Warren Buffett will turn 96 on Sunday and remains actively involved as Berkshire Hathaway's chairman after stepping down as CEO. The company has accumulated a $36.6 billion stake in Alphabet, Google's parent, in recent quarters, but Berkshire's Class B shares have underperformed. After reaching an intraday high of $537.74 on Aug. 10 following the second-quarter earnings report, the shares closed Friday at $505, up 0.5% year to date. The performance trails the S&P 500's 12.7% gain by 12.2 percentage points. Barron's cited several possible reasons for the lag, including uncertainty around Greg Abel as CEO, investor disappointment that Berkshire has not reduced its cash more aggressively, its continued refusal to pay a dividend and the lack of a $100 billion-plus acquisition. Berkshire also appeared in five of the 1,051 trades listed in President Donald Trump's June disclosure to the U.S. Office of Government Ethics. The filing recorded three purchases and two sales, with four transactions identifying Class B shares; because only value ranges were disclosed, Trump was a net buyer after a June 18 purchase of between $1 million and $5 million. His 2025 annual report listed Berkshire holdings in the same range. Bloomberg said earlier reviews of Trump's trading showed patterns consistent with overlapping, often index-based and probably automated portfolio strategies. The Trump Organization has said third-party financial institutions manage the trades independently through automated, model-based portfolios and direct indexing strategies, without input from Trump or his family. Buffett has also argued that the United States should trade with the rest of the world and said trade should not be used as a weapon. Berkshire reported $365.5 billion in cash as of June 30, down 8.0% from March 31, or $359.2 billion excluding railroad cash and subtracting Treasury bills payable, down 3.8%. The company repurchased $4.5 billion of its shares in the second quarter of 2026. Its market capitalization was $1,081,295,529,555, with a Class A price of $757,985.01, a Class B price of $505.00 and a Class B trailing P/E of 12.70. Public-stock holdings are valued using the latest closing prices, with holdings dated June 30, 2026, based on Berkshire's 13F filing submitted Aug. 14, 2026, subject to exceptions not specified in the newsletter.
