Berkshire Hathaway (BRK.B) (BRK.A), the storied conglomerate synonymous with investment legend Warren Buffett, has seen its stock price tumble more than 10% since Buffett announced his retirement as CEO at the company’s annual shareholder meeting in early May 2025. The decline marks a significant shift for the company, which has long enjoyed a “Buffett premium” — a valuation boost attributed to investor confidence in Buffett’s stewardship.
