth that doesn't scale for an individual investor; (5) No AGI awareness (pre-dates the relevant...
David Swensen (1954-2021) was the Chief Investment Officer of Yale University's endowment from 1985 until his death in May 2021. He held a PhD in Economics from Yale, where he studied under James Tobin (Nobel laureate). Before returning to Yale, he worked at Salomon Brothers and Lehman Brothers on Wall Street, where he helped structure the first-ever currency swap transaction. Swensen gave up a far more lucrative Wall Street career to manage Yale's endowment at a fraction of the compensation, driven by a mission to serve the university. He authored two influential books: 'Pioneering Portfolio Management' (2000, for institutional investors) and 'Unconventional Success' (2005, for individual investors). He mentored an entire generation of endowment CIOs -- many of the best-known institutiona...
Swensen developed what became known as 'The Yale Model' or 'The Endowment Model,' which revolutionized institutional investing. Core principles: (1) Heavy allocation to alternative asset classes -- private equity, venture capital, real assets (timber, oil, real estate), hedge funds -- at the expense of traditional stocks and bonds. (2) Equity orientation -- the portfolio maintains a strong equity bias, reflecting the long time horizon of endowments. (3) Exploit illiquidity premium -- because endowments have near-infinite time horizons, they can invest in illiquid assets that offer higher returns as compensation for lock-up periods. (4) Manager selection is paramount -- Swensen believed alpha comes from picking the best managers, and he built deep relationships with top-tier managers, often...
The Yale Model portfolio was radically different from traditional 60/40 stock/bond allocations. Typical Yale allocation (circa 2020): ~23% venture capital, ~17% leveraged buyouts/private equity, ~9% real estate, ~7% natural resources, ~23% absolute return (hedge funds), ~7% domestic equity, ~12% foreign equity, ~4% fixed income/cash. This means roughly 75-80% of the portfolio was in alternative, illiquid assets. The portfolio was broadly diversified across asset classes but highly concentrated in manager selection within each class. Turnover was low at the strategic level -- asset allocation was set for decades, with tactical rebalancing at the margins. This approach required a large, sophisticated in-house team to evaluate and monitor managers.
Exceptional by virtually any measure. Under Swensen's 36-year tenure (1985-2021), Yale's endowment grew from approximately $1 billion to $42.3 billion (at the time of his death). The endowment generated annualized returns of approximately 13.7% over his full tenure, far exceeding the roughly 9-10% return of a traditional 60/40 portfolio over the same period. Yale's endowment was the top-performing large university endowment over almost every meaningful time period. The 20-year annualized return was approximately 11.3% through 2021. The endowment outperformed its benchmark by roughly 3-4% annually over his tenure. Notably, the Yale Model struggled in 2008-2009 (GFC), with a -24.6% return in FY2009, partly because illiquid assets could not be easily sold and the endowment had to issue bonds ...
Moderate transparency. Yale published annual endowment reports with asset allocation, returns, and spending data. Swensen's two books laid out his investment philosophy in detail, which is unusual for an institutional investor. He was willing to speak at conferences and in interviews about his approach. However, specific manager names, position-level detail, and internal deliberations were not disclosed. As a university endowment, Yale was not subject to SEC disclosure requirements (no 13F filings). His book 'Pioneering Portfolio Management' was the definitive text on the endowment model and remains required reading for institutional investors.
Exceptionally high. Swensen chose to work for Yale at a fraction of what he could have earned on Wall Street (estimated $5-10M/year vs. potentially $50-100M+ in the private sector) because he believed in the university's mission. He was deeply committed to intellectual honesty and frequently warned individual investors NOT to try to replicate the endowment model (recommending index funds instead). He was critical of the mutual fund industry for excessive fees and poor investor outcomes. His mentorship of dozens of investment professionals who went on to run other endowments reflects his commitment to the field beyond personal enrichment. No scandals, no self-dealing, no conflicts of interest. He continued working through his cancer treatment until close to his death. He is universally resp...
As an asset-allocation-focused endowment, Yale did not hold individual stocks in the traditional sense. Instead, its 'holdings' were allocations to top-tier managers: early and large commitments to venture capital (Sequoia, Greylock, etc.), private equity firms (Clayton Dubilier & Rice, Lone Star, etc.), hedge funds (Farallon Capital, etc.), and real asset managers. Yale was an early investor in many of the most successful VC and PE funds, and its track record in venture capital was particularly outstanding. The endowment also held timber and oil/gas assets directly.
Moderate relevance despite very different portfolio construction. Swensen's philosophy shares some deep similarities with ours: (1) Long-term orientation -- endowments invest with a perpetual time horizon, which aligns with our 5-10+ year holding period. (2) Emphasis on quality of partners/managers -- this is analogous to our focus on management quality. (3) Contrarian rebalancing -- buying when others sell is consistent with our floor-price approach. (4) Intellectual rigor and honesty about what works for different types of investors. However, the differences are substantial: Swensen's approach is fundamentally about asset allocation and diversification across dozens of managers and asset classes, while we run a concentrated, single-stock portfolio. He did not do individual stock analysis...
Harris Kupperman, widely known as 'Kuppy,' is the founder and Chief Investment Officer of Praetorian Capital, a hedge fund focused on special situations, macro themes, and deep value opportunities. He is also well known for his popular investment blog 'Adventures in Capitalism' (adventuresincapitalism.com), where he shares detailed investment theses and market commentary. Kupperman has an unconventional background: he spent years living and investing in Mongolia and other frontier markets before returning to manage Praetorian Capital in the US. He has experience across energy, shipping, uranium, real estate, and various special situations globally. Kupperman is known for making large, concentrated bets on out-of-favor sectors and situations where he identifies asymmetric risk/reward. He is...
Kupperman's philosophy blends deep value, macro thematic investing, and special situations. Key principles: (1) Seeks 'Event-Driven Acceleration' - situations where a catalyst will unlock value that the market is ignoring or discounting; (2) Heavy emphasis on asymmetric risk/reward - willing to invest in deeply out-of-favor sectors when downside is limited but upside is potentially enormous; (3) Macro-informed stock picking - uses macro analysis (inflation, interest rates, commodity cycles, geopolitics) to identify which sectors and themes will benefit, then finds individual securities within those themes; (4) Concentrated portfolio with high-conviction bets - willing to put significant capital into his best ideas; (5) Willing to invest in frontier and emerging markets (Mongolia, Africa, e...
Concentrated and thematic. Praetorian Capital typically holds 15-25 positions across several macro themes. Themes have included: shipping (dry bulk, tankers), uranium, energy (oil and gas producers), real estate, and various special situations. The portfolio is long-biased but may use some hedging. Position sizing reflects conviction level, with largest positions representing significant portfolio weight. Kupperman is willing to hold positions for years when the thesis is playing out, but will also trade actively around core positions. He invests globally, including in frontier markets that most funds ignore. The fund is relatively small (estimated AUM in the low hundreds of millions), which allows him to invest in smaller, illiquid opportunities that larger funds cannot access.
Kupperman has generated strong returns, particularly during the 2020-2024 period when his macro themes of inflation, commodity shortages, and shipping played out. He was notably early and correct on several major calls: (1) Bullish on shipping/dry bulk in 2020-2021 when the sector was deeply out of favor, generating outsized returns as freight rates surged; (2) Early bull on uranium before the 2021-2024 rally; (3) Correctly positioned for the inflation surge in 2021-2022; (4) Profitable in various frontier market special situations. However, being early on themes has also meant enduring painful drawdowns before catalysts materialized. His Mongolia investments were a multi-year patience test. The blog provides a partial track record of his public calls, which have been generally strong on t...
Very high. Kupperman is one of the most transparent hedge fund managers operating today. His 'Adventures in Capitalism' blog provides detailed write-ups of investment theses, often sharing the full analytical framework behind his positions. He is extremely active on Twitter/X, sharing real-time market commentary and position updates. He regularly appears on podcasts and investment conferences. He discusses both his wins and losses publicly. His blog posts often include specific position sizing, entry/exit points, and thesis updates. While exact fund performance is not disclosed, his public communications provide significant insight into his thinking and positioning. This level of transparency is rare among hedge fund managers.
Moderate-to-high. Kupperman is intellectually honest and willing to discuss mistakes publicly. He eats his own cooking with significant personal capital in Praetorian Capital. He does not appear to engage in the pump-and-dump behavior that plagues some public-facing investors. However, his Twitter presence can be promotional, and he sometimes takes a strongly bullish tone on positions he holds, which creates potential conflicts of interest. His frontier market investing (particularly Mongolia) raised some eyebrows but appears to have been genuine value investing rather than anything improper. He is known for having strong opinions and expressing them forcefully, which some view as intellectual honesty and others as promotional behavior. No known regulatory issues or ethical violations.
Based on public blog posts and commentary, notable positions have included: Shipping companies (Star Bulk Carriers, Golden Ocean, Genco Shipping during dry bulk bull thesis), Uranium miners (Cameco, various junior uranium developers during uranium bull thesis), Oil and gas producers (various E&P companies during energy bull thesis), Mongolia-focused companies (Mongolian Growth Group, SouthGobi Resources during his frontier market period), Real estate companies (various), Inflation beneficiaries (commodity producers, real asset companies). His position mix changes significantly over time as macro themes evolve. He has also been involved in activist situations at smaller companies.
Moderate relevance. Kupperman's willingness to make concentrated, contrarian bets on deeply unfashionable situations aligns with our approach. His emphasis on asymmetric risk/reward and downside protection through buying at depressed valuations resonates with our floor-price methodology. His transparency through the blog makes his thinking accessible. However, several factors limit relevance: (1) His trading orientation and willingness to actively manage positions differs from our buy-and-hold preference; (2) His macro-driven approach means positions change as themes evolve, unlike our desired permanence; (3) His focus on commodities and shipping may not align with our AGI thesis; (4) His hedge fund structure means his actual portfolio may differ from public commentary. The blog is worth r...
Anthony Bolton (born 1950) is a British investor widely regarded as one of the UK's greatest fund managers. He managed the Fidelity Special Situations Fund from 1979 to 2007, delivering approximately 19.5% annualized returns over 28 years — turning GBP 1,000 into over GBP 147,000. He outperformed the FTSE All-Share by roughly 6% per year over nearly three decades. After retiring in 2007, he came out of retirement in 2010 to manage the Fidelity China Special Situations Fund, which performed poorly — losing roughly 30% in its first two years and underperforming the Hang Seng significantly. He retired again in 2014. He authored 'Investing Against the Tide' (2009), sharing his investment principles. Bolton is considered the 'Peter Lynch of the UK' for his exceptional long-term record in UK equ...
Bolton was a classic contrarian value investor focused on UK small and mid-cap equities. His approach emphasized: (1) Finding unloved, overlooked companies trading below intrinsic value; (2) Deep fundamental analysis with particular attention to management quality — he would visit companies extensively and assess CEO character; (3) Contrarian thinking — buying when sentiment was worst; (4) Focus on catalysts for value realization (management changes, restructuring, hidden assets); (5) Willingness to invest in turnaround situations that most avoided; (6) Multi-factor analysis combining quantitative screens with qualitative judgment; (7) Valuation discipline — using normalized earnings and asset values as a floor. He emphasized that understanding the business and its management was more impo...
Bolton ran a relatively diversified portfolio by value investing standards, typically holding 100-150 positions, though his top 20 holdings would represent meaningful concentration. He was primarily focused on UK equities, with emphasis on small and mid-cap stocks where informational advantages were greatest. Turnover was moderate — he would hold core positions for years but actively manage position sizing around conviction levels. He was willing to invest across all sectors and market capitalizations. His China fund marked a significant departure — investing in Chinese equities, a market where his UK-honed skills in management assessment and contrarian value proved far less effective due to different corporate governance standards and market dynamics.
UK period (1979-2007): One of the best long-term track records in European fund management. ~19.5% annualized returns over 28 years, roughly tripling the FTSE All-Share return. He navigated the 1987 crash, the early 1990s recession, the dot-com bubble and bust, all while compounding at exceptional rates. China period (2010-2014): A notable failure. The Fidelity China Special Situations fund underperformed significantly, losing roughly 30% in its first couple of years before a partial recovery. Bolton admitted that his approach — particularly reliance on meeting management — did not translate well to China, where corporate governance and accounting transparency were weaker. The China episode, while damaging to his legacy, was a relatively small portion of his career. Overall career: excepti...
Moderate transparency. Bolton published 'Investing Against the Tide' which provides genuine insight into his investment process, mistakes, and thinking. He was relatively open in media appearances about his approach and reasoning. However, as a fund manager at Fidelity, detailed position-level transparency was limited to regulatory filings. He was candid about the China failure, which speaks well of his intellectual honesty. Post-retirement, he has been thoughtful in sharing lessons learned.
High integrity. Bolton's track record was earned over 28 years with consistent application of his principles. He did not engage in self-promotion or hype. He was honest about the China failure and did not make excuses. He earned his returns through genuine skill and hard work, not leverage or style drift. His fee structure at Fidelity was standard institutional — not extractive by the standards of the era. He returned to investing (China fund) out of genuine intellectual curiosity, not greed. No scandals or ethical issues associated with his career. He is widely respected in the UK investment community for his character and honesty.
During his UK career, Bolton was known for investing in companies like: Man Group, Northern Rock (before the crisis — he exited before the collapse), various UK industrials and financials that were out of favor. He favored turnaround situations in UK small/mid-caps. In China: invested in H-shares and Chinese A-shares, including financial companies and consumer businesses. Specific holdings are less well-documented than US-based investors because UK regulatory disclosure requirements differ from SEC 13F filings.
Bolton's approach has meaningful overlap with our philosophy: contrarian value investing, focus on downside protection through valuation discipline, emphasis on management quality, and long-term orientation. His emphasis on finding 'hidden value' in overlooked companies aligns with our floor price methodology. However, several differences reduce relevance: (1) His portfolio was more diversified (100+ positions) vs our concentrated approach; (2) His focus was UK small/mid-caps, a different universe from our global focus; (3) He is retired and no longer generating new ideas; (4) No indication of thinking about AGI or technological disruption as a core thesis element. The China episode is a useful cautionary tale about circle of competence. His intellectual honesty and process discipline are ...
NOTE: The original assignment listed 'Sagar Singh Setia' as the manager of SRS Investment Management. Research indicates the actual founder and managing partner is Karthik Sarma. No prominent investor named 'Sagar Singh Setia' could be found in public records. This analysis covers Karthik Sarma / SRS Investment Management. Karthik Sarma is the founder and managing partner of SRS Investment Management, a New York-based hedge fund he founded in 2006. Before founding SRS, he worked at Goldman Sachs in the Special Situations Group and at The Baupost Group (Seth Klarman's legendary value fund). He holds degrees from the Indian Institutes of Technology (IIT) and Harvard Business School. SRS Investment Management manages approximately $9.5 billion in AUM as of recent 13F filings. The fund is know...
Sarma's philosophy combines deep fundamental research with extreme concentration. His key principles: (1) Extreme concentration -- he believes that the best risk management is knowing your companies deeply rather than diversifying broadly. With 95% in top 10 positions, he is one of the most concentrated large fund managers; (2) Long-term orientation -- positions are held for years, not quarters, reflecting deep conviction and willingness to ride through volatility; (3) Fundamental value with a growth tilt -- influenced by his time at Baupost (value) and Goldman (special situations), he looks for businesses with strong fundamentals and growth potential at reasonable valuations; (4) Sector expertise -- he concentrates in sectors he knows deeply (consumer, travel, technology) rather than atte...
Extremely concentrated. Top 10 holdings represent approximately 95.5% of the portfolio -- one of the highest concentration levels among major hedge funds. Total positions: approximately 31 equities with no options trades (clean, equity-only structure). AUM of ~$9.5 billion makes this one of the larger concentrated equity funds. Sector allocation is heavily weighted toward consumer/travel, technology, and platform businesses. The portfolio is long-only in practice (or heavily long-biased), based on 13F data showing minimal options activity. Holding periods appear long -- positions are maintained for multiple years. The fund structure is a private hedge fund (LP) with undisclosed fee terms but likely standard hedge fund fees (2/20 or similar). Portfolio turnover appears low, consistent with ...
Mixed recent performance. Q4 2025 showed a -7.74% return, underperforming the S&P 500 in that quarter. However, the fund has been operating since 2006 (~19 years), and its long-term track record with extreme concentration and large AUM suggests institutional credibility and generally strong historical performance -- funds that consistently underperform do not grow to $9.5B AUM. Specific long-term CAGR figures are not publicly available, as SRS is a private hedge fund. His background at Baupost and Goldman provides strong pedigree. The extreme concentration means returns are inherently more volatile -- big winners drive enormous performance, but concentrated losers can cause significant drawdowns. Without detailed long-term performance data, the track record score must reflect this uncertai...
Low. SRS Investment Management files quarterly 13F reports, providing visibility into long equity positions. However, beyond regulatory filings, the fund is extremely private. Sarma does not publish investor letters publicly, does not blog, rarely gives interviews, and maintains minimal media presence. He does not have a public Twitter/X account sharing investment views. Fee structure, performance data, and detailed investment rationale are available only to LPs. This is one of the least transparent major hedge funds relative to its size. For our purposes, the 13F filings provide useful position data, but we have limited ability to understand his reasoning or learn from his thinking.
Appears solid based on limited available information. His training at Baupost (Seth Klarman's fund, known for extreme integrity) and Goldman Special Situations suggests strong professional formation. He has operated SRS for ~19 years without any publicly known regulatory issues, fraud allegations, or ethical controversies. The fund's growth from startup to $9.5B AUM suggests investor satisfaction and trust. However, the extreme privacy makes it difficult to assess integrity deeply -- we simply have less information to evaluate. The clean portfolio structure (equities only, no complex derivatives) is a positive signal.
Based on 13F filings, top positions have included: Uber Technologies (historically one of the largest positions), DraftKings, Marriott International, and various travel/leisure and consumer technology companies. The portfolio reflects deep conviction in platform businesses with network effects (Uber, DraftKings) and consumer/travel recovery themes (Marriott). The extreme concentration (95% in top 10) means the fund's performance is essentially determined by a handful of positions. These tend to be mid-to-large cap companies with strong competitive positions in their respective markets.
Karthik Sarma / SRS Investment Management is moderately relevant to us. The extreme concentration (95% in top 10) is very well aligned with our preference for few, high-conviction positions. The long holding periods align with our 5-10+ year horizon. The focus on platform businesses with network effects and competitive moats resonates with our emphasis on great businesses with secular tailwinds. His Baupost background suggests value discipline in his DNA. HOWEVER, there are notable gaps: (1) his technology focus appears more consumer/travel oriented than AI/AGI focused -- his portfolio does not suggest deep AGI awareness; (2) the fund's extreme privacy means we cannot learn from his thinking the way we can from more transparent investors; (3) the -7.74% Q4 2025 return during a generally po...
Born 1971. MBA from Columbia Business School. Worked at Progressive Insurance in finance, then at private equity and hedge fund roles before founding Castle Point Capital in 2005. Joined Berkshire Hathaway in 2010 as the first of Buffett's two investment managers. Also serves as CEO of GEICO (since 2020), making him both an operating executive and investment manager. Manages roughly $15-20B of Berkshire's equity portfolio. Known for being deeply analytical and process-driven.
Value-oriented with a willingness to look at non-traditional value areas including fintech, emerging markets, and technology. Influenced by Buffett but has a somewhat different style -- more willing to pay up for growth and more interested in newer business models. Has been described as a 'modern Buffett' in his willingness to look at businesses Buffett might not understand as deeply. Believes in thorough research and long holding periods but has shown somewhat more turnover than Buffett.
Moderately concentrated. Positions attributed to him at Berkshire include StoneCo, Nu Holdings (Nubank), Snowflake (since sold), T-Mobile, and various other names. More diversified than Li Lu or Pabrai. Willing to look globally (Brazilian fintech, etc.). His GEICO operating role gives him deep insurance industry knowledge. Some of his picks have been criticized for underperformance (StoneCo, Snowflake bought at IPO).
Mixed at Berkshire. Castle Point Capital had a short track record (2005-2010) during a difficult period (GFC) but reportedly performed reasonably well. At Berkshire, some of his attributed picks have struggled -- StoneCo fell significantly after purchase, Snowflake was bought at a rich IPO valuation and later sold at a loss. However, some picks have done well and exact attribution is speculative. GEICO's operational turnaround under his leadership has been impressive, suggesting strong business acumen even if stock-picking has been inconsistent. Overall track record is harder to assess than Weschler's or Pabrai's.
Low. Like Weschler, his positions are embedded in Berkshire's 13F. Even less public presence than Weschler. Rarely speaks publicly or gives interviews. His GEICO role is more visible operationally. Attribution of specific Berkshire stock picks to him vs Weschler vs Buffett is largely speculative.
High. Selected by Buffett after extensive vetting. No scandals or controversies. His willingness to take on the GEICO CEO role in addition to investment duties shows commitment. Trusted by Buffett with both capital allocation and operating responsibilities.
Attributed positions: StoneCo, Nu Holdings (Nubank), T-Mobile, previously Snowflake, various financial services companies. Also involved in Berkshire's private deal-making and operational oversight.
Moderate. His philosophy has some alignment with ours but he appears more willing to pay high multiples for growth (Snowflake at IPO) which conflicts with our downside-first approach. His fintech and emerging market interests could provide useful idea generation. However, low transparency and mixed public track record limit his utility as someone to follow closely. Better as a secondary reference.
Tweedy, Browne Company is a legendary value investing firm founded in 1920 in New York City. The firm has one of the longest and most distinguished histories in value investing, rooted directly in the Benjamin Graham tradition. The original Tweedy & Company was the brokerage firm that executed trades for Ben Graham and his partnership -- they literally sat across the street from Graham-Newman Corporation. Bill Tweedy founded the brokerage in 1920, and it evolved into an investment management firm through partnerships with Tom Knapp (a student of Ben Graham at Columbia), Ed Anderson, Joe Reilly, and Chris Browne. Chris Browne (who passed away in 2009) was the most prominent partner and author of 'The Little Book of Value Investing.' The current managing directors include Will Browne, Tom Sh...
Tweedy Browne's philosophy is pure Ben Graham value investing, updated for a global context. Core principles: (1) Buy stocks trading at a substantial discount to intrinsic value, determined through rigorous fundamental analysis of assets, earnings power, and private market value; (2) Margin of safety is paramount -- they want a significant cushion between purchase price and estimated value to protect against errors in analysis or unforeseen events; (3) Diversified globally -- they invest across developed markets worldwide, exploiting the fact that value opportunities exist everywhere and are often more abundant outside the US; (4) Currency hedging -- uniquely among value managers, Tweedy Browne hedges foreign currency exposure back to the US dollar, arguing that currency fluctuations add n...
Broadly diversified by individual investor standards but concentrated relative to passive indices. The Global Value Fund typically holds 60-80 positions across 15-20 countries. The top 10 positions represent approximately 25-35% of assets -- less concentrated than most investors on this list. Geographic allocation is heavily tilted toward Europe (40-60% historically), UK (10-15%), with the US representing only 10-25% of the portfolio. Asian and other markets make up the remainder. Sector allocation varies but has historically been weighted toward industrials, consumer staples, financials, and healthcare -- traditional value sectors. Long-only, no leverage, no shorting. Very low turnover -- positions are held for many years, often a decade or more. The firm hedges foreign currency exposure,...
Solid long-term track record, particularly for risk-adjusted returns. The Tweedy Browne Global Value Fund has returned approximately 8-9% annualized since inception in 1993, which is competitive with international value benchmarks and has outperformed many international indices over the full period. However, it has modestly underperformed the S&P 500 over the same period, partly because the US market has dramatically outperformed international markets since 2008 and Tweedy Browne is predominantly international. The currency hedging has been a net positive in periods of dollar strength (2014-2025) but a drag in periods of dollar weakness. Risk-adjusted performance (Sharpe ratio) has been strong relative to peers. Key strengths: consistent, steady returns with lower volatility than the marke...
High transparency. As mutual fund managers, Tweedy Browne files regular holdings disclosures, publishes semi-annual and annual reports, and maintains a public website with extensive educational materials. The firm publishes regular shareholder letters that are well-written and intellectually rigorous, though less frequent than some peers. The 'What Has Worked in Investing' paper (updated periodically) is freely available and widely shared -- it demonstrates the firm's commitment to educating investors rather than marketing to them. The managing directors are accessible through the firm's annual shareholder meeting and occasional media appearances. Fee structure is transparent (expense ratio approximately 1.36% for Global Value Fund, which is somewhat high but has been declining). The firm ...
Very high integrity. Tweedy Browne has operated with impeccable ethical standards for over 100 years. The firm is closely held by its managing directors, who have significant personal capital invested in the funds. No ethical scandals, fraud, or regulatory issues in the firm's 100+ year history. The managing directors are known for their intellectual humility, willingness to admit mistakes, and commitment to the Graham value investing tradition. Chris Browne (who passed away in 2009) was a beloved figure in the value investing community, known for his generosity, honesty, and commitment to teaching value investing principles. The firm has maintained its disciplined approach through multiple market cycles, never chasing trends or deviating from its core philosophy. The location in New York ...
Tweedy Browne's portfolio is global and diversified. Typical holdings include European industrial conglomerates (Safran, Buzzi, CNH Industrial, GlaxoSmithKline, Diageo, Unilever, Novartis, Roche, Henkel, Trelleborg), UK financial companies, Japanese value stocks, Swiss multinationals, and occasional US holdings (Berkshire Hathaway, Johnson & Johnson, Cisco). The portfolio reflects a deep-value, international orientation with a preference for established, dividend-paying businesses with tangible asset backing. They tend to own many European 'hidden champions' -- well-run industrial and consumer companies that are less followed by US investors.
Tweedy Browne has moderate relevance to our approach. Their margin-of-safety-first philosophy and focus on downside protection directly aligns with our 'little chance of losing money' principle. Their long holding periods and low turnover match our approach. Their intellectual rigor and the 'What Has Worked in Investing' paper provide a strong empirical foundation for value investing. However, key differences reduce relevance: (1) they are broadly diversified (60-80 positions) rather than concentrated -- this is the opposite of our preference; (2) they are predominantly international, while our initial focus is US-centric; (3) their traditional deep value approach (low P/B, low P/E, tangible assets) does not capture the growth-oriented value approach we prefer; (4) they have essentially ze...
Dan Sundheim is the founder and CIO of D1 Capital Partners, a public-private crossover investment firm he founded in 2018 with approximately $5B in initial capital. Before founding D1, Sundheim was the Chief Investment Officer at Viking Global Investors, one of the most successful long-short equity hedge funds in history, founded by Andreas Halvorsen (a protege of Julian Robertson at Tiger Management). Sundheim joined Viking in 2003 and rose to CIO, overseeing ~$30B in assets. At Viking, he built a reputation as one of the best fundamental analysts and stock pickers in the hedge fund industry, with a particular focus on technology and consumer companies. D1 Capital manages approximately $20-25B in AUM as of 2024-2025, with a roughly 70/30 split between public equities and private investmen...
Sundheim is a fundamental, research-intensive investor who combines deep bottom-up analysis with sector expertise, particularly in technology, consumer internet, and healthcare. He runs a long-short equity strategy in public markets and a long-only venture/growth equity book in private markets. His approach emphasizes: (1) deep primary research -- D1 is known for extensive expert network calls, channel checks, and data analysis; (2) high-conviction positions -- top ideas receive large allocations; (3) multi-year holding periods for winners, but willingness to cut losers quickly; (4) he thinks about 'normalized earnings power' 2-3 years out and invests where the market underestimates the durability of growth. He bridges value and growth -- he cares about valuation relative to growth, not ju...
D1's public portfolio is diversified but tilted toward high-quality growth companies. The 13F typically shows 50-80 positions, with the top 10 representing 40-55% of assets. Major sectors: technology (30-40%), consumer discretionary (15-20%), healthcare (15-20%), financials (10-15%). He runs moderate net long exposure (typically 60-80% net long). The private portfolio includes pre-IPO stakes in companies like SpaceX, Stripe, Instacart, and other venture-backed tech companies. He is a 'crossover' investor -- investing in companies both pre- and post-IPO. Turnover is moderate -- he holds core positions for years but actively manages risk around them.
Strong overall track record with notable volatility. At Viking Global, Sundheim compiled one of the best track records among Tiger Cubs, contributing to Viking's ~20%+ annualized returns. D1 Capital has had a more mixed but still strong record: 2019 was strong (estimated +25-30%), 2020 was strong (+30%+), but January 2021 saw significant losses (~20% drawdown in one month) due to the GameStop/meme stock short squeeze -- D1 had short positions in several heavily-shorted stocks that squeezed violently. D1 recovered during 2021 but ended the year roughly flat. 2022 was difficult (estimated -20-25% in the public book, offset partially by private holdings). 2023 saw a strong recovery (+20%+ estimated). 2024 was strong (+20%+ estimated). The GameStop episode was a defining moment -- it showed th...
Low transparency, typical of private hedge funds. D1 files quarterly 13F reports (public equity holdings only), but detailed performance data, private portfolio holdings, and short positions are not publicly disclosed. Sundheim rarely gives public interviews or speeches. He does not publish investor letters publicly. He is considered a 'quiet operator' -- highly respected in the hedge fund industry but largely unknown to retail investors. Investors receive quarterly letters, but these are confidential.
High integrity. Sundheim is widely respected in the institutional investment community for his intellectual honesty, humility, and willingness to admit mistakes. After the GameStop losses, he reportedly communicated transparently with investors and made adjustments to risk management. He has not been involved in any fraud, insider trading, or ethical scandals. He left Viking on good terms (a rarity in the hedge fund world) and Halvorsen invested in D1. He is known for building a strong culture at D1 focused on meritocracy and intellectual debate. His fee structure is standard for hedge funds (2/20) but he is not a fee-extracting marketeer -- his funds are largely closed to new capital.
Public: Microsoft, Amazon, Meta Platforms, Alphabet, NVIDIA, Uber, Netflix, Booking Holdings, Datadog, Crowdstrike, Spotify, DoorDash. Private: SpaceX, Stripe (pre-IPO), Instacart, Discord, Figma (prior to Adobe deal collapse). The portfolio reflects a 'best of breed' approach -- owning the dominant companies in large, growing markets.
Moderate relevance. Sundheim's fundamental, research-intensive approach and focus on normalized earnings power resonate with our philosophy. His emphasis on 'best of breed' companies in growing markets aligns with our secular tailwinds preference. However, key divergences: (1) he runs long-short, we are long-only; (2) his fund structure (hedge fund with leverage and shorting) introduces risks we avoid; (3) he is more diversified than our ideal concentration; (4) his private market investments are inaccessible to us. His track record demonstrates genuine analytical skill, and his holdings list is useful as a source of ideas. His Tiger Cub pedigree ensures rigorous fundamental analysis. He is worth following for idea generation and as a quality filter for tech/consumer names, even though his...
Born 1947 in Philadelphia. BA from Yale, MBA from Harvard Business School. Worked at Lehman Brothers, becoming a managing director at age 31. Co-founded Blackstone in 1985 with Pete Peterson using $400,000 in seed capital. Built Blackstone into the world's largest alternative asset manager with over $1 trillion in AUM (as of late 2024). Blackstone went public in 2007 (NYSE: BX). The firm manages assets across private equity ($169B), real estate ($319B investor capital, $611B portfolio value), credit/insurance, and hedge fund solutions. Schwarzman has been a key political figure, serving as chair of Trump's Strategic and Policy Forum (resigned after Charlottesville) and maintaining relationships across political spectrum. He donated $150M to Yale, $350M to MIT for a computing college, and h...
Schwarzman's investment philosophy at Blackstone centers on three principles: (1) 'Don't lose money' — capital preservation is the first rule. He has stated that 'the best way to make money is to not lose it' and that 'every deal should be approached as if it's the only one you'll ever do.' (2) Scale advantage — Blackstone's size enables access to deals, information, and operational resources that smaller firms cannot match. (3) Thematic investing — identify large secular trends and deploy capital at scale behind them. Current themes: AI/data center infrastructure (Blackstone claims to be the world's largest data center owner/developer), logistics/warehousing (e-commerce tailwind), rental housing, and life sciences. (4) Operational improvement — Blackstone's portfolio operations team drive...
Massively diversified across alternative asset classes, but with concentrated thematic bets within each strategy. Blackstone's $1T+ AUM spans: private equity (97 portfolio companies), real estate ($611B portfolio), credit/insurance (~$350B+), and hedge fund solutions. Within real estate, Blackstone has made concentrated bets on logistics/warehousing (largest private warehouse owner globally), data centers (largest data center provider globally, including QTS Realty acquisition for $10B in 2021), rental housing, and hospitality (Hilton buyout in 2007 for $26B, later taken public for huge gains). The firm uses leverage extensively in deals — standard 50-70% LTV in real estate. Schwarzman personally holds a ~20% stake in BX (worth ~$20B+), so his personal wealth is highly concentrated in Blac...
Outstanding institutional track record. Blackstone's flagship real estate fund (BREP series) has generated ~16% net IRR since inception (1991). The Hilton buyout ($26B in 2007) is considered the most profitable private equity deal in history — Blackstone ultimately earned ~$14B in profit, a 3x+ return on a deal executed at the market peak. Private equity funds have historically delivered 2x+ net MOIC. BX stock has been a massive outperformer since IPO ($31 in 2007, now ~$170+ adjusted for splits). Real estate has been the consistent standout: Blackstone's real estate portfolio has generated above-market returns over 30+ years. Challenges: BREIT (retail non-traded REIT) faced massive redemption requests in 2022-2023, requiring redemption caps — reputational damage though no actual value des...
Low-medium for the firm, medium-high for Schwarzman personally. Blackstone is a public company (BX) with full SEC disclosure of financial results, AUM, fee income, and realizations. However, the underlying portfolio company performance is disclosed in aggregate, not deal-by-deal. Fund returns are reported to LPs but not publicly in detail. BREIT and BXMT have public disclosure as registered vehicles. Schwarzman himself gives regular interviews, published a book ('What It Takes,' 2019), and shares his views on markets and leadership. His macro views and thematic positioning are well-telegraphed. But the specific deal-level returns and decision-making process are institutional and not available to outside observers.
Mixed assessment. On the positive side: Schwarzman has built a world-class institution with a strong culture of risk management. He has been a massive philanthropist ($150M to Yale, $350M to MIT, $100M to Schwarzman Scholars program in China). The firm has generally treated investors well and delivered strong returns. On the negative side: The fee structure at Blackstone is extremely lucrative for the GP — Schwarzman personally earns $800M-$1B+ annually through management fees and carry. The 2007 IPO was criticized as Schwarzman monetizing at the top. BREIT's structure (selling illiquid real estate to retail investors with limited redemption rights) raised ethical questions when redemption gates were activated. The firm's political connections and lobbying (carried interest tax treatment, ...
Blackstone's key portfolio positions include: Data Centers — QTS Realty ($10B acquisition 2021, now a major AI infrastructure platform, largest data center portfolio globally), developing $70B+ in data center capacity. Logistics — largest private warehouse owner globally, ~1 billion sq ft. Real Estate — BREIT ($60B+ gross assets), diverse portfolio of rental housing, logistics, data centers. Private Equity — current portfolio includes Copeland, Bumble, Ancestry, Adevinta. Credit — Blackstone Mortgage Trust (BXMT, NYSE), ~$22B in assets. Previously: Hilton Hotels ($26B buyout, most profitable PE deal ever), Equity Office Properties ($39B buyout from Zell, disastrous timing), Vivint Smart Home, Refinitiv (sold to LSEG for $27B). Key public vehicle: BX stock (NYSE, market cap ~$170B).
Moderate relevance, primarily thematic. Schwarzman's 'don't lose money' principle aligns with our floor price philosophy. His thematic conviction on AI/data centers is directly relevant to our AGI thesis — Blackstone is betting tens of billions that AI infrastructure demand will be massive, which is a powerful signal from the world's most sophisticated real asset investor. BX stock itself is an interesting vehicle (a bet on alternative asset management growth + AI infrastructure). However, fundamental differences limit direct applicability: (1) Blackstone is a fee-extracting asset manager, not a principal investor aligned with our interests. (2) Leverage is core to their model. (3) We cannot access their deal flow or fund returns. (4) The institutional PE/real estate world operates on diff...
Portfolio manager of the Fidelity Contrafund since September 1990 — one of the longest tenures of any active mutual fund manager. Contrafund is one of the largest actively managed mutual funds in the world with approximately $130-150B in AUM. Danoff graduated from Harvard College and Wharton School of Business. Joined Fidelity in 1986. The fund was originally named 'Contrafund' for its contrarian approach, though Danoff has evolved the strategy toward growth-at-a-reasonable-price. Has been one of the most successful large-fund managers in history, delivering strong returns across multiple market cycles over 35+ years.
Growth-at-a-reasonable-price (GARP) with contrarian roots. Seeks companies with above-average earnings growth, strong management teams, and reasonable valuations relative to growth prospects. Famous for intensive management meetings — reportedly meets with over 1,000 management teams per year. Believes in understanding the people running companies as a key edge. Originally contrarian (buying out-of-favor names) but evolved to blend contrarian and growth approaches. Prefers companies that are gaining market share, have strong competitive positions, and demonstrate pricing power. Willing to own mega-cap names that dominate their industries.
Broadly diversified with large position count (300-500+ holdings) but with meaningful concentration at the top. Top 10 holdings typically represent 30-40% of fund assets. Given the massive AUM ($130-150B), the fund essentially resembles an enhanced index with significant active tilts. Must invest primarily in US equities. Growth-biased but not pure growth — holds value names when conviction warrants. Very low turnover by growth fund standards. Holds many positions for years. The sheer size constrains the opportunity set to large and mega-cap stocks.
Very strong over the long term. Since taking over in 1990, Danoff has delivered approximately 13-14% annualized returns, significantly outperforming the S&P 500 (approximately 10-11% annualized over the same period). This is remarkable given the fund's massive size, which typically creates a drag on performance. Has outperformed in most rolling 10-year periods. The fund has navigated the dot-com bust, 2008 financial crisis, and 2022 bear market without catastrophic drawdowns. Consistency across 35+ years and multiple market regimes is among the best in the mutual fund industry.
High. As a registered mutual fund, provides full portfolio disclosure, semi-annual shareholder reports, and regular commentary. Danoff occasionally gives interviews and speaks at conferences. Fidelity provides extensive data on the fund's performance, holdings, and sector allocation. However, Danoff is not known for the kind of intellectually rich shareholder letters that Buffett or Sequoia Fund provides — communications are more standard institutional fare.
High. No known controversies, regulatory issues, or ethical concerns in 35+ years of managing Contrafund. Has maintained consistent investment approach without style drift or gimmicks. Has not chased asset growth at the expense of performance — the fund's returns remain competitive despite enormous size. Fidelity as an institution has a strong compliance culture. Danoff's longevity and consistent approach speak to personal integrity and institutional trust.
Current top holdings typically include Meta Platforms, NVIDIA, Amazon, Microsoft, Alphabet, Apple, Berkshire Hathaway, Eli Lilly, UnitedHealth Group. Historically, Danoff has been early and right on many mega-cap winners including Amazon, Facebook/Meta (bought early and held), and NVIDIA. The portfolio reflects a who's-who of dominant American businesses.
Moderate. Danoff's long-term holding periods, focus on management quality, and willingness to own dominant businesses align with aspects of our philosophy. His contrarian roots resonate with our value orientation. However, his fund is far too diversified (300-500 holdings) to be considered concentrated. The GARP approach is different from our floor-price/downside-first methodology. The massive AUM means he cannot invest in the same opportunity set we target. Useful as a signal for which mega-cap names have long-term institutional conviction, but not a close philosophical match for following individual positions.
Cheah Cheng Hye (born 1954 in Penang, Malaysia) is one of Asia's most prominent value investors, sometimes called the 'Warren Buffett of Asia.' His story is one of the great rags-to-riches tales in Asian finance. He grew up in modest circumstances, never attended university, and started his career as a journalist at the Asian Wall Street Journal and Far Eastern Economic Review in the 1970s-80s. His journalism gave him deep exposure to Asian business and finance. He transitioned into fund management, working at Morgan Grenfell (later Deutsche Asset Management) in Hong Kong, where he managed Asian equity funds. In 1993, he co-founded Value Partners with V-Nee Yeh, starting with roughly US$5.5 million in assets. He built it into one of Asia's largest independent asset management firms, now ma...
Cheah is a classic bottom-up value investor with deep roots in Benjamin Graham and Warren Buffett's teachings, adapted for Asian markets. His core tenets: (1) Bottom-up fundamental research — Value Partners has over 40 investment professionals focused on Greater China and Asia, doing on-the-ground company visits and proprietary research; (2) Buy undervalued companies trading below intrinsic value with catalysts for value realization; (3) Long-term orientation — he aims to hold good companies through cycles rather than trade around them; (4) Margin of safety — seeks significant discounts to estimated intrinsic value; (5) Quality matters — increasingly shifted toward higher quality companies over the decades rather than pure deep value; (6) Focus on Greater China and Asia where informational...
Value Partners runs multiple strategies but the flagship is the Value Partners Classic Fund, launched in 1993. Portfolio characteristics: typically holds 40-80 positions with meaningful concentration in top holdings; predominantly Greater China equities (Hong Kong, mainland China H-shares and A-shares) with selective exposure across Asia Pacific; mix of large-cap and mid-cap names; sector focus has historically included financials, consumer, industrials, and technology; turnover is moderate — core positions are held for years but the portfolio is actively managed around valuations. The firm has expanded into fixed income, multi-asset, quantitative, and alternatives over the years, but equities remain the core. Cheah invests a significant portion of his personal wealth alongside clients. Th...
The Value Partners Classic Fund has one of the longest track records among Asian-focused funds, with over 30 years of performance history since 1993. Early performance was exceptional — the fund reportedly compounded at approximately 22% annualized in its first decade, massively outperforming the Hang Seng Index. However, the more recent record (2010s-2020s) has been much weaker. China and Hong Kong markets have significantly underperformed global markets, particularly US equities, during this period. The fund suffered during the 2015 China crash, the 2018 trade war, the COVID period, and especially the 2021-2023 China tech/property regulatory crackdown. Value Partners Group's AUM declined from a peak of roughly US$17 billion (around 2015) to US$6.2 billion by end of 2025 — a significant d...
Good transparency by Asian fund management standards. Value Partners is a publicly listed company on the Hong Kong Stock Exchange, so its financial results, AUM, and corporate governance are subject to regulatory scrutiny and public disclosure. The firm publishes regular market commentaries, investment letters, and fund factsheets. Cheah has given numerous interviews and speeches articulating his investment philosophy. However, position-level disclosure is less granular than US 13F requirements — specific holdings are reported periodically but not with the same frequency or detail as US-based managers. The firm's annual reports provide meaningful insight into strategy and performance. Cheah has been relatively candid about the challenges of investing in China during the recent difficult pe...
High integrity. Cheah's personal story — from a poor Malaysian Chinese family with no university education to building a multi-billion dollar asset management firm — speaks to genuine talent and hard work rather than connections or privilege. He invests alongside clients with substantial personal capital in Value Partners funds. No major scandals or ethical controversies have been associated with him or the firm. He has been consistent in his investment approach over three decades rather than chasing trends. Value Partners' fee structure is standard institutional (management fee plus performance fee on some products). His continued commitment to China/Asia investing through a very difficult period, rather than pivoting to where performance was easier, suggests conviction over opportunism. ...
Value Partners' holdings have historically focused on Greater China. The Classic Fund has held significant positions in major Chinese/HK companies including: China Mobile, Tencent, AIA Group, China Construction Bank, Ping An Insurance, CNOOC, various Hong Kong property developers and conglomerates. More recently, the firm has been positioned in areas they see as undervalued within China: state-owned enterprise reform beneficiaries, Chinese consumer companies, select technology names that survived the regulatory crackdown, and dividend-yielding Chinese financials. The firm has also selectively invested in other Asian markets (Japan, India, Southeast Asia) though China/HK remains the core. Specific current holdings are harder to track than US-based managers due to different disclosure regime...
Moderate relevance. Cheah's core philosophy — bottom-up value investing, margin of safety, long-term orientation, concentration — has meaningful overlap with our approach. His emphasis on downside protection and intrinsic value aligns with our floor price methodology. His willingness to invest when sentiment is worst is a quality we admire. However, several factors limit relevance: (1) His portfolio is China/Asia focused, which is a different universe from our current focus; (2) The recent weak performance (2015-2025) raises questions about whether deep value in China can generate returns in a market with structural governance and political risks; (3) Value Partners has grown into a large institutional firm ($6.2B AUM) with diversified products — less of a concentrated conviction investor ...
Shuhei Abe is the founder, president, and group CEO of Sparx Group (8739.T), one of Japan's leading independent asset management companies. He founded Sparx in 1989, making it one of Japan's earliest independent asset managers at a time when the industry was dominated by securities firm subsidiaries. Abe graduated from Babson College in the United States with an MBA. He began his career at Nomura Securities, where he worked in equity research and investment management. He reportedly was influenced early in his career by encounters with George Soros and his investment approach. Abe has been a pioneer in bringing Western-style fundamental investing to Japan, blending it with deep knowledge of Japanese corporate culture and governance. Sparx Group is publicly listed on the Tokyo Stock Exchang...
Abe's investment philosophy blends bottom-up fundamental analysis with a distinctive 'macro + bottom-up' approach. Key elements: (1) Deep fundamental research on individual companies — Sparx invests heavily in on-the-ground research, company visits, and understanding business models; (2) 'Invest in change' — Abe focuses on companies undergoing positive transformation, whether through management reform, governance improvements, or business restructuring; (3) Long-term orientation — Sparx aims to hold positions through business cycles; (4) Engagement and activism — rather than passive value investing, Abe believes in engaging with management to unlock value, making him an early proponent of what is now called 'constructive activism' or 'stewardship' in Japan; (5) Warren Buffett influence — A...
Sparx manages multiple strategies but the core Japanese equity funds typically hold 30-60 positions, representing meaningful but not extreme concentration. The focus is primarily on Japanese equities across market capitalizations, with particular strength in mid-cap and small-cap companies where informational advantages are greatest. Sparx also runs pan-Asian (One Asia), Korean, and other regional strategies. The firm has expanded into real assets (renewable energy, infrastructure) and private equity. The Japanese equity funds are long-only with no leverage. Turnover is moderate — positions are held for multi-year periods but the portfolio is actively managed. Sparx's approach to Japanese equities combines a value discipline with growth awareness — they are not pure deep value investors bu...
Sparx Group has a 35+ year track record in Japanese equities since 1989. The early track record was strong, particularly through the 1990s when Sparx identified value in a Japanese market that was broadly declining from bubble highs. Abe built one of Japan's most successful independent asset managers during a period when independent firms were rare in Japan. However, the overall Japanese equity market was in a secular decline/stagnation from 1989 to roughly 2012, which created a challenging environment. Sparx experienced significant AUM declines during the 2008 global financial crisis and struggled during the lost decades. More recently (2013-present), the Japan market has recovered strongly — particularly the governance reform narrative (Tokyo Stock Exchange reforms, Abenomics, Japan valu...
Moderate to good transparency. Sparx Group is publicly listed on the Tokyo Stock Exchange (8739.T), providing regular financial disclosures, earnings reports, and AUM data. The firm publishes investment commentaries and market perspectives. Abe gives interviews and speaks at investment conferences about his approach and views on Japan. However, individual fund-level performance data and detailed position-level disclosure is less accessible than US-based managers (Japan has different regulatory disclosure requirements). The firm's quarterly earnings releases provide overall AUM and business performance data. ESG and sustainability reporting is comprehensive. Abe has been relatively forthcoming about Sparx's approach in media appearances and his public advocacy for Japanese corporate reform.
High integrity. Abe's 35+ year commitment to building an independent asset management firm in Japan — a market that has been deeply unfashionable for most of that period — demonstrates genuine conviction and persistence. He stayed focused on Japan when most global investors had abandoned it. His advocacy for corporate governance reform in Japan was ahead of its time and aligned with shareholder interests, not just self-promotion. Sparx is a regulated, publicly listed company subject to oversight. No major scandals or ethical controversies are associated with Abe or Sparx. His personal investment of time and capital in Japan's market reform agenda suggests genuine commitment beyond fee generation. The firm's expansion into renewable energy and social impact investing is consistent with the ...
Sparx's specific fund holdings are not as widely disclosed as US managers' 13F filings. However, the firm has historically invested in well-known Japanese companies across sectors, particularly those benefiting from governance improvements: Toyota, Sony, Keyence, and other Japanese blue-chips and mid-caps that have been improving capital efficiency. Sparx has been a notable investor in Japanese companies that have increased dividends, initiated share buybacks, or improved return on equity in response to governance pressure. The Real Assets division has significant investments in Japanese renewable energy projects (solar, wind). The One Asia strategy extends into Korea, China, and other Asian markets. Abe personally holds a significant stake in Sparx Group itself.
Moderate relevance with some interesting elements. Positives: (1) Abe's emphasis on understanding businesses deeply and investing long-term aligns with our approach; (2) His 'invest in change' philosophy has been vindicated by Japan's recent governance revolution; (3) His Buffett-influenced value orientation resonates; (4) His engagement approach shows how active ownership can unlock value; (5) Japan is currently experiencing a structural re-rating that could continue for years. Limitations: (1) His portfolio is primarily Japan-focused, which is a specific geographic bet; (2) Sparx has diversified into multiple asset classes (real assets, PE) beyond pure equity investing; (3) Portfolio is more diversified (30-60 positions) than our concentrated approach; (4) No evidence of AGI awareness or...
Teng Ngiek Lian is the founder and chief investment officer of Target Asset Management, a Singapore-based value investing boutique. Target Asset Management is a small, private asset management firm that has operated with a very low profile for decades. Teng is one of Singapore's most respected but least well-known value investors. He manages a concentrated, long-only equity fund focused on Asian equities with a deep value orientation. Teng is known in value investing circles for his extremely concentrated portfolio (typically 10-20 positions), very long holding periods, and patient approach to capital allocation. He reportedly studied at the University of Singapore and developed his value investing philosophy independently, influenced by Benjamin Graham, Warren Buffett, and Philip Fisher. ...
Teng's philosophy is classic concentrated value investing with strong Buffett/Munger influences. Key elements based on what is known: (1) Extreme concentration — typically holds only 10-20 positions, with top holdings representing very significant portfolio weights; (2) Very long holding periods — years to decades, not months; (3) Deep fundamental research — Teng conducts thorough analysis of businesses, industries, and competitive dynamics before investing; (4) Quality over cheapness — like Buffett's evolution from Graham-style deep value to Munger-influenced quality investing, Teng appears to focus on good businesses at reasonable prices rather than mediocre businesses at cheap prices; (5) Margin of safety — buys at meaningful discounts to intrinsic value; (6) Circle of competence — stay...
Extremely concentrated and long-term. Target Asset Management typically holds 10-20 positions, making it one of the most concentrated professional portfolios in Asia. The portfolio is focused on Asian equities, with investments across Singapore, Hong Kong, Malaysia, and potentially other Asian markets. Holdings tend to be smaller and mid-cap companies where Teng believes he has informational or analytical advantages. The fund is long-only with no leverage or shorting. Turnover is very low — positions are held for years. Cash positions can be significant when Teng does not find compelling opportunities, reflecting his discipline in not deploying capital just for the sake of being fully invested. This portfolio style is the closest match to our own approach among the five investors in this g...
Detailed performance data for Target Asset Management is not publicly available due to the firm's private status and low profile. However, Teng's reputation in Singaporean and Asian value investing circles is strong — he is known as a consistent performer over multiple decades. The concentrated portfolio and long-term approach would have produced volatile returns in any given year but presumably strong compounding over longer periods (this is characteristic of concentrated value investors). The very fact that Target Asset Management has survived and maintained its approach for decades, despite the challenging environment for Asian value investing, suggests at least adequate risk management and returns. However, the lack of independently verifiable performance data is a significant limitati...
Very low transparency. Teng is one of the most private investors in this group. Target Asset Management does not have a significant public presence — no prominent website, no regular publications, no media interviews. Position-level disclosure is minimal. Performance data is not publicly available. Teng does not publish investment letters or give public talks about his approach. This extreme privacy is consistent with his investment style (concentrated, long-term, seeking informational advantages in under-followed stocks) but makes it very difficult for outside observers to learn from or verify his approach. While privacy itself is not a negative — many great investors are private — it limits the practical value of following Teng for our purposes.
Likely high integrity based on circumstantial evidence, but hard to verify due to low transparency. Positive indicators: (1) Deliberately keeping AUM small rather than scaling up to maximize fees — this suggests prioritizing returns over revenue; (2) Investing his own capital alongside clients; (3) Multi-decade track record with a consistent approach — no style drift; (4) Low profile and lack of self-promotion — Teng does not appear to be marketing himself or extracting rents; (5) No scandals or ethical controversies. Concerns: (1) With such limited public information, integrity is hard to assess with confidence; (2) Very small, private firms have less external oversight than larger, regulated, or publicly listed firms. On balance, the available evidence suggests strong integrity, but the ...
Specific holdings are not publicly disclosed. Based on Teng's known focus on concentrated Asian value investing, holdings would likely include a mix of smaller Singapore-listed companies, Hong Kong-listed companies, and potentially Malaysian or other Southeast Asian equities. His preference for concentrated positions in undervalued, under-followed companies means his holdings are likely not the large-cap names that dominate Asian indices. The lack of public disclosure makes it impossible to identify specific positions or use his holdings as a source of investment ideas.
High philosophical relevance but limited practical relevance. Positives: (1) Teng's approach is the closest to our philosophy among this group — concentrated, long-only, long-term, quality-focused, patient; (2) His deliberate choice to keep AUM small for flexibility mirrors our thinking; (3) His willingness to hold cash when opportunities are scarce is exactly the discipline we aspire to; (4) His buy-and-hold orientation and focus on quality businesses aligns perfectly. Limitations: (1) Extremely low transparency means we cannot actually follow his ideas, learn from his analysis, or validate his track record; (2) His focus is on smaller Asian equities, a different universe from our current focus; (3) No evidence of AGI awareness or technology disruption analysis; (4) The practical informat...
Orlando Bravo (b. 1970 in Puerto Rico) is the managing partner of Thoma Bravo, one of the largest and most successful software-focused private equity firms in the world. After graduating from Brown University and Stanford Business School, Bravo joined Thoma Cressey (as it was then known) in 2003, transforming it from a middle-market generalist PE firm into the dominant acquirer of enterprise software companies. Under his leadership, Thoma Bravo has grown from managing ~$1 billion to over $160 billion in AUM by 2025, making it one of the top 10 PE firms globally. Bravo has personally led or overseen more than 400+ software and technology transactions. His net worth is estimated at $8+ billion, making him one of the wealthiest people in PE. Thoma Bravo's strategy is uniquely focused: they al...
Bravo's philosophy is highly disciplined and sector-specific: (1) Software-only focus — Thoma Bravo invests almost exclusively in enterprise software, SaaS, cybersecurity, and related technology companies. This deep sector expertise creates significant information advantages. (2) Operational improvement — the firm has a proven playbook for increasing software company margins by 1,000-2,000+ basis points through pricing optimization, go-to-market efficiency, R&D prioritization, and cost rationalization. (3) Buy-and-build consolidation — acquiring a platform company and bolting on smaller acquisitions to build scale. (4) Recurring revenue emphasis — strong preference for SaaS/subscription models with high retention rates, which provide predictable cash flows that support leverage. (5) Margin...
Concentrated within software but diversified across 50-80+ portfolio companies at any time. Key sub-sectors: cybersecurity (Sophos, SailPoint, Proofpoint, Barracuda, McAfee Enterprise, ForgeRock, Ping Identity), ERP/financial software (Epicor, Sage, Apttus), healthcare IT (ConnectWise, Imprivata, MeridianLink), HR/payroll (Cornerstone OnDemand, Planview), data/analytics (Qlik, Dynatrace, Informatica). The portfolio is sector-concentrated (a positive signal) but company-diversified (many positions). Thoma Bravo also operates through multiple fund sizes: flagship large-cap, mid-cap Discover Fund, and small-cap Explore Fund. Most investments are take-private or buy-and-build, meaning they show up in public markets primarily at entry (take-private) and exit (IPO/sale).
Exceptional within PE. Thoma Bravo's flagship funds have consistently delivered top-decile returns, with reported net IRRs typically in the 25-30%+ range across vintage years. Notable successes include: SailPoint (acquired, improved, took public, then re-acquired — generating returns at each stage), Sophos (cybersecurity, strong returns), ConnectWise (IT management, significant value creation), Dynatrace (acquired as part of Compuware, spun out, IPO'd — massive value creation), Digital Insight/NCR (strong returns), Barracuda Networks (multiple transactions), Proofpoint (acquired for $12.3B in 2021, one of the largest cybersecurity PE deals), Qlik (analytics platform), and Epicor (industrial ERP). The consistency is remarkable — the firm has a repeatable playbook that works across different...
Low-to-moderate. Thoma Bravo is a private firm (not publicly listed), so there are no SEC filings, quarterly reports, or public fund performance disclosures. Information comes primarily from: (1) Bravo's interviews, conference appearances, and media profiles, (2) Preqin/PitchBook fund performance data available to institutional investors, (3) public filings when portfolio companies are taken private or public (merger proxies, IPO filings), (4) occasional case studies in business school curricula. Bravo is relatively media-friendly and gives thoughtful interviews about software investing, but the firm itself provides minimal public disclosure. This is standard for private PE but a weakness from a transparency perspective compared to public equity managers. Individual deal returns, fund leve...
Complicated. On the positive side, Bravo is widely respected for his deep software expertise, disciplined investment approach, and value creation track record. He has been a significant philanthropist, particularly in Puerto Rico (donating $100M+ after Hurricane Maria and to education). However, there is a serious negative: in 2023, Bravo was accused of sexual assault in a lawsuit filed in Florida. He denied the allegations. The case was settled confidentially. This creates meaningful uncertainty about personal integrity. Separately, the Thoma Bravo operational playbook — while effective financially — has been criticized for aggressive cost-cutting that can harm product quality, employee morale, and customer service at portfolio companies. Some cybersecurity professionals have noted that p...
Current and recent portfolio companies include: SailPoint (identity security — re-acquired 2022 for $6.9B), Proofpoint (email security — acquired 2021 for $12.3B), Sophos (cybersecurity), ConnectWise (IT management), Epicor (industrial ERP), Qlik (analytics), Planview (portfolio management), Apttus/Conga (revenue management), Imprivata (healthcare IT), ForgeRock (identity), Ping Identity (identity — acquired 2022 for $2.8B), Barracuda Networks (security), LogRhythm/Exabeam (SIEM — merged 2024), MeridianLink (financial software), Calypso (capital markets software), Hyland (content services), and 50+ others. Recent notable deal: acquisition of Darktrace (AI cybersecurity, ~$5.3B, 2024).
Moderate relevance — higher than typical PE firms. Bravo's sector concentration in software is philosophically aligned with our focus on understanding businesses deeply. His emphasis on recurring revenue and margin improvement creates genuine downside protection, which resonates with our floor-price philosophy. The software sector he dominates is directly relevant to our AGI thesis. However, several factors limit applicability: (1) most Thoma Bravo investments are private, so we cannot follow into them as public equity investors, (2) the leverage, fees, and finite holding periods are structurally different, (3) the cost-cutting playbook may not work as well in an AI era where R&D investment is critical. The most useful signal from Thoma Bravo is identifying which software sub-sectors (cybe...
Cliff Asness (born 1966) is a co-founder and managing principal of AQR Capital Management, one of the world's largest quantitative investment firms with approximately $100+ billion in AUM. He earned his PhD in finance from the University of Chicago under Eugene Fama (the father of the efficient market hypothesis and factor investing). Before founding AQR in 1998, he worked at Goldman Sachs where he ran the quantitative research group. Asness is one of the most intellectually prominent figures in modern finance — he has published extensively in academic journals and is known for his sharp, often humorous public writings on Twitter/X and in AQR's research papers. He is a passionate advocate for factor investing (value, momentum, quality, low volatility) and has been one of the most vocal def...
Asness is the foremost practitioner of systematic factor investing. His core belief is that certain factors — value (buying cheap, selling expensive), momentum (following recent trends), quality (owning profitable, stable companies), and defensive/low-volatility — have persistent risk premia that can be harvested systematically across asset classes and geographies. Unlike Renaissance, AQR's factors are well-known and academically documented; the edge comes from disciplined, diversified implementation at scale rather than from secret signals. Asness is deeply influenced by Fama-French research and believes markets are mostly efficient but that behavioral biases create persistent factor premia. He is a strong advocate of diversification across factors, asset classes, and geographies. He is i...
AQR's portfolios are highly diversified, systematic, and factor-driven. They hold hundreds to thousands of positions across global equities, bonds, currencies, and commodities. Portfolios are constructed to maximize exposure to target factors while minimizing unintended bets. AQR uses moderate leverage in some strategies. Turnover is moderate — lower than Renaissance but much higher than a concentrated fundamental investor. The firm offers a wide range of strategies from long-only factor tilts to market-neutral hedge funds to alternative risk premia. The 13F shows broad, diversified equity holdings with no single large concentrated bet. This is the antithesis of concentrated, conviction-driven investing.
AQR's track record is mixed and strategy-dependent. The firm's early years (1998-2008) were strong, but the 2018-2020 period was devastating — value factors suffered historic underperformance, and AQR's flagship Absolute Return Fund lost significant money. AUM dropped from a peak of ~$226 billion (2018) to ~$100 billion (2020). However, since 2021, value has recovered strongly, and AQR has had an excellent run — 2022-2024 were very strong years as value, momentum, and trend-following strategies all performed well. The firm's long-only factor strategies have generally matched or slightly outperformed benchmarks over full cycles but with significant tracking error and painful drawdown periods. AQR's hedge fund strategies have generated mid-to-high single-digit returns with low market correla...
Asness and AQR are exceptionally transparent for a quantitative firm. AQR publishes extensive research papers, white papers, and blog posts explaining their investment philosophy, factor definitions, and methodology. Asness himself is prolific on Twitter/X, engaging in detailed public debates about value investing, factor premia, and market dynamics. AQR's research library is one of the best in the industry and freely available. The firm's strategies are based on well-documented academic factors rather than proprietary black-box signals. While specific portfolio positions and implementation details are not disclosed, the intellectual framework is fully transparent. This is a stark contrast to Renaissance's total opacity. Among quant firms, AQR is by far the most transparent.
Asness scores highly on integrity. He is intellectually honest — he publicly acknowledged when his strategies were underperforming and wrote candidly about whether value was 'dead.' He did not blame external factors or make excuses; he engaged with the criticism head-on. He has been consistent in his philosophy even during painful periods, which demonstrates conviction rather than style-drift. He donates significantly to education and civic causes. He has been open about his mistakes and limitations. The main criticism is that AQR charges significant fees for strategies based on well-known, publicly documented factors — some argue you can implement value/momentum tilts yourself at much lower cost. But Asness would counter that disciplined implementation at scale is harder than it looks. No...
AQR's 13F shows extremely diversified holdings across hundreds of stocks. Recent top positions have included large positions in broad market names like Apple, Microsoft, Nvidia, Amazon, and other mega-caps, but also significant positions in international equities and value names. The portfolio is constructed systematically to capture factor exposures, so individual positions are not meaningful to follow — they reflect factor scores rather than fundamental conviction. Following AQR's 13F would be essentially useless for a concentrated fundamental investor.
Cliff Asness and AQR have moderate intellectual relevance despite low practical relevance. We cannot and should not try to implement systematic factor strategies. However, Asness' intellectual contributions are valuable: (1) His research on value investing validates our value-oriented approach with rigorous data, (2) His writings on behavioral biases and patience during drawdowns are psychologically useful, (3) His framework for thinking about 'what is cheap' across multiple dimensions can inform our fundamental analysis, (4) His intellectual honesty about when his strategies fail is a model for how we should think about our own mistakes. AQR's research papers on topics like 'value is not dead' and 'the interaction of value and momentum' are worth reading. But as a source of specific inves...
Born circa 1970. MBA from Columbia Business School. Started his career at investment banks before joining Ramius Capital (later Cowen) where he ran the activist fund. Founded Starboard Value LP in 2011 as a spin-out from Ramius Capital. Net worth estimated at $1-2 billion. Starboard manages approximately $6-8 billion in AUM. Has become one of the most active and successful activist investors of the past decade. The firm has been involved in over 100 activist campaigns since the principals began managing money in this style in 2002. Known for very detailed, research-driven activism with a focus on operational improvements and corporate governance. Notable for replacing the entire board of Darden Restaurants (Olive Garden parent) in 2014 — one of the most dramatic activist victories in histo...
Starboard practices 'deep value activism' — identifying publicly traded companies that are significantly undervalued due to operational inefficiency, poor capital allocation, or governance failures, then actively engaging to unlock value. The approach is highly research-intensive, with detailed analysis of operational benchmarks, margin comparisons to peers, strategic alternatives, and governance best practices. Starboard typically targets mid-cap companies ($2B-$30B) that are underperforming peers on margins, returns on capital, or growth. They seek board representation to implement changes. The focus is on operational improvement rather than financial engineering — Starboard wants to make companies better operators, not just lever them up or force asset sales. They combine quantitative a...
Moderately concentrated, mid-cap focused. Starboard typically holds 15-25 positions with meaningful concentration in top 5-10 names. Targets tend to be mid-cap companies in technology, industrials, consumer, and healthcare. Position sizes in target companies are typically 1-5% ownership stakes. The portfolio has a higher-quality bias than some activists — Starboard often targets companies that have good underlying businesses but poor execution. Uses primarily long equity positions; limited use of leverage or shorts. Recent campaigns have included some larger-cap targets. Portfolio turnover is moderate — not as quick as a trader, but not a long-term holder either.
Strong, particularly in the 2011-2020 period. The Darden Restaurants campaign (2014) is the signature achievement — Starboard replaced the entire board, brought in new management, and oversaw a dramatic operational turnaround that created billions in shareholder value. Other notable wins: AOL (activism, eventually sold to Verizon), Marvell Technology (board changes, turnaround), Yahoo (board seats), Office Depot/Staples (merger advocacy), Cimpress (Vistaprint parent, operational improvements). More recent campaigns have included Pfizer (2024, pushed for operational improvements and cost cuts), Algonquin Power, AECOM, and various tech companies. Results have been more mixed in recent years as the easy activism targets have been picked over. By activist fund standards, Starboard has generate...
Moderate-to-high for an activist fund. Starboard publishes detailed presentations for its activism campaigns, often 50-100+ pages with granular operational analysis. These presentations are often publicly available and provide exceptional analytical depth. 13F filings give visibility into long positions. Jeff Smith has been willing to speak publicly about investment theses, though less media-savvy than Icahn or Loeb. The firm's research quality is widely respected, even by target company management teams. However, as a private fund, detailed performance data, position sizing, and non-equity investments are not publicly disclosed.
Good. Jeff Smith has built a reputation as a serious, research-driven investor who wins campaigns based on the quality of his analysis rather than bluster or intimidation. The Darden campaign demonstrated intellectual honesty — the detailed analysis of Olive Garden's operations (including the famous 'stop salting the pasta water' anecdote) was so thorough that shareholders overwhelmingly supported replacing the entire board. Smith doesn't engage in personal attacks on management (unlike early Loeb or Icahn) and generally maintains professional relationships even with targets. No significant legal issues, SEC enforcement actions, or ethical controversies. The firm's alumni have gone on to successful investment careers, suggesting a healthy organizational culture. However, like all activists...
Current/recent major positions: Pfizer (major 2024 campaign), Algonquin Power, various mid-cap tech and industrial companies. Historical notable plays: Darden Restaurants (Olive Garden — complete board replacement), AOL, Marvell Technology, Yahoo, Office Depot/Staples, Cimpress (Vistaprint), Advance Auto Parts, Perrigo, AECOM, Commvault, Brink's. Increasingly targeting larger companies (Pfizer represents a shift toward mega-cap activism).
Low-moderate relevance. Starboard's research quality is excellent and their operational analysis can be educational, particularly the detailed margin benchmarking and strategic analysis in their public presentations. However, their activism approach (1-3 year timeline, mid-cap targets, operational fix-it situations) is different from our long-term quality compounding philosophy. The portfolio has limited overlap with our focus areas — Starboard targets underperformers for operational improvement, while we seek fundamentally great companies. Their Pfizer campaign is interesting but represents a different type of investment thesis than what we pursue. Their presentations are worth reading for analytical technique, but their stock picks are unlikely to be actionable for our strategy. No meani...
Chase Coleman III (born 1975) founded Tiger Global Management in 2001 at age 25 with seed capital from Julian Robertson of Tiger Management. He graduated from Williams College where he was a lacrosse player. Coleman was one of Robertson's youngest proteges and was given capital to start his own fund after working at Tiger Management. He quickly distinguished himself through early, aggressive bets on technology companies, most notably being an early investor in Facebook (pre-IPO), LinkedIn, Spotify, JD.com, and numerous other tech companies in both public and private markets. Tiger Global expanded massively into venture capital during 2020-2021, becoming one of the most prolific late-stage venture investors globally, deploying billions at rapid pace. Net worth estimated at $8-10 billion. Th...
Growth-oriented technology investor with a global focus. Coleman's approach combines top-down thematic investing (identifying secular technology trends) with bottom-up fundamental analysis. Tiger Global is known for: (1) Aggressive growth investing -- willing to pay up for high-growth companies, (2) Global scope -- significant exposure to China/Asia tech (JD.com, Sea Limited, Coupang), (3) High conviction positions -- top 10 holdings represent 85.6% of portfolio, (4) Venture capital crossover -- massive private market investing alongside public equities, (5) Speed of deployment -- Tiger Global was known for making investment decisions in days rather than months during the 2020-2021 venture boom. Philosophy is fundamentally growth-at-a-reasonable-price but skews heavily toward momentum and ...
Highly concentrated growth/technology portfolio. 54 equity holdings with top 10 representing 85.6% of the portfolio. AUM approximately $29.7B (13F). Heavy technology and internet weighting. Significant China/Asia exposure through companies like Sea Limited, JD.com, and others. Both public equities and private venture investments (private book was historically larger than public). Portfolio turnover is moderate-to-high -- willing to trade around positions. Uses both long and short strategies.
One of the best long-term track records among hedge fund managers, though severely marred by 2022. From 2001-2020, Tiger Global's long fund delivered approximately 20%+ annualized returns, making Coleman one of the most successful investors of his generation. Key years: 2020 return of approximately +48%, 2021 was a banner year for both public and private books. However, 2022 was catastrophic: the long-only fund lost approximately 52%, one of the worst single-year losses for a major hedge fund, driven by extreme tech growth stock exposure as rates rose sharply. The private venture book also suffered massive markdowns. Recovery has been partial -- 2023 and 2024 saw positive returns but have not fully recouped 2022 losses. Q4 2025 showed a -2.49% loss. The 2022 blowup revealed that the strate...
Moderate transparency through 13F filings (quarterly, 45-day lag). Tiger Global is a private fund and does not publicly share detailed performance figures, strategy documents, or investor letters. The firm became more visible during 2020-2021 due to its enormous venture capital deployment, but this was not by choice -- the sheer volume of deals made secrecy impossible. The private venture portfolio is not disclosed via 13F, making the full picture harder to assess. Overall, standard hedge fund transparency -- compliant but not proactively open.
No major fraud or ethical scandals. However, significant concerns: (1) The 2020-2021 venture boom saw Tiger Global accused of inflating valuations by moving too fast and paying too much, which may have contributed to the broader tech bubble, (2) The speed of deal-making during the boom (sometimes making $100M+ investments after a single Zoom call) raised questions about fiduciary rigor, (3) The 52% loss in 2022 raised legitimate questions about risk management and whether the fund was over-concentrated and effectively leveraged to a single factor (growth). No insider trading issues or regulatory actions. Coleman is relatively low-profile and avoids media. Personal integrity appears solid, but the fund's risk management during 2020-2022 is a legitimate concern.
As of Q4 2025 (13F), top holdings heavily concentrated in technology: Microsoft (MSFT), Meta Platforms (META), Sea Limited (SE), Apollo Global Management (APO), JD.com (JD), Coupang (CPNG), ServiceNow (NOW), and various other tech/internet names. Historical notable investments include early positions in Facebook (pre-IPO), LinkedIn, Spotify, and Flipkart. The portfolio maintains significant China/Asia internet exposure alongside US mega-cap tech.
Mixed relevance. Positives: Coleman's concentration level (85.6% in top 10) aligns with our preference for high-conviction investing. His technology focus is relevant to our AGI thesis. His willingness to take large positions in companies he understands deeply is admirable. Negatives: Tiger Global's approach is fundamentally growth/momentum oriented, not value/downside-protection oriented. The 52% loss in 2022 demonstrates a lack of the downside protection we prioritize. The use of leverage and shorting diverges from our long-only, no-leverage approach. The venture capital activity introduces risks we don't want. His approach is 'pay up for growth' rather than 'little chance of losing money.' We can learn from his technology selection ability but should not follow his risk management appro...
Born 1961, grew up in Santa Monica, California. Graduated from Columbia University with a degree in economics in 1983. Started his career at Warburg Pincus, then worked at several other firms before founding Third Point LLC in 1995 with $3.3 million in capital. Net worth estimated at $3-4 billion. Third Point manages approximately $12-15 billion in AUM. Known for his sharp-tongued, aggressive activist letters to management (often colorfully critical), though he has mellowed somewhat in recent years. Also known for his philanthropic activities and art collecting. Third Point is a multi-strategy hedge fund that combines activist investing with event-driven, distressed debt, and long/short equity strategies.
Loeb is a multi-strategy investor who blends activism with event-driven and fundamental long/short investing. Unlike pure activists who focus solely on governance and operational changes, Loeb is first and foremost a stock picker who adds an activist overlay when he believes management is underperforming. His approach: (1) identify companies trading below intrinsic value due to operational inefficiency, strategic missteps, or market misunderstanding; (2) take a meaningful position; (3) if needed, push for changes through letters, board representation, or public campaigns. He targets a wide range of sectors including tech, media, consumer, industrials, and financial services. Loeb has increasingly moved toward tech and growth-oriented companies in recent years, including significant positio...
Moderately diversified for a hedge fund, with 30-50+ positions but meaningful concentration in top 5-10 holdings. Third Point's 13F typically shows a mix of large-cap tech (Alphabet, Amazon, Meta), consumer companies, industrials, and special situations. Position sizes in top holdings can be 5-10% of the portfolio. Loeb is an active trader — turnover is higher than a buy-and-hold investor, with typical holding periods of 6 months to 3 years. The portfolio has become increasingly tech-heavy in recent years, reflecting Loeb's recognition that technology companies offer the best risk-reward. Uses long/short strategies, credit, and derivatives. Not a concentrated, long-term compounder — more of a sophisticated hedge fund operator.
Strong overall. Third Point has generated estimated annualized returns of approximately 15-16% net of fees since inception in 1995, which is excellent for a hedge fund over nearly 30 years. Major wins: Yahoo (pushed for CEO change and Alibaba stake monetization), Sotheby's (activist campaign, company sold), Sony (pushed for entertainment spinoff, strong returns), Dow Chemical (pushed for separation, merged with DuPont), Baxter International, Star Gas Partners (famous scathing letter). More recent activity has included significant tech positions that have benefited from the AI boom. However, performance has been inconsistent year-to-year, with some down years and periods of underperformance. Third Point Investors (London-listed vehicle, TPOU) provides some public performance visibility. The...
Moderate. Third Point files 13F quarterly, giving visibility into long equity positions. Loeb's activist letters are publicly available and often highly analytical. Third Point Investors (TPOU), the London-listed closed-end fund, provides regular NAV updates and some performance disclosure. However, as a hedge fund, short positions, derivatives, credit positions, and private investments are not disclosed. Loeb has become less publicly vocal in recent years compared to his earlier career when he was known for his combative public letters. The multi-strategy nature of the fund means 13F filings only show a fraction of total activity.
Generally good, with some caveats. Loeb is respected as a sharp analyst and honest communicator, even if his early career letters were sometimes gratuitously personal and inflammatory. He has mellowed with age and success. No significant legal issues, SEC enforcement actions, or fraud allegations. He has been a significant philanthropist. Some critics note that his activism can be short-term oriented — pushing for quick fixes (buybacks, spinoffs, asset sales) that boost near-term stock price rather than long-term value creation. His personal wealth management (selling positions quickly after activist campaigns succeed) sometimes raises questions about alignment with long-term shareholders. But by hedge fund standards, his integrity is above average.
Recent/current major positions: Alphabet/Google, Amazon, Meta, PG&E, Danaher, various tech names. Historical notable plays: Yahoo (activism, Alibaba stake), Sony (entertainment spinoff push), Sotheby's (activism, company sold), Dow Chemical (merger with DuPont), Baxter International, Campbell Soup, Nestlé, Bath & Body Works, Prudential Financial. Third Point has increasingly skewed toward large-cap tech in recent years.
Moderate relevance. Loeb's increasing focus on tech companies and his recognition of AI/technology trends makes him more relevant than other activists in this group. His positions in Alphabet, Amazon, and Meta overlap with companies we'd analyze. His analytical letters provide useful perspectives on company strategy. However, his hedge fund style (high turnover, long/short, multi-strategy) is fundamentally different from our long-term, concentrated, long-only approach. His positions change frequently, so following his 13F for stock ideas requires understanding that he may be in and out quickly. His track record is strong but driven partly by trading and hedging skill rather than long-term compounding. More useful as an analytical resource than as a portfolio to follow.
Leigh Goehring and Adam Rozencwajg co-founded Goehring & Rozencwajg (G&R) in December 2015 as a fundamental research firm focused exclusively on contrarian natural resource investments. Leigh Goehring has been investing in natural resources since 1991, beginning at Prudential Jennison where he managed the Jennison Natural Resources Fund. He is considered one of the most experienced and respected natural resource investors globally, with over 30 years of dedicated sector experience. Adam Rozencwajg joined Chilton Investment Company in 2007, where he focused on natural resource and commodity investments. At G&R, they manage the Global Natural Resources Strategy, maintaining portfolios of 50-70 positions across energy, metals, mining, and agriculture. The firm publishes widely-read quarterly ...
G&R's philosophy is deeply contrarian and fundamentals-driven within the natural resource space. Core tenets: (1) Commodities move in long-duration supercycles driven by capital spending cycles - periods of underinvestment lead to supply shortfalls that drive multi-year price increases; (2) The current era represents severe underinvestment in oil, gas, uranium, copper, and other critical resources, setting up a structural supply deficit; (3) They invest when commodity prices are depressed and investor sentiment is discouraged, believing this is precisely when financial measurements are cheapest; (4) Deep bottom-up fundamental research at both the commodity level (supply/demand modeling) and the security level (individual company analysis); (5) Contrarian willingness to invest in deeply unf...
Diversified within natural resources but concentrated in a single sector. Portfolios contain 50-70 positions spanning oil and gas producers, uranium miners, copper miners, gold miners, agricultural companies, and other resource equities. Within natural resources, they seek a balance between their best ideas and reasonable diversification. Portfolio turnover is low at 20-25% annually, indicating a medium-to-long-term holding period. They invest globally, including in emerging market resource companies. The strategy is long-only and does not use commodity futures or derivatives. Assets under management are not publicly disclosed but appear to be in the low hundreds of millions based on available information.
G&R has had periods of strong performance, particularly during commodity bull markets. Their thesis on structural underinvestment in natural resources has been partially vindicated: oil prices rose significantly in 2021-2022, uranium prices tripled from 2021-2024 lows, and copper prices have strengthened on electrification demand. However, their persistently bullish commodity stance has also meant enduring extended periods of underperformance when commodity prices are weak or declining. They were early on uranium (which eventually worked) and consistently bullish on oil (which has been more mixed given shale supply response and energy transition dynamics). Their long-term performance likely tracks closely with commodity cycles: strong during 2020-2022 when resources rallied hard, weaker du...
Very high. G&R publishes detailed quarterly commentaries that are freely available on their website and widely distributed. These commentaries include deep fundamental analysis of commodity supply/demand dynamics, geological analysis, and specific company discussions. They also produce blog posts, podcast appearances, and media interviews. Their research is intellectual and substantive, not promotional. The quarterly commentaries have built a loyal following among commodity investors and are considered some of the best publicly available natural resource research. However, actual fund performance figures are not publicly disclosed.
High. Goehring and Rozencwajg maintain consistent intellectual standards in their research. They acknowledge complexity and uncertainty in commodity markets rather than making simplistic predictions. Their long track records (Goehring since 1991) demonstrate commitment to the natural resource space through multiple cycles, including painful bear markets. They do not appear to engage in asset-gathering behavior or marketing gimmicks. Their research is genuine and reflects deep domain expertise. No known regulatory issues or ethical controversies.
G&R does not publicly disclose specific portfolio holdings, but based on their published research and commentary, their major thematic exposures likely include: Oil and gas producers (onshore conventional and unconventional), uranium miners (they have been vocal bulls on uranium since $20-30/lb levels, including companies like Cameco, Kazatomprom, and junior developers), copper miners (thesis on electrification driving structural demand increase), gold miners (as monetary hedge), and agricultural companies. They have been particularly vocal about: (1) Oil supply deficits from OPEC underinvestment, (2) Uranium supply crunch from reactor restarts and new builds, (3) Copper shortage from EV/renewable buildout, (4) Natural gas as a transition fuel. Specific equity names are generally not discl...
Low-to-moderate relevance. G&R's deep contrarian approach and willingness to invest in deeply unfashionable areas resonates with our philosophy. Their emphasis on buying when assets are cheap and sentiment is negative aligns with our floor-price methodology. However, their exclusive focus on natural resources limits direct applicability - they cannot help us analyze technology, healthcare, or other sectors. Their commodity supercycle thesis may conflict with our AGI thesis, which could accelerate renewable energy adoption and reduce fossil fuel demand. Their 50-70 position portfolio is also more diversified than our preferred extreme concentration. The quarterly commentaries are worth reading for commodity market education, but the investment approach is sector-specific rather than broadly...
Born 1942, grew up in Brooklyn, New York. Dropped out of the Wharton School at University of Pennsylvania. Started in business with his family's frozen food distribution company, which he grew into a major food conglomerate. Co-founded Trian Fund Management in 2005 with Peter May and Ed Garden, after earlier ventures including Triangle Industries (which became one of the largest packaging companies in the US). Net worth estimated at $1.8-2 billion. Trian manages approximately $8-10 billion in AUM. Known for 'constructive activism' — working collaboratively with management and boards rather than launching hostile campaigns. Has served on the boards of numerous major corporations including Procter & Gamble, Sysco, Wendy's, Heinz, Mondelez, DuPont, GE, Janus Henderson, Unilever, and most rece...
Peltz practices what he calls 'constructive engagement' or 'operational activism.' Unlike hostile raiders, Trian typically acquires a meaningful stake (1-5%), publishes detailed white papers outlining operational improvements, and seeks board representation to implement changes from within. The focus is on large-cap, well-known companies that Trian believes are underperforming their potential due to poor cost management, strategic drift, or governance issues. Peltz looks for companies with strong brands and market positions that are 'bloated' and can be improved through better operational discipline, margin expansion, portfolio rationalization, and capital allocation. He often draws on his own operational experience in the food industry. Trian's approach is relatively long-term by activist...
Moderately concentrated, large-cap focused. Trian typically holds 8-15 positions, all in large, well-known companies. The portfolio is not as concentrated as a Buffett or Munger, but much more concentrated than a typical hedge fund. Holdings tend to be in consumer staples, industrials, and financial services — companies with recognizable brands and stable cash flows. Position sizes are typically $500M-$2B. Trian publishes detailed white papers for their activism campaigns, which are unusually transparent for the industry. They tend to hold positions for 3-5 years, which is longer than most activists but shorter than our ideal 5-10+ year horizon.
Mixed but generally positive over Trian's history. Major wins: Heinz (acquired by Berkshire/3G, huge return), Wendy's (operational turnaround, 3x+ return), Sysco (margin improvements), DuPont (board seats, eventual Dow merger). Notable mixed outcomes: Procter & Gamble (won proxy fight, but unclear value added), GE (joined board during troubled period, outcome debatable). Recent setbacks: Disney proxy fight in 2024 — Peltz ran an expensive campaign for board seats and lost, which was seen as a significant defeat. Unilever — pushed for changes, some implemented. Overall, Trian has generated estimated annualized returns in the mid-teens over its history, which is solid but not exceptional. The fund's performance has been inconsistent in recent years, and the Disney proxy loss was a notable re...
High for an activist fund. Trian is known for publishing detailed white papers (often 50-100+ pages) outlining their thesis for each target company, including specific operational improvements, margin targets, and strategic recommendations. These white papers are often publicly available. 13F filings provide visibility into holdings. Peltz is a frequent media presence and speaks openly about his positions. The firm's approach of 'constructive engagement' inherently requires a degree of transparency. However, as a private fund, detailed performance data and fund-level financials are not publicly disclosed.
Generally high. Peltz's 'constructive' approach distinguishes him from more aggressive activists. He has a reputation for being a straight-shooter who follows through on commitments. Former targets like P&G's CEO have publicly praised his board contributions. However, some critics argue that Trian's activism sometimes prioritizes short-term cost cutting (margin improvement) over long-term investment, which can hurt companies' competitive positions. The Disney proxy fight raised some questions — Peltz's campaign was seen by some as ego-driven rather than value-driven, and his loss suggested shareholders didn't buy his thesis. No significant legal issues, SEC violations, or ethical controversies in his career. His personal lifestyle (he's known for lavish spending and celebrity social circle...
Current/recent: Janus Henderson, Ferguson Enterprises, Unilever (exited 2024), Disney (proxy fight, no board seat). Historical: Heinz (sold to Berkshire/3G), Wendy's (multi-year engagement), Sysco, DuPont/Dow, Procter & Gamble, GE, Mondelez, PepsiCo, BNY Mellon, Legg Mason, Invesco.
Low-moderate relevance. Trian's operational activism approach and focus on large-cap underperformers is different from our quality-compounding philosophy. Peltz is looking for 'fix-it' situations, while we're looking for fundamentally great companies at safe prices. The constructive approach and longer holding periods (3-5 years) are somewhat aligned, and his white papers can be educational about operational analysis. However, the portfolio skews heavily toward consumer staples and industrials with little tech or AGI exposure. His track record is solid but not exceptional, and his recent Disney loss suggests declining influence. His age (82) raises the same succession questions as Icahn. Following Trian's white papers for analytical insight could be useful, but their investment picks are u...
Born 1939. Graduated from Brown University (1961) and Columbia Business School. Founded Quest Advisory Corporation in 1972, which became Royce & Associates. Took over management of the Pennsylvania Mutual Fund in 1972, transforming it into one of the first and most prominent small-cap value funds in the US. Often called the 'godfather of small-cap investing' — he was among the earliest institutional investors to focus systematically on micro-cap and small-cap stocks at a time when most professional investors ignored companies under $1B in market cap. Built Royce & Associates into a major small-cap specialist with $15-20B in AUM at peak. Sold the firm to Legg Mason in 2001 (later acquired by Franklin Templeton in 2020), but continued to manage money and serve as co-CIO. Now in his mid-80s, ...
Royce's approach centers on buying small-cap stocks at prices below his estimate of intrinsic value, with an emphasis on quality factors: strong balance sheets, high returns on invested capital, sustainable competitive advantages, and capable management. He coined the concept of 'absolute value' in small-cap investing — looking for companies trading at discounts to their private market value or asset value, regardless of relative valuation metrics. Key principles include: (1) Focus on downside protection before upside potential — he frequently quoted Buffett's 'don't lose money' rule. (2) Look for companies with little or no debt. (3) Favor companies generating free cash flow. (4) Be patient — small-cap value requires longer holding periods as catalysts can take years to materialize. (5) D...
Highly diversified within small-cap. Royce Funds typically held 200-400+ positions across their various funds. The flagship Pennsylvania Mutual Fund and Royce Total Return Fund each held 200+ names. This extreme diversification is partly structural — in micro-cap and small-cap, individual company risk is high (bankruptcy, fraud, cyclical blowups), so broader diversification is a risk management tool. Position sizes typically ranged from 0.25-2% of the fund. The portfolio was heavily tilted toward small and micro-cap industrials, specialty financials, technology components, and niche businesses. Sector exposure was broad. Turnover was moderate — Royce held positions for 2-5 years typically, sometimes longer. The overall approach was systematic and disciplined rather than high-conviction con...
Strong long-term record, especially from the 1970s through the early 2000s. The Pennsylvania Mutual Fund under Royce delivered annualized returns of approximately 13-14% over its first 30+ years, meaningfully outperforming the Russell 2000. Royce demonstrated the small-cap value premium effectively over multiple market cycles. However, like many value-oriented small-cap managers, performance in the 2010s was challenging as growth stocks dominated and the small-cap value factor underperformed dramatically. The Royce funds generally trailed their benchmarks during 2014-2020. Post-COVID recovery and the 2021-2022 value rotation helped somewhat. Royce's legacy is more about proving that small-cap value investing works over long periods than about generating spectacular short-term returns. He n...
Medium-high. Royce Funds published regular commentary and investor letters discussing their outlook and portfolio positioning. Chuck Royce himself was a thoughtful communicator, though not as prolific as some peers. The funds' holdings, performance, and strategy descriptions are available through standard fund reporting. 13F filings reveal portfolio positions. Now that the firm is part of Franklin Templeton, the transparency is institutional-grade. Royce's philosophical framework is well-documented through interviews, conference presentations, and his firm's publications. However, the sheer number of positions makes it hard to identify high-conviction ideas.
High. Royce has been a consistent and principled investor throughout his career. He invested his own money alongside his fund shareholders. The sale to Legg Mason was handled professionally, and he continued managing money rather than just collecting fees. No significant scandals, SEC actions, or ethical controversies are associated with Royce. He has been a significant philanthropist, particularly supporting arts organizations and his alma mater Brown University (the Royce Family Fund for Teaching). His fee structure was standard for active mutual funds — not cheap, but not extractive by industry standards. He built his reputation on steady, disciplined performance rather than self-promotion or marketing hype.
Royce's portfolios were filled with small and micro-cap names that most investors would not recognize: industrial companies like Quaker Chemical, Watts Water Technologies, CIRCOR International; specialty finance like Cohen & Steers, Evercore; technology components like MKS Instruments, II-VI Incorporated; niche businesses like Healthcare Services Group, Fossil Group, Century Aluminum. The portfolio was a 'who's who' of quality small-cap America — companies with $200M-$3B market caps, strong niches, and solid balance sheets.
Low-moderate relevance. Royce's philosophy — downside protection first, focus on balance sheet quality, patience with small-cap value — aligns directionally with our thinking about 'little chance of losing money.' His emphasis on buying below intrinsic value and focusing on asset-rich companies resonates. However, the extreme diversification (200-400 positions) is antithetical to our concentrated approach. Small-cap investing also requires specialized expertise and is harder to implement at scale. His returns, while solid over long periods, were not spectacular enough to suggest we should follow his specific positions. Best use: his philosophical framework on small-cap quality screening could inform our approach when we look at smaller companies.
Founded Whale Rock Capital in 2006. Based in Boston. Harvard Business School graduate. Built career focused on technology, media, and telecom sectors. Runs a crossover fund investing in both public and private tech companies. AUM estimated at $5-10B range. Known as one of the top-performing tech-focused hedge fund managers of his generation, with deep expertise in internet and software businesses.
Growth-oriented, concentrated tech investor. Focuses on TMT (Technology, Media, Telecom) sectors almost exclusively. Invests in both public equities and private companies (crossover fund structure). Seeks companies with large addressable markets, strong competitive positions, and durable growth trajectories. Willing to pay up for quality growth. More momentum/growth-oriented than value-oriented. Holds concentrated positions in high-conviction names. Believes in riding secular technology trends and backing category-defining companies.
Concentrated, growth-focused, tech-heavy. Typically 20-40 positions in public portfolio. Top 10 positions often represent 50%+ of portfolio. Heavy weighting toward mega-cap tech and high-growth software/internet companies. Crossover into private markets gives early access to pre-IPO companies. High portfolio turnover relative to value investors. Willing to size up aggressively in conviction names.
Strong long-term returns, particularly during tech bull markets. Has generated significant alpha in tech-heavy periods. Performance tends to be volatile given sector concentration. Outperformed during 2020-2021 tech boom. Likely underperformed during 2022 tech selloff given concentrated tech exposure. One of the better-regarded tech-focused hedge fund managers. Exact annualized figures not publicly disclosed but reputation suggests consistent outperformance over fund lifetime.
Low. Private hedge fund with minimal public disclosure. 13F filings provide quarterly snapshots of public holdings. Does not give public interviews frequently. Limited media presence. Investors receive detailed reporting but public information is sparse.
No known controversies or regulatory issues. Clean track record from an ethics standpoint. Maintains a low profile which makes assessment difficult, but absence of negative signals is positive. Institutional investors continue to allocate, suggesting satisfactory governance and compliance.
Historically heavy in mega-cap tech: Meta, Amazon, Microsoft, NVIDIA, Alphabet. Also known for positions in high-growth names like Uber, DoorDash, Snowflake, CrowdStrike, and various private tech companies. Portfolio shifts meaningfully quarter to quarter given growth focus and willingness to trade around positions.
Limited alignment. Sacerdote is a growth/momentum investor focused on tech who is willing to pay high multiples for growth. His approach is fundamentally different from our downside-first, floor-price philosophy. His tech sector expertise and concentrated style are superficially similar to our approach, but the underlying philosophy diverges significantly. His holdings overlap heavily with companies we analyze (Meta, etc.) but for different reasons. Useful as a signal of institutional conviction in specific tech names but not a philosophical match.
Wong Kok Hoi is the founder, executive chairman, and chief strategist of APS Asset Management, a Singapore-based independent asset management firm he founded in 1995. The firm celebrated its 30th anniversary in 2025. Wong is a CFA charterholder and was a Monbusho Scholar at Hitotsubashi University in Japan (a prestigious Japanese government scholarship for foreign students). He also completed the Investment Appraisal and Management Program at Harvard University. Before founding APS, he held senior positions at the Government of Singapore Investment Corporation (GIC — one of the world's largest sovereign wealth funds), Cititrust & Banking Corporation, and the Monetary Authority of Singapore (Singapore's central bank and financial regulator). This combination of central banking, sovereign we...
Wong's philosophy centers on deep fundamental research with an investigative, contrarian edge. Key elements: (1) 'In Search of Alpha' — APS's stated mission is identifying four different sources of sustainable alpha; (2) Investigative, independent research — the firm goes 'the extra mile' to understand companies, conducting proprietary research that goes beyond consensus analysis; (3) Focus on 'poorly researched' companies — APS targets informational advantages by analyzing companies that the market does not fully understand; (4) Risk management through research depth — rather than diversification as a risk management tool, Wong emphasizes reducing capital impairment risk through deeper understanding; (5) Contrarian orientation — willingness to take positions against market consensus when ...
APS runs multiple strategies across Asian markets. Key characteristics: (1) Long/short capability is a defining feature — Wong runs both long-only and long/short strategies, using short selling as both an alpha source and hedging tool; (2) Concentrated positions in highest-conviction ideas; (3) Geographic coverage spans China A-shares, Hong Kong, broader Asia, Japan, and Vietnam; (4) Employee-owned structure aligns management with clients — leadership has skin in the game; (5) Focus on mid-cap and under-followed names where informational advantages are greatest; (6) The Shanghai research office provides on-the-ground intelligence on Chinese companies; (7) Multi-strategy approach with different funds for different risk/return profiles. The long/short element is the most significant differen...
APS has operated for 30 years (1995-2025), making it one of the longest-running independent Asian-focused asset managers. Wong's track record has been mixed across different periods. His China expertise was a significant advantage during periods when China was growing and under-researched (early 2000s through mid-2010s). However, like all China-focused managers, APS would have faced significant headwinds during the 2021-2023 China regulatory crackdown and property crisis. The firm's long/short capability would have provided some downside protection during these periods compared to pure long-only managers. APS's longevity — surviving multiple Asian crises (1997, 2008, 2015, 2020-2023) as an independent employee-owned firm — is itself evidence of competence, as many Asian-focused asset manag...
Moderate transparency. APS is a private, employee-owned firm rather than publicly listed, so there is less mandatory disclosure than for listed companies like Value Partners or Sparx. The firm publishes thought leadership pieces, market commentaries, and presentations. Wong gives select interviews and speaks at industry conferences. The firm's website provides overview information about strategies and team but does not publish detailed performance data publicly. Position-level disclosure is limited — Asian hedge funds and asset managers generally have less transparency than US-based managers subject to 13F requirements. The employee-owned structure means there is no public financial reporting obligation. Overall, transparency is adequate for a private Asian asset manager but significantly ...
Good integrity indicators. The employee-owned structure aligns management interests with clients — Wong and his team invest alongside clients. The GIC and MAS background suggests professional training in institutional governance and risk management. 30 years of continuous operation without scandal or regulatory issues is a positive signal. The establishment of a Shanghai research office in 2002 — well before many Western firms committed to on-the-ground China research — shows genuine commitment to understanding what they invest in. The firm's emphasis on investigative research and going the 'extra mile' suggests a commitment to truth-seeking rather than narrative-chasing. No ethical controversies or regulatory issues are publicly associated with Wong or APS. The main concern is the limited...
APS's specific holdings are not widely disclosed due to the firm's private status and different disclosure regimes in Asia. The firm invests across China A-shares, Hong Kong-listed Chinese companies, broader Asian equities, Japanese equities, and Vietnamese equities. Holdings would include a mix of established Chinese/Asian companies and under-followed mid-caps where the firm believes it has informational advantages. The Shanghai research office suggests significant China exposure. The long/short strategies would include both long positions in undervalued companies and short positions in overvalued or problematic companies, but specific names are not publicly available.
Moderate relevance with some notable limitations. Positives: (1) Wong's investigative, contrarian approach to research aligns with our emphasis on understanding businesses deeply; (2) His focus on 'poorly researched' companies and informational advantages resonates with our goal of finding overlooked value; (3) His 44 years of China experience is genuinely valuable insight if/when we look at Chinese equities; (4) The employee-owned, skin-in-the-game structure is exactly the alignment we look for; (5) His GIC/MAS background provides institutional credibility. Limitations: (1) The long/short strategy is fundamentally different from our long-only approach — we do not short; (2) APS is primarily Asia/China focused, limiting direct applicability to our current universe; (3) Low transparency mak...
Born 1944 in New York City. Graduated from the University of Rochester and Harvard Law School. Worked as an attorney before founding Elliott Management Corporation in 1977 with $1.3 million in capital. Net worth estimated at $6-8 billion. Elliott now manages approximately $65-70 billion in AUM, making it one of the largest and most powerful activist hedge funds in the world. Singer is known as an intensely private, intellectually rigorous, and often feared investor. Elliott's approach spans distressed debt, activism, mergers arbitrage, and multi-strategy investing. Notable for his tenacious pursuit of returns — most famously, his 15-year legal battle with Argentina over defaulted sovereign debt, which ultimately resulted in a full payout. Elliott operates globally with offices in New York,...
Elliott Management is a multi-strategy fund that combines several approaches: (1) Activist equity investing — taking positions in companies and pushing for operational changes, strategic alternatives (sales, mergers, spinoffs), capital returns, or management changes. (2) Distressed debt — buying debt of troubled companies at deep discounts and either working through restructuring to recovery or converting to equity. (3) Merger arbitrage — taking positions in announced deals and sometimes pushing for better terms. (4) Event-driven — exploiting mispricings around corporate events. Singer's overarching philosophy is absolute return orientation — he aims to make money in all market environments with low correlation to equity markets. Elliott's risk management is sophisticated, with careful pos...
Highly diversified across strategies and positions. Elliott's 13F typically shows 50-100+ positions across many sectors, but the equity portfolio is only one part of the fund. Significant capital is deployed in credit, distressed debt, merger arbitrage, and other strategies not visible in 13F filings. Within the equity portfolio, positions can be quite large — Elliott has taken multi-billion dollar stakes in companies like AT&T, Twitter, SAP, SoftBank, Marathon Petroleum, and Salesforce. The fund's size ($65-70B AUM) means they can take very large positions. Holdings span the full market cap spectrum from mid-cap to mega-cap. Geographic diversification is broad — Elliott is active in the US, Europe, Asia, and emerging markets. Uses extensive hedging, options, and derivatives. Not a concent...
Exceptional and remarkably consistent. Elliott Management has generated approximately 13-14% annualized returns net of fees since inception in 1977 — nearly 50 years with only two down years (minor losses in 1998 and 2008). This consistency is extraordinary in the hedge fund industry. The fund has compounded capital at rates that rival long-term equity market returns but with dramatically lower volatility and drawdowns. Notable activism wins: AT&T (pushed for strategic changes including WarnerMedia separation), Twitter (pushed for CEO change, board seats), SAP (operational improvements, margin expansion), Marathon Petroleum (spinoff of Speedway), Salesforce (cost discipline campaign), SoftBank (pushed for asset sales, buybacks), Hitachi (governance improvements). The Argentina sovereign de...
Low to moderate. Elliott is notoriously private. Singer rarely gives interviews and the firm publishes limited public information about its strategies, positions, or performance. 13F filings provide some equity position visibility, but the multi-strategy nature of the fund means 13F data represents only a fraction of total activity. Elliott's investor letters are not publicly available (unlike some peers). When Elliott launches activist campaigns, their public filings and presentations provide insight into specific theses, but the broader portfolio strategy remains opaque. The firm's size and complexity make it very difficult for outsiders to understand the full picture. Singer has been more visible in recent years through political activities but remains tight-lipped about investments.
Complex picture. On one hand, Singer has an impeccable legal and ethical record — no SEC enforcement actions, no fraud allegations, no accounting issues in nearly 50 years of operation. He is known for rigorous risk management and honest dealing with investors. On the other hand, Elliott's aggressive tactics have drawn controversy: the Argentina sovereign debt battle was seen by some as 'vulture capitalism' (buying distressed sovereign debt and pursuing maximum recovery at the expense of a developing nation's population). Elliott has also been criticized for aggressive activism tactics in some campaigns. Singer's significant political donations (including to causes opposed by many in the investment community) are a matter of public record. Some view Elliott as too aggressive and litigious....
Current/recent major equity positions: various large-cap positions (Elliott's 13F changes frequently). Recent major activism campaigns: Salesforce (2023, cost discipline), Starbucks (2024, pushed for changes), Texas Instruments (2024), SoftBank, Phillips 66. Historical notable plays: AT&T (WarnerMedia separation), Twitter (CEO change, later Musk acquisition), SAP (operational turnaround), Marathon Petroleum (Speedway spinoff), Hitachi (governance), NRG Energy, Cabela's (sale to Bass Pro), Athenahealth (sale), Citrix (take-private). Significant distressed debt activity (not visible in 13F) including sovereign debt (Argentina, Peru, Congo).
Low relevance despite excellent track record. Elliott's multi-strategy hedge fund approach is fundamentally different from our long-only, concentrated, long-term philosophy. Their returns come from a combination of activism, distressed debt, merger arbitrage, and hedging — none of which we practice. The fund's low transparency makes it difficult to follow or learn from their specific positions. Their activism campaigns can provide useful analytical perspectives on specific companies (e.g., the Salesforce or AT&T theses), but the positions change frequently and are part of a complex hedged portfolio. Elliott's consistency is admirable but achieved through diversification across strategies rather than concentrated long-term conviction. Singer's approach to risk (absolute return, hedging, mul...
Two Sigma Investments was founded in 2001 by John Overdeck (born 1969) and David Siegel (born 1961). Overdeck is a mathematics prodigy (silver medal at the International Mathematical Olympiad at age 16) who worked at D.E. Shaw and Amazon before co-founding Two Sigma. Siegel holds a PhD in computer science from MIT and also worked at D.E. Shaw. The firm manages approximately $60+ billion in AUM and is headquartered in New York City. Two Sigma distinguishes itself from other quant firms by its heavy emphasis on machine learning, artificial intelligence, and distributed computing — the firm describes itself as a 'technology company that applies a rigorous, scientific method-based approach to investment management.' The firm employs approximately 2,000+ people, with a significant proportion be...
Two Sigma's philosophy centers on the belief that large-scale data analysis, machine learning, and distributed computing can identify patterns and relationships in financial markets that are invisible to human analysis. The firm processes enormous datasets — including alternative data sources like satellite imagery, credit card transactions, social media sentiment, and weather data — through proprietary machine learning models. Unlike Renaissance (which predates modern ML), Two Sigma was built from the ground up around machine learning and AI. The firm's approach is highly empirical: they generate hypotheses from data, test them rigorously, and deploy capital only to strategies with strong statistical evidence. Two Sigma is more willing than most quant firms to discuss its general approach...
Two Sigma's portfolio is highly diversified across thousands of positions in equities, futures, options, and other instruments globally. The firm runs multiple strategies including statistical arbitrage, macro, and engineered finance. Turnover is high in systematic strategies but varies across the firm. Two Sigma uses moderate to significant leverage. The 13F filings show a very large, diversified equity portfolio with hundreds of positions — recent top holdings have included large positions in tech mega-caps and broad market exposure. The portfolio is constructed to be market-neutral or directionally flexible depending on the strategy. Like other quant firms, the 13F represents only a partial view of the overall portfolio. Two Sigma Ventures invests in early-stage technology companies, pa...
Two Sigma's track record has been strong overall, though with some variability. The firm's flagship funds have generally produced mid-to-high single-digit to low double-digit annual returns with low correlation to broader markets. The firm navigated 2008 relatively well compared to peers, and has generally performed consistently across market environments. Two Sigma's AUM has grown from approximately $6 billion (2008) to $60+ billion (2024), reflecting both strong performance and investor confidence. However, some strategies have had periods of underperformance — the firm reportedly had a difficult 2019 and faced some challenges adapting its models to the COVID-era market regime. The venture capital arm has had notable successes including early investments in Peloton, Flatiron Health, and ...
Two Sigma is more transparent than most quant firms about its general approach and philosophy, though specific strategy details remain proprietary. The firm publishes a blog (Two Sigma Insights) and research papers, and its leaders occasionally give public talks and interviews. The firm is active in the open-source community, contributing to projects like Beaker (a data science platform) and sharing some research. Overdeck and Siegel have given several notable interviews discussing the role of AI and data science in investing. Two Sigma's emphasis on its scientific and technological culture is well-documented. The firm is not as transparent as AQR (which publishes detailed factor research), but significantly more open than Renaissance or D.E. Shaw. The venture capital arm is reasonably tra...
Two Sigma has a generally positive reputation for integrity. The firm has not been involved in major scandals or regulatory issues. Both founders are well-regarded in the quantitative finance and technology communities. The firm invests significantly in employee development and scientific research. Two Sigma's philanthropic efforts include the Two Sigma Impact (social impact investing), and both founders are active philanthropists — Overdeck founded the Overdeck Family Foundation focused on education. One notable legal issue: in 2019, Two Sigma sued a former employee over alleged theft of proprietary code, which is relatively standard for quant firms protecting IP. The firm's expansion into insurance technology and venture capital suggests genuine interest in applying quantitative methods ...
Two Sigma's 13F shows an extremely diversified portfolio with hundreds of positions. Recent top holdings have included significant positions in Nvidia, Microsoft, Amazon, Meta, Apple, Alphabet, and other tech mega-caps, along with broad exposure across sectors including healthcare, financials, consumer, and industrials. The portfolio also shows large options positions. Two Sigma Ventures has invested in notable technology companies including those in the AI/ML space. As with other quant firms, the 13F represents only the long equity portion of a multi-asset portfolio and individual positions reflect systematic model outputs rather than fundamental conviction. Following Two Sigma's 13F for investment ideas would not be useful.
Two Sigma has the highest relevance of any firm in this group, though it is still low in absolute terms. The relevance comes from three factors: (1) Two Sigma's heavy investment in AI/ML is directly aligned with our AGI thesis — the firm is literally building AI systems for investing, giving them firsthand knowledge of AI capabilities and limitations. (2) Two Sigma Ventures invests in AI companies, providing insight into the AI startup ecosystem. (3) The firm's use of alternative data and machine learning could inform our own data-gathering approach (e.g., using our lightweight scoring pipeline). However, practical relevance remains low — Two Sigma's edge is institutional scale, proprietary data, and computational infrastructure we cannot replicate. Their investment ideas are not transpare...
Leopold Aschenbrenner is a young AI researcher (born ~2000) who became one of the most influential voices on AGI timelines. He studied economics at Columbia University, graduating at age 19, and was a research fellow at the Global Priorities Institute at Oxford before joining OpenAI's Superalignment team under Ilya Sutskever. In mid-2024, he was fired from OpenAI after raising internal concerns about the company's security practices; he has described himself as a whistleblower. Shortly after, he published 'Situational Awareness: The Decade Ahead,' a sprawling ~165-page essay that became the most widely-read and debated analysis of AGI timelines and implications in 2024. Following the essay's viral success, Aschenbrenner reportedly raised hundreds of millions of dollars for an AI-focused in...
Aschenbrenner is not a value investor in any traditional sense. His investment thesis is entirely forward-looking and based on a single, high-conviction macro prediction: AGI will arrive by 2025-2027, with superintelligence following within 1-2 years after that. His 'Situational Awareness' essay lays out the case with detailed analysis of compute scaling trends (~0.5 orders of magnitude annually), algorithmic improvements, and the 'unhobbling' gains from better scaffolding and tool use. He argues that the path from GPT-2 to GPT-4 (preschooler to smart high-schooler) took 4 years, and comparable progress toward human-level AI will continue through 2027. Once AGI is achieved, he predicts hundreds of millions of AI agents could automate AI research itself, compressing a decade of algorithmic ...
Limited public information on his fund's specific portfolio structure. Based on his thesis and reported fundraising (hundreds of millions), his investments are likely concentrated in: (1) compute infrastructure -- data centers, GPU/chip supply chain, cooling/power systems; (2) energy -- electricity generation and transmission capacity needed for massive AI scaling; (3) possibly direct AI company equity or secondaries. His approach is inherently concentrated and thematic -- he is making a single macro bet (AGI is imminent) and investing in the infrastructure required for it. This is closer to venture capital or thematic growth investing than value investing. He has no public 13F filing, and the fund structure is likely a private fund (LP structure). There is no evidence of value discipline,...
No meaningful public investment track record. His fund was established in 2024, making it less than 2 years old. His intellectual track record is more notable: the 'Situational Awareness' essay has been remarkably prescient in some respects (the AI investment surge, the national security discourse around AI, the scaling laws continuing to hold). However, his most aggressive prediction -- AGI by 2025-2027 -- has not yet been validated or falsified. The essay generated enormous attention and is considered one of the most important pieces of AI analysis written, regardless of whether its specific timeline predictions prove correct. His fundraising success suggests institutional credibility, but there is no track record of generating investment returns.
Moderate-high on intellectual framework, low on investment specifics. The 'Situational Awareness' essay is freely available and remarkably detailed -- Aschenbrenner lays out his reasoning with specific technical arguments, making it easy to evaluate his thinking. However, his investment fund is private, with no public holdings disclosures, performance data, or investor letters. He is active on social media (Twitter/X) and gives occasional interviews and podcast appearances, but these focus on AI predictions rather than investment specifics. Fee structure and fund terms are not publicly disclosed.
Appears high but hard to fully assess given short public career. His whistleblowing at OpenAI -- raising concerns about security practices at personal cost (he was fired) -- suggests intellectual courage and willingness to take unpopular positions. His essay is intellectually honest in that it explicitly states its assumptions and allows readers to disagree on specific inputs while following his logic. He does not appear to be a hype merchant -- his tone is analytical and concerned rather than promotional. However, there are legitimate questions about potential conflicts of interest: he published a widely-read essay predicting a massive AI infrastructure buildout, then raised a fund to invest in exactly that buildout. Whether the essay was genuine analysis that led to investment conviction...
No specific public holdings known. Based on his thesis, likely exposed to compute infrastructure (data centers, NVIDIA supply chain, energy/power generation), possibly AI lab equity or related companies. His fund was reportedly structured around the core thesis of massive infrastructure investment needed for AGI.
Leopold Aschenbrenner is extremely relevant to us intellectually but has minimal relevance as an investment guide. His core thesis -- AGI by ~2027, with massive infrastructure investment required -- aligns closely with our own AGI-by-2030 assumption. His essay is essential reading for anyone with our thesis. His analytical framework for thinking about compute scaling, algorithmic gains, and the intelligence explosion is the most rigorous public treatment of these topics. HOWEVER, his investment approach is the opposite of ours: he is making a forward-looking, thesis-driven bet with no value discipline, no downside protection, no balance sheet analysis, and no floor price methodology. He is not looking for 'little chance of losing money' -- he is making a high-conviction directional bet on ...
Marc Andreessen (b. 1971) co-created Mosaic (first widely-used web browser) and co-founded Netscape (IPO'd 1995, acquired by AOL 1999), LoudCloud/Opsware (sold to HP for $1.6B in 2007), and Ning. He is one of the most influential technologists of the internet era. Ben Horowitz (b. 1966) was Andreessen's co-founder at LoudCloud/Opsware and is the author of 'The Hard Thing About Hard Things,' a widely respected book on startup management. Together they founded Andreessen Horowitz (a16z) in 2009, which has grown into one of the most influential venture capital firms globally with approximately $42+ billion in AUM across venture, growth, crypto, bio, games, and infrastructure funds. a16z pioneered the 'platform' model of VC, building a massive internal team of operating partners, recruiters, m...
a16z's philosophy is fundamentally growth-oriented and technology-optimistic: (1) 'Software is eating the world' — Andreessen's famous 2011 essay arguing that software companies would dominate every industry. This thesis has largely proven correct and continues to drive a16z's investment focus. (2) Founder-first — strong preference for backing exceptional founders, even in competitive or uncertain markets. a16z gives founders significant operational support through its platform model. (3) Category creation — invest in companies creating new markets rather than competing in existing ones. (4) Technology conviction — a16z is willing to make large, contrarian bets on emerging technology paradigms (mobile, cloud, crypto, AI) before consensus forms. (5) Power law investing — VC model where a fe...
Highly diversified across hundreds of portfolio companies, spanning: enterprise SaaS, consumer internet, fintech, crypto/web3, bio/health, AI/ML, games, American Dynamism (defense/infrastructure), and more. Individual funds may hold 30-50+ companies. a16z's portfolio is essentially a broad index of venture-backed technology innovation. While individual positions can be large (they led Coinbase's Series B, invested early in Facebook, Instagram, GitHub, Airbnb, Stripe, Roblox, etc.), the overall portfolio is extremely diversified by VC standards. In public markets, a16z's 13F filings show positions in growth-stage tech companies, but these are typically small relative to total AUM and often represent pre-IPO investments held through listing. a16z does not practice concentrated public equity ...
Strong in aggregate with notable hits and significant misses. Major wins: (1) Facebook/Meta — early investor in 2009 ($27.5M for 2.4% stake), worth billions at IPO, (2) Instagram — invested before Facebook acquisition, (3) GitHub — invested pre-Microsoft acquisition ($7.5B), (4) Coinbase — lead Series B investor, massive returns at IPO despite subsequent volatility, (5) Airbnb — early investor, strong returns at IPO, (6) Stripe — early investor in one of the most valuable private companies, (7) Roblox — strong returns through IPO, (8) Okta, PagerDuty, Databricks, Figma (before Adobe acquisition attempt), Anduril. Misses and controversies: (1) Crypto fund performance has been highly volatile — a16z's crypto funds invested at peak valuations in 2021-2022 and experienced significant markdowns...
Low-to-moderate. As a registered investment advisor, a16z files 13F reports showing public equity holdings, but these represent a small fraction of total portfolio activity. The firm does not publicly disclose fund-level returns, individual investment performance, or management fee/carry structures. a16z IS very active in public discourse through: (1) extensive blog/essay output (Andreessen is prolific), (2) the a16z podcast and newsletter, (3) conference appearances, (4) Andreessen's active social media presence (Twitter/X). However, this public engagement is largely about promoting their worldview and thesis (pro-technology, pro-AI, pro-crypto) rather than disclosing investment performance or portfolio details. There is a meaningful gap between a16z's high public profile and actual inves...
Mixed with notable concerns. Positives: (1) Andreessen and Horowitz have built a genuinely influential institution that has helped create enormous value through its portfolio companies, (2) The platform model genuinely helps founders beyond just providing capital, (3) Horowitz's writing and speaking demonstrate thoughtful, experience-based wisdom about company-building. Concerns: (1) a16z's aggressive promotion of crypto/web3 investments while being the largest institutional holder creates potential conflicts of interest — they are essentially talking their book, (2) The 'Techno-Optimist Manifesto' and related advocacy represents ideology as much as investment analysis — Andreessen has taken increasingly extreme positions that prioritize technological acceleration over safety consideration...
Current and notable investments include: (Public) Meta/Facebook (Andreessen board seat), Coinbase, Roblox, various crypto tokens and DeFi protocols. (Late-stage/pre-IPO) Stripe, Databricks, Anduril Industries, Neuralink, Mistral AI, Character.AI (before Google deal), ElevenLabs, various AI infrastructure companies. (Crypto) Solana, Optimism, Aptos, Uniswap, Compound, MakerDAO, OpenSea, Yuga Labs (Bored Ape Yacht Club), Flow blockchain, Worldcoin, multiple other token and crypto equity positions. (Enterprise) Databricks, Fivetran, dbt Labs, Cribl. (AI) Mistral AI, Character.AI, ElevenLabs, Cohere (rumored), numerous AI application companies. a16z has been one of the most active investors in AI/AGI-related companies through 2024-2025.
Moderate relevance with important caveats. Relevance factors: (1) a16z is arguably the most AGI-aware investor on this list — their entire thesis is built around technology transformation, and they have made massive AI bets. This aligns with our AGI-by-2030 assumption. (2) Their 'software is eating the world' thesis helps identify which sectors face disruption and which software companies benefit — directly useful for our analysis framework. (3) Andreessen's technology insights (not his political views) provide genuinely useful frameworks for thinking about technology value creation. (4) Their AI portfolio company picks (Mistral, Anduril, Databricks) signal where smart money sees AGI value creation. Limitations: (1) VC model is fundamentally different from our approach — power law investin...

| 111 | Michael Burry Scion Asset Management | 5.05 | Legendary for The Big Short but post-2008 career marked by high turnover, failed macro calls, AI skepticism, and near-zero transparency - antithetical to our patient, AGI-forward approach. |

| 124 | Leon Black Apollo Global Management | 4.60 | Brilliant distressed debt investor with an exceptional early track record, but the Epstein scandal, fee-extracting fund model, credit-focused strategy, and minimal AI positioning make Apollo's approach fundamentally misaligned with our concentrated long-only public equity philosophy. |

| 132 | David Winters Wintergreen Advisers | 4.25 | Mutual Series pedigree and principled governance activist (notably Coca-Cola), but Wintergreen Fund's sustained underperformance, high fees, and eventual closure make him a cautionary tale rather than a model to follow. |
| 133 | Kyle Bass Hayman Capital Management | 4.25 | Brilliant one-hit subprime trade followed by a decade of underperforming macro bets; derivative-heavy style is fundamentally incompatible with our approach. |
| 134 | Edouard Carmignac Carmignac Gestion | 4.15 | Pioneering French macro-driven flexible allocator with a strong pre-2010 record that faded — approach is too diversified, active, and macro-driven to be relevant to our concentrated value philosophy. |

| 140 | Sardar Biglari Biglari Holdings | 3.75 | Self-styled Buffett imitator who copies the words but not the character -- massive self-enrichment through embedded hedge fund fees, poor returns, governance entrenchment, and declining businesses make this the anti-model for principled value investing. |
| 141 | Michael Saylor MicroStrategy / Strategy | 3.70 | A single-asset, leveraged Bitcoin maximalist with a past accounting fraud settlement -- represents the antithesis of our value-oriented, downside-protection-first investment philosophy. |
