The benchmark Korea Composite Stock Price Index (KOSPI) rose 141.58 points to 7,149.3 as of 9:15 a.m. local time. This follows a record close for the tech-heavy Nasdaq Composite, driven by renewed optimism for artificial intelligence, and a fall in global oil prices and bond yields. On Monday, US stocks rallied, with the Nasdaq Composite rising 2.3 percent and the S&P 500 gaining 1.5 percent.
