The KOSPI closed sharply higher on Wednesday, November 11, 2026, extending its rebound to a second session. The benchmark Korea Composite Stock Price Index gained 136.23 points, or 2.60%, to finish at 5,375.36, according to Yonhap News Agency. The index had risen 4.39% in the previous session.
Technology shares drive broad advance
The market opened 0.56% lower but reversed course during the session and reached an intraday high of 5,377.99. Foreign investors bought a net 655.26 billion Korean won in shares, while institutions and individuals were net sellers, according to Yonhap.
Large technology companies were among the strongest contributors. Samsung Electronics rose 3.57% to 206,000 Korean won, while SK hynix gained 5.36% to 1.277 million Korean won. Defense stocks also outperformed: Korea Aerospace Industries advanced 7.71% and LIG Defense & Aerospace climbed 9.73%. Hyundai Motor declined 0.91%, while Hanjin KAL fell 14.64%.
Oil prices support sentiment
Yonhap attributed the advance partly to lower oil prices after comments by US President Donald Trump reduced expectations of further military action against Iran. Hyundai Motor Securities also cited bargain hunting in artificial-intelligence-related shares as a market support. The gains came despite weaker overnight trading in the United States, where the Dow Jones Industrial Average fell 0.3% and the Nasdaq Composite declined 0.74%.
Inflation remains a policy risk
Investors continued to assess the implications of stronger US inflation. Consumer prices rose 0.3% month on month in October, exceeding market expectations and raising concerns that the Federal Reserve could maintain a more aggressive tightening stance. That risk limited the market's ability to treat the technology rebound as a straightforward change in the interest-rate outlook.
The KOSPI's latest advance therefore reflected a combination of sector rotation, bargain hunting and improved sentiment around energy prices rather than a single catalyst. The KOSPI topic page contains the preceding session's market coverage.
