SEC 13F Tracker -- Institutional Holdings API

Track SEC Form 13F filings to monitor institutional investment holdings. This actor queries the SEC EDGAR system to retrieve 13F-HR filings from hedge funds, mutual funds, pension funds, and other institutional investment managers who manage $100 million or more in qualifying securities. Search by CIK number for a specific filer or by company name to discover institutional investors.

Form 13F is a quarterly report required by the SEC that discloses the equity holdings of institutional investment managers. These filings provide transparency into what stocks, ETFs, and other securities large institutions are buying, selling, or holding. This actor extracts filing metadata including the filer name, CIK, filing date, period of report, form type, accession number, and a direct link to the EDGAR filing page.

FAQ

What data source does this actor use? The actor queries the SEC EDGAR system directly. When a CIK is provided, it fetches the submissions JSON from data.sec.gov. For name-based searches, it uses the EDGAR full-text search index (efts.sec.gov). Both are official SEC data sources.

What is a CIK number? CIK (Central Index Key) is a unique identifier assigned by the SEC to each entity that files with the commission. You can look up a company's CIK at sec.gov/cgi-bin/browse-edgar.

What is the difference between 13F-HR and 13F-HR/A? 13F-HR is the original quarterly holdings report. 13F-HR/A is an amendment to a previously filed 13F-HR, typically filed to correct errors or add missing positions.

How often are 13F filings submitted? Institutional investment managers must file Form 13F within 45 days of the end of each calendar quarter (March 31, June 30, September 30, December 31).

Does this return individual stock positions? This actor returns filing-level metadata (dates, filer name, accession numbers). To retrieve individual position-level data from within a 13F filing, you would need to parse the XML information table referenced by the accession number.

Integration Notes

Results are stored in the Apify dataset and can be exported as JSON, CSV, XML, or Excel. Schedule quarterly runs timed to the 13F filing deadlines (approximately 45 days after quarter-end) to capture new filings as they appear. Use the accession number from results to fetch the detailed holdings XML from EDGAR for position-level analysis. The Apify API and webhooks enable integration into investment dashboards, research platforms, and alerting systems.

Built with Apify SDK.
