Berkshire Hathaway, the investment conglomerate led by Warren Buffett, reported a $299.3 billion market portfolio for Q3 2026, spread across 26 positions as per the 13F-HR filing submitted on August 14, 2026.
Warren Buffett's Investment Philosophy at Berkshire Hathaway
Warren Buffett employs a so-called "value investing" approach, meaning he seeks businesses where the market price is below the estimated intrinsic value. This method relies on in-depth analysis of cash flows, sustainable profitability, and management quality. The fund favors companies with durable competitive advantages ("moats"), the ability to generate recurring cash flows, and reliable governance. Historically, the strategy combines positions with strong visibility (consumer brands) and financial sector stocks, reflecting a preference for stability and long-term resilience.
Major New Positions and Strengthenings
The 13F filing details the top ten largest positions, all held in common stock. Apple Inc. is the largest position with $65.95 billion (22.0% of the portfolio), corresponding to 227,917,808 shares. American Express Co. follows with $51.28 billion (17.1% of the portfolio) and 151,610,700 shares. Alphabet Inc. represents $37.76 billion (12.6%) and 105,979,600 shares. Coca-Cola Co. is fourth with $32.51 billion (10.9%) and 400,000,000 shares. Bank of America Corp. comes in at $27.54 billion (9.2%) and 483,394,015 shares.
The remaining top ten positions include: Chevron Corporation ($13.99 billion, 4.7% of the portfolio, 84,375,856 shares), Occidental Petroleum Corp. ($12.87 billion, 4.3% of the portfolio, 264,941,431 shares), Chubb Limited ($11.67 billion, 3.9% of the portfolio, 34,249,183 shares), Moody’s Corp. ($11.17 billion, 3.7% of the portfolio, 24,669,778 shares), and Kraft Heinz Co. ($7.69 billion, 2.6% of the portfolio, 325,634,818 shares). The remaining 16 positions total $26.8 billion, approximately 9% of the portfolio.
These holdings span various sectors: technology (Apple, Alphabet), financial services (American Express, Bank of America), consumer goods (Coca-Cola, Kraft Heinz), energy (Chevron, Occidental), and insurance (Chubb). The diversification reflects Buffett's preference for stable cash flows, recognized brands, and strong market positions.
Reductions and Exits - What Buffett is Leaving Behind
The 13F filing does not detail changes to each position compared to the previous quarter. No specific stock is indicated as having been entirely sold, and no numerical reductions are provided in the document. Without explicit information, it's impossible to specify which positions were reduced or eliminated.
Limitations of the 13F: What This Filing Doesn’t Say
The Form 13F only lists long positions in U.S. stocks, with a filing deadline of 45 days after the end of the quarter. Short positions, options, futures contracts, and non-U.S. listed securities are not included. Additionally, the filing does not reveal the amounts invested in Berkshire Hathaway's private subsidiaries or any potential hedging strategies. Thus, the picture presented reflects only a portion of the group's total exposure.
