Frequently Asked Questions
How often is the data updated?
13F filing data is updated quarterly — the SEC requires filing within 45 days of each quarter end. Insider trades and congressional disclosures update more frequently as new filings come in.
Is HedgeTrack data free?
Yes. All 13F holdings, insider trade, and congressional disclosure data is free to browse. We're building a Pro tier for API access and advanced screening.
Can I trust 13F data for investment decisions?
13F data reflects positions as of the quarter end, not real-time. Funds can have exited positions by the time the filing is public. Use it as one signal among many — not as current state.
What is a "convergence signal"?
A convergence signal is when multiple independent data sources (e.g., 13F buying + insider purchases + congressional buys) all point in the same direction for the same stock. Multi-source agreement tends to be more meaningful than any single source alone.
How is HedgeTrack different from Unusual Whales or WhaleWisdom?
