NEW YORK (AP) — Most of Wall Street is rising Tuesday, even as stocks of computer chipmakers continue to tumble worldwide. Oil prices, meanwhile, are easing further from the two-month high they hit last week.

The S&P 500 slipped 0.2% in morning trading, but the modest move masked big swings underneath the surface. The Dow Jones Industrial Average was up 402 points, or 0.8%, as of 10 a.m. Eastern time, and the Nasdaq composite was 1.1% lower.

The majority of the U.S. market rose after more companies delivered stronger profits for the spring than analysts expected. Coca-Cola climbed 7.1% after its revenue rose 7% despite what CEO Henrique Braun called “a dynamic consumer landscape.”

Sherwin-Williams rallied 8.3%, and Illinois Tool Works rose 4.8% after both likewise reported stronger profits for the latest quarter than analysts expected. Stock prices generally follow the trend of corporate profits over the long term, and expectations are high for this most recent round with the U.S. stock market still near its all-time high.

Such expectations are weighing particularly heavily on stocks of chipmakers and other companies that had been huge winners from the boom in artificial-intelligence technology.

Micron Technology’s stock has more than tripled this year following gangbuster growth, for example. During the quarter through May 28, its revenue more than quadrupled from a year earlier.

But worries are rising about whether such growth is sustainable. Big spenders on computer memory could pull back on their investments if AI does not produce as much profit or productivity as promised. Lower-cost AI models from China could also mean less demand for memory and basic computing power.

Micron dropped 10.8% and was the heaviest weight on the S&P 500. Others also helping to drag the market lower were Advanced Micro Devices, down 9.6%, and Nvidia, down 1%.

SpaceX, which owns the xAI business along with its rocket operations, sank 2.2% and at one point fell near $107. That was its lowest level since its stock began trading a month ago, down from a high above $225.

The losses for AI chip stocks were even sharper earlier in the day in other markets worldwide.

Sharp drops for SK Hynix and Samsung Electronics dragged South Korea’s Kospi index down 10.8%. The market’s losses were so big that trading was temporarily halted at times in Seoul.

“We believe the market was likely spooked by the progress of China’s chipmaking equipment capabilities, and was worried that this progress would threaten the competitive position of global chipmaking and chip equipment leaders,” said equity analyst Jing Jie Yu of Morningstar.

“That said, we believe the sell-off today is largely a knee-jerk reaction and overdone,” he said. The dominant position of global chipmaking leaders is unlikely to be threatened meaningfully, he said.

Several huge spenders on AI chips and data centers are scheduled to report their latest quarter earnings this week, which could offer updates on how much they're planning to invest. Meta Platforms and Microsoft are reporting on Wednesday, while Amazon is due on Thursday.

Because AI superstar stocks have grown so big, their movements carry more weight on the S&P 500 and other indexes than other companies. But Wall Street could hold up despite the swings for AI stocks if other, less-loved areas of the market are able to keep rising. It's a “rotation” that some strategists have suggested could be healthy for the overall stock market.

In the oil market, the price for a barrel of Brent crude to be delivered in October fell 2.4% to $83.85.

It's been falling since late last week, when the price for a barrel to be delivered in September briefly shot as high as $102.

Pushing up on prices have been worries that worsening fighting in the Middle East could further slow the global flow of oil. On the other side, though, are hopes that the United States and Iran could still negotiate something to allow oil tankers to use the Strait of Hormuz to move crude.

Lower oil prices helped to ease Treasury yields in the bond market. The yield on the 10-year Treasury fell to 4.61% from 4.65% late Monday.

A weaker-than-expected reading on confidence among U.S. consumers also weighed on yields in the bond market. Fewer consumers are saying they feel good about current business conditions, according to the latest survey released by the Conference Board Tuesday.
