Methodology, data sources, and the fine print.
Track13F is a public database of Form 13F-HR filings submitted to the SEC by US institutional investment managers. Each filing discloses long equity positions held as of the last day of a calendar quarter.
Common questions about 13F data and how Track13F presents it.
A 13F is a quarterly SEC report that institutional investment managers with over $100M in qualifying assets must file 45 days after each quarter-end. It discloses long US equity positions — no shorts, no bonds, no private holdings.
We pull raw 13F-HR submissions from the SEC EDGAR full-text search and filings API, parse the information table, and normalize CUSIPs to tickers using an internal mapping table updated monthly.
Directory pages refresh hourly. The recent-filings feed refreshes every 5 minutes during heavy filing windows (roughly Feb 15 / May 15 / Aug 15 / Nov 15). Trending and aggregate pages refresh every 30 minutes.
Annualized and quarterly return estimates are computed from reported position values, adjusted for entries and exits. Returns are approximate — 13F data excludes cash, shorts, and non-equity exposure.
Funds with fewer than 1 filing, AUM under $100M, or insufficient cross-filer coverage are intentionally light to avoid misleading readers. These pages are marked noindex until more data is available.
No. Track13F is an informational research tool. 13F data lags by up to 45 days and does not capture a filer's complete economic exposure. Do not use this site as a sole basis for investment decisions.
