Key Highlights
Greg Abel, who took over as chief executive of Berkshire Hathaway, has made his first significant portfolio adjustments as the firm’s top investment decision-maker, according to a recently filed 13F disclosure. In total, Abel exited positions in 16 stocks, including long-standing holdings such as Visa, Mastercard, Amazon, and UnitedHealth. These sell-offs represent a sharp reduction in some of Berkshire’s most visible equity bets.
At the same time, Berkshire dramatically increased its stake in Alphabet, Google’s parent company. The filing shows the conglomerate now holds approximately 58 million shares of Alphabet, roughly three times the size of its previous position. The move makes Alphabet one of Berkshire’s largest single equity holdings.
The filing covers the first quarter of 2026 — Abel’s initial full quarter as CEO following Warren Buffett’s retirement. While Berkshire has historically maintained a relatively concentrated portfolio, the scale and direction of these changes suggest a potential shift in the firm’s investment philosophy under new leadership. The market is now watching closely for further signals as Abel continues to put his stamp on the conglomerate’s massive equity portfolio.

Expert Insights
The first-quarter portfolio moves by Gregory Abel offer the clearest indication yet of how his investment style may differ from that of his predecessor. The near-tripling of the Alphabet stake represents a meaningful bet on the continued expansion of Google’s core advertising business and its emerging artificial intelligence capabilities. However, such a concentrated position also amplifies single-stock risk within Berkshire’s portfolio.
The simultaneous exit from stalwarts like Visa, Mastercard, and Amazon suggests Abel may be less inclined to hold a diversified basket of defensive and cyclical names. Instead, he appears to be rotating capital toward what he perceives as higher-conviction opportunities — a strategy that could produce outsized returns if Alphabet delivers, but may increase volatility.
Analysts note that one quarter of trading data does not constitute a long-term trend, and Abel may continue to adjust positions as he settles into the role. The broader implication for Berkshire shareholders is that the era of the “Buffett portfolio” may be evolving. Investors should closely monitor future filings for additional shifts that could further redefine the conglomerate’s investment identity.
