KOSPI tumbles

A financial data screen in the dealing room of Hana Bank in Seoul on Nov. 21, 2025, shows the benchmark Korea Composite Stock Price Index having declined 151.59 points, or 3.79 percent, to close at 3,853.26. South Korean stocks closed sharply lower, as renewed concerns over an artificial intelligence bubble weighed heavily on big-cap tech shares. (Yonhap)
