As of Sep 15, 2026. 197 parsed trades. Ranks use three-year return.
Returns use correctly parsed individual-stock holdings, purchases and sales, with Tradier prices for unsold positions. Bounded reported amounts use their midpoint; trades reported as “over $5 million” use $5 million. Daily returns exclude cash contributions and holdings-value reconciliations. Sale proceeds remain as cash. Unparsed records and entries without usable amounts or prices are omitted; no missing trades or holdings are invented. Sales can only reduce observed holdings. The dates on each card show the available calculation period, which can be shorter than the requested period. These are estimates of the parsed portion of the portfolio, not verified brokerage returns.
Last reported holdings valued Dec 31, 2025. Original disclosure ↗. These are reported positions, not a live account balance.
This extraction is incomplete or awaiting reconciliation. The source may contain additional holdings.
