NEW YORK (AP) — The U.S. stock market is slipping Thursday following a rebound for oil prices and mixed reports on the U.S. economy.

The S&P 500 fell 0.4% and is on track for a fourth drop in five days after setting its all-time high. The Dow Jones Industrial Average was down 24 points, or less than 0.1%, as of 10:15 a.m. Eastern time, and the Nasdaq composite was 0.5% lower.

A halt in the torrid run for stocks benefiting from the artificial-intelligence boom has slowed the U.S. market recently. Not even another blowout profit report from Nvidia was enough to kick it back into gear.

The chip company reported much stronger profit and revenue for the latest quarter than analysts expected, while also forecasting revenue for the current quarter that cleared analysts’ estimates. “The buildout of AI factories — the largest infrastructure expansion in human history — is accelerating at extraordinary speed,” CEO Jensen Huang said.

Such performances and such talk have become routine, though, and Nvidia’s stock swiveled between losses and gains before slipping 1.1%.

Some analysts said the muted reaction may have simply been because investors were locking in profits after Nvidia’s stock had soared nearly 70% over the prior year, more than double the S&P 500’s 27% jump. The broad AI industry is also getting criticism for becoming too expensive, as well as too circular as Nvidia has bought ownership stakes in companies that use its own chips that drive Nvidia’s revenue.

Pressure built on Wall Street, meanwhile, as the price for a barrel of Brent crude oil climbed 2.2% to $107.32 and trimmed its loss for the week. Oil prices have been swinging up and down with uncertainty about how long the war with Iran will keep the Strait of Hormuz shut, which is preventing oil tankers from exiting the Persian Gulf to deliver crude.

That helped push Treasury yields upward in the bond market, resuming their climbs following a slowdown the day before.

Climbing yields worldwide have cranked up the pressure on financial markets. They’re slowing economies and weighing on prices for stocks and all kinds of other investments. Besides driving up rates for mortgages, high yields could also curtail companies’ borrowing to build the AI data centers that have been supporting the U.S. economy’s growth recently.

The yield on the 10-year Treasury rose to 4.61% from 4.57% late Wednesday.

It had gotten near 4.63% earlier in the morning, after a report gave the latest signal that the U.S. job market remains in better shape than economists expected. The number of U.S. workers applying for unemployment benefits last week unexpectedly declined in an indication of fewer layoffs.

But yields then eased a bit following a discouraging preliminary report on U.S. business activity. Companies are feeling the effects of accelerating inflation and are seeing subdued growth in their order books, preliminary data from an S&P Global survey said.

“The damaging economic impact from the war in the Middle East is becoming increasingly evident in the business surveys,” according to Chris Williamson, chief business economist at S&P Global Market Intelligence.

Inflation is worsening even beyond the high oil prices caused by the Iran war, while U.S. households are showing widespread discouragement about the economy.

Elsewhere on Wall Street, Walmart fell 6.7% following its profit report. The retailer delivered another quarter of impressive revenue but offered up weaker forecasts for upcoming profit than analysts expected.

On the winning side of Wall Street was Ralph Lauren, which jumped 10.5% after reporting stronger profit and revenue for the latest quarter than analysts expected.

In stock markets abroad, indexes were mixed in Europe following big jumps in some Asian markets.

South Korea’s Kospi Kospi soared 8.4% thanks to strength for technology stocks. Samsung Electronics jumped 8.5% after its labor union and management reached an agreement late Wednesday that averted a potentially costly strike. SK Hynix, a chip company partnering with Nvidia, surged 11.2%.

Tokyo’s Nikkei 225 jumped 3.1%, though indexes fell 1% in Hong Kong and 2% in Shanghai.
