On the 5th (local time), the Dow Jones Industrial Average closed at 51,523.06 on the New York Stock Exchange (NYSE), down 3.44% from the previous trading day. The S&P 500 Index plummeted 4.36% to 7,353.73, while the tech-heavy Nasdaq Composite Index plunged 5.52% to 24,315.00. The market’s volatility index (VIX) surged 69% in a single day, clearly reflecting the panic sentiment across the market.
The market decline was led by key stocks in the AI infrastructure value chain.

The Philadelphia Semiconductor Index plummeted by more than 12%. As a result, major domestic semiconductor stocks are also expected to be affected.
