Berkshire Hathaway shares hit record highs this week, capping a fourth-quarter surge. Class A shares closed at fresh records 11 times since October 1 and gained 19.1% during that period. Class B shares, which are more widely held, notched 10 new record closes and also rose 19.1% from their near-term low.
The rally stands apart from the broader market. The S&P 500 fell 1.2% over the same stretch. Investors appear to view Berkshire as a relatively safe haven amid concerns about AI stocks and spending.
