Abel Concentrates Berkshire Portfolio on Five Standout Stocks

Greg Abel, Warren Buffett's successor at Berkshire Hathaway, has taken a significant shift in the company's investment strategy. In just over a year since taking over as CEO on Dec. 31, 2025, Abel has overseen the removal of 16 stocks from the portfolio and reduced six other positions. However, one trait that remains consistent with Buffett's approach is portfolio concentration.

Abel now holds 63% ($222.3 billion) of Berkshire Hathaway's $355 billion investment portfolio in just five standout stocks: Apple, American Express, Coca-Cola, Bank of America, and Alphabet (which includes both GOOGL and GOOG).

Coca-Cola and American Express have been long-standing holdings since 1988 and 1991, respectively. These companies have low cost bases and are generating annual yields on cost of 45% and 65%, making them unlikely to be sold.

The new CEO has also introduced tech stocks into the mix, a departure from Buffett's preference for consumer goods companies. Alphabet may become a core holding similar to Apple was for Buffett.
