Berkshire Hathaway’s Q2 portfolio reshuffle lifts Alphabet and Delta, trims Bank of America

Berkshire Hathaway made notable adjustments to its stock portfolio in the most recent quarter, according to a market review published Wednesday. The changes, described as some of the biggest in Berkshire’s holdings for the period, included adding to positions in Alphabet and Delta Air Lines while reducing its investment in Bank of America.

The review characterizes Berkshire’s moves as a “load up” on Alphabet and Delta, implying larger purchases or stronger positions in those stocks during the quarter. At the same time, the company made a “sizeable reduction” in its Bank of America stake, a shift that indicates Berkshire cut back on its exposure to the U.S. banking sector relative to its prior weighting.

Alphabet, the parent company of Google, sits at the center of the digital advertising and cloud computing markets. Berkshire’s decision to expand a holding in Alphabet fits with a broader pattern among long-hold investors: adding to widely used platforms when they are still viewed as durable businesses rather than short-cycle trades.

Delta Air Lines, a major U.S. carrier, represents an exposure to airline demand and pricing power, as well as costs tied to fuel, labor, and fleet management. Berkshire’s increase in Delta suggests management saw enough stability in the business fundamentals to justify a larger position, even as the airline industry remains sensitive to economic slowdowns and disruptions.

Bank of America is one of the largest U.S. consumer and commercial lenders. Berkshire has long held a meaningful financials position, and trimming it can reflect several possibilities, including a desire to reduce concentration risk, changes in expected returns, or a shift in relative attractiveness versus other opportunities. The key point from the reported update is direction, not the specific magnitude: the reduction is described as sizable, while the additions to Alphabet and Delta are described as substantial.

Berkshire Hathaway is not a company that regularly telegraphs quarter-by-quarter portfolio transactions in the way active mutual funds do. Instead, its investment style typically emphasizes long-term ownership of operating businesses and selected stocks, with changes that can be driven by valuation, risk balance, and management’s assessment of how a business will perform over time.

Still, the market review does not provide the detailed transaction breakdown that investors often want for deeper analysis, such as the exact number of shares added or trimmed, the average cost basis, or whether Berkshire increased positions broadly across its entire holding or only in specific lines. It also does not clarify whether the changes were the result of new purchases, partial sales, or valuation-driven fluctuations between quarters. Those details will matter for anyone trying to distinguish between a strategic re-weighting and a more tactical rotation.

Going forward, traders and long-term shareholders will likely watch whether the new or increased exposures keep trending upward in subsequent quarters and whether the Bank of America cut proves to be a pause or the start of a broader reduction in financials. Another practical question is whether the Alphabet and Delta additions are supported by continued conviction in future filings, or if they represent a one-quarter adjustment as Berkshire reallocates capital.
