[Edaily Reporter kyoungeun kim ] On the morning of the 10th, the KOSPI opened with a sharp rise of over 3%, buoyed by the strong performance of the New York stock market overnight. News that the Chinese government is moving to allow the purchase of NVIDIA’s artificial intelligence (AI) semiconductors has driven buying across the AI semiconductor sector, pushing the Philadelphia Semiconductor Index (SOX) up by over 3%. Meanwhile, the listing of SK hynix(000660)’s American Depositary Receipts (ADRs) is considered the biggest variable of the day.
According to MP Doctor, as of 9:04 a.m., the KOSPI is trading at 7,562.96, up 271.05 points (3.72%) from the previous trading day.

Earlier on the 9th (local time), the New York Stock Exchange closed higher as expectations for a return to U.S.-Iran negotiations following mediation attempts by Qatar and Pakistan, news of Micron’s additional $250 billion investment in the U.S., and Meta’s announcement of expanded production and investment in its own AI chips all converged.
The Standard & Poor’s (S&P) 500 Index closed at 7,543.64, up 0.81% from the previous trading day, the Nasdaq rose 1.3% to 26,206.89, and the Dow Jones Industrial Average climbed 0.27% to 52,487.41. The SOX index rose 3.06%, while Micron surged 4.52% and SanDisk jumped 7.6%.
Han Ji-young, an analyst at KIWOOM Securities, said, “While concerns over U.S.-Iran negotiations remain merely noise-like factors that only trigger short-term uncertainty, the factors that had caused stock market volatility—such as the recovery of AI investment expectations and the limited rise in interest rates—are easing.” She added, “Today’s listing of SK hynix ADRs could serve as a catalyst to improve investment sentiment across the KOSPI, including the semiconductor sector.”
