Why US stock market suddenly surging after big crash today: Dow Jones, S&P 500 and Nasdaq turn green after sharp sell-off on inflation and AI fears

US stock markets suddenly turned higher today after sharp early losses. The Dow Jones, S&P 500 and Nasdaq all moved from red to green. Traders cheered cooler-than-expected January inflation data, with the CPI rising just 0.2%, below forecasts. Treasury yields fell and risk appetite returned. Tech and growth stocks bounced back. Bitcoin and Ether also rallied. The market reversal reflects easing rate fears and renewed buying after heavy AI disruption selling.
