Berkshire Hathaway increases Alphabet and Delta positions while trimming Bank of America, according to recent market coverage

Berkshire Hathaway’s investment activity in the second quarter showed a continued preference for large, widely held companies, with the conglomerate adding to its Alphabet position, building its stake in Delta Air Lines, and selling its Bank of America holding, according to market coverage published Tuesday.

The most prominent move involved Berkshire Hathaway’s Alphabet stake, which includes both voting and nonvoting shares of the search and advertising company. The report states that Berkshire increased its total Alphabet share count by about 80% over the quarter, reaching 106 million shares.

The coverage attributes part of the increase to a direct purchase from Alphabet in June, alongside additional activity in the open market. In other words, the quarter’s change was not limited to buying through exchange trading, but also included a transaction tied to Alphabet directly.

Berkshire Hathaway also expanded its Delta Air Lines position during the quarter, the report says, though it does not provide in the excerpted information the magnitude of the increase, the exact share count, or whether the purchases were made at particular times or through any single route.

At the same time, the report says Berkshire sold its Bank of America stake in the second quarter, reversing a position that Berkshire has held for years and that has often functioned as a bellwether of the firm’s broader view on financials and bank valuation.

Berkshire Hathaway’s pattern of moves typically reflects a mix of fundamental assessment and deal execution. For holdings like Alphabet, the appeal can center on cash generation and long-run business scaling, while the inclusion of both voting and nonvoting shares can matter for governance and economic exposure. With airline and banking exposures, management usually weighs the cycle and balance-sheet risk, along with how much of the expected returns the company can capture at current prices.

Sector context matters because Berkshire’s adjustments can be read by investors as a statement about the relative attractiveness of specific industries. Technology-heavy portfolios and cash-generating platforms have often attracted Berkshire when valuations look reasonable, while airlines, unlike many sectors, remain heavily influenced by fuel costs, labor terms, and demand trends. Financials, meanwhile, can swing materially with credit cycles and interest-rate expectations.

What is still unclear from the market coverage is the level of detail behind the trades. The excerpt does not specify the exact second-quarter share changes for Delta, the precise timeline and prices for each Alphabet purchase, or the size and method of the Bank of America sale beyond the claim that it occurred in the quarter. Berkshire also does not provide comprehensive trade narratives in the market excerpt, and full confirmation would typically come from updated quarterly regulatory disclosures. Investors looking for the definitive figures usually need to cross-check the quarter-end holdings reported in Berkshire’s filings.

Going forward, the key thing to watch is whether Berkshire’s next set of quarterly disclosures shows the same share counts and whether the company continues to concentrate in Alphabet and other large holdings, or whether the Delta expansion represents a one-quarter add rather than a longer-term shift. In parallel, attention will likely remain on whether the Bank of America exit indicates further retrenchment from financials or simply reflects a timing-driven disposition.
