Berkshire Hathaway Holds $299.3B in Marketable Securities as of September 30, 2026. Apple Maintains 22% Lead, Followed by American Express and Alphabet.
Berkshire Hathaway, the conglomerate led by Warren Buffett, filed its quarterly 13F with the SEC, revealing a marketable securities portfolio of $299.3 billion as of September 30, 2026. The fund holds 26 positions, with the top ten representing approximately 89% of the total value. This filing, which is mandatory within 45 days following the end of the quarter, provides insight into the investment decisions of one of the world's most closely watched investors.
Warren Buffett, the legend of value investing, focuses on businesses with sustainable competitive advantages, competent management, and reasonable valuation. His philosophy, inspired by Benjamin Graham, involves purchasing and holding high-quality stocks for the long term, often in defensive sectors such as consumer goods, finance, and energy. Berkshire Hathaway boasts an exceptional track record: since 1965, its annual compounded return has far exceeded that of the S&P 500, though past performance is not indicative of future results. The current portfolio reflects this approach: technology giants (Apple, Alphabet), financial institutions (American Express, Bank of America, Moody's), consumer goods companies (Coca-Cola, Kraft Heinz), and energy firms (Chevron, Occidental Petroleum).
Major New Positions and Strengthens
The 13F filing does not specify exact buys and sells, but changes in stock holdings compared to the previous quarter can identify movements. According to available information, Berkshire has maintained its massive position in Apple, holding 227,917,808 shares worth $65.95 billion (22% of the portfolio). No major new positions are reported in the provided data, but notable increases include American Express, now valued at $51.28 billion (17.1%), and Alphabet, third on the list at $37.76 billion (12.6%). These increases in value may result from stock appreciation or additional purchases. The fund has also increased its stake in Occidental Petroleum, which now weighs $12.87 billion (4.3%), aligning with Buffett's energy strategy.
Cuts and Exits - What Buffett is Leaving Behind
No full exits are listed in the provided data. However, some positions have seen their relative value decrease, such as Bank of America, which remains at 9.2% of the portfolio with $27.54 billion, and Chevron, now at 4.7% with $13.99 billion. These declines may result from partial sales or underperformance of stock prices. The fund did not divest any significant positions in Q3 2026, according to available information. It is worth noting that Berkshire still holds Kraft Heinz, a historically reduced position but still representing $7.69 billion (2.6%).
Limitations of the 13F: What This Filing Doesn't Say
While informative, the 13F form has significant limitations. Holdings are reported with a 45-day lag after the end of the quarter, meaning the data may be outdated at the time of publication. Additionally, it only covers long positions (buy-side holdings); short positions (short sales) and options are not included. Investments outside the U.S., such as foreign shares listed on non-U.S. exchanges, are also excluded. Finally, the 13F does not reveal the manager's intentions: an increase in value may result from purchases or rising stock prices.
