The KOSPI fell 129.12 points to 5,605.54 as of 11:20 a.m. The index opened 1.14% lower and extended its losses amid apparent profit-taking.

The decline in Seoul came after U.S. stocks closed mixed overnight, with AI-related shares rebounding following SpaceX's quarterly results. The Dow Jones Industrial Average rose 0.69%, the S&P 500 gained 0.58% and the tech-heavy Nasdaq Composite advanced 1.05%. Meta Platforms boosted its bet on the AI sector after delivering sound earnings, according to the report.

In Seoul, technology stocks led the market lower. Samsung Electronics fell 3.36% and SK hynix lost 3.63%. Samsung Electro-Mechanics Co., an electronics components affiliate of Samsung Electronics, edged down 0.98% after opening higher on news of cooperation with Nvidia.

The Korean won was trading at 1,324 won against the U.S. dollar as of 11:20 a.m., up 2 won from the previous session's close, Yonhap reported.
