South Korea's Kospi dives more than 5%, SK hynix down 10%

South Korea's Kospi composite index fell more than 5% on Monday, its biggest single-day drop in months, as SK hynix slumped 10%. The sell-off in Seoul tracked a global rout in technology stocks, with chipmakers hit hardest. Traders cited concerns over export restrictions and slowing demand for memory chips. SK hynix, the world's second-largest memory chipmaker, led the decline among Kospi components. Samsung Electronics also dropped, though by a smaller margin. The broader index closed at its lowest level since early this year, extending losses from the previous session. The move came after U.S. semiconductor stocks tumbled on Friday, with the Philadelphia Semiconductor Index falling 4%. Asian markets followed suit, with Japan's Nikkei 225 losing 3% and Taiwan's Taiex sliding 4%.
