The KOSPI closed sharply higher on Wednesday, November 11, 2026, recovering after a weak start as semiconductor stocks and foreign buying lifted South Korean equities. The benchmark Korea Composite Stock Price Index ended at 5,375.36, up 136.23 points, or 2.60 percent, from the previous trading session.
According to Yonhap News Agency, the index opened 0.56 percent lower and later reached an intraday high of 5,377.99. The move extended the KOSPI's recovery to a second session after Tuesday's 4.39 percent rise.
Foreign buying supports large caps
Foreign investors were net buyers of KRW 655.26 billion in KOSPI shares, while institutions and individuals were net sellers, according to Yonhap. The buying was concentrated in large technology companies. Samsung Electronics rose 3.57 percent to KRW 206,000, while SK hynix gained 5.36 percent to KRW 1,277,000.
Korea JoongAng Daily reported that gainers outnumbered decliners 573 to 295. Defense stocks also advanced, while selected automakers and other shares fell, indicating that the session's strength was concentrated in technology and related growth themes rather than fully broad-based.
AI optimism meets rate concerns
Market sentiment improved around artificial-intelligence investment after strong results from US AI cloud company CoreWeave and reports that Anthropic was considering a higher IPO price ahead of its planned Nasdaq listing. The Asia Business Daily cited KB Securities analyst Lim Jungeun, who said that improved sentiment toward AI investment helped South Korean shares despite inflation concerns and that semiconductors led the gains.
At the same time, hotter-than-expected US consumer-price data kept the risk of more aggressive Federal Reserve tightening in focus. The market therefore balanced renewed demand for AI infrastructure with the possibility that higher interest rates could weigh on technology valuations. Investors were also looking ahead to South Korea's domestic options expiration on November 12, which could contribute to near-term volatility.
