KOSPI Plunges Nearly 7 Percent Below 5,950 as Foreign Selling Hits Samsung and SK Hynix
South Korea's KOSPI index dropped nearly 7% to 5,940.48 by late morning, driven by foreign selling in chip stocks. Samsung Electronics fell 7.3% and SK Hynix 8.4%. The decline followed remarks from a Chinese memory maker about new technology. Foreign investors sold 2.3 trillion won ($1.7 billion) by 11:20 a.m.
