Frequently Asked Questions (FAQ)

What is SEC Form 13F (13F-HR)?

Under Section 13(f) of the U.S. Securities Exchange Act, every institutional investment manager (including hedge funds, mutual fund families, pension funds, and family offices) that exercises investment discretion over USD 100 Million or more in Section 13(f) US exchange-traded equities and options must file Form 13F-HR with the SEC within 45 days after the end of each calendar quarter.

Does this scraper calculate exact USD values and portfolio weights?

Yes. In accordance with current SEC EDGAR Form 13F XML specifications, all market values are reported in exact USD dollars (marketValueUsd), and this Actor automatically sums the entire 13F XML table to compute each individual holding's exact percentage weight (portfolioWeightPct) inside the fund's portfolio before sorting from largest position to smallest.

How can I connect this SEC 13F Whale API to Python, Google Sheets, or n8n?

You can trigger this Actor via the Apify REST API, the apify-client Python or Node.js SDK, or the native Apify integration node inside n8n, Make, Clay, and Zapier to export clean hedge fund portfolio tables automatically.
