The books most like this one

Among the managers whose filings are on file, at Q2 2026. Overlap is the share of the two books that is the same: for every stock both list, the smaller of its two weights, added up. Two books can overlap because both own the largest companies; it says nothing about whether the managers agree.

The filings behind it

Every quarter above is one 13F holdings report, with any amendment the filer made to it applied in the order it was filed. Where the reporting entity changed, each quarter keeps the filer that actually reported it.

Reading this record

A 13F lists US-listed long equity and options at the quarter end, filed up to 45 days later. It shows what was held, not when it was bought or at what price, and nothing short. Where a quarter lists only the largest positions, a name missing from it may still be held below that range; the counts of what was opened and sold always cover the whole filing.
