AI overview

The S&P 500 fell 3.8% during Thursday's intraday trading, led lower by chip stocks as the Philadelphia Semiconductor Index dropped 10.2%. The index neared the 7% decline that triggers a 15-minute U.S. market-wide trading halt, leaving roughly 3.3 percentage points before a pause would be triggered. The halt level was set at 7,150.41, calculated from Wednesday's close of 7,688.62. Reports attributed the volatility to investor concerns that Democratic gains in Congress could slow demand for data center and AI chips.
