Research only. This dashboard summarizes delayed public SEC 13F filings as of the reporting period. It is not personalized investment advice, contains no buy/sell/hold recommendations, and does not represent current holdings. 13F filings have a 45-day lag and cover only Section 13(f) reportable U.S. long equity positions — no shorts, hedges, cash, options strategy, foreign-listed shares outside scope, or private holdings. Always verify against the original EDGAR filing.

Context (not from the filing itself): the named exits overlap substantially with positions previously associated with sub-advisor Todd Combs, who left Berkshire for JPMorgan in December 2025 (per WSJ, relayed via ZeroHedge). The 13F does not attribute holdings to individual sub-advisors.

13F limitations — applies to every conclusion above

45-day lag. Q1 2026 holdings were filed May 15, 2026 — already 6+ weeks old at publication and 8+ weeks old today. Treat as "reported at quarter end," not "owned today."
Section 13(f) scope only. Excludes shorts, cash, U.S. Treasury holdings (Berkshire's >$300B cash/Treasury pile is reported elsewhere), foreign-listed shares outside scope (e.g., the Japanese trading-house investments), private holdings, and most derivatives.
Long, partial-portfolio data. No shorts. No full options strategy. No hedges. No net exposure.
Amendments. 13F-HR/A filings can revise positions retroactively. None observed for these two periods as of this run.
Confidential treatment. Berkshire has historically requested confidential treatment for select accumulating positions; those may be omitted until later disclosure.
Manager identity. Berkshire Hathaway Inc. files one consolidated 13F covering many related "other managers" listed in the filing. Standalone subsidiary filings should not be combined without source-by-source matching.
CUSIP → ticker mapping. Top-10 mappings are high-confidence. Share-class rows (LEN-B, LLYVK vs. LLYVA) and ADRs (DEO) require CUSIP-first matching.
Value ≠ trade size. Value change blends price action with trading. Share change is the cleaner trade signal.
Data-quality note for this run. Direct SEC XML extraction was not completed in this session due to network constraints; top-10 share counts were sourced from 13Radar.com and Giantsight, both of which ingest the SEC information table directly, and cross-verified against Seeking Alpha and Tipranks. The Constellation Brands (STZ) trim row is preliminary pending direct XML reconcile. A full direct-XML reconcile is the recommended next research step.

Suggested follow-up research

Pull the raw SEC information tables for both periods and reconcile each row of this dashboard against the XML.
Read the Berkshire Q1 2026 10-Q for cash position, Treasury holdings, buyback activity, and operating-segment performance — the 13F shows the equity sleeve only.
Watch for an Annual Letter (typically late February the following year) and any Berkshire Annual Meeting commentary for Greg Abel's first sustained public framing of the equity strategy.
Track the next 2–3 quarters of 13Fs to test whether the Q1 2026 exit list represents a durable style change or a one-time clean-up of legacy positions.
For each top-10 name, separately read the company's most recent 10-K risk factors and proxy — Berkshire's filing tells you position size, not the underlying business case.
Use 13F overlap as a watchlist input, not a buy signal — Berkshire's cost basis, holding horizon, and tax position differ materially from a retail investor's.
