Recent 13-F filings show several hedge funds and large institutions reduced holdings in "Magnificent Seven" companies — including Nvidia (NVDA), Microsoft (MSFT), Amazon (AMZN), and Alphabet (GOOGL) — during the fourth quarter of 2025, mainly after a sharp AI-driven rally pushed valuations higher and raised questions about how quickly heavy AI spending will turn into profits. ### President's Day Sale - 70% Off - Unlock hedge fund-level data and powerful investing tools for smarter, sharper decisions - Stay ahead of the market with the latest news and analysis and maximize your portfolio's potential ## **Tiger Global Trims Key AI Positions** Tiger Global, a large U.S.-based hedge fund, reduced its Microsoft holding to 5.47 million shares from 6.5 million shares. Even after the cut, the stake is still worth about $2.6 billion and remains one of its largest positions. It also: - cut its Amazon stake by roughly 9% to about 10 million shares (around $2.3 billion) - trimmed its Nvidia position, now valued near $2.1 billion ## **Adage Capital Trims Big Tech, Increases Oracle Bet** Meanwhile, hedge fund Adage Capital made smaller reductions of roughly 1%–3% in its holdings of Microsoft, Alphabet, Amazon, and Nvidia. However, the fund increased investment elsewhere in the AI ecosystem. It boosted its stake in Oracle (ORCL) by about 19% to nearly 1.87 million shares, valued at roughly $365 million. Several large investors made similar adjustments. Warren Buffett's Berkshire Hathaway (BRK.B) continued to trim its stakes in Apple and sold a large portion of its Amazon stake. Meanwhile, the fund opened a new position in The New York Times Co.'s (NYT) stock in the fourth quarter of 2025 just before the shares rallied to an all-time high. Separately, SoftBank disclosed it had sold its Nvidia stake earlier to raise cash for further investment in OpenAI. ## **Which Magnificent 7 Stock Is the Better Buy?** Now, let's see how Wall Street analysts are weighing in on the above-mentioned names. Analysts think that Microsoft stock has the most room to run. In fact, Microsoft's average price target of $593.38 per share implies 49.5% upside potential. ### 相關股票 - [Berkshire Hathaway (BRK.A.US)](https://longbridge.com/zh-HK/quote/BRK.A.US.md) - [Apple (AAPL.US)](https://longbridge.com/zh-HK/quote/AAPL.US.md) -
