Tepper’s Appaloosa Exits Sandisk, Boosts TSMC and AI Bets

David Tepper’s Appaloosa LP is closely watched for contrarian trades that have earned the billionaire investor a reputation as a bottom-fisher. Its quarterly Form 13F offers a lagged snapshot of U.S.-listed long equity and options positions, making shifts toward semiconductors and AI infrastructure a useful signal of where the fund sees upside. The filing excludes cash, short positions and many overseas assets, and does not show trades made after quarter-end.

In a filing dated Aug. 14 covering holdings as of June 30, 2026, Appaloosa exited Sandisk and Corning stakes that were worth $178.7 million and $153.6 million, respectively, at the end of March, while also selling L3Harris and RTX. It raised its Taiwan Semiconductor Manufacturing Co. ADR position to 1.65 million shares, valued at $788 million, and initiated a 1,078,248-share CoreWeave stake worth $107 million. The fund also added Broadcom and lifted Baidu to about $148 million while trimming some Chinese e-commerce exposure.
