KOSPI Falls Back Below 7,000 as Chip Stocks Lead Selloff
South Korea's KOSPI index fell 2.7% to 6,889.74, dropping below 7,000, led by declines in Samsung Electronics and SK hynix, which each fell over 5%. Foreign and institutional investors sold heavily, while retail investors bought. The selloff was driven by rising U.S. Treasury yields and higher oil prices. Samsung Electronics closed at 270,000 won, and SK hynix at 1,768,000 won.
