Bill Ackman builds Microsoft position

PARAGRAPH 1 --- What happened: Bill Ackman's Pershing Square Capital Management recently exited its Alphabet position, selling all shares, and built a significant 5.65 million-share stake in Microsoft, disclosed in its Q1 13F filing. Ackman revealed on May 15 that he started buying Microsoft in February, describing the tech giant's valuation as "highly compelling." Notably, the Bill & Melinda Gates Foundation Trust also sold its entire Microsoft position during Q1.

PARAGRAPH 2 --- Market impact: Ackman's moves have implications for both tech giants and the broader market. Microsoft's underperformance this year relative to Alphabet and other cloud rivals has drawn Ackman's attention, suggesting he sees Microsoft as undervalued. His investment could boost Microsoft's stock price, benefiting other long shareholders. Meanwhile, Alphabet's rally may face headwinds as Ackman's absence from its shareholder base is notable, given his past influence.

PARAGRAPH 3 --- What to watch next: Microsoft's Q4 earnings, scheduled for June 27, will provide insight into Ackman's investment thesis, as the company is expected to report on its cloud and AI growth. Additionally, any further movements in Ackman's portfolio, as indicated by future 13F filings, will signal whether he maintains or adds to his Microsoft position, or shifts focus to other stocks. Lastly, the broader tech sector's performance in relation to the market will determine if Ackman's investment thesis plays out.
