Berkshire Hathaway, under the leadership of Warren Buffett, reported a total portfolio of $299.3 billion as of September 30, 2026, distributed across 26 positions according to the 13F-HR filing submitted on August 14, 2026. Berkshire Hathaway: Warren Buffett's Investment Philosophy Warren Buffett adheres to a value investing philosophy, which involves purchasing shares of companies whose market price is below their estimated intrinsic value. He focuses on businesses with sustainable competitive advantages, high-quality management, and the ability to generate recurring cash flows. Berkshire Hathaway's track record spans decades, with net worth growth significantly outpacing that of the S&P 500. Buffett's investment style combines a macroeconomic approach—selecting sectors resilient to economic cycles—and an orientation toward financial services, consumer goods, and energy sectors, reflecting his historical preferences. Major New Positions and Strengths The Q3 2026 13F filing reveals the top ten positions, totaling $262.5 billion, or 87.7% of the reported portfolio. Apple Inc. leads with $65.95 billion (22.0% of the portfolio), representing 227,917,808 shares. American Express Co. follows with $51.28 billion (17.1% of the portfolio) and 151,610,700 shares. Alphabet Inc. is third with $37.76 billion (12.6% of the portfolio) and 105,979,600 shares. Coca-Cola Co. holds $32.51 billion (10.9% of the portfolio) across 400,000,000 shares. Bank of America Corp. is at $27.54 billion (9.2% of the portfolio) with 483,394,015 shares. Chevron Corporation, Occidental Petroleum Corp., Chubb Limited, Moody’s Corp., and Kraft Heinz Co. complete the top ten with respective allocations of 4.7%, 4.3%, 3.9%, 3.7%, and 2.6% of the portfolio. The remaining 16 positions total $26.8 billion (8.9% of the portfolio), but their specific titles and amounts are not detailed in the provided data. Reductions and Exits — What Buffett is Exiting The 13F filing does not explicitly provide information on reductions of existing positions or complete exits during the quarter. Without a comparison to the previous filing, it's impossible to identify which securities were sold or reduced. Therefore, based on available information, no reductions or exits can be confirmed from the Q3 2026 filing. Limitations of the 13F: What This Filing DOES NOT Say The 13F filing has several important limitations for investors. First, it is subject to a 45-day lag after the quarter closes, meaning positions may have changed since the reference date. Second, the form only includes long U.S. equity positions; it excludes short positions, options, futures contracts, and securities held through offshore vehicles. Third, the reported values reflect shares held directly or through subsidiaries but do not account for indirect holdings or private fund investments. Finally, the 13F does not indicate the purchase price, acquisition date, or holding objectives, limiting the interpretation of short-term strategy.
