Whalex: US Stock Tracker

What are the world’s smartest investors—and most powerful politicians—buying right now?

Warren Buffett, Ray Dalio... every position they add, trim, or exit is a signal worth watching. Whalex parses official disclosures directly and translates them into clear, readable portfolio moves for 100+ of the world's top institutional investors, corporate insiders, and US Congress members.

What you can do with Whalex:

Follow the Managers You Trust
Choose the funds you want to track—Berkshire Hathaway, Bridgewater, Renaissance Technologies, Tiger Global, and many more. Every quarter, when their 13F filings drop, their latest moves appear in your personal feed.

Track Congressional Trades (STOCK Act Tracker)
See what US Senators and Representatives are buying and selling. Under the STOCK Act, politicians must disclose their personal stock transactions. Monitor high-profile portfolios from Nancy Pelosi, Tommy Tuberville, Josh Gottheimer, and more. Filter by political party, transaction size, and specific politicians to see where government insiders are putting their money.

Real-Time Insider & 13D/G Signals
Don't wait 45 days for quarterly updates. Track corporate insider transactions (Form 4) and major shareholder disclosures (13D/G) in real-time. See exactly when CEOs, CFOs, or 10% owners buy or sell their own company’s stock. Filter signals by trade value, transaction type, or specific insider roles to catch high-conviction moves as they happen.

Holding History Charts
See the full story, not just the latest snapshot. Whalex's interactive charts show how any institution held a stock across the complete holding history—toggle between portfolio weight, market value, and share count. Color-coded action markers (NEW / ADD / REDUCE / EXIT) make it instantly clear whether a fund is building a position or quietly exiting.

Whale Consensus Portfolio
What if you treated all 100+ top funds as one single "super fund"? See which stocks are most widely held across elite institutions, which sectors smart money is concentrating in, and how the aggregate positioning compares to the S&P 500.

Portfolio Overlap
Compare any two institutions side by side to find the stocks they both back—and where they diverge.
