Warren Buffett stepped down as Berkshire Hathaway chairman in September 2026, ending an era of exceptional returns (6,099,294% since 1965). New CEO Greg Abel faces the challenge of maintaining growth, but Berkshire's massive $1.1 trillion size makes repeating historical 19.7% annual returns virtually impossible. The company has underperformed the S&P 500 over the past decade and is sitting on $365.6 billion in cash while making strategic portfolio shifts.
Axe note: With Buffett gone, Berkshire Hathaway's future returns face the reality of size and shifting portfolio bets.
