04:17 PM EDT, 08/27/2025 (MT Newswires) -- The S&P 500 notched a new all-time peak on Wednesday as traders set their sights on technology bellwether Nvidia's ( NVDA ) latest earnings due out after the closing bell.

The benchmark equity index rose 0.2% to 6,481.4, a new closing high. The Dow Jones Industrial Average advanced 0.3% to 45,565.1, while the tech-heavy Nasdaq Composite edged up 0.2% to 21,590.1. Most sectors ended higher, led by energy.

Chipmaking giant Nvidia ( NVDA ) is scheduled to report its latest quarterly financial results after the closing bell Wednesday, along with other names such as CrowdStrike ( CRWD ) , Snowflake (SNOW), and HP (HPQ).

Earlier this week, Tigress Financial Intelligence expected Nvidia ( NVDA ) to report record quarterly results amid robust demand for data center processors and its Blackwell generative artificial intelligence system.

"The key will also be (Chief Executive Jensen Huang's) commentary on AI processor demand, which he continues to highlight as unprecedented with no letup in sight, and expectations of a significant increase in revenue and earnings growth guidance," Tigress said in a Monday client note.

Nvidia ( NVDA ) carries the largest weight in the S&P 500, at about 8%, "so its guidance can sway broad portfolios," Saxo Bank Investment Strategist Ruben Dalfovo said in a report published Tuesday.

Nvidia ( NVDA ) shares closed 0.1% lower on Wednesday. The stock is up about 35% so far this year.

MongoDB ( MDB ) shares were up 38%. The database software maker late Tuesday lifted its full-year outlook on the back of stronger-than-expected fiscal second-quarter results.

Kohl's (KSS) raised its full-year earnings outlook on Wednesday as the department store chain recorded fiscal second-quarter results above market estimates. The company's shares surged 24%.

J.M. Smucker (SJM) shares dropped 4.4%, among the worst performers on the S&P 500. The food producer's fiscal first-quarter results fell more than Wall Street's expectations year over year, though the company increased its full-year sales growth outlook mainly due to the strength of its coffee portfolio.

US Treasury yields were lower, with the 10-year rate losing 2.6 basis points to 4.24% and the two-year rate marginally lower at 3.63%.

Federal Reserve Governor Lisa Cook should go on leave even as she intends to legally challenge US President Donald Trump's move to fire her, CNBC reported Wednesday, citing Kevin Hassett, Trump's top economic adviser.

Trump recently informed Cook in a publicly shared letter that he had determined "sufficient cause" to remove her from the Fed's board of governors. Trump said Cook may have made "false statements on one or more mortgage agreements."

West Texas Intermediate crude oil was up 1.1% at $63.93 a barrel in Wednesday late-afternoon trading following a decline in the previous session.

"Crude futures steadied following Tuesday's slump after (US President Donald Trump) imposed 50% tariffs on most US imports from India, making good on a threat to punish one of the world's largest economies over its purchases of discounted Russian oil," Saxo Bank said in a report.

Commercial crude stockpiles in the US shrank more than expected last week as distillate fuel and motor gasoline inventories dropped, government data showed Wednesday.

The European Union is aiming to fast track legislation to scrap all tariffs on US industrial goods, Bloomberg News reported Wednesday, citing sources. The US and the EU finalized a trade framework last week.
