The KOSPI surged to the 3,560 level ahead of the extended holiday, marking a record high. The main drivers were easing concerns over a U.S. federal government shutdown and strong performance from large semiconductor stocks. Samsung Electronics touched the 90,000-won level, setting a new all-time high, while SK Hynix broke through the 400,000-won mark for the first time. Foreign investors had a significant impact on the index surge, with net purchases exceeding 1 trillion won in both the KOSPI and KOSPI 200 futures market. KOSDAQ also continued its upward trend, trading at 852.23.
