Wall Street's main indexes opened higher Friday as traders raised bets on an interest rate cut by the Federal Reserve in December following commentary from policymakers, with tech stocks stabilizing after last session's rout.

The Dow Jones Industrial Average rose 56.4 points, or 0.12%, to 45,808.65 at the open. The S&P 500 rose 17.0 points, or 0.26%, to 6,555.77​, while the Nasdaq Composite rose 84.8 points, or 0.38%, to 22,162.834.

Nvidia shares dropped 2.8% in premarket trading after a volatile session on Thursday when the stock swung as much as 5% higher before closing 3.2% down.

The world's most valuable company surpassed third-quarter revenue expectations and forecast fourth-quarter sales above analysts' estimate late on Wednesday, while its CEO dismissed concerns about an AI bubble.

"Relief around Nvidia's results didn't last long as investors couldn't shake their fears that the AI boom might have gotten ahead of itself," said Dan Coatsworth, head of markets at AJ Bell.

"When markets remain on a knife edge, it's inevitable that some people will want to protect any profits by trimming positions. That selling behavior is likely to be what's dragging down markets."

Other chip-related stocks such as Advanced Micro Devices fell 2.3%, while Broadcom was down 1.3%.

Megacap and growth stocks also fell, with Meta Platforms down 1.1% and Microsoft losing 0.6%.
