Warren Buffett's Successor, Greg Abel, Jettisoned Amazon Earlier This Year and More Than 6X'd Berkshire's Stake in the "Apple" of His Eye

Under new CEO Greg Abel, Berkshire Hathaway reduced or exited 16 holdings in Q1, including Amazon, while expanding its Alphabet position from $5.59B at Dec. 31 to $36.37B by Sept. 25—a 550% increase. The article attributes Amazon's sale partly to profit-taking after a roughly 150%-200% gain since 2019 and potentially to former investment manager Todd Combs' departure. Alphabet's appeal centers on its search and advertising moat, more than 91% global search share, and AI-driven cloud growth, with Google Cloud revenue up 82% year over year in the June-ended quarter.

Analysis

The portfolio changes are more informative for Berkshire’s post-succession capital-allocation process than for Amazon’s fundamentals. A disposal tied to an investment-manager transition should not be read as a negative read-through on AWS or retail economics; any forced-flow pressure is likely short-lived relative to AMZN’s liquidity. The more relevant second-order effect is that Abel may rationalize legacy satellite positions into a smaller group of high-conviction platform assets, increasing BRK.A/BRK.B’s sensitivity to mega-cap technology valuations and reducing the historical diversification discount embedded in the equity book.

A larger Alphabet position is a marginal sentiment and ownership-support catalyst, but it does not change Google’s operating outlook. The investable question is whether Cloud’s incremental gross profit can outpace AI infrastructure depreciation and traffic-acquisition-cost pressure over the next 2-4 quarters; without that conversion, investors will re-rate the growth as capex-intensive rather than cash-generative. A concentrated Berkshire buyer can also tighten the near-term float, but this is a weak standalone reason to chase GOOG after disclosure-driven upside.

The cleaner relative-value expression is GOOG versus AMZN only if Alphabet sustains superior cloud margin expansion while Amazon’s AI monetization remains offset by heavy infrastructure investment. Consensus may underappreciate that both companies face the same AI-capex cycle: a growth surprise without free-cash-flow conversion is not necessarily multiple-accretive. This thesis is falsified if AWS reaccelerates while its operating-margin trajectory improves faster than Google Cloud’s, or if Alphabet materially increases 2027 capex guidance without a corresponding backlog or margin uplift.

Key Decisions for Investors

• Do not trade AMZN solely on Berkshire’s sale; treat it as a portfolio-management event. Reassess only if AWS growth decelerates below the broader cloud cohort for two consecutive quarters or management cuts infrastructure-return expectations.
• Initiate a 1-3 month modest long GOOG / short AMZN pair only after the next cloud earnings prints confirm a widening Google Cloud versus AWS operating-margin differential. Target 8-12% relative return; stop if AWS revenue growth exceeds Google Cloud growth by more than 10 percentage points with positive margin expansion.
• Maintain a watch on BRK.B rather than adding on the portfolio news. A sustained shift toward concentrated mega-cap technology exposure could improve look-through growth but raises drawdown beta; require evidence of continued operating-business cash deployment or accretive repurchases before underwriting multiple expansion.
• For existing GOOG longs, use the next capex and free-cash-flow guidance update as the key catalyst. Take profits or hedge if AI-related capex rises materially while Cloud operating margin fails to expand sequentially, as that would challenge the cash-flow conversion thesis within 6-12 months.
