What We Do

FilingFrog makes institutional investment disclosures searchable, comparable, and useful. Every quarter, asset managers with over $100 million in U.S. equities file Form 13F with the SEC; registered mutual funds and ETFs file Form NPORT-P; activist investors file Schedule 13D when they cross a 5% stake. All of this is public data, but it has historically lived in raw XML on EDGAR and been difficult to work with.

We ingest these filings, reconcile them against a canonical security master, and surface them through search, screeners, and side-by-side comparison tools — so investors, analysts, and researchers can see what the world's largest managers actually own, without a Bloomberg terminal.

Data & Accuracy

All data on FilingFrog comes from the SEC's EDGAR database. We process raw XML filings, reconcile them against a canonical security master, and publish the results through the site.

A few things to keep in mind when working with this data:

  • 13F filings are disclosed up to 45 days after quarter-end.
  • NPORT-P filings are disclosed up to 60 days after the reporting period.
  • Positions may have changed materially between the reporting date and the publication date.
  • Some positions may be confidentially treated and withheld from disclosure.
  • FilingFrog is an information platform, not an investment adviser. Nothing on the site is investment advice.

For official filings, refer to the primary sources at sec.gov/edgar.
