Warren Buffett's Successor, Greg Abel, Has 63% of Berkshire Hathaway's $355 Billion Portfolio Invested in Just 5 Standout Stocks

Greg Abel, who took over as Berkshire Hathaway CEO on December 31, 2025, maintains Warren Buffett's portfolio concentration strategy with 63% ($222.3 billion) of the $355 billion portfolio invested in just five stocks. While Abel shares Buffett's focus on indefinite core holdings like Coca-Cola and American Express, he is distinctly more bullish on technology stocks including Apple and Alphabet. Berkshire has reduced its Bank of America position by 50% since mid-2024 as the stock no longer trades at a discount to book value.
