The benchmark KOSPI rose more than 3% to around 5,995 on Tuesday, rebounding sharply to its highest level since late February, amid renewed US–Iran talks hopes and strength in technology and AI-related stocks. Investor sentiment improved after both the US and Iran showed openness to re-engage despite the recent breakdown in talks and continued military tensions, easing fears of a prolonged disruption in global energy supply. Oil prices pulled back from recent highs, relieving inflation concerns and supporting the outlook for energy-importing economies such as South Korea. At the same time, gains tracked a broader rally in global equities after Wall Street advanced to fresh highs, with technology and AI-related shares leading the rise. Notable gains were seen in Samsung Electronics (3.3%) and SK hynix (7.0%), alongside Hyundai Motor (4.4%), SK Square (7.1%), Kia Corporation (2.2%), and HD Hyundai Heavy Industries (1.6%).
