South Korea's benchmark KOSPI index dropped 7.82% on Thursday to close near 5,539, marking its lowest level since late July. The decline extended the index's losing streak to seven consecutive trading sessions. Foreign investors continued to sell off shares, and the rapid downturn forced a temporary halt on sell-side trading.

Major technology and manufacturing stocks led the slide. Shares of SK hynix dropped 11%, Samsung Electro-Mechanics sank 14.6%, and SK Square tumbled 10.1%. Semiconductor giant Samsung Electronics slipped nearly 9%. The sharp losses followed a broader slump among U.S. chipmakers as market participants questioned whether heavy spending on artificial intelligence remains sustainable. Outside technology, LG Energy Solution, Hyundai Motor, Doosan Enerbility, Hanwha Aerospace, and Kia Corporation also suffered notable losses.

Beyond valuation concerns in the technology sector, macroeconomic pressures continue to weigh on investor sentiment. Higher-than-anticipated U.S. inflation data, which showed annual CPI reaching 3.7% in September, sparked renewed fears of additional Federal Reserve interest rate increases. Investors will be keeping a close eye on global central bank policies, upcoming inflation figures, and tech earnings to evaluate borrowing costs and the outlook for equity markets.
