Overview
- Appaloosa’s second‑quarter 13F shows the fund fully exited its 281,250‑share SanDisk holding and trimmed Micron while keeping a large Micron stake.
- Proceeds were redeployed into concentrated AI bets, with Amazon rising to about 5 million shares and new or larger positions in Nvidia, TSMC, Broadcom and CoreWeave.
- The filing also discloses smaller new stakes including SpaceX and added exposure to power generators Vistra and NRG to back growing electricity needs for large data centers.
- Appaloosa reported a 32% return in the first half of 2026 that the filing attributes in part to earlier memory gains, which helps explain why Tepper locked profits after SanDisk’s large rally.
- These holdings come from a quarter‑end 13F snapshot that does not show trades after June 30 or any derivatives and therefore may not reflect the fund’s current positions.
