Nvidia's stock surges higher after earnings

Nvidia's market cap rose more than $440 billion on Thursday.

Nvidia's stock logged its best post-earnings performance in two years Thursday as investors welcomed the company's outlook for sustainable strong growth.

The chip maker's (NVDA) revenue and next-quarter forecast came in ahead of Wall Street's expectations, but the real highlight was its early projection that revenue could jump more than 70% in the fiscal year that ends in January 2028. That preview was "potentially a needed catalyst for the stock," TD Cowen analyst Joshua Buchalter said in a note to clients.
