Warren Buffett's Successor, Greg Abel, Overhauled Berkshire Hathaway's Portfolio and Has 61% of Its Assets Invested in Just 5 Stocks

Greg Abel, who took over as CEO of Berkshire Hathaway on December 31, 2025, has significantly restructured the company's $330 billion investment portfolio. The new portfolio is highly concentrated, with 61% of assets invested in just five stocks: Apple, American Express, Coca-Cola, Bank of America, and Alphabet. Abel removed 16 positions in his first quarter, representing a third of Buffett's final holdings, while maintaining Buffett's 'indefinite' holdings and tripling Berkshire's stake in Alphabet.
