Greg Abel Has Kept 60% of Berkshire's $359 Billion Stock Portfolio in Just 5 Companies, Even After Eliminating 16 Other Positions in His First Quarter. Is That Concentration a Risk for Shareholders?
Berkshire Hathaway's top five stock holdings—Apple, American Express, Alphabet, Bank of America, and Coca-Cola—account for 60% of its U.S. equity portfolio. CEO Greg Abel has maintained high concentration, with Buffett's long-term investments contributing significantly. Apple's 50% drop would impact Berkshire's equity by $35.25 billion, but the company's large cash position and operating businesses mitigate liquidity risks. Abel's future investment performance remains a key uncertainty.
