Tracking the investment choices of billionaires can provide valuable insights for long-term investors. Funds with assets exceeding $100 million are mandated to disclose their holdings at the end of each quarter, with this information becoming public 45 days post-quarter. This regulatory requirement allows investors to gauge not only the performance of these funds but also the strategies utilized by successful investors.
Among the notable figures in this space is David Tepper, founder of Appaloosa Management, recognized for his successful long-term investment strategies. Unlike many short-term traders, Tepper’s approach focuses on enduring stock positions, making his activities particularly noteworthy. In the fourth quarter, Appaloosa acquired five new stocks, and with many of these stocks now trading below their fourth-quarter levels, Tepper’s insights may offer attractive buying opportunities for investors.
During the fourth quarter, Tepper notably increased his stakes in Alphabet (GOOG +3.77%, GOOGL +3.98%), Microsoft (MSFT +0.00%), and Meta Platforms (META +6.31%). Collectively, these companies are often referred to as the leading AI hyperscalers. Specifically, Tepper raised his holdings in Alphabet by 29%, in Meta by 62%, and in Microsoft by 8%. Following a mid-Q4 price surge for Alphabet, the stock has since retracted somewhat, while Meta has experienced a 20% decline since the start of Q4 2025, and Microsoft has dropped nearly 30%. This pricing dynamic potentially positions these stocks as significant bargains.
Investors are currently wary of the substantial expenditures these companies are committing to AI development. All three are channeling considerable cash flows into expanding their AI computing capabilities, anticipating that such investments are essential for future competitiveness. The market, however, is reacting negatively to these massive outlays given the uncertain returns associated with such ventures, leading to stock price dips across the board.
As Tepper’s investments suggest, the downturn in these stocks could represent an advantageous entry point for investors. Speculation is already building that when the next round of filings is released around May 15, Tepper may have further increased his positions in these three stocks, reaffirming his bullish outlook.
AI Infrastructure Investments
In addition to AI hyperscalers, Tepper has also invested in stocks related to AI infrastructure, crucial for the sustainability of the computing power required by such tech giants. Appaloosa’s purchases during Q4 included significant stakes in Micron Technology (MU +7.08%) and Taiwan Semiconductor Manufacturing (TSM +5.11%). Appaloosa increased its Micron holdings by a substantial 200%, while Taiwan Semiconductor saw a more modest increase of 7%, yet it remains a significant 5% of their portfolio.
The dual nature of these investments aligns with broader trends in AI development. Micron specializes in memory chips, whereas Taiwan Semiconductor focuses on logic chips, providing two complementary approaches to capitalizing on the growing demand for AI computing resources. Both companies are forecasting robust growth, with Taiwan Semiconductor projecting its AI chip revenue to rise at a compound annual growth rate of mid- to high-50% from 2024 to 2029. Micron anticipates its high-bandwidth memory market will expand dramatically, estimating growth from $35 billion in 2025 to $100 billion by 2028. These projections underscore the potential for substantial returns, making them appealing investment prospects for the coming years.
As the market continues to evolve, Tepper’s strategic moves provide a lens through which investors can consider the long-term viability of these tech giants and the infrastructure supporting them. While the current market sentiment may be cautious, the calculated investments made by seasoned investors like Tepper could pave the way for significant opportunities ahead.
