Berkshire Hathaway CEO Overhaul: Abel Exits Amazon, Doubles Alphabet, Adds Delta Airlines

Berkshire Hathaway's first-quarter portfolio filing reveals that Greg Abel, who took over as CEO after Buffett's December 2025 retirement, is executing a notably different investment philosophy than his predecessor. The new CEO exited the company's entire Amazon position while substantially increasing the Alphabet (Google) holding to roughly 7 percent of the portfolio. Simultaneously, he initiated a $2.6 billion stake in DeltaHow much an option's price changes per $1 move in the underlying. Air Lines, making it Berkshire's 14th-largest holding and marking the first airline bet by the conglomerate in years. These moves are not incremental adjustments; they signal a deliberate rotation away from mega-cap concentration and toward value and cyclical positioning.

The Amazon exit is particularly noteworthy given Buffett's long-standing admiration for Jeff Bezos and the company's dominant market position. Abel's decision to trim or exit entirely suggests either a conviction that the stock is overvalued at current levels relative to growth prospects, or a broader skepticism about mega-cap tech concentration after the six-week AI rally. The Alphabet boost, meanwhile, is a bullish signal on Google's AI moatA sustainable competitive advantage that protects long-term returns on capital. and potential to monetize search and advertising in an AI-driven future. The DeltaHow much an option's price changes per $1 move in the underlying. purchase is more puzzling at first blush; airlines are cyclical, capital-intensive, and sensitive to energy prices. However, it signals Abel's willingness to hunt for value in beaten-down sectors, particularly as energy prices stabilize and travel demand remains resilient. Berkshire also sold $8 billion of Chevron shares in Q1 as oil stocks rallied, further underscoring a rebalancing from energy exposure.

The broader market implication is twofold. First, Abel's moves suggest that a mega-cap tech concentration trade may be near a natural limit, and even the most sophisticated allocators are rotating into value and diversification. Second, the bet on DeltaHow much an option's price changes per $1 move in the underlying. and other beaten-down cyclical names is a contrarian signal that the economy, despite inflationThe rate at which prices rise across an economy. fears and yield spikes, is not rolling over. The airline bet specifically is a wager on continued travel demand and a view that energy prices, while elevated, will not crush margins beyond current expectations. This runs counter to the prevailing bear narrative that higher rates and inflation will crush consumer spending and corporate earnings.

Skeptics note that Buffett was still nominally the chief investment officer during much of Q1, so some of these moves may reflect his thinking rather than Abel's independent conviction. However, the portfolio shift is large enough and deliberate enough to suggest a real change in philosophy. The exit from Amazon and boost to Alphabet align Abel's positioning with mega-cap tech exposure that is more diversified and less dependent on cloud computing and e-commerce. The market will now be watching Abel's next few filings closely to see if this is a one-time rebalancing or the start of a longer-term repositioning of Berkshire's sprawling portfolio.
