Berkshire Hathaway Reveals Its $299.3 Billion Stock Portfolio for Q3 2026

Berkshire Hathaway, the conglomerate led by Warren Buffett, filed its Form 13F with the SEC for the third quarter of 2026, revealing a portfolio of listed stocks valued at $299.3 billion. The filing, dated August 14, 2026, shows that the fund holds 26 positions, with the top ten representing the lion's share of its assets. This quarterly filing provides a snapshot of holdings as of the last day of the quarter, but with a 45-day lag.

Berkshire Hathaway: Warren Buffett's Investment Philosophy

Warren Buffett, the legend of value investing, has for decades favored businesses with strong fundamentals, sustainable competitive advantages, and disciplined management. His track record, marked by long-term outperformance versus the market, rests on a patient approach and risk aversion. Berkshire Hathaway primarily invests in defensive sectors such as consumer staples, financials, and energy, with a preference for companies generating stable cash flows. The current portfolio reflects this strategy, with significant concentration in large-cap U.S. equities.

Key New Positions and Strengthens

The Form 13F filing reports no major new positions during the third quarter. However, certain existing holdings were strengthened. Apple Inc. remains the top holding with $65.95 billion, or 22.0% of the portfolio, across 227,917,808 shares. American Express Co. follows with $51.28 billion (17.1% of the portfolio) and 151,610,700 shares. Alphabet Inc., the parent company of Google, constitutes the third holding with $37.76 billion (12.6%) and 105,979,600 shares. Coca-Cola Co. and Bank of America Corp. round out the top five, with respective allocations of $32.51 billion (10.9%) and $27.54 billion (9.2%). These five securities alone represent over 70% of the portfolio, highlighting its high concentration.

Among other significant holdings, Chevron Corporation ($13.99 billion, 4.7%), Occidental Petroleum Corp. ($12.87 billion, 4.3%), Chubb Limited ($11.67 billion, 3.9%), Moody's Corp. ($11.17 billion, 3.7%), and Kraft Heinz Co. ($7.69 billion, 2.6%) stand out. The remaining 16 positions total $26.8 billion, or approximately 9% of the total. While the filing does not detail changes from the prior quarter, the stability of major holdings suggests a long-term holding strategy.

Cuts and Exits - What Buffett is Leaving Behind

The Form 13F filing mentions no full exits from positions during the third quarter of 2026. However, certain reductions may have occurred, but the provided data does not allow for precise identification. In the absence of information on stock changes, it is impossible to confirm sales. Based on available data, the portfolio appears stable, with a preference for safe values. No major moves are reported in this filing.

Limitations of the 13F: What This Filing Does NOT Say

The Form 13F, mandatory for asset managers with over $100 million in assets, has significant limitations. First, it is filed within 45 days after the end of the quarter, meaning the data may be outdated at the time of publication. Second, it only covers long stock positions, excluding short sales, options, and bonds. Finally, it excludes holdings outside the U.S., potentially underestimating the fund's actual exposure. For a comprehensive view, investors should consult other documents, such as annual reports.
