Berkshire Hathaway shares climbed to a new 52-week high after second-quarter results showed operating earnings rose 16% year over year and net earnings more than doubled, while Rep. Maria Elvira Salazar disclosed fresh July purchases of the conglomerate's Class B shares. BRK.B reached $537.74 on Monday, its highest level since Warren Buffett stepped down as CEO and was replaced by Greg Abel, leaving the stock just below its all-time high of $542.07 set on May 2, 2025. Salazar reported two July 28 Berkshire purchases, one for $1,000 to $15,000 and another for $15,000 to $50,000, alongside same-day sales of Carrier and earlier July purchases of Chubb. Berkshire's results and capital deployment also kept attention on a 13F filing due Friday that may reveal additional investments.
