Berkshire Hathaway (BRKA) Holds 60% of Portfolio in 5 Companies

Greg Abel, the current CEO of Berkshire Hathaway (NYSE: BRKA, NYSE: BRKB), has maintained 60% of the company's $359 billion stock portfolio in just five companies: Apple, American Express, Alphabet, Bank of America, and Coca-Cola. In the second quarter of 2026, Berkshire reduced its Bank of America stake by 5.9% while increasing its investment in Alphabet by 45.2%. Despite the high concentration in these stocks, Abel indicated that the portfolio will remain largely focused on these names, with potential adjustments if fundamental changes occur. For ordinary investors, this concentration could represent both stability and risk given the significant reliance on these key companies.
