David Tepper’s Appaloosa Slashes Portfolio by $1B — Amazon (AMZN) and Uber Emerge as Top Picks

Amazon.com, Inc., AMZN

Ride-sharing platform Uber experienced equally dramatic attention from Tepper. The hedge fund accumulated 4.5 million additional shares, effectively more than tripling its existing stake. Uber‘s position now commands a valuation of $455 million, placing it firmly among Appaloosa’s five largest investments.

Technology Sector Realignment and Fresh Opportunities

While some tech names enjoyed increased allocations, others faced significant reductions. Chinese e-commerce powerhouse Alibaba experienced the steepest decline, with Appaloosa cutting its stake from 5.1 billion shares to a mere 3.5 million — representing approximately $318 million in value reduction. Microsoft similarly faced the chopping block, as Tepper offloaded 410,000 shares, maintaining only 90,000 shares valued at roughly $33 million.

Despite these cuts, Appaloosa deployed capital into emerging technology opportunities. The fund established a completely new position in flash memory specialist Sandisk, purchasing 281,250 shares with an approximate value of $179 million. Additional investments flowed into Micron Technology and Taiwan Semiconductor Manufacturing Company, both of which saw expanded allocations.

Alphabet maintains its position as a core holding, comprising roughly 8% of the portfolio. Micron commands a 9% allocation, while Taiwan Semiconductor represents 8% of total assets.

Complete Aviation Sector Withdrawal

In a decisive move signaling concerns about the airline industry, Appaloosa liquidated every one of its aviation holdings during the first quarter. Positions in American, Delta, and United Airlines were sold entirely. The American Airlines stake alone consisted of 14.1 million shares with an estimated value of $217 million as of year-end 2025.

These divestments occurred amid escalating jet fuel expenses that compressed airline profit margins, challenges linked to geopolitical tensions including the Iran conflict.

As recently as the fourth quarter of 2025, American Airlines represented Appaloosas largest aviation sector bet. Three months later, by March 31, 2026, the fund maintained zero exposure to airline equities.

This strategic pivot demonstrates a deliberate transition away from travel-dependent industries toward technology infrastructure and consumer-facing digital platforms.

Teppers first-quarter adjustments reveal a philosophy of concentration over diversification, with fewer total positions but substantially larger commitments to Amazon, Micron, Uber, and Taiwan Semiconductor.

The 13-F regulatory filing reflects Appaloosas equity holdings as of March 31, 2026, and was submitted to the SEC in accordance with standard disclosure requirements.
