Pershing Square's first-quarter 13F filing, which details U.S.-listed equity holdings as of March 31, 2026, reveals that Bill Ackman aggressively added shares of Amazon and Microsoft. The filing shows that Ackman purchased Amazon hand over fist, turning a previously smaller position into a top holding. Similarly, his stake in Microsoft was substantially increased, reflecting a strong conviction bet on the two cloud and enterprise software giants. Conversely, Ackman slashed Pershing Square's exposure to Alphabet, one of the fund's largest positions in prior quarters, by a staggering 95%. The exact number of shares sold was not disclosed, but the reduction indicates a sharp pivot away from the search and advertising conglomerate. The sale occurred during a period when Alphabet's stock continued to trade near its highs, suggesting Ackman may have taken profits or reallocated capital to other AI-related opportunities. The 13F filing, submitted to the Securities and Exchange Commission, offers a quarterly snapshot of holdings for large institutional managers. While it does not reflect the timing of trades within the quarter, it provides a clear directional signal of Ackman's shifting focus among the dominant players in artificial intelligence and cloud computing.

Expert Insights

performance outlook Sector rotation analysis is a valuable tool for capturing market cycles. By observing which sectors outperform during specific macro conditions, professionals can strategically allocate capital to capitalize on emerging trends while mitigating potential losses in underperforming areas. From a professional perspective, Bill Ackman's first-quarter repositioning underscores the ongoing rotation within the technology sector as artificial intelligence reshapes competitive dynamics. By increasing stakes in Amazon and Microsoft, Ackman is aligning his fund with companies that have deep integration of AI across their core businesses — from AWS's AI tools to Microsoft's Copilot ecosystem. The near-total exit from Alphabet, however, could signal that Ackman sees more limited upside or higher competitive risk for the search giant relative to its peers. Such high-profile portfolio moves by a billionaire investor often attract attention from retail and institutional investors alike. However, it is important to note that 13F filings are backward-looking and do not reveal the reasoning behind specific trades. Ackman's decision may also reflect portfolio risk management or tax considerations rather than a fundamental bearish view on Alphabet alone. Investors considering similar reallocations should evaluate their own risk tolerance and investment horizons. While Ackman's track record is notable, past performance does not guarantee future results, and concentrated bets can introduce significant volatility.
