The global memory shortage combined with the AI computing power frenzy has created a stark contrast between his chip bets and the plummeting software stocks David Tepper of Appaloosa Management made a significant bet on artificial intelligence-related investments in the fourth quarter of last year, substantially increasing his position in Micron Technology and establishing a new position in Korean stocks, both of which have performed strongly this year. The billionaire hedge fund manager raised his stake in Micron Technology to $428 million, a 200% increase, making the key memory chip manufacturer for AI systems the fund's fourth-largest holding, according to InsiderScore data. **The global memory shortage has driven Micron's stock price up nearly 30% this year.** **** Meanwhile, Tepper established a new position worth $182.3 million in the iShares MSCI Korea ETF (EWY). This ETF primarily holds chip giants like Samsung Electronics and SK Hynix, which have surged 34% this year and recently hit a new high, attracting investors seeking overseas beneficiaries of AI. **The strong performance of these chip-related investments stands in stark contrast to other sectors of the market. Software stocks have significantly declined this year, as investors worry that the latest AI models will impact the industry's reliance on high-fee business models.** **** ## Increasing Bets on Memory Chips Tepper's investment in Micron Technology demonstrates strong confidence in AI infrastructure. In addition to raising his stock position to $428 million, he also purchased $71.4 million in nominal value of Micron call options. However, it is currently unclear whether he has sold these contracts or when they expire. The global memory shortage has been a key factor driving Micron's stock price surge. As a major producer of computer memory required for AI systems, Micron directly benefits from the surge in demand brought about by the AI boom. ## Targeting Korean Chip Leaders Tepper's investment in the Korean ETF provides him with exposure to Samsung Electronics and SK Hynix, which dominate the ETF's holdings. Investors are looking overseas for beneficiaries of the AI supply chain, leading to increased interest in Korean chip manufacturers. The 34% increase in this ETF this year reflects the market's recognition of the role of Asian chip manufacturers in the AI wave. This performance contrasts with the weakness of U.S. tech stocks. ## Other Major Holding Adjustments Alibaba remains Appaloosa's top holding, although Tepper reduced his stake by 20% in the fourth quarter. The Chinese internet giant has risen 6% this year. Alphabet is the fund's second-largest holding, with Tepper increasing his stake by about 29%. However, Alphabet has underperformed this year, weighed down by overall pressure on the tech sector These portfolio adjustments indicate that Tepper is reallocating assets from traditional tech stocks to chip manufacturers that directly benefit from AI infrastructure development ### Related Stocks - [MU.US - Micron Tech](https://longbridge.com/en/quote/MU.US.md) - [FTXL.US - First Trust Nasdaq Food & Semicon](https://longbridge.com/en/quote/FTXL.US.md) - [SOXL.US - Direxion Semicon Bull 3X](https://longbridge.com/en/quote/SOXL.US.md) - [SMH.US - VanEck Semiconductor ETF](https://longbridge.com/en/quote/SMH.US.md) - [MULL.US - GraniteShares 2x Long MU Daily ETF](https://longbridge.com/en/quote/MULL.US.md) - [EWY.US - ISHRS MSCI S Korea Capped](https://longbridge.com/en/quote/EWY.US.md) - [SOXX.US - iShares Semiconductor ETF](https://longbridge.com/en/quote/SOXX.US.md) - [SOXQ.US - Invesco PHLX Semiconductor ETF](https://longbridge.com/en/quote/SOXQ.US.md) - [MUU.US - Direxion Daily MU Bull 2X Shares](https://longbridge.com/en/quote/MUU.US.md) - [XSD.US - SPDR S&P Semicon](https://longbridge.com/en/quote/XSD.US.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 闪迪启动 30.8 亿美元二级市场股票发行 | 闪迪于 2 月 17 日宣布启动 30.8 亿美元的二级市场股票发行，涉及现有股东出售股份。西部数据将通过股权方式处置对闪迪的债权，具体债务规模和交易细节尚未披露。投资需谨慎，本文不构成个人投资建议。 | [Link](https://longbridge.com/en/news/276180619.md) | | Hodges Capital Management Inc. 出售了美光科技公司（Micron Technology, Inc.）的股票（$MU） | 霍奇斯资本管理公司在第三季度将其在美光科技公司（NASDAQ:MU）的持股减少了 3.8%，目前持有 106,063 股，价值约为 1770 万美元。包括挪威银行和先锋集团在内的其他机构投资者也调整了在美光的持仓。内部交易活动方面，执行副总 | [Link](https://longbridge.com/en/news/276209006.md) | | Meta 加码英伟达：未来数年部署数百万颗芯片，首次采用 Grace CPU | 根据周二发布的声明，Meta 承诺将使用更多来自英伟达的 AI 处理器和网络设备。同时，Meta 还将首次在其独立计算机的核心部件采用英伟达的 Grace CPU。此次部署将涵盖基于英伟达当前 Blackwell 架构，以及即将推出的 Ve | [Link](https://longbridge.com/en/news/276177748.md) | | Zweig DiMenna Associates LLC 出售了 30,098 股美光科技（Micron Tech）的股票，股票代码为 $MU | Zweig DiMenna Associates LLC 已将其在美光科技（Micron Technology, Inc.，NASDAQ: MU）的持股比例减少了 53.3%，在第三季度出售了 30,098 股，剩余 26,402 股，价值 | [Link](https://longbridge.com/en/news/276125703.md) | | Arvest 银行信托部门减少了其在美光科技公司$MU 的股票持仓 | Arvest Bank Trust Division 在第三季度将其在美光科技（NASDAQ: MU）的持股减少了 43.2%，目前持有 104,438 股，价值 1750 万美元。其他对冲基金也调整了他们的持仓，机构投资者持有该股票的 8 | [Link](https://longbridge.com/en/news/276104225.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
