How 13F filing transparency works
Under federal law, large institutional investment managers must publicly disclose their equity holdings every quarter. Here's how the disclosure process works.
SEC Form 13F
Investment managers with $100M+ in qualifying assets must file Form 13F with the SEC within 45 days of each quarter end. The filing lists all Section 13(f) securities held, including shares, market value, and investment discretion.
We track changes
We parse every 13F filing from SEC EDGAR and compare holdings quarter-over-quarter to show exactly what changed — new positions, increased stakes, trims, and complete exits. We resolve CUSIPs to tickers for easy lookup.
Public data
All data is sourced from official SEC EDGAR filings. No data is estimated or inferred — only what's in the official 13F-HR documents. We handle amendments by replacing original filing data with the corrected version.
Frequently asked questions
Everything you need to know about 13F hedge fund filings and institutional portfolio tracking.
What is a 13F filing?
A 13F filing is a quarterly report required by the SEC from institutional investment managers with at least $100 million in qualifying assets under management. The filing discloses the manager's equity holdings, providing transparency into what large investors own.
How often are 13F filings updated?
13F filings are required quarterly, within 45 days of the end of each calendar quarter. For example, Q4 (ending December 31) filings are due by February 14. There is a lag between when trades occur and when they are disclosed.
What does a 13F filing include?
13F filings list all Section 13(f) securities — primarily US-listed equities, ETFs, and some convertible bonds. Each entry shows the issuer name, CUSIP, shares held, market value, and whether the position is a put, call, or shares. Options and foreign-listed stocks are not required to be reported.
How accurate is the data?
All data is sourced directly from SEC EDGAR filings. We parse the official XML InfoTable documents and resolve CUSIPs to tickers using the OpenFIGI API. Some older or amended filings may have formatting differences. We handle amendments by replacing the original filing data.
Why do portfolio values seem delayed?
13F filings reflect positions as of the last day of each quarter, not the filing date. A filing submitted in February 2026 shows holdings as of December 31, 2025. Funds may have already changed their positions by the time filings become public.
Can I see what a fund bought or sold?
Yes. We compare holdings quarter-over-quarter to compute changes. You can see new positions, increased positions, decreased positions, and completely exited positions for every fund. Visit any fund's Changes page to see the full breakdown.
