Warren Buffett successor triggers massive stock portfolio shakeup

Warren Buffett successor triggers massive stock portfolio shakeup as Greg Abel, Berkshire Hathaway’s new CEO, reshapes the conglomerate’s equity holdings in the first quarter. Abel initiated or significantly expanded positions in five stocks while cutting 16 others, reducing total holdings from 42 to 29 within one quarter. Berkshire’s equity portfolio changes involved buying $15.9 billion in stocks and selling $24.1 billion overall, covering its $263 billion equity portfolio. In the first quarter 2026 13F filing submitted to the SEC on May 15, Abel’s biggest addition was Alphabet, more than tripling Berkshire’s stake to about 58 million shares across Class A and C, worth roughly $16.6 billion by quarter-end. Berkshire also increased Delta Air Lines with 39.8 million shares valued at $2.6 billion, alongside stakes in Macy’s, The New York Times, and homebuilder Lennar. The reshuffle highlights a broad sector shift, including AI to airlines and deep-value retail.
