WhaleSignals turns publicly available data into clear, visual signals from the world's most-followed institutional investors.

TRACK 59 LEGENDARY FUNDS
Berkshire Hathaway, Bridgewater, Pershing Square, Appaloosa, Baupost, Coatue, Tiger Global and more — every quarter, straight from publicly available quarterly disclosures.

FIVE INDEPENDENT SIGNALS, NEVER BLENDED
- Holding Concentration Heatmap: see which stocks the most tracked funds hold right now, and who holds them.
- Conviction Scores: position size reveals how much a manager really believes. Browse each fund's top bets, or find stocks held with 5%+ conviction.
- Funds x Insiders: stocks institutions bought last quarter AND company insiders are buying on the open market right now (Form 4, purchase code P only).
- Divergence Detector: same quarter, opposite moves. Know when legendary investors disagree before you follow one of them.
