description: "The Democratic Party's comprehensive victory in the US midterm elections triggered a wave of AI sell-offs. The semiconductor index fell 12%, marking its worst single-day performance since March 2020, while the Nasdaq 100 dropped 6.4%.Investors now view the new Congress and key states as brakes on AI expansion. Texas's newly elected governor called for a pause on new data center construction. S&P 500 -4.36%, Nasdaq -5.52%, Dow Jones -3.44%; VIX panic index surged to 28.US tech companies remain relatively stable, but stocks in data centers and energy-intensive AI infrastructure sectors plummeted.Particular attention should be paid to the Wall Street sell-off triggered by the surge in the panic index."
