Greg Abel’s first major move at Berkshire: cutting Chevron exposure and lifting a new top holding

Berkshire Hathaway’s succession story is being written, at least in part, through portfolio moves. A market report says Greg Abel, the company’s longtime heir-in-waiting and now a top executive running day-to-day decisions, has started his tenure by trimming Berkshire’s Chevron stake and raising its position in Alphabet, the parent of Google.

The report characterizes the Chevron cut as a significant reduction. It says Berkshire’s holding in Chevron was cut by 35%, framed as a deliberate redeployment of capital away from Berkshire’s long-standing oil-and-gas exposure.

In the same update, the report says Berkshire increased its Alphabet position enough to make it the company’s No. 5 largest holding. The framing emphasizes a “foundational sustainable moat” tied to Alphabet’s business model and also points to “serious artificial intelligence (AI) ambitions,” linking the decision to a longer-duration technology thesis rather than a near-term commodity cycle bet.

Berkshire’s portfolio decisions are closely watched because they can announcement how the succession plan is translating into investment priorities. The company has historically favored businesses with durable advantages, ample cash generation, and clear long-term economics, even if the market’s appetite for those themes changes over time.

This latest shift, if it mirrors the direction suggested in the report, would be consistent with a broader pattern in Berkshire’s stock picking: rebalancing among large, liquid public companies where the investment case is built around what management believes will persist. The Chevron reduction also suggests Berkshire is willing to reduce exposure even to familiar holdings when it chooses to reweight the portfolio.

Even so, important context is missing from the market report. It does not provide details on the size of Berkshire’s total Chevron position before and after the change beyond the percentage figure, nor does it outline whether the Alphabet purchase came from new buying, additional trimming of other holdings, or a reallocation within the same set of positions.

Berkshire also did not provide additional figures in the cited post. The report stops short of describing the exact timing of the trades, the price paid or received, or whether management viewed the Chevron cut as a near-term risk adjustment, a valuation-driven decision, or a portfolio concentration choice.

Investors will likely watch Berkshire’s next major disclosure for confirmation and granularity, including the updated weights of Chevron and Alphabet in the overall portfolio. A key question for the market will be whether the changes represent a one-time rebalance or the beginning of a broader shift in how Abel’s leadership shapes Berkshire’s large public-stock holdings.
