Sector is classified on each name's CURRENT fundamentals, not point-in-time — apparent sector drift can reflect the market re-rating a holding, not a manager trade. 13F is a lagged quarterly snapshot of long positions in US-listed securities only — foreign companies held via a US listing or ADR ARE included, but shares listed only on non-US exchanges (plus shorts, options and cash) are not. Latest quarter: 97.2% of the book is classified (unclassified names are still shown).

Similar managers — “Similar” = same top sector (Financials) + closest 13F size, self excluded; NOT a style or performance match, and a filer whose real business is elsewhere (shorts, private, non-13F) can still surface.
Also hold BRK.B — other Section 13(f) filers reporting a long position in this book's largest tickered holding for 2026-Q1. Lagged quarterly filings (up to 45 days after quarter-end); “% of shares out” is omitted where the reported share count can't carry it.
