US stock markets experienced a sharp reversal on Thursday, erasing gains from the Nvidia-led AI rally. Concerns over AI stock valuations, fading hopes for Federal Reserve interest rate cuts after a strong jobs report, and cautious statements from market veterans weighed down sentiment. Nvidia shares fell significantly from day's highs, while Walmart Inc. stood out with a substantial gain after beating third-quarter expectations and raising its full-year guidance.
