Steve Mandel's Lone Pine Capital disclosed portfolio repositioning totaling $3.4B in gross turnover during Q1 2025, according to the firm's 13F filing submitted to the SEC on May 15. The Tiger Management alumnus exited $2.1B in combined positions across Microsoft, Amazon, and Meta—three names that represented 11.2% of the fund's $18.7B equity book at year-end 2024. The filing shows the fund now holds 87 long equity positions, down from 104 the prior quarter.
The exits were not panic selling. Lone Pine liquidated its 1.87M Microsoft shares between January and March, a position valued at $782M at December 31. The Amazon stake—891,000 shares worth $694M—disappeared entirely. Meta's 1.12M shares, valued at $627M, were also zeroed. In their place: new stakes in Applied Materials ($447M), Uber ($389M), and a 340% increase in the firm's Nvidia position to $1.21B, now the portfolio's third-largest holding. The Nvidia add came at an average cost basis near $118 per share, based on quarter-end marks and disclosed share counts.
The realignment signals two things. First, Mandel is rotating out of advertising-driven consumer platforms and cloud infrastructure into semiconductor capital equipment and mobility—sectors where margin expansion is tied to physical capacity, not user engagement. Second, the firm is concentrating. The top ten holdings now represent 64% of the portfolio, up from 58% in Q4. That kind of narrowing happens when a manager expects volatility to separate durable compounders from multiple compression. Lone Pine's historical playbook runs this way: reduce names, raise position size, hold through drawdowns. The 13F also shows the fund cut its healthcare exposure by $620M, exiting Eli Lilly and Merck entirely while maintaining UnitedHealth as a $890M anchor.
The timing matters. Mandel made these moves while the Nasdaq traded between 18,200 and 19,400 in Q1—a range that has since broken higher. If the Nvidia add was prescient, the Microsoft exit was early. The stock has rallied 14% since March 31. But Lone Pine does not trade for quarters. The fund returned 23.7% annualized from 2010 to 2023, according to investor letters reviewed by Bloomberg. That durability comes from avoiding heroism. The 13F shows no leverage artifacts, no derivatives, no preferred structures. Just 87 common equity positions held in size.
Allocators should watch Lone Pine's Q2 filing in mid-August to confirm whether the Nvidia position stays above $1B or gets trimmed after the stock's 38% gain since quarter-end. If Mandel adds to Applied Materials above $200 per share—it closed Q1 at $184—that confirms conviction in wafer fab equipment as the choke point for AI infrastructure, not the models themselves. Also worth tracking: whether the fund re-enters Microsoft below $400. Lone Pine has exited and re-entered core positions before. In 2019, the firm sold its entire Amazon stake, then rebuilt it six months later at lower prices. The pattern repeats when Mandel sees reflexivity breaking.
The 13F is three months stale, but the architecture endures. When a $18.7B fund with a 30-year track record moves 18% of its book in a quarter, the question is not what Mandel sold. It is what he saw that required selling it.
The takeaway
Lone Pine's Q1 realignment—$2.1B exited from mega-cap tech, $1.2B into Nvidia—signals rotation from platform engagement to semiconductor choke points.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
