South Korea's KOSPI ended Tuesday's session at 5,239.13, up 220.28 points, or 4.39 percent, from the previous trading session. The benchmark recovered after three consecutive declines, but remained in a volatile market environment following last week's technology-led sell-off. The closing level and session move were reported by Korea JoongAng Daily on November 10.
Technology stocks lead the rebound
The index opened 4.55 percent higher and reached an intraday high of 5,300.92. According to the Korea JoongAng Daily, the Korea Exchange activated a buy-side sidecar at 9:06 a.m., temporarily suspending program trading in KOSPI-listed shares for five minutes. The report said Samsung Electronics gained 4.74 percent to 198,000 won, while SK hynix rose 6.69 percent to 1.2 million won. Samsung Electro-Mechanics advanced 4.63 percent to 882,000 won.
The broader market also participated in the recovery. The source reported 714 advancing stocks against 174 decliners, with trading volume of 241 million shares and turnover of 16.2 trillion won. Foreign investors bought a net 365.9 billion won, and institutions bought a net 489 billion won. Individuals were net sellers of 1.3 trillion won.
Oil prices ease geopolitical pressure
Market sentiment was also supported by a sharp decline in oil prices after U.S. President Donald Trump said he was not prepared to resume military strikes against Iran, according to the Korea JoongAng Daily. Lower crude prices reduced immediate inflation concerns and helped lift risk appetite. Reuters separately reported that investors were watching developments around possible talks between the United States and Iran, while also awaiting U.S. inflation data that could influence expectations for the Federal Reserve's next interest-rate decision. Reuters noted that Brent crude was down 1 percent at 91.56 U.S. dollars per barrel in its market report.
The rebound was therefore concentrated in the same technology and growth-sensitive areas that had driven the preceding decline. A single strong session does not by itself establish a durable change in the KOSPI trend; investors will continue to weigh semiconductor momentum, oil-market developments and the path of U.S. interest rates.
