Berkshire Hathaway: Warren Buffett's Investment Philosophy

Warren Buffett has built his reputation on an investment approach focused on long-term value. He prioritizes businesses with sustainable competitive advantages, stable cash flow generation, and capable management. The fund avoids speculative strategies and focuses on holding common stocks, which is reflected in the composition of the 13F filing where only long positions are visible. Historically, Berkshire's performance has outpaced the S&P 500 over several decades due to rigorous stock selection and patient capital management.

Major New Positions and Strengthenings

According to available information, the third-quarter 2026 filing does not indicate any new positions or major strengthening compared to previous filings. The portfolio remains dominated by the ten major stocks listed, collectively representing 92.5% of the total reported value.

The major holdings are distributed as follows: Apple Inc. ($65.95 billion, 22.0% of the portfolio) illustrates Buffett's preference for high-margin brands with loyal customer bases. American Express ($51.28 billion, 17.1%) reflects interest in financial services companies benefiting from a widely established payment network. Alphabet Inc. ($37.76 billion, 12.6%) indicates exposure to tech giants with strong data monetization capabilities. Coca-Cola ($32.51 billion, 10.9%) confirms confidence in durable consumer brands with predictable cash flow. Bank of America ($27.54 billion, 9.2%) reflects exposure to major U.S. banks offering attractive dividend yields.

The remaining positions include: Chevron ($13.99 billion, 4.7%) and Occidental Petroleum ($12.87 billion, 4.3%) provide exposure to hydrocarbons, a sector Buffett views as essential to the global economy despite the energy transition. Chubb Limited ($11.67 billion, 3.9%) represents the insurance sector, known for revenue stability. Moody's Corp. ($11.17 billion, 3.7%) offers exposure to financial rating services, a field characterized by high reputation and entry barriers. Finally, Kraft Heinz ($7.69 billion, 2.6%) shows interest in strong consumer food brands with robust margins.

In the absence of new acquisitions, the portfolio's stability indicates that Berkshire's investment committee continues to affirm its confidence in the quality of these companies. No quantitative strengthening is indicated in the filing, but the high concentration around these stocks suggests that the fund maintains its positions at levels deemed appropriate by management.

Reductions and Exits – What Buffett is Leaving Behind

The 13F report mentions no reductions or full exits among the 26 holdings. Without additional data, it's impossible to identify divestments during the quarter.

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

Required by the SEC, the 13F form only lists long positions in U.S. stocks and certificates of deposit backed by stocks, with a 45-day lag after the quarter's end. It does not reveal short positions, options, futures contracts, or foreign investments. Additionally, the reported value corresponds to market value on the last day of the quarter, without considering intramonthly fluctuations. Thus, the filing provides only a partial view of Berkshire's global strategy.

For individual investors, it's important to understand that the 13F does not show unlisted assets, private stakes, bonds, or derivatives that may represent a significant portion of Berkshire's total capital. Similarly, allocation decisions between stocks are only visible when they result in a threshold change of 5% of the portfolio or when a new position exceeds the SEC's 10,000-share threshold.

In conclusion, the declared portfolio of Berkshire Hathaway for the third quarter of 2026 confirms the persistence of Buffett's strategy, centered on high-quality and large-cap stocks. The major positions remain Apple (22% of the portfolio), American Express (17%), Alphabet (13%), Coca-Cola (11%), and Bank of America (9%).
