Berkshire Hathaway Reports $299.3 Billion in Stock Holdings as of September 30, 2026, with Apple Remaining the Largest Position

Berkshire Hathaway has declared a stock portfolio valued at $299.3 billion as of September 30, 2026, according to its 13F filing.

Warren Buffett's Investment Philosophy at Berkshire Hathaway

Warren Buffett adheres to a strategy known as "value investing," which involves purchasing publicly traded companies at prices below their intrinsic value. He focuses on businesses with stable economic models, recurring cash flow, and strong management teams. The current portfolio reflects this approach: over half of the assets are invested in well-known companies, enduring brands, and dominant market positions. Historical performance shows that this strategy has delivered an average annual return exceeding 10% since the 1970s, significantly outpacing most benchmark indices. Preferred sectors include financial services, consumer goods, information technology, and energy, with a particular focus on companies capable of withstanding economic cycles.

Key New Positions and Strengthens

The third-quarter 2026 filing reports no new acquisitions among the top ten holdings. The declared values correspond to previously held positions, indicating that the fund did not significantly increase its stakes in these stocks during the prior quarter. Apple Inc. remains the largest holding at $65.95 billion, representing 22.0% of the portfolio, followed by American Express ($51.28 billion, 17.1%). Alphabet, Coca-Cola, Bank of America, Chevron, Occidental, Chubb, Moody’s, and Kraft Heinz round out the top ten, collectively accounting for over 90% of the total declared value. The 13F form does not indicate any percentage changes, as it only lists amounts as of the quarter's end.

Cuts and Exits – What Buffett/Management is Leaving Behind

The filing mentions no full exits or significant reductions in any listed positions. The absence of减持 lines suggests that management did not liquidate substantial portions during the quarter. Positions outside the top ten total $26.8 billion, representing 9% of the portfolio, but the filing does not detail their identities or potential movements. Thus, based on available information, the portfolio composition remains stable, with no indication of major disengagement from a sector or specific company.

Limitations of the 13F: What This Filing DOESN'T Say

The 13F form only includes long equity positions in U.S. stocks, with a filing deadline of 45 days after the end of the quarter. It excludes short positions, option contracts, unlisted securities, international investments, and indirect holdings through mutual funds. Consequently, the actual size of Berkshire Hathaway's portfolio, which also includes private investments, bonds, and non-listed assets, is not reflected in this filing. Additionally, the 13F does not specify purchase prices, acquisition dates, or holding objectives, limiting insights into short-term strategy.
