Warren Buffett’s Berkshire Hathaway Quietly Builds UnitedHealth Stake While Trimming Apple and Bank of America

Global FinDesk — Warren Buffett’s investment powerhouse, Berkshire Hathaway, has disclosed a notable new position in healthcare leader UnitedHealth Group, alongside adjustments to several long-standing holdings, according to its latest SEC 13F filing for the second quarter.

By the end of Q2, Berkshire held 5 million shares of UnitedHealth Group (UNH), worth approximately $1.6 billion. The move follows months of discreet accumulation, beginning late last year, after Berkshire obtained regulatory permission to build its position privately—helping to prevent a sudden price surge. Shares of UnitedHealth jumped over 10% in after-hours trading following the disclosure.

The filing also revealed fresh, smaller investments in:

• Allegion (ALLE) – Security products manufacturer
• D.R. Horton (DHI) – Leading U.S. homebuilder
• Lamar Advertising (LAMR) – Outdoor advertising company
• Nucor (NUE) – Steel production giant

Each of these stocks experienced after-hours gains.

Meanwhile, T-Mobile (TMUS) was the only complete exit from Berkshire’s portfolio this quarter, with the firm selling its entire $1 billion stake. Berkshire also cut nearly half of its holding in Charter Communications (CHTR).

In other notable shifts:

• Sold 20 million shares of Apple (AAPL), reducing its 300 million share stake.
• Sold 26 million shares of Bank of America (BAC), trimming its position from 630 million shares.
• Increased holdings in Chevron (CVX) by 3 million shares.
• Maintained long-time investments in Coca-Cola (KO) and American Express (AXP) without change.

Earlier this year, Berkshire reduced its banking exposure by fully exiting Citigroup (C) and trimming stakes in Bank of America and Capital One (COF). However, the firm expanded its consumer and food holdings, adding to positions in Constellation Brands (STZ) and Domino’s Pizza (DPZ).

Homebuilding appeared to be a key theme in Q2, with Berkshire’s purchase of 7 million shares of Lennar (LEN)—a major increase from its previous 150,000-share position.

Despite recent volatility, Berkshire shares have dropped around 11% since Buffett’s announcement in May that he will step down as CEO at the end of 2025. Year-to-date, however, the stock remains up nearly 6%.
