Key Facts
South Korea’s KOSPI closed 11 November up 136.23 points, or 2.60%, at 5,375.36, according to the Korea JoongAng Daily. The advance came as foreign investors returned to buying, alongside gains in semiconductor shares. Foreign investors were net buyers of 655.26 billion won during the session. Institutional and retail investors, by contrast, were net sellers of 481.67 billion won and 715.69 billion won, respectively. The flows highlight diverging positions among investor groups in a session when the index rose despite domestic selling pressure.
The index opened down 0.56%, then reversed course and climbed to an intraday high of 5,377.99 points before closing near that level at 5,375.36, the newspaper reported. The session’s trading showed a shift from a lower open to broad gains as trading progressed. The report described the close as a rise of 136.23 points, equivalent to 2.60% from the previous session. Chip stocks led part of the turnaround, with Samsung Electronics up 3.57% at 206,000 won. SK hynix rose 5.36% to 1.28 million won, outperforming Samsung in percentage terms.
The Korean currency also strengthened, gaining 3.9 won against the dollar from the previous session to trade at 1,333.6 won per dollar at 3:30 p.m., according to the Korea JoongAng Daily. The won’s improvement coincided with gains in South Korean shares in the same session. In the preceding session, the KOSPI had risen 4.39% on Tuesday, 10 November. The newspaper linked that session’s gains to a rally in U.S. technology shares and lower oil prices. This places the 11 November session in the context of two consecutive days of index gains, with coverage describing different drivers for each session.
Behind the gains in chipmakers, CoreWeave reported revenue of $3.7 billion in the third quarter of 2026, up 168% year on year and $1 billion from the previous quarter, according to the company’s investor relations data. Adjusted operating income was $379 million, with a 10% margin. On 10 November, the company raised its full-year revenue forecast to a range of $13.0 billion to $13.3 billion. It also raised its year-end annualized run-rate revenue forecast to a range of $20 billion to $21 billion. A Korean report described the results and forecasts as a factor that helped ease concerns about continued spending on AI, without establishing them as the direct cause of the South Korean market’s rise.
