David Tepper Exits Key Stocks, Narrows AI Bets

Billionaire investor David Tepper's Appaloosa Management has significantly reshaped its holdings, closing out 12 positions entirely as of the second quarter of 2026, according to a 13F filing on August 14, 2026. The pattern emerging from these exits indicates a strategic move to consolidate sprawling thematic investments into more focused, high-conviction single-name bets. This adjustment comes as global markets navigate varying economic landscapes, with major indices showing modest movements: the S&P 500 down 0.29%, the Dow Jones off 0.31%, and the Nasdaq 100 declining 0.22%.

Among the most notable exits are SanDisk (NASDAQ: SNDK) and Corning (NYSE: GLW), both experiencing significant price drops since Tepper's positions were closed on June 30, 2026, with SanDisk down 28% and Corning down 35%. Tepper also divested from defense contractors RTX and L3Harris Technologies, as well as two Chinese internet stocks, PDD Holdings and JD.com, alongside the KraneShares CSI China Internet ETF (NYSEARCA: KWEB).

However, Tepper's strategy reveals continued conviction in specific areas. He maintained a substantial holding in Micron (NASDAQ: MU), despite trimming his stake by approximately 13% of shares, and increased his position in Baidu. This suggests a preference for direct AI exposure and specific growth narratives over broader sector baskets.
