The investment fund Berkshire Hathaway, led by legendary investor Warren Buffett, reported a total listed portfolio of $299.3 billion for Q3 2026. This filing, submitted to the SEC as part of Form 13F, lists 26 distinct positions, with the top ten concentrating the vast majority of the declared value. Warren Buffett's Investment Philosophy: Warren Buffett employs an approach known as "value investing," which involves purchasing companies whose market price is below their estimated intrinsic value. This strategy is based on in-depth fundamental analysis, the search for sustainable competitive advantages (or "moats"), prudent capital management, and a preference for stable cash flows. Buffett favors companies with strong balance sheets, manageable debt, and high-quality management. His investment horizon is long-term, often measured in decades, allowing him to navigate economic cycles without reacting to short-term market fluctuations. Track Record, Style, and Preferred Sectors: For decades, Berkshire Hathaway has generated returns superior to the market average through a combination of public equity investments and private company acquisitions. Buffett's style blends classic "value" positions (e.g., Coca-Cola, American Express) with growth-oriented bets on technology giants (e.g., Apple, Alphabet). The sectors most represented in the current portfolio are information technology, financial services, consumer staples, energy, and insurance, reflecting the diversification sought by the fund. Major New Positions and Strengthens: The August 14, 2026, Form 13F filing indicates the top ten largest positions by absolute value. Apple Inc. represents $65.95 billion, or 22.0% of the portfolio, with 227,917,808 shares held. American Express is in second place with $51.28 billion (17.1% of the portfolio) and 151,610,700 shares. Alphabet Inc., Coca-Cola Co., Bank of America, Chevron, Occidental Petroleum, Chubb Limited, Moody's Corporation, and Kraft Heinz Co. complete the top ten, accounting for over 80% of the declared value. The data provided does not specify whether these are new acquisitions or reinforcements compared to the previous quarter; Form 13F only details positions as of the quarter's end. The Reductions and Exits - What Buffett is Leaving: The same filing mentions no position reductions or complete exits. Form 13F only requires reporting equity positions held at the end of the quarter, without indicating changes from previous periods. Therefore, based on available information, it is not possible to identify significant divestments or sales during Q3 2026. Limitations of Form 13F - What This Filing DOES NOT Say: There are several constraints of Form 13F that should be understood. First, positions are reported with a 45-day delay after the end of the quarter, meaning the data reflects the situation on the last day of the quarter but may be outdated at the time of publication. Second, Form 13F only covers long equity positions listed in the United States; short positions, options, futures contracts, unlisted securities, and foreign investments are not included. Finally, the amount declared corresponds to the market value of the shares on the quarter's closing date, without considering potential off-balance-sheet obligations or hedging strategies.
