The Dow notched a record high close on Thursday in mixed trading following robust U.S. economic data, while artificial intelligence chipmaker Nvidia dropped after its largely in-line forecast failed to impress investors.

The U.S. economy grew faster than initial estimates due to strong consumer spending, the Commerce Department reported, supporting expectations the U.S. is likely to avoid a recession.

"Downward revisions to inflation accompanying an upward revision to spending builds the case for a soft landing," said Jeffrey Roach, chief economist for LPL Financial.

Nvidia's quarterly revenue forecast late on Wednesday disappointed investors accustomed to the chipmaker beating expectations by massive margins in recent quarters.

Nvidia's stock fell over 6%, trimming its 2024 gain to 137%.

Other AI-related stocks were mixed. Microsoft gained 0.6%, while Google-owner Alphabet dipped 0.7%.

Broadcom and Advanced Micro Devices each slid almost 1%.

"It's too early to put the bear suit on for AI related companies. We think there's still more upside," said Terry Sandven, chief equity strategist at U.S. Bank Wealth Management. "We see the AI revolution still in the relatively early innings and that bodes well for tech names."
