The KOSPI opened lower for the week. This is interpreted as the continued impact of the sharp drop in AI and semiconductor stocks in the U.S. stock market over the weekend, driven by instability in the AI industry.

As of 9:12 a.m. on Monday, the KOSPI stood at 5,601.20, down 66.85 points (1.18%) from the previous trading day. The index had opened at 5,488.41, a drop of 179.64 points (3.17%), but narrowed its decline as bargain-hunting buying by foreign investors and institutional investors flowed in.

Han Ji-young, a researcher at Kiwoom Securities, explained, "Following the sharp drop in U.S. AI stocks on Friday (local time), domestic stock markets are also expected to face downward pressure. The strength of any subsequent rebound and whether support can be secured will likely depend on the outcomes of major domestic and international events." She added, "While most key sectors, including semiconductors and IT hardware, remain in an oversold phase based on stock prices, making this a zone with high incentives for bargain hunting, AI industry instability persists due to credit risks, investment cuts, and weakening earnings momentum. Therefore, investors should prepare for volatility for the time being."
