Warren Buffett — Berkshire Hathaway

A SEC EDGAR (13F-HR) + NYSE (BRK.B) ↗ Buffett controls Berkshire since 1965 (~61y); 13F series since the form exists

The share-price record is exchange-verified daily — the strongest format in the catalogue. The 13F equity book is a sworn SEC filing, but quarterly, up to 45 days lagged, long-US-only: a regulatory window, not the whole book.

Asset focusUS equities (13F book) inside a listed conglomerate — insurance, railroads, energy, operating businesses
StyleConcentrated long-term value investing; the equity book is disclosed quarterly by regulation, the business compounds behind a listed share
StandingThe most-watched 13F filer in the world; the February/May/August/November filing dates are market events in themselves

Closelook Rating v1 — Strong

Scored on the NAV-verified series (BRK-B, 2022-10-03 → 2026-10-21), not the person. Evidence length dampens short windows; the verifiability basis caps the score at 100. Published-method opinion over sourced facts — the full formula. A diary lens, not advice.

The Closelook read

The reference record of the catalogue: six decades of exchange-verified compounding behind a listed share, plus the quarterly regulatory window into the equity book that every copy-portfolio in the world watches with a 45-day lag.

Berkshire shows what the two layers of a filing-based record are worth. The share price is a complete, daily, exchange-verified record of the whole business — grade A without qualification. The 13F is something else: a sworn but lagged snapshot of the long US equity book only, with no shorts, no cash, no non-US holdings. Anyone copying it trades on information that is 45 to 135 days old. That gap — verifiable record versus tradeable signal — is the core distinction this catalogue exists to make.
