The benchmark KOSPI climbed 3.75% to around 5,206 on Tuesday, recouping recent losses as a rally in US technology stocks and easing geopolitical tensions in the Middle East improved investor sentiment. The advance tracked overnight gains on Wall Street after US President Donald Trump signaled reluctance to resume strikes against Iran, bolstering hopes for diplomatic engagement and pushing oil prices lower, which in turn helped temper inflation concerns.
Robust buying in technology names underpinned the rebound, led by Samsung Electronics (+5.32%) and SK Hynix (+7.22%). Other notable gainers included LG Energy Solution (+4.25%), Hyundai Motor (+2.58%), and KB Financial (+3.51%).
In derivatives trading, the Korea Exchange (KRX) triggered a buy-side sidecar at 9:06 am, temporarily halting program trading in KOSPI-listed stocks for five minutes after the KOSPI 200 futures index rose by at least 5% for one minute.
