South Korea’s KOSPI opened 136.08 points, or 1.94%, higher at 7,153.99 on Sept. 23, led by technology heavyweights and gains in AI-related stocks. The advance followed two consecutive record closes for the tech-heavy Nasdaq Composite and came as diplomatic efforts to ease Middle East tensions helped push oil prices lower. U.S. stocks finished mixed on Tuesday, with the Nasdaq rising 0.45%, the Dow Jones Industrial Average falling 0.36% and the S&P 500 declining 0.06%. An earlier report had put the KOSPI’s opening gain at 1.73%, or 121.17 points, at 7,139.08, alongside premarket gains in Samsung Electronics and SK hynix before the Chuseok holiday.
