The KOSPI dropped 1.74% on the first day of short-selling resumption, breaking below the 2,500 mark for the first time in two months. U.S. tariff concerns and anxiety over short-selling were major factors driving the index decline. Secondary battery-related stocks, which saw a sharp increase in margin balances, fell significantly, while large-cap stocks such as Samsung Electronics and SK Hynix also showed weakness. KOSDAQ declined 1.49%, reflecting investor anxiety over the resumption of short-selling.
