South Korea's KOSPI Triggers Circuit Breaker After 8% Plunge
South Korea's benchmark KOSPI index crashed more than 8% shortly after Monday's opening bell, triggering a 20-minute circuit breaker. The sell-off was led by semiconductor heavyweights Samsung Electronics and SK Hynix, both of which plunged approximately 10% as foreign investors dumped technology stocks. The rout mirrors a sharp decline in U.S. AI-linked shares, including Nvidia and Micron, from the previous Friday. While some reports attribute the volatility to profit-taking and a rotation out of chip stocks, other sources cite broader pressures including inflation concerns, rising interest rates, and geopolitical tensions involving the U.S. and Iran.
