The latest disclosed data shows that Berkshire Hathaway, led by Warren Buffett, demonstrates a distinctly concentrated investment strategy.

As of March 31, 61% of the total fair value of its equity investment portfolio was highly concentrated in five well-known companies: American Express, Apple, Bank of America, Chevron, and Coca-Cola. This configuration highlights Berkshire Hathaway's firm confidence in its core holdings. The five major stocks hold an absolutely dominant position in the investment portfolio, reflecting management's deep recognition of these companies' long-term value and profitability. Such a high degree of concentration not only exemplifies Buffett's classic investment philosophy—allocating a significant amount of capital to the most trusted targets—but also indicates that its performance will be closely linked to the development of these industry leaders.The concentration characteristic of the portfolio is particularly striking in the current market environment. In a market with heightened volatility, Berkshire Hathaway still maintains an overweight position in its core assets, remaining consistent with its value investment philosophy of being "greedy when others are fearful." The five major holdings span financial technology, consumer electronics, banking, energy, and beverage industries, demonstrating a high-quality cross-industry asset allocation pattern.
