South Korean stocks rebound as chip shares surge
South Korea’s KOSPI and KOSDAQ surged in Seoul on November 10, after three days of declines.
The rebound came as Samsung Electronics and SK Hynix led gains among major chipmakers.
US stocks and semiconductor shares had risen sharply overnight, helped by investors buying technology stocks after recent falls.
Earlier worries about possible delays to data-centre projects had added pressure to South Korean shares.
The sharp move triggered temporary buying curbs on both markets, designed to limit volatility from program trading.
Investors are watching for US inflation data and CoreWeave results, which could influence whether the rebound continues.
