What this covers
Form 13F covers long positions in US-listed equities and listed options. Short positions, cash, bonds, foreign-listed holdings and most derivatives are outside it, so this is a partial view of the manager rather than their portfolio. Managers file within 45 days of quarter end, so holdings are a snapshot of Jun 30, 2026 that reached the public later. The figures are self-reported by the filer. Where a manager filed an amendment, the amended report is the one used here, and a manager filing through several entities is aggregated into one book.
