Appaloosa Management’s Micron bet surged over 100% after a Q4 2025 purchase amid AI-driven DRAM demand.
David Tepper’s Appaloosa Management secured a more than 100% gain on its Micron (MU) stake following a Q4 2025 investment. The hedge fund’s timing aligned with a rally in DRAM stocks driven by artificial intelligence demand.
Appaloosa’s 13-F filings for Q4 2025 did not disclose the exact purchase date but confirmed a sizable position in Micron. The fund also holds significant stakes in Amazon (AMZN) and Uber (UBER), targeting AI infrastructure and autonomous vehicle trends.
The move underscores Tepper’s track record in identifying high-growth AI plays, outperforming peers in early-stage market shifts.
