Tech rebound lifts Nasdaq 1.7%; Nvidia forecasts AI chip sales acceleration

US tech stocks rebounded sharply on Thursday, with the Nasdaq up 1.7% and the S&P 500 reclaiming 7700, as the recent AI-related correction proved short-lived. Nvidia's CEO Jensen Huang projected a significant acceleration in AI chip sales next year, providing a key catalyst. The move signals renewed risk appetite in tech, though sustainability depends on broader macro data.
