The South Korean stock market has experienced a sharp downturn, with the KOSPI index plummeting over 5% as concerns about the semiconductor industry intensify. Major tech companies such as Samsung Electronics and SK Hynix have seen their shares tumble more than 7%, mirroring trends observed on Wall Street. This decline in tech stocks has led to volatility in the market, prompting a trading halt due to the drastic fall. Investors are currently weighing the effects of AI capacity uncertainties alongside upcoming U.S. jobs data, contributing to a broader decline across Asian markets. As fears surrounding the chip sector grow, South Korean shares have slid to a three-week low, with analysts noting a significant sell-off by foreign investors.
