* Estimated cost basis: 13F filings do not disclose average purchase prices. For new positions since 2024 Q9, we estimate the cost basis using quarterly average prices. Positions with partial sales are marked unavailable. Returns based on these estimates are for reference only.

This page mechanically processes original 13F/HR filings on SEC EDGAR. Holdings are reported as of quarter-end and filings are submitted within 45 days, so actual holdings may differ. Coverage of options, derivatives, foreign equities and warrants may be limited. Do not rely on this page alone for investment decisions; verify the original filings at SEC EDGAR.
