Berkshire Hathaway, the conglomerate led by Warren Buffett, reported a marketable portfolio of $299.3 billion as of September 30, 2026, consisting of 26 distinct positions according to the 13FâHR filing submitted to the SEC.
Warren Buffett employs a "value" investment approach: he seeks companies whose market price is below their estimated intrinsic value, prioritizing businesses with strong economic moats, the ability to generate consistent cash flows, and high-quality management. This method relies on in-depth fundamental analysis without systematic use of leverage. Historically, the fund has outperformed benchmark indices over the long term due to its focus on durable sectorsâfinancial services, consumer staples, information technology, and energy. The preference for U.S.-listed stocks reflects Buffett's familiarity with the regulatory framework and the transparency of financial information.
Key New Positions and Strengths
The Q3 2026 filing shows that the largest holding remains Apple Inc., valued at $65.95 billion (22.0% of the portfolio), with 227,917,808 shares held. This position highlights Buffett's appreciation for companies with massive user bases, integrated ecosystems, and high-margin capabilities. American Express Co. ranks second with $51.28 billion (17.1% of the portfolio) and 151,610,700 shares, illustrating Berkshire's interest in financial services with strong entry barriers and customer loyalty. Alphabet Inc. represents $37.76 billion (12.6% of the portfolio) and 105,979,600 shares, reflecting confidence in online advertising monetization and growth prospects tied to artificial intelligence and cloud computing.
Coca-Cola Co., with $32.51 billion (10.9% of the portfolio) and 400,000,000 shares, remains a historical cornerstone, mirroring Buffett's preference for stable cash flow-generating global brands. Bank of America Corp. occupies fifth place with $27.54 billion (9.2% of the portfolio) and 483,394,015 shares, indicating continued exposure to traditional U.S. banking. In the energy sector, Chevron Corporation ($13.99 billion, 4.7%) and Occidental Petroleum Corp. ($12.87 billion, 4.3%) are held, showcasing diversification into hydrocarbons despite energy transition uncertainties.
Insurers and rating agencies also feature in the top 10: Chubb Limited ($11.67 billion, 3.9%) and Moody's Corp. ($11.17 billion, 3.7%) demonstrate Berkshire's appetite for businesses with recurring premium flows and dominant market positions. Finally, Kraft Heinz Co. ($7.69 billion, 2.6%) rounds out the list, recalling the fund's interest in strong consumer product brands with stable margins. The remaining 16 positions total $26.8 billion, or approximately 9% of the portfolio, but their details are not provided in the filing summary.
Cuts and Exits - What Buffett/Legendre Is Exiting
The 13FâHR document does not specify changes in each position compared to previous quarters. Without direct comparison, it's impossible to identify reduced weightings or fully liquidated positions. The filing only includes holdings as of the quarter's end, without revealing intra-quarter movements. Therefore, any interpretation regarding reductions or exits must be based on prior reports, which are not included here.
Limitations of the 13F: What This Filing DOES NOT Say
A 13F filing must be submitted within 45 days after the end of the quarter, meaning the data reflects the situation as of the last day of the quarter but may be published weeks later. The form only lists long positions, excluding short sales, options, futures, and unlisted private placements. Additionally, securities held through subsidiaries or foreign investment vehicles are not always detailed, potentially masking part of the fund's actual exposure. Finally, the 13F does not reveal purchase prices, acquisition dates, or holding intentions, limiting the ability to assess the manager's timing strategy.
