Wall St ends lower as AI fervor wanes after Nvidia results

Wall Street concluded lower as investor enthusiasm for artificial intelligence stocks cooled following Nvidia's latest earnings report. While Nvidia's results were strong, the market interpreted them as potentially indicating a peak in AI-driven growth or a recalibration of extremely high valuations. This waning fervor suggests a potential shift towards broader market factors or a more selective approach to tech investments, impacting indices like the Nasdaq significantly.
