Berkshire Finally Topped Its Pre-Buffett-Exit Peak

Berkshire Hathaway’s Class B shares closed at a record $539.82 on Tuesday, Oct. 20, up 1.43%, topping the prior all-time high of $539.80 set May 2, 2025. The new record came after 17 months in which the S&P 500 rose more than 35% while Berkshire stayed below its previous peak. On Oct. 21, both share classes logged intraday highs, with Class B reaching $543.34 before closing at $538.99. The article links the move largely to money rotating out of AI stocks: SOXX fell 15.17% from Oct. 6 to Oct. 20 while Berkshire gained about 7%. It also notes Berkshire’s buybacks—$4.5 billion in Q2—and a rise in operating profit to $12.98 billion, alongside succession momentum after Warren Buffett shifted roles as chairman.
