Positions are from the latest 13F-HR (period end 2026-06-30). Weights are calculated: position value ÷ the 13F book. Schedule 13D/13G stakes are merged in when present (shares and percent of class, no dollar value). Chg Shares and % Chg compare with the adjacent prior quarter's 13F only. % Out is either calculated (position shares ÷ issuer shares outstanding from the issuer's XBRL cover page; weighted-average basic shares as a fallback) or reported (percent of class on a Schedule 13D/13G newer than the 13F period) — hover a value for its source and date. Unavailable figures show “—”, never an estimate. Methodology
