Key Points

  • Greg Abel has been appointed as Warren Buffett’s successor as the CEO of Berkshire Hathaway.

  • Bill Ackman, manager of Pershing Square Capital Management, has significantly reduced his stake in Alphabet.

  • In Q1 2026, Ackman sold 95% of Alphabet shares, while Berkshire increased its position by over $23 billion, accounting for 7% of its portfolio.

In a notable shift in investment strategy, Bill Ackman’s Pershing Square Capital Management sold 95% of its stake in Alphabet, transitioning funds toward Microsoft with an investment valued at approximately $2.1 billion. Ackman’s decision was not based on bearish sentiment towards Alphabet, as he maintains a long-term bullish outlook on the company amidst current lofty valuations.

In contrast, Berkshire Hathaway, under newly appointed CEO Greg Abel, tripled its Class A share position in Alphabet, now valued at over $23 billion, making it the fifth-largest holding in its portfolio. This marked a significant first move into AI-related stocks for Berkshire, reflecting different investment timelines and strategies between the two billionaires.
