The vote of confidence from Nvidia came just a few weeks after Intel agreed to a deal giving the U.S. government a 10% stake in the company. Intel shares skyrocketed 23% on Thursday, outpacing all other stocks in the S&P 500, while Nvidia stock was up 3.5%.

Shares of Intel partner Synopsys (SNPS), a provider of electronic design automation software used in the chipmaking process, jumped 13%.

CrowdStrike (CRWD) shares surged 13% after the cybersecurity firm offered an improved outlook for annual recurring revenue.

The steepest decline in the S&P 500 on Thursday belonged to shares of financial data and software provider FactSet Research Systems (FDS), which tumbled more than 10%.
