Holder counts and values reflect the most recent SEC Form 13F filings, through the quarter ended 2026-03-31. Source: SEC EDGAR. A 13F shows only long US-listed positions and can lag the real portfolio by up to 45 days, so this is disclosed long ownership, not a complete picture.

Early quarters may understate holder counts due to data backfill — read the slope with care.
