AI Darlings at Record Highs – Why Wall Street Fears a Frothy Stock Bubble

Tech giants like Nvidia and Amazon, boosted by AI momentum, have driven most gains—Nvidia is up 55% this year, Palantir nearly 400%. Wall Street leaders warn valuations are stretched and a correction may be coming. Despite strong earnings, investor caution persists, with some stocks dropping after upbeat results.
