Broadcom Plunges 13% on June 4, But S&P 500 and Dow Hit Records as AI Trading Shifts

According to Business Insider, on June 4, chipmaker Broadcom fell more than 13% after reporting weaker-than-expected AI demand, yet the U.S. stock market showed resilience. The S&P 500 and Dow Jones Industrial Average both hit record highs, with the Dow rising nearly 900 points, while the Nasdaq Composite stayed roughly flat. The Philadelphia Semiconductor Index declined only about 2% despite Broadcom's sharp drop.

Analysts attributed this divergence to three positive signals for long-term market strength: 363 S&P 500 stocks advanced on the day, indicating healthy market breadth beyond tech; investor reactions remained measured, suggesting traders view Broadcom's weakness as company-specific rather than an industry-wide demand warning; and the market appears to be transitioning from irrational herd trading toward rational differentiation between winners and losers.
