Ask what Korea is talking about.

South Korean stocks suffered a historic plunge on Nov. 5 as the US midterm 'blue wave'—Democrats taking control of Congress—sparked fears of tighter regulations on AI and large tech firms. The KOSPI and KOSDAQ both fell more than 5%, with Business Korea reporting the market 'failed to withstand the storm of concerns' over AI and tech regulations, while KBS World noted the plunge was 'rattled by concerns' of tighter rules. The Korea Times reported the 'blue wave' is expected to cool memory chip prices and demand, casting doubt on whether Samsung Electronics and SK hynix can sustain their performance. Korean media also highlighted Elon Musk as a major loser, with Texas flipping blue and Republicans suffering a landslide defeat, according to the Korea Times. The market reaction reflects Korean investors' anxiety over potential US regulatory shifts that could hit the country's key tech exporters.
