What 11 large investment managers reported holding, taken from their own SEC Form 13F-HR filings. Newest report period: 30 Jun 2026.
A Form 13F is a quarterly snapshot, not a live portfolio: a manager reports the US-listed long positions it held on the last day of a quarter, and may file up to 45 days after that quarter ends. Positions can have changed since. Short positions, most non-US holdings and cash are not reported at all.
These are the 11 managers whose filings we ingest — not the full 13F universe, which runs to thousands of filers. "Most held" on this site means most held among these 11.

Companies held counts distinct issuers, not filed lines: a manager commonly reports one company across several lines, one per sub-entity or share class.
Informational only — NOT financial advice. Holdings are self-reported on SEC Form 13F-HR and are a delayed quarterly snapshot, not a record of trades. A change between two reports is a change in a reported position, not a same-day purchase or sale, and it is not a recommendation to do the same.
