On November 14, 2025, Berkshire Hathaway disclosed a major new stake in Alphabet, acquiring 17.9 million shares valued at $4.3 billion, making it a top ten holding and the firm's largest new tech position since its initial Apple investment. The company also trimmed its Apple stake by 15%, selling 42 million shares, though Apple remains Berkshire's largest position. These portfolio changes were reported by CNBC and the Wall Street Journal, and are likely to have influenced investor sentiment and contributed to BRK-B's price decline to $508.94 (-0.81%) on November 14, 2025. No other company-specific news or earnings were reported after the market closed on November 14. The broader market saw modest losses and continued uncertainty following the end of the US government shutdown on November 13, but Berkshire's moves were the most notable driver for its stock.
