Berkshire Hathaway gains ground, but still trails the S&P 500 as '26 enters second half

As we move into the second half of 2026, Berkshire Hathaway's B shares have fallen 1.8% this year, lagging significantly behind the S&P 500's 10.7% increase. Despite recent gains, Warren Buffett's conglomerate still trails the broader market performance, raising questions about its investment strategy and valuation. This lag is notable given Berkshire's historically strong track record, suggesting a shift or potential challenges in the company's approach to market dynamics.
