How it is worked out
  1. From the quarter's end a year ago, each quarter's 13F is held, weighted by value, to the next quarter's end; the latest one to the latest close. The quarters compound.
  2. Long stocks and ETFs only: no options, bonds, cash, trades within a quarter or dividends; spin-offs are not adjusted for.
  3. Quarter-end prices come from the 13F filings themselves (value ÷ shares); what they cannot tell (a holding sold, a split, a big move) is checked against Tiingo's closes, and the latest prices are Finnhub's.
  4. Holdings with no price are left out and the rest re-weighted. Under 80% priced, or while holdings are still being checked, no figure is shown.
  5. A simulation from public filings, not the investor's actual performance.

Holdings at the end of June 30, 2026. 13F filings are due 45 days after a quarter ends, so they are one to four months old.
