Preface

This article summarizes Berkshire Hathaway's notable portfolio changes in the second quarter, explaining how the conglomerate redirected capital into major technology, airline and housing positions.

Key figures, motivations and portfolio impacts are highlighted to show why these moves matter to investors and observers of Berkshire's evolving allocation approach.

Lazy bag

In the latest quarter, Berkshire significantly increased its Alphabet stake, lifting the Google parent into the firm’s three largest U.S.-listed equity holdings. Berkshire also grew positions in Delta Air Lines and several homebuilders, signaling renewed confidence in airlines and housing while reducing its cash reserve as capital was deployed.

Main Body

Berkshire Hathaway materially adjusted its equity portfolio during the second quarter, with a notable increase in its holding of Alphabet shares and additions to positions in the airline and homebuilding sectors. According to a regulatory filing covering the period ending in June, the Omaha-based conglomerate owned approximately 106 million shares of Alphabet, valued at roughly $37.9 billion. That represented an 83% increase in the position over the quarter and elevated Alphabet to the company’s third-largest U.S.-listed equity holding by market value, trailing only Apple and American Express.

The expansion in Alphabet largely reflects a substantial private stock purchase announced in early June, when Alphabet sought additional capital to support its significant investments in artificial intelligence infrastructure. That transaction accounted for a large portion of Berkshire’s increased exposure to Alphabet. Leadership commentary indicates that Warren Buffett, now serving as chairman, supported the bullish stance on Alphabet, and the move has the backing of CEO Greg Abel, who now runs day-to-day operations.

In addition to the tech position, Berkshire significantly boosted its airline exposure. The conglomerate increased its Delta Air Lines holding by 44% during the quarter, bringing the stake to 57.3 million shares valued at about $5.4 billion at the end of June. This marks a continued reengagement with the airline industry after Berkshire’s earlier divestitures of airline stakes during the onset of the COVID-19 pandemic. The renewed airline bets indicate confidence in the sector’s recovery and future prospects.

Housing-related investments also expanded. Berkshire raised its Class A shares of Lennar by nearly 30% to 13.1 million shares, valued at approximately $1.19 billion, while Class B shares increased by about 25% to roughly 298,000 shares. The company additionally disclosed a small new stake in D.R. Horton, holding 3,600 shares at quarter end. These moves deepen Berkshire’s exposure to homebuilding, a cyclical business that can benefit from improving demand and favorable lending conditions.

The second quarter marked a shift in Berkshire’s overall trading behavior. After 14 consecutive quarters as a net seller of equities, the firm emerged as a net buyer, recording nearly $20 billion in net stock purchases during the three-month span. That change coincided with a decrease in Berkshire’s cash balance, which fell to $365.5 billion at the end of June from a record $397.4 billion three months earlier. The decline in cash reflects a combination of increased investments in public equities, private placements and share repurchases.

Corporate activity during the quarter also included the completion of Berkshire’s acquisition of Taylor Morrison, a Scottsdale, Arizona-based homebuilder. This acquisition complements the firm’s growing public-market exposure to homebuilders and underscores a broader tilt toward housing-related assets.

Taken together, these moves portray a more active capital-deployment stance from Berkshire under its current management. The substantial purchase of Alphabet shares signals confidence in the company’s long-term growth prospects, particularly given its capital needs for AI infrastructure. Increased airline and homebuilder positions reflect selective reallocations into cyclical industries that Berkshire’s managers appear to judge attractively valued or positioned for recovery. The reduction in cash reserves shows a willingness to use available capital rather than maintain unprecedented liquidity levels.

For investors and market watchers, the changes serve as a useful window into Berkshire’s assessment of risk and opportunity across different sectors. While Berkshire’s portfolio adjustments do not guarantee future performance, they represent significant endorsements from a large, long-term oriented investor. Observers will likely watch subsequent filings and company disclosures for further clarity on whether these purchases mark the start of a longer-term strategic shift or a series of opportunistic allocations in response to market conditions.

In summary, the second-quarter activity shows Berkshire moving capital into major technology exposure via Alphabet, reinforcing positions in airlines and housing, and shifting from a long period of net selling to renewed buying while reducing its cash buffer.
