The benchmark KOSPI rose 1% to around 8,170 on Monday, extending gains from the previous session as technology stocks advanced ahead of key corporate earnings.
Investors looked ahead to Samsung Electronics' highly anticipated second-quarter results, which are expected to provide fresh confirmation of robust AI-driven memory chip demand and pricing following recent volatility in global semiconductor shares.
US stock futures also advanced despite lingering concerns over AI-related valuations, improving global risk sentiment.
Samsung Electronics climbed 3.4%, while SK hynix rose 1.3%.
Other notable gainers included SK Square (3.3%), Hyundai Motor (2.4%), HD Hyundai Heavy Industries (2.4%), Kia Corporation (5.5%), and KB Financial Group (2.1%).
Sentiment also remained underpinned by the government's continued support for AI and semiconductor development, including plans to launch a future-growth fund financed by semiconductor tax revenue and accelerate AI adoption across the economy.
