Berkshire Hathaway reports $299.3 billion in positions, Apple remains the cornerstone at 22% of the portfolio
Under Warren Buffett, Berkshire Hathaway reports a $299.3 billion portfolio as of September 30, 2026, spread across 26 positions. Apple, American Express, and Alphabet account for over 50% of the total allocation.
Warren Buffett follows a "value investing" approach, which involves purchasing undervalued securities in companies with sustainable competitive advantages, stable cash flows, and reliable management. The fund favors long-term positions, often held for decades, to benefit from compounding profits. Historically, the strategy combines undervalued equities (e.g., Coca-Cola, American Express) with high-growth technology players (e.g., Apple, Alphabet) when their business models appear resilient. The financial sector, consumer goods, and energy regularly hold significant positions, reflecting Buffett's confidence in high-margin businesses with long-term earnings visibility. This philosophy results in a concentrated portfolio, where the top ten positions account for over 90% of total value.

Cuts and exits â what Buffett/the manager is abandoning
The Form 13F does not provide detailed information on changes in holdings compared to previous quarters. Without comparative data, it's impossible to identify specific securities that were reduced or fully liquidated during the third quarter of 2026. Based on available information, the filing only reflects the state of positions as of the end of the quarter, without indicating internal movements.
Limitations of the 13F: What this filing DOES NOT say
The Form 13F, required by the Securities and Exchange Commission (SEC), must be filed within 45 days of the end of the quarter and only includes long U.S. publicly traded equity positions. It excludes short positions, options, derivatives, non-U.S. securities, and indirect holdings through funds or private investment vehicles. Additionally, the reporting does not reflect portfolio intentions, hedging strategies, or recent purchases that had not yet been integrated at the time of filing. Thus, investors should interpret the figures as a snapshot, not an exhaustive description of the fund's current strategy.
