S&P 500, Dow close slightly up; Nvidia gains after the bell

US stock market: The S&P 500 and Dow Jones industrials eked out small gains on Wednesday, while the Nasdaq closed lower for a third straight session as investors awaited the release of Nvidia's earnings that could determine near-term momentum for equities.

After the closing bell, Nvidia shares surged 6 per cent after it forecast fiscal first-quarter revenue above estimates on robust demand for its chips that dominate the market for artificial intelligence (AI).

During the session, Nvidia (NVDA.O), opens new tab shares fell 2.85 per cent, adding to the previous day's decline of more than 4 per cent for the chip designer. Nvidia shares have soared nearly 40 per cent this year, making it the biggest gainer on the S&P 500 after a leap of almost 240 per cent in 2023. Analysts had cautioned that its lofty valuation could make the stock vulnerable to a sharp pullback if the company delivered anything short of a blowout report.

"It's been driven by excitement and enthusiasm around AI and of course the AI darling in the room is Nvidia," said Jason Ware, chief investment officer at Albion Financial Group in Salt Lake City, Utah.

"Markets are looking at Nvidia with a little bit of anxiety, maybe ... we need to see a good report from the leader in the space and that leader is Nvidia."

The S&P 500 climbed 0.13 per cent to end the session at 4,981.80 points. The Nasdaq declined 0.32 per cent to 15,580.87 points, while the Dow Jones Industrial Average rose 0.13 per cent to 38,612.24 points.

Energy shares (.SPNY), opens new tab led gainers with a rise of 1.86 per cent.

Wall Street's 2024 rally ran into turbulence last week after data hinted at sticky inflation, raising concerns the Fed would be in no hurry to cut interest rates. The January inflation data complicates upcoming rate decisions, Richmond Fed president Thomas Barkin said.

Palo Alto Networks (PANW.O), opens new tab plunged 28.44 per cent after the cybersecurity firm forecast third-quarter billings below analyst estimates. Shares of other cybersecurity companies such as Fortinet (FTNT.O), opens new tab, Zscaler (ZS.O), opens new tab and Crowdstrike Holdings (CRWD.O), opens new tab were also weaker.

Amazon.com (AMZN.O), opens new tab edged up, with the company set to join the Dow Jones Industrial Average effective next week, replacing Walgreens Boots Alliance <WBA.O>, which saw its shares decline.
