We track the 15 largest hedge funds and asset managers (Berkshire, Bridgewater, Renaissance, Citadel, Two Sigma, Millennium, Tiger Global, Point72, Viking, Lone Pine, Pershing Square, Appaloosa, DE Shaw, AQR, Baupost). Watching their position changes is one of the strongest signals retail investors have for institutional sentiment — but the data lags ~45 days because filings are quarterly.

About institutional activity
The Institutional page surfaces what large investors are doing, drawn from SEC filings: 13F quarterly institutional holdings, detection of crowded trades where many managers overlap, and clusters of insider buying or selling from Form 4 filings.
- What is a 13F filing?
- Form 13F is a quarterly report that institutional investment managers with over $100 million in US equities must file with the SEC, disclosing their long positions. It offers a lagged but detailed view of what large funds hold.
- What is a crowded trade?
- A crowded trade is a position held by an unusually large number of institutions at once. Crowding can amplify moves when sentiment shifts, so the page flags stocks with high 13F overlap as potentially crowded.
- What do insider transaction clusters indicate?
- When several corporate insiders buy or sell the same stock within a short window — reported via SEC Form 4 — it can be a meaningful signal. Clustered insider buying in particular has historically drawn investor attention.
