Nvidia’s share price has slumped to its lowest since 2019, bringing its market value below $1 trillion for the first time in recent months. The stock now trades at valuations previously observed before the artificial intelligence sector’s swift growth.

The decline reflects investor caution even as demand for AI chips remains strong.
