Billionaire David Tepper’s Strategic Moves in AI Stocks Revealed in 13F Filing

David Tepper's Appaloosa Management made waves in the second quarter with a dramatic 6X increase in its Nvidia stake, signaling strong conviction in the AI hardware leader. The fund simultaneously exited its position in an unnamed trillion-dollar AI stock, a bold contrarian move that highlights Tepper's active portfolio management style.

13F filings provide rare transparency into institutional trading activity, with the August 14 disclosure offering particular insights given recent market volatility. While Warren Buffett remains the most watched investor, Tepper's AI-focused plays increasingly command Wall Street's attention for their aggressive positioning in transformative technologies.

The reshuffling comes during a turbulent period for tech stocks, suggesting Appaloosa sees Nvidia's AI dominance as more durable than competitors'. Such high-conviction moves by billion-dollar funds often presage broader institutional trends in the market.
