The benchmark KOSPI fell 1.0% to around 3,190 on Monday, extending losses as investors returned from a holiday to track weakness in major technology shares as Seoul caught up with Wall Street’s soft close on Friday. Domestically, chipmakers led the downturn, with Samsung Electronics falling 1.8% and SK Hynix slipping 2.4%, while LG Energy Solution tumbled 1.8%. Defense and industrial stocks also joined the selloff, with Hanwha Aerospace down 0.3%. On the external front, sentiment was dampened by geopolitical tensions after the US–Russia summit ended without movement toward a ceasefire. The outcome signaled little progress toward de-escalation, keeping investors cautious amid concerns of prolonged instability in Eastern Europe and fueling risk aversion across Asian markets. Meanwhile, concerns lingered over stretched tech valuations and uncertainty around the US monetary policy, with investors awaiting signals from the Jackson Hole symposium later this week.
