Track 13F Holdings & Public Disclosures

Research & data notes

Turn public disclosures into verifiable research

Whale Analyzer separates institutional holdings, personal ownership filings and political financial disclosures. Use period comparisons, holding filters and original-source links to investigate a change. Each disclosure answers a different question; choose the record before interpreting the numbers.

Institutions: compare two matching periods

Check the reporting entity and report dates, then compare share counts for the same security class. A higher market value can reflect a higher price. A new record can involve an amendment or identifier change; it does not establish cash spent buying.

Read the 13F verification guide

Personal disclosures: preserve dates and limits

Political transaction ranges are not exact execution amounts. SEC ownership records are not complete portfolios. Read transaction, filing and position dates separately; adding different disclosures together does not establish total wealth.

Browse records by disclosure type

Stocks: understand the tracked sample

Shared holdings cover the reporting entities tracked here. Sample concentration is not market-wide institutional ownership, and modeled costs are not a fund’s actual purchase prices. Check each record’s period, source and missing fields before drawing a conclusion.
