Greg Abel is wasting little time putting his stamp on Berkshire Hathaway ‘s investment portfolio, reportedly moving to unwind positions tied to the departed lieutenant Todd Combs. The new chief executive has already sold stocks previously overseen by Combs after the longtime investment manager and Geico chief left for JPMorgan at the end of 2025, the Wall Street Journal reported. Combs had been one of two portfolio managers recruited by Warren Buffett to help oversee the conglomerate’s equity holdings. The move underscores how Abel is asserting control over Berkshire’s roughly $300 billion stock portfolio as he succeeded Buffett. Abel is unlikely to bring on a new investment manager to replace Combs, the WSJ said. Ted Weschler, the other investment manager, continues to oversee about 6% of the portfolio, Abel previously said in his first annual letter to shareholders. Berkshire does not disclose which manager is responsible for individual stock picks, making any attribution inherently speculative. Still, Combs had been widely associated with a tilt toward technology and financial names during his tenure, including stakes in VeriSign and Snowflake . Combs had also previously revealed Mastercard and Visa were the first stocks he bought after joining Berkshire, reflecting top holdings from his former hedge fund, Castle Point Capital. Berkshire’s recent trading has added to the speculation. The conglomerate dumped nearly 80% of its stake in Amazon in the fourth quarter of 2025, a position some had speculated as a Combs-influenced purchase. Abel said in his annual letter that the firm will remain focused on a tight group of core holdings, including Apple , American Express , Coca-Cola and Moody’s — companies he said are positioned to compound value over decades. Notably absent from that list was Bank of America , which had ranked as Berkshire’s third-largest holding at the end of 2025, raising fresh questions about its long-term role in the portfolio.
