About & Data Sources
What this site is, where the data comes from, and how to read it.
What we do
GuruTrack aggregates two public U.S. financial-disclosure datasets into one structured, continuously-updated reference: hedge-fund and "guru" holdings from SEC Form 13F quarterly filings, and U.S. politicians' securities trades disclosed under the STOCK Act. We add structure — per-stock, per-person, per-theme views, quarter-over-quarter moves and rankings — on top of the raw filings.
Data sources
- Guru holdings: SEC EDGAR — Form 13F quarterly filings by institutional investment managers.
- Politician trades: official U.S. House and Senate financial-disclosure portals (STOCK Act filings).
- Prices: end-of-day market data, used only for context (e.g. change since quarter-end).
All holdings data derives from official public filings; we do not use private or paid position data.
Caveats & methodology
- 13F is a quarter-end snapshot, published up to ~45 days late; STOCK Act trades are disclosed up to ~45 days after the trade.
- 13F covers long U.S. equities (and certain options) only — no shorts, most bonds, foreign listings or cash.
- Politician trade amounts are ranges, not exact values; we display the disclosed range.
- Tickers and names are normalized from raw filings (CUSIP → ticker); historical or ambiguous mappings are resolved conservatively.
How to cite
You're welcome to quote and cite this data. Please attribute to "GuruTrack", link to the specific page, and keep the "data as of" quarter or date shown on the page — the underlying filings are delayed by design.
FAQ
What is a 13F filing?
A quarterly report that institutional investment managers with over $100M in U.S. equities must file with the SEC, disclosing their long U.S. stock positions as of quarter-end. It is published up to 45 days after the quarter ends.
What is a STOCK Act disclosure?
Under the STOCK Act, members of the U.S. Congress (and certain officials) must disclose their securities trades, generally within 30–45 days. Amounts are reported in ranges (e.g. $15k–$50k), not exact figures.
How fresh is the data?
13F holdings are quarter-end snapshots published up to ~45 days late; politician trades are disclosed up to ~45 days after the trade. GuruTrack refreshes shortly after new filings are published, but the underlying delay is set by law — no site has real-time data.
Why don't 13F filings show the full portfolio?
13F covers long U.S.-listed equities and certain options. It excludes short positions, most bonds, foreign-listed holdings and cash, so a guru's true exposure can differ materially from the filing.
Can I copy these portfolios as investment advice?
No. The data is delayed, partial, and historical — a position may already be sold by the time it is public. GuruTrack is a research and information tool, not investment advice.
