About this data
The quarter. Every module here is measured at 2026-06-30 (Q2 2026) — the newest quarter whose 45-day filing window has closed and whose roster of managers is complete. A quarter that is closed but only partly reported is never used as the current one, because absent managers would read as sales.
Some firms report more than one portfolio. These appear separately and are never added together.
Weight. A position's weight is its long value divided by the manager's total disclosed long-equity value for that quarter. Options are excluded from the numerator; holdings we could not match to a security we cover are still counted in the denominator and shown under their filed name. A change in weight is given in percentage points and moves with price as well as with trading — it is not a measure of how much a manager bought.
What 13F does not say. A 13F covers US-listed equities and equity options at a quarter end, filed up to 45 days later. It is not the firm's whole portfolio, and a manager's absence from a quarter is not a sale. Share changes are shown only after adjusting for splits; where the adjustment could not be confirmed, the change is withheld rather than published.
