Berkshire Hathaway Reports $299.3B in Q3 2026, Apple Still Leads
In Q3 2026, Berkshire Hathaway holds $299.3 billion in listed stocks, with Apple making up 22.0% of the portfolio. The fund strengthens its position in Alphabet and reduces Bank of America.
Berkshire Hathaway, the conglomerate led by Warren Buffett, filed its 13F form with the SEC for Q3 2026, revealing a total stock portfolio valued at $299.3 billion. The fund holds 26 positions, with the top ten representing 91% of the total value. The filing, dated August 14, 2026, shows significant concentration in large-cap American equities, with Apple leading at $65.95 billion, or 22.0% of the portfolio.
Warren Buffett, the legend of value investing, focuses on strong companies with sustainable competitive advantages, capable management, and reasonable valuations. Under his leadership since 1965, Berkshire Hathaway has generated an average annualized return of approximately 20% over the long term, outperforming the S&P 500. The current portfolio reflects this approach: consumer staples (Coca-Cola, Kraft Heinz), financial institutions (American Express, Bank of America, Moody's), and energy companies (Chevron, Occidental Petroleum). Buffett's philosophy is to buy and hold with limited rotation, though tactical adjustments are evident in this 13F filing.
Key New Positions and Strengthens
The Q3 2026 13F shows a significant increase in Alphabet Inc, now valued at $37.76 billion (12.6% of the portfolio). The holder of 105,979,600 shares increased its position from the previous quarter, though exact figures on the variation are not provided. This upstep fits Buffett's trend of investing in high-market-power technology companies after avoiding the sector for years. No new positions were created during the quarter, according to available information. Notable increases include a larger stake in Occidental Petroleum, now valued at $12.87 billion (4.3% of the portfolio), with 264,941,431 shares held. This strengthening reflects Buffett's confidence in the energy sector, particularly in oil and gas.
Cuts and Exits: What Buffett is Leaving Behind
The filing reveals a substantial reduction in Bank of America Corp, now valued at $27.54 billion (9.2% of the portfolio), with 483,394,015 shares. While the absolute value remains high, the decrease from the previous quarter is noticeable, though exact figures on the cut are not specified. This partial sale could reflect taking profits after the stock's rise. No full exits are reported in the filing, according to available information. Other reductions, if any, are not detailed in the provided data. It's worth noting that the portfolio remains concentrated in long-term positions with limited rotation, consistent with Buffett's strategy.
Limitations of the 13F: What This Filing Doesn't Say
The 13F form, despite its informative nature, has significant limitations for individual investors. First, it is filed within 45 days after the end of the quarter, meaning the data reflects positions as of the last day of the quarter (September 30, 2026) but is published with a lag. Moves made after that date are not visible. Additionally, the 13F only covers long equity positions; it does not disclose short positions, options, or investments outside the U.S. For example, derivatives or bonds are not included. Finally, the form does not provide purchase costs or detailed performance, only market value. For a comprehensive analysis, further data is needed.
