All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
