- The KOSPI closed at 5,239.13 on November 10, gaining 4.39 percent from the previous session.
- Technology shares led the rebound as U.S. semiconductor stocks rallied and oil prices fell on hopes of easing Middle East tensions.
- Foreign investors returned as net buyers, while the index pared part of an intraday advance above 5,300.
- The strong session followed three consecutive declines, leaving the durability of the rebound dependent on semiconductor and data-center investment expectations.
The KOSPI staged a broad rebound on Tuesday, November 10, as stronger U.S. technology shares and a sharp decline in oil prices improved risk appetite. The benchmark Korea Composite Stock Price Index closed at 5,239.13, up 220.28 points, or 4.39 percent, from the previous session's close of 5,018.85. The close was below the day's high of 5,300.92.
Technology shares lead the rebound
According to Yonhap News Agency, the Korea Exchange activated a buy-side sidecar at 9:06 a.m. after the market opened 4.55 percent higher. Technology shares were central to the advance: Samsung Electronics rose 4.74 percent and SK hynix gained 6.69 percent. Samsung Electro-Mechanics advanced 4.63 percent, while SK Square, the parent of SK hynix, climbed 5.26 percent.
Yonhap attributed the rally to gains on Wall Street, including a 6.85 percent increase in the PHLX semiconductor index, and to lower oil prices after comments by U.S. President Donald Trump reduced expectations of an immediate resumption of military strikes against Iran. Airline shares also benefited from the lower oil-price backdrop. The Korean won strengthened to 1,337.5 against the U.S. dollar at 3:30 p.m. Seoul time, according to the report.
Foreign investors return, risks remain
Foreign investors bought a net 365.9 billion won in Korean equities, while institutions purchased a net 489 billion won. Individuals were net sellers of 1.3 trillion won. Advancing shares outnumbered decliners 714 to 174, pointing to a market-wide recovery rather than a move confined to a few large companies.
The Seoul Economic Daily reported that the index gave back part of its advance after crossing 5,300 and noted that foreign buying returned after heavy selling in recent sessions. The rebound therefore restored part of the losses but did not by itself resolve concerns about semiconductor supply, the pace of artificial-intelligence data-center investment and the sustainability of technology demand.
