Korea Stock Market (KRX) Today: South Korea’s stock market rebounded on Thursday, September 3, after the KOSPI suffered a nearly 4% sell-off in the previous session. The benchmark index opened 1.33% higher and recovered above 6,600 as easing oil prices, firmer Wall Street trading and a rebound in semiconductor stocks improved investor sentiment.
Samsung Electronics and SK Hynix led the recovery, while investors also responded to reduced concerns about an immediate escalation in the Middle East. However, foreign and institutional selling limited the broader advance, keeping the market volatile.
Korea Stock Market (KRX) Today (September 3): Why is the Korean Stock Market Up Today?
The KOSPI bounced back after plunging 3.99% on Wednesday. The recovery followed gains on Wall Street, with the Dow Jones rising 0.56% and the Nasdaq gaining 0.45% overnight.
Easing crude oil prices also supported the rebound. US President Donald Trump’s comments suggesting that renewed US attacks on Iran could be short-lived helped reduce some concerns about a prolonged conflict and its potential impact on inflation.
Semiconductor stocks provided another major boost. Samsung Electronics and SK Hynix moved higher as US chip stocks strengthened, while investors also reacted to improving sentiment around AI-server demand.

Korea Stock Market (KRX) Today (September 3): What Should Investors Know?
The KOSPI’s rebound comes after one of its sharpest recent declines. The index fell 3.99% on Wednesday as higher oil prices, rising US Treasury yields and concerns about Middle East tensions increased pressure on Korean equities.
Thursday’s recovery suggests investors have returned to semiconductor stocks after the previous session’s heavy selling. Samsung Electronics and SK Hynix both moved higher as global chip sentiment improved.
However, investors should continue watching oil prices, US Treasury yields, Federal Reserve rate expectations, Middle East developments and foreign fund flows. The sharp swings seen over the past few sessions show that sentiment remains fragile even as the KOSPI attempts to recover.
