Japan's Nikkei Falls 5.8% as AI Sell-Off Spreads From Wall Street to Asia

Japan's main stock index, the Nikkei 225, fell 5.8% on November 6, 2026. It dropped more than 6% soon after opening, per Bloomberg, and was set to be its biggest one-day loss since April 2025. It followed a U.S. sell-off led by AI stocks, the worst since 2020. Asian index funds, which hold baskets of shares heavy in tech, carry this exposure.
