Global shares mixed after US midterms as AI stocks slide

World shares were mostly higher Thursday following the U.S. midterm elections, but heavy selling of artificial intelligence-related stocks dragged down several Asian markets. South Korea's Kospi sank over 5 percent, while Japan's Nikkei 225 lost nearly 2 percent. The Democratic Party's loss of Congress control triggered a Wall Street rally Wednesday, with the Dow jumping over 3 percent, though AI-linked firms faced sharp declines. Samsung Electronics fell 7.6 percent, and Tokyo Electron skidded 9.5 percent, as investors weighed potential regulatory risks to the AI boom. European markets rose in early trading, with the German DAX up 0.6 percent and France's CAC 40 surging 1.2 percent. Oil prices were mixed after Brent crude plunged 8.7 percent Wednesday on hopes a Democratic-led Congress could pressure President Donald Trump to pull back from the Iran war.
