About this data
Figures are parsed from BUFFETT WARREN E's Form 4 filings on SEC EDGAR (CIK 315090) and cover open-market purchases (transaction code P) — grants, option exercises, and sales are excluded, which is why totals here can differ from raw filing counts. Every row links to its source document.
This page is informational and reflects public filing data. It is not investment advice.
