Market-cap percentage moves are computed from current market cap and historical close prices using the current share base. "What we own" and "What we owned before" are read live from the family portfolio database (tickers only), so they change by themselves when the portfolio does. The table API batches Yahoo quote and spark requests and caches the response for 10 minutes in D1; chart data is fetched only after a row click and is cached separately for 15 minutes. For ETF benchmarks such as VOO, the value column uses net assets and the percentage move is the ETF price move.
