David Tepper's Appaloosa Ups Micron Stake By 250%, Trims Nvidia And Amazon

Billionaire David Tepper, founder of Appaloosa Management, aggressively took profits on Chinese tech and some Mag 7 mainstays while doubling down on a recovery play in the semiconductor sector.

  • MU stock is moving.  

The Big Bet on Micron

Tepper's Appaloosa turned red-hot for Micron Technology, Inc. (NASDAQ:MU). The filing reveals a staggering 250% increase in Micron shares, with Appaloosa adding exactly 1,000,000 shares during the quarter. 

The fund's total position in Micron is now 1.5 million shares, valued at over $428 million.

Tepper appears to be moving “down the stack,” seeking value in the hardware components that power AI rather than the chip designers themselves.

Trimming the Tech Titans

Another striking move in the filing was the significant reduction in Alibaba Group Holding Ltd. (NYSE:BABA). Appaloosa slashed its stake by over 1.3 million shares, a 20.3% reduction. 

Despite the cut, Alibaba remains the fund's largest individual holding, representing 10.88% of the total portfolio—down from a dominant 15.61% in the previous quarter.

Tepper also hit "sell" on other tech heavyweights:

  • Amazon (NASDAQ:AMZN): Reduced by 12.8%, or roughly 320,000 shares.
  • Nvidia (NASDAQ:NVDA): Trimmed by 10.5%, liquidating 200,000 shares.

Tactical Shifts 

Tepper showed renewed interest in Meta Platforms (NASDAQ:META), boosting the stake by over 62%, and continued his steady accumulation of Taiwan Semiconductor Manufacturing Co. (NYSE:TSM) and Alphabet, Inc. NASDAQ:GOOG) as well.

Jensen Huang's sudden resignation shrouded in suspicion: Did the White House secretly intervene? Is a return possible in the future?

Only a few days separated Jensen Huang’s strong support from the board last Sunday and his late-night resignation on Wednesday. Multiple reports of the Wednesday night Nvidia board meeting were co-authored by Washington-based journalists—who do not typically cover Nvidia—fueling rumors of "White House pressure and information leaks." Huang’s unique value lies in leveraging his personal reputation to secure the supply chain and drive the implementation of technological roadmaps, making him difficult to replace. Some analysts note that, drawing on examples such as Steve Jobs’ return to Apple, it is possible that Huang may come back in the future.
