Berkshire Hathaway 13F Filing Reveals Warren Buffett's Secret Stock

Berkshire Hathaway's Q2 13F filing revealed a significant new $1.6 billion stake in UnitedHealth Group (UNH), which saw its shares surge over 10% after hours, alongside new smaller positions in homebuilders D.R. Horton (DHI) and Lennar (LEN), Allegion (ALLE), Lamar Advertising (LAMR), and Nucor (NUE), and increased exposure to Chevron (CVX). Concurrently, Berkshire fully exited its T-Mobile (TMUS) holding, nearly halved its Charter Communications (CHTR) stake, and made smaller reductions to its large Apple (AAPL) and Bank of America (BAC) positions, indicating a strategic reallocation away from some telecom and financial assets towards healthcare, energy, and housing.

Analysis

Berkshire Hathaway's second-quarter 13F filing reveals a significant strategic portfolio reallocation, highlighted by the disclosure of a new $1.6 billion position in UnitedHealth Group (UNH), a stake likely accumulated since the fourth quarter of the prior year. This move, which sent UNH shares up over 10% in extended trading, signals a major new conviction in the healthcare sector. Simultaneously, Berkshire established a strong bullish stance on the U.S. housing market by initiating a position in D.R. Horton (DHI) and substantially increasing its stake in Lennar (LEN) from 150,000 to approximately 7 million shares. These acquisitions were funded in part by a continued pivot away from telecommunications, evidenced by the complete liquidation of a $1 billion holding in T-Mobile (TMUS) and the sale of nearly half its Charter Communications (CHTR) stake. Furthermore, Berkshire modestly trimmed its largest positions, selling 20 million Apple (AAPL) shares and 26 million Bank of America (BAC) shares, continuing a trend of paring back these holdings. The reduction in BAC aligns with a broader Q1 move to reduce banking exposure. In contrast, the firm reinforced its bet on energy by adding 3 million shares to its Chevron (CVX) position, while foundational investments in Coca-Cola (KO) and American Express (AXP) remained untouched, indicating their continued role as core long-term holdings.

Key Decisions for Investors

• Investors should closely examine UnitedHealth (UNH) and the broader healthcare sector, as Berkshire's $1.6 billion investment, built covertly, signals a strong, high-conviction bet.
• The new positions in homebuilders D.R. Horton (DHI) and Lennar (LEN) suggest a bullish outlook on the housing market, warranting a review of exposure to this sector.
• The complete exit from T-Mobile (TMUS) and a major reduction in Charter Communications (CHTR) serve as a strong cautionary signal for the telecommunications industry, prompting a re-evaluation of holdings in this space.
• While the trims in Apple (AAPL) and Bank of America (BAC) are minor, the consistent selling trend suggests a strategic reduction of concentration risk, a factor for long-term holders to monitor in subsequent filings.
