Super-investor holdings · 2026 Q2

Source: SEC Form 13F filings for the quarter ended Jun 30, 2026. Change labels compare each fund’s 2026 Q2 filing with its previous filing. 13F filings cover long positions only and arrive up to 45 days after quarter-end. Fund counts here aggregate every share class mapped to this ticker; research headlines cite filer counts as they stood at publication, so a count here can differ from a headline by a holder (see Methodology, "How holder counts are counted").
