Bill Ackman, the founder of Pershing Square Capital Management, has increased his fund's holdings in Microsoft while reducing its position in Alphabet [1], [2].

This shift in strategy by one of the world's most prominent activist investors signals a change in sentiment regarding the valuation of the two biggest players in the AI race. By rotating capital from Google's parent company into Microsoft, Ackman is betting on a recovery for the software giant.

According to reports, Pershing Square has been loading up on Microsoft stock [1], [2]. This move comes as the fund simultaneously trims its stake in Alphabet [1], [2]. The decision to increase the Microsoft position was driven by a recent sell-off in the stock's price.

Ackman said Microsoft is compelling on the numbers following that decline [1], [2]. The valuation of the company now presents an attractive entry point for the fund, which typically seeks high-conviction investments in large-cap companies.

The rotation between these two tech titans suggests a tactical move based on short-term price action rather than a fundamental dismissal of Alphabet's long-term prospects. However, the ability of Microsoft to maintain its lead in enterprise AI and cloud computing remains a central pillar of the investment thesis.

Pershing Square continues to manage its portfolio with a focus on companies that exhibit strong fundamentals, and clear paths to growth [1], [2]. The current reallocation reflects the fund's approach to buying assets when they are perceived to be undervalued by the broader market.

This portfolio rotation indicates a tactical shift toward value-hunting within the mega-cap tech sector. By exiting a portion of Alphabet to buy Microsoft during a dip, Ackman is leveraging a volatility window to lower his cost basis in a company he believes is fundamentally undervalued despite recent market pressure.
