Warren Buffett's Berkshire Hathaway Holds $299.3 Billion in Stocks, Apple Represents 22% of Q3 2026 Portfolio

Berkshire Hathaway, under the leadership of Warren Buffett, reported a marketable portfolio of $299.3 billion as of the last day of the third quarter in 2026, spread across 26 positions.

Warren Buffett's Investment Philosophy at Berkshire Hathaway

According to public information, the company led by Warren Buffett favors a long-term investment approach focused on holding stocks of high-quality businesses with sustainable competitive advantages. This philosophy is reflected in concentrated positions in companies with strong cash-flow generation, often listed in the United States, with a preference for sectors such as technology, financial services, consumer staples, and energy. The performance track record shows that the fund has maintained significant positions for several decades, illustrating the "buy-and-hold" discipline advocated by its manager.

Key New Positions and Strengths

The 13F-HR filing on August 14, 2026, does not detail changes from the previous quarter but lists the top ten positions at the end of the quarter. Apple Inc. is the dominant holding with $65.95 billion, representing 22.0% of the portfolio, equivalent to 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 in third place, valued at $37.76 billion (12.6% of the portfolio) for 105,979,600 shares. Coca-Cola Co. holds $32.51 billion (10.9% of the portfolio), corresponding to 400,000,000 shares. Bank of America Corp. represents $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 portfolio weights of 4.7%, 4.3%, 3.9%, 3.7%, and 2.6%. These figures illustrate a diversified exposure across technology, financial services, basic consumer goods, energy, and insurance sectors, reflecting the fund's sector diversification strategy.

Cuts and Exits - What Buffett/the Manager is Leaving Behind

The 13F-HR report mentions no exits or reductions beyond the simple statement of holdings as of the closing date. Without comparative data from the previous quarter, it's impossible to identify specific divestments or disengagements. Thus, based on available information, the portfolio remains composed of the same listed securities without indication of major sales.

The Limits of 13F: What This Filing DOES NOT Say

The 13F form, required by the SEC, only includes long positions in U.S. listed stocks, reported within 45 days after the end of the quarter. It excludes short positions, options, bonds, private placements, as well as shares held through subsidiaries or outside the United States. Consequently, the table presented does not reflect the entirety of Berkshire Hathaway's assets, which also holds significant unlisted investments, insurance activities, and real estate investments not covered by the 13F. Additionally, the figures provided correspond to closing prices on the last day of the quarter and may fluctuate between the filing date and the investor's reading.
