What institutions reported holding

Search 292,522 reported position rows across 20 reporting entities and their collected quarters. Explore the holdings behind the names.

Collection dates and how to read these holdings

Partial manager coverage. Form 13F reports quarter-end holdings, usually filed later; not exact trades, transaction dates, current portfolios or ETF constituent data. Short positions, some securities, confidential holdings and unreviewed amendments may be absent. CUSIP and issuer names are preserved as filed; ticker/issuer-CIK matching is not inferred. Values use the SEC filing-date format (USD from January 3, 2023; thousands of USD before). Available valid filings are searchable even without comparison quarters. Combination reports and confidential-omission flags describe incomplete reported portfolios; only disclosed positions are shown, with no inferred missing holdings. Separate reporting entities remain separate.

47 source-checked filings. A reported portfolio snapshot—not executed trades. Histories may be incomplete; missing data does not mean no holdings. Featured investor names identify associated management firms, not personal portfolios.
