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?

Since becoming CEO of Berkshire Hathaway, Greg Abel has maintained high concentration in five blue-chip stocks (Apple, American Express, Alphabet, Bank of America, and Coca-Cola), which now represent 60% of the portfolio. While this concentration is largely inherited from Warren Buffett's long-term investments, the article argues that downside risk is manageable given Berkshire's strong financial position. The greater concern is whether Abel can match Buffett's stock selection track record going forward.
