Berkshire Hathaway’s recent portfolio adjustments, as detailed in its quarterly filings, triggered notable market movements on Monday. Investors are closely scrutinizing the conglomerate’s strategic shifts under its new leadership, particularly following the transition of operational control to CEO Greg Abel from the venerable Warren Buffett.
Portfolio Realignment and New Positions
A significant development revealed in the latest filings was Berkshire’s establishment of a substantial position in Delta Air Lines. The company acquired nearly 40 million shares of the airline, representing a market value of approximately $2.6 billion as of the close of the first quarter. This acquisition propelled Delta shares upwards by over 3% during Monday’s trading session. The move signals a strategic re-engagement with the airline sector for Berkshire, a departure from its prior exit from major airline holdings six years ago. At that time, Warren Buffett had divested the conglomerate’s entire airline portfolio, citing a permanent alteration in travel demand dynamics post-pandemic.
Furthermore, Berkshire initiated a new investment in Macy’s, acquiring a stake valued at roughly $55 million by the end of March. The department store’s stock experienced a more than 1% increase following the disclosure. In parallel, the conglomerate augmented its existing investment in Alphabet, the parent company of Google, elevating it to become Berkshire’s seventh-largest equity holding.
Divestitures and Strategic Departures
Conversely, Berkshire notably reduced its stake in Chevron. The filings also indicated a broad divestiture of several other stocks. This appears to be part of an effort to unwind positions previously managed by Todd Combs, who departed Berkshire at the end of 2025 to join JPMorgan. These divested holdings, including significant positions in Mastercard and Visa, were largely associated with Combs’ prior investment strategies. A complete exit from Amazon was also reported, a move widely attributed to the same portfolio management transition.
Additional sales from Berkshire’s portfolio included holdings in UnitedHealth Group, Aon, Pool Corporation, Domino’s Pizza, and Charter Communications. These divestitures underscore a period of portfolio recalibration, potentially reflecting a strategic pruning of legacy investments and a focus on new or expanded opportunities.
Leadership Transition and Buffett’s Influence
Despite the leadership transition, Greg Abel has emphasized his continued collaboration with Warren Buffett on investment decisions. Abel indicated that he remains in regular communication with the 95-year-old Buffett, seeking his insights and perspective on market dynamics and investment strategy.
Business Style Takeaway: Berkshire Hathaway’s latest portfolio maneuvers, particularly the re-entry into airlines and the adjustments in tech and financial services, signal a dynamic approach to capital allocation under new leadership. Investors should observe whether these shifts presage a broader strategic reorientation or represent a continuation of value-oriented investing principles, with potential implications for sector rotation and risk management across global markets.
