In the fourth quarter, prominent hedge fund manager David Tepper has made significant moves in the investment landscape, particularly in the technology sector with a focus on artificial intelligence. Tepper has notably increased his investment in Micron Technology, raising his stake to an impressive $428.1 million. This hefty investment marks a 200% increase, making Micron the fund’s fourth-largest holding. The company, which plays a pivotal role in supplying computer memory essential for AI systems, has seen its stock rise by 40% this year due to a global shortage in memory supplies.
In a strategic maneuver, Tepper has also acquired call options on Micron with a combined notional value of $71.4 million. However, details surrounding the future of these contracts remain unclear, including whether he has sold them or the expiration dates of such options.
Expanding his portfolio further, Tepper has initiated a new position worth $182.3 million in the iShares MSCI South Korea ETF (EWY). This move aligns with a broader investor trend seeking exposure to international stocks that stand to benefit from the AI boom. The ETF has soared by 34% this year, achieving recent peaks primarily buoyed by major South Korean chip manufacturers Samsung Electronics and SK Hynix, both of which are thriving in an environment where traditional tech sectors are facing considerable challenges.
While the AI-driven sectors appear to be outperforming, other areas of the market have struggled. Software stocks, for instance, have taken a hit amid concerns that new AI models could disrupt their business models, which often rely on high fees. Additionally, wealth management and real estate stocks have also faced downward pressure in recent weeks.
Aside from his investments in Micron and South Korean equities, Tepper continues to maintain a diversified portfolio. His largest holding remains Alibaba, despite trimming his stake by 20% in the fourth quarter. Alibaba has experienced a modest increase of 6% this year. Tepper’s second-largest investment is in Alphabet, where he increased his exposure by approximately 29%. However, shares of Alphabet have lagged behind, reflecting broader volatility in the tech sector.
These strategic bets by Appaloosa Management highlight Tepper’s focus on navigating and capitalizing on the evolving dynamics of the technology and investment landscapes, particularly in sectors tied closely to the growth of artificial intelligence.
