Ask what Korea is talking about.

South Korean stocks plunged more than 5% on Thursday, Nov. 5, as concerns over tighter U.S. regulation of AI and data centers after a Democratic sweep in the midterms triggered a broad sell-off. Yonhap reports Seoul shares fell over 5%, with KOSPI closing at 5,383.8, down 300 points or 5.28%, while KOSDAQ lost 36.54 points, or over 5%. Business Korea and KBS World also reported the historic plunge, attributing it to the "Blue Wave shock." Korea Times notes the Democratic victory is expected to cool memory chip prices and demand, casting doubt on Samsung Electronics and SK hynix sustaining their performance, and that Elon Musk's business empire faces pressure as Texas flipped blue. Korean investors and analysts are reacting with alarm, viewing the regulatory fears as a major threat to the tech sector, though specific individual reactions are not detailed in the reports.
