The benchmark index retreated sharply from its all-time peak, reversing gains driven by tech and semiconductor stocks.
South Korea’s KOSPI index fell 8.4% from its record high of 8,046.78, wiping out ₩509 trillion in market value. The decline followed a surge fueled by AI-related technology and semiconductor stocks, which led the earlier rally.
The index had reached its all-time peak on Friday, supported by strong demand in the tech sector. However, the advance reversed amid profit-taking and broader market volatility, erasing gains accumulated during the week.
No immediate market reaction details were provided, but the sharp pullback highlights fragility in the recent tech-driven rally.
