}Datasets
Ownership Dataset
Positions that US institutional investment managers report on SEC Form 13F at a quarter end: who holds a company’s securities, or what a manager holds. Each position is a manager’s shares (or principal amount) and market value in one security, summed over its 13F lines, with the filings it was read from in sources.
Filter by the security (companyIds, companyTickers or cusips), by the manager (holderCompanyIds or holderCiks), or both. Without periodEnd, positions are for the latest quarter end whose 13F filing deadline (45 days) has passed. Positions are current values; with asOf, they are what had been published by that time (a filing counts from the end of its filing date in New York). Results are largest market value first; page through them with pageToken. If the holdings change while you page (a new or corrected filing is published), the next page returns 409: start again without pageToken, so you never mix two versions of the data.
Option positions (puts and calls) are left out unless include=options; their underlying shares never add to shares. 13F reports long positions only, with no shares outstanding, so positions carry no percentage of a company.
