Why Asian AI stocks tumbled after US midterm results as Kospi plunged over 5%; key reasons explained

Asian AI and semiconductor stocks sold off sharply after the US midterm elections, with South Korea's Kospi plunging 5.3% to 5,383.80 and triggering a temporary halt to program trading. Taiwan's Taiex fell 1.8%, Japan's Nikkei 225 declined 2%, and Brent crude dropped 8.7% to $94.62 as investors anticipated tighter US restrictions on AI data centres and less military support for the Iran conflict.
