ёThe benchmark KOSPI fell 0.8% to around 4,845 on Wednesday, extending losses for a second straight session as lingering uncertainty over US tariffs weighed on broader sentiment. Exporters remained cautious after the US Supreme Court again withheld a ruling on the legality of “reciprocal” tariffs, leaving potential duties on Korean goods unresolved. Combined with ongoing foreign selling, this uncertainty fueled selective profit-taking and dampened participation outside technology. The decline was led by LG Energy Solution (-2.2%), Hanwha Aerospace (-1.3%), HD Hyundai Heavy Industries (-2.2%), and Doosan Enerbility (-3.7%). Meanwhile, semiconductor leaders Samsung Electronics (+2.6%) and SK Hynix (+0.4%) stayed resilient on expectations of a sustained chip upcycle driven by AI demand, alongside advances in Hyundai Motor (+8.8%) and Kia Corporation (+3.7%).
