1. Billionaire investor David Tepper made significant moves in the tech sector in Q3 2025. He initiated a new position in AI chipmaker AMD and increased his hedge fund’s stake in Chinese tech giant Baidu. Tepper also bought more shares of Qualcomm, preparing to compete with AMD and Nvidia.
  2. Tepper’s Appaloosa fund holds a relatively small portfolio of 45 holdings, focusing on AI stocks. Tepper’s move to increase AI exposure by investing in three AI stocks in Q3 shows strategic positioning in the tech sector.
  3. Tepper’s investment in AMD has paid off with a nearly 70% increase in share price since Q3. The company’s partnerships and growth strategy have contributed to its success. Baidu, often called the "Google of China," has also seen a stock jump of over 30% post Q3.
  4. Tepper’s decision to buy more shares of Baidu and Qualcomm aligns with their growth potential. Qualcomm’s expansion into data center and robotics markets could be lucrative in the long run, despite a modest stock increase post-Q3.
  5. Tepper’s best AI move in Q3 was initiating a significant new stake in AMD. While AMD may not surpass Nvidia, its potential to gain market share with hyperscalers and other customers deploying AI models makes it a strong investment choice.
