Billionaire Bill Ackman Sold This Stock While Warren Buffett Successor Greg Abel Bought It. Who's Right?
2026-05-25 10:20:00 ET
Bill Ackman is one of the most followed investment managers in the market today, and for good reason. His Pershing Square Holdings fund has produced annualized returns of 14.9% from its founding in 2004 through 2025 based on its stock price, handily beating the S&P 500 in that time.
Meanwhile, Greg Abel is better known for his managerial acumen than for his investing chops. Nonetheless, he's now in charge of Berkshire Hathaway 's (NYSE: BRKA) (NYSE: BRKB) massive $330 billion equity portfolio (with an extra $380 billion in cash on the sidelines).
The two found themselves on opposite sides of a trade last quarter. While Abel was adding to Berkshire's position in Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) , Ackman was selling the shares he'd held since 2023. Ackman completed selling all of Pershing Square's Alphabet shares in April; meanwhile, the stock is suddenly Berkshire's fifth-largest position, representing a significant bet from Abel.
