13F filings from legendary investors
13F Legendary Investor Tracker
The BRRR Legends Tracker monitors 13F SEC filings from legendary investors including Warren Buffett (Berkshire Hathaway), George Soros (Soros Fund Management), Stanley Druckenmiller (Duquesne Family Office), and other institutional giants. This comprehensive database tracks quarterly portfolio changes, new positions, exits, and position sizing adjustments from the most successful hedge fund managers and value investors.
What Are 13F Filings?
Form 13F is a quarterly SEC filing required from institutional investment managers with over $100 million in assets under management. These filings must disclose all equity positions worth more than $10,000, providing transparency into how the world's most successful investors allocate capital. Filed within 45 days of quarter end, 13F forms reveal long equity positions but exclude short positions, derivatives, foreign holdings, and fixed income securities.
Which Legends Are Tracked

How to Use This Data
Legendary investors often accumulate positions months before their investment thesis becomes apparent to the broader market. By tracking 13F changes — new positions, increased stakes, or complete exits — you can identify stocks receiving attention from proven capital allocators. However, remember the 45-day reporting lag means you're seeing historical positioning, not real-time trades.
Key Signals to Watch:
- • New Positions: Fresh capital allocation often signals conviction
- • Increased Stakes: Adding to winners or averaging down
- • Complete Exits: May indicate thesis breakdown or better opportunities
- • Concentration Changes: Position sizing reveals conviction levels
Sector Rotation Insights
The tracker analyzes portfolio concentration, sector rotation patterns, and timing of major position changes across technology, healthcare, financials, energy, and emerging sectors. When multiple legends simultaneously increase exposure to specific sectors — such as energy during 2021-2022 or technology during AI adoption phases — it often signals major thematic shifts before they become consensus trades.
Historical analysis shows these legends often anticipate major market moves months in advance through their portfolio positioning. Whether Buffett accumulating Japanese trading companies, Soros betting against currencies, or Druckenmiller rotating between growth and value cycles, 13F tracking provides valuable intelligence for both fundamental analysis and macro trend identification across various asset classes and market cycles.
