Q2 2026 13F: 27 holdings worth about $665.1M; that quarter 0 new, 0 added, 27 trimmed, 11 sold out.
13F lists only long positions in US-listed stocks (and some ETFs and convertibles); short positions, cash, bonds, shares listed outside the US and private companies are not shown, so this is not the giant’s whole portfolio.
Why This Giant Is Included
- Rule numbers (Q2 2026): 27 holdings, top 10 = 62%, stocks $0.7B, options 0%; all four rules met

How to Read This

Est. average cost: shares bought each quarter × (start + end price) ÷ 2, weighted; trims do not change the cost. Positions held before Q1 1999 (or the giant’s earliest electronic filing) start from that quarter’s price and are marked ‘start point’. vs cost = quarter-end price ÷ est. average cost − 1, excluding dividends.

Large Positions Sold Out
Positions that once made up 2% or more of the portfolio and were later sold out (latest 40): holding period and what became of the company, without profit or loss.
How to Read This
Sold out means the holding no longer appears on the 13F: it may have been sold, or the company was acquired or delisted. Company status is checked only for companies the giants together once held $100M or more of, from the company’s own SEC filings (for example 8-K item 1.03 = bankruptcy filing); a dash means not checked.
