The KOSPI surpassed the historic 3600 level for the first time after reopening a week following the Chuseok holiday, trading at 3600.80. The surge was primarily driven by strong semiconductor stocks, particularly significant gains in SK Hynix and Samsung Electronics. The positive momentum from the U.S. stock market during the holiday period is analyzed to have been reflected in the domestic market. Meanwhile, the KOSDAQ showed a declining trend, with clear divergence between individual buying and institutional and foreign selling.
