Berkshire Hathaway Places Huge Bets on Apple, Alphabet

Berkshire Hathaway's equity portfolio is heavily concentrated in just five stocks, with over 66% of its value resting on American Express, Apple, Bank of America, Alphabet, and Coca-Cola.

The company's US equity holdings total approximately $263 billion, making the concentration of funds in these five companies a significant concern for investors.

Apple remains the single largest position, representing roughly 22% of the portfolio at an estimated $58 billion as of March 31. American Express comes in second at about 17%, worth approximately $46 billion.

The concentration of funds is not new behavior for Berkshire Hathaway, with its portfolio historically holding between 66% and 71% of its value in the top five holdings across multiple quarters.
