Institutional Holdings Report (Form 13F-HR) SEC Filing API

Form 13F-HR is the quarterly holdings report that institutional investment managers exercising investment discretion over $100 million or more in Section 13(f) securities must file with the SEC. The information table discloses every reportable U.S.-listed equity position held at quarter-end — issuer name, CUSIP, security class, market value, shares, voting authority, and any put/call options. 13F filings are the primary source for tracking hedge-fund and asset-manager positioning ('whale watching') and quarter-over-quarter portfolio changes. Because a 13F is filed under the investment manager's CIK rather than the issuer's, the richest way to query it is by manager or by stock: see the Institutional Holdings API for parsed, queryable 13F holdings with quarter-over-quarter analytics.
