AI stocks snap back: Nvidia surges, Dow clears 50,000 as Amazon’s AI spend spooks investors
New York, February 6, 2026, 17:05 EST — Trading after the bell. Nvidia and several other chipmakers connected to AI soared Friday, driving the Dow Jones Industrial Average past the 50,000 mark for the first time.
