Abel Concentrates Berkshire Portfolio on Five Tech and Legacy Stocks

Greg Abel's investment strategy at Berkshire Hathaway has been characterized by portfolio concentration, favoring a handful of 'best ideas.' Following his appointment as CEO after Warren Buffett's retirement on Dec. 31, 2025, Abel oversaw the elimination of 16 stocks from the $355 billion portfolio in the March-ended quarter and reduced six other positions.

According to Aug. 5 closing values, 63% ($222.3 billion) of the portfolio is invested in just five standout stocks: Apple, American Express, Coca-Cola, Bank of America, and Alphabet. The largest holding is Apple, making up 20% of invested assets with a value of $70.88 billion.

Abel's portfolio is also notable for its legacy positions, including American Express and Coca-Cola, which have been continuous holdings since 1991 and 1988, respectively. These companies are generating annual yields on cost of 45% and 65%, respectively, and Abel has no reason to sell them.

While tech stocks were not a core part of Buffett's strategy, Abel is positioning Berkshire to take advantage of a technology-driven future. Alphabet may be the new 'core holding' that Apple was for Buffett, and Bank of America may be expendable due to its high interest sensitivity.
