How major US stock indexes fared Tuesday 5/12/2026

A sudden halt for technology stocks put the brakes on Wall Street’s record-setting run.

The S&P 500 dipped 0.2% Tuesday from its all-time high set the day before. The Dow Jones Industrial Average added 0.1%, and the Nasdaq composite sank 0.7% from its own record. Stocks that had roared higher in the artificial-intelligence boom were some of the market’s heaviest weights.

The pullback began in Asia, where South Korea’s Kospi index tumbled 2.3% on worries that the government may redistribute windfall AI profits to its citizens. Oil prices meanwhile rose more than 3% as the war with Iran threatens to drag on.

On Tuesday:

The S&P 500 fell 11.88 points, or 0.2%, to 7,400.96.

The Dow Jones Industrial Average rose 56.09 points, or 0.1%, to 49,760.56

The Nasdaq composite fell 185.92 points, or 0.7%, to 26,088.20.

The Russell 2000 index of smaller companies fell 27.81 points, or 1% to 2,842.83.

For the week:

The S&P 500 is up 2.03 points, or less than 0.1%.

The Dow is up 151.40 points, or 0.3%.

The Nasdaq is down 158.87 points, or 0.6%.

The Russell 2000 is down 18.38 points, or 0.6%.

For the year:

The S&P 500 is up 555.46 points, or 8.1%.

The Dow is up 1,697.27 points, or 3.5%.

The Nasdaq is up 2,846.21 points, or 12.2%.

The Russell 2000 is up 360.92 points, or 14.5%.

Wall Street drifts to a mixed finish after Micron soars and Apple drops

NEW YORK (AP) — The U.S. stock market meandered to a mixed finish Thursday after several artificial-intelligence stocks veered back up their roller-coaster ride, while Apple dropped after hiking prices on many of its products. The S&P 500 finished nearly unchanged with a dip of less than 0.1% after swinging between gains and losses throughout the day. The Dow Jones Industrial Average added 71 points, or 0.1%, and the Nasdaq composite fell 0.5%. Micron Technology helped lead the market after jumping 15.7%. The maker of computer memory reported much bigger profit and revenue for the latest quarter than analysts expected, and it gave a stronger growth forecast for the current quarter than Wall Street expected. That helped allay worries a bit that its stock had grown too expensive after coming into the day with a surge of 267% so far this year. Micron and AI stocks broadly have been under pressure recently because of worries that their profits can’t possibly keep pace with the tremendous rallies for their stock prices. But beyond Micron, Qualcomm said late Wednesday that the acceleration of the AI era is forcing it to upgrade forecasts for its own growth in upcoming years. They’re the latest signals of the deluge of dollars heading into AI data centers and other investments.
