The benchmark KOSPI rose 0.70% to around 3,775 on Monday, rebounding from the previous session’s flat performance amid recent Wall Street gains and optimism over “substantive progress” in US–Korea trade talks. The upbeat sentiment followed remarks by presidential policy chief Kim Yong-beom, who stated that most issues had been resolved during recent follow-up tariff discussions with US officials in Washington. Speaking on Sunday, Kim noted that only one or two matters still require coordination but described the talks as constructive, expressing optimism that an agreement could be reached before the APEC summit in South Korea later this month. Across sectors, shipbuilding and biopharmaceutical stocks led the advance, with notable gains in Hanwha Ocean (5.88%), HD Hyundai Heavy Industries (1.18%), HD Korea Shipbuilding (1.19%), Samsung Biologics (2.15%), and Alteogen (1.96%). Meanwhile, LG Energy Solution (-1.04%) and Samsung Electronics (-0.61%) posted losses.
