Institutional ownership, decoded
FBInvestor turns raw SEC Form 13F filings into clean, searchable institutional ownership research.
What we do
Every quarter, institutional investment managers with over $100M in U.S. equities must disclose their holdings to the SEC on Form 13F. FBInvestor ingests these filings, normalizes them, and computes quarter-over-quarter changes so you can see exactly what the largest funds are buying and selling — by fund and by stock.
Data & methodology
- • Source: official SEC Form 13F structured data sets.
- • Coverage: the most recent four reporting quarters of 13F-HR holdings.
- • Securities are identified by CUSIP; issuer names are normalized to the most common reported label.
- • When a manager files an amendment, the latest filing for that quarter is used to avoid double-counting.
- • Position changes compare each manager's holding to the prior quarter they filed for.
Disclaimer
13F filings are reported with a delay of up to 45 days after quarter-end and reflect long U.S. equity positions only — they do not show short positions, cash, or non-U.S. holdings. FBInvestor is provided for informational and research purposes only and is not investment advice. Always do your own research.
