Most U.S. stocks rose Tuesday following an encouraging report that showed inflation unexpectedly slowed across the country last month.

The S&P 500 climbed 0.7%, coming off an even bigger gain to start the week after the United States and China announced a 90-day pause in their trade war to allow for negotiations. The Dow Jones industrial average fell 269 points, or 0.6%, and the Nasdaq composite jumped 1.6% as AI and other tech stocks led the way.

Stocks have been roaring back since the S&P 500 fell nearly 20% below its record last month on hopes that President Donald Trump will ease his stiff tariffs on trading partners worldwide before they create a recession and send inflation spiking higher. The S&P 500, which sits at the center of many 401(k) accounts, is back within 4.2% of its all-time high set in February and positive again for the year so far.

On Wall Street, Coinbase Global jumped 24% after the cryptocurrency exchange learned its stock will join the widely followed S&P 500 index next week. That means many investment funds will likewise add it before trading begins on Monday. Coinbase will replace Discover Financial Services, which is getting bought by Capital One Financial.

Stocks in the artificial-intelligence industry were also strong. Nvidia rose 5.6% and was the biggest single force pushing upward on the S&P 500.

Super Micro Computer, which builds servers used in AI, jumped 16%. GE Vernova, which is hoping to power vast AI data centers, rose 4%. Palantir Technologies gained 8.1%.

They helped offset UnitedHealth Group, whose shares tumbled 17.8% after it suspended its full-year financial forecast due to higher-than-expected medical costs.

UnitedHealth was the main reason the Dow lagged behind other U.S. stock indexes.

All told, the S&P 500 rose 42.36 points to 5,886.55. The Dow fell 269.67 to 42,140.43, and the Nasdaq climbed 301.74 to 19,010.08.

In the bond market, Treasury yields ticked higher with hopes for the U.S. economy. The yield on the 10-year Treasury rose to 4.48% from 4.45% late Monday. The two-year Treasury yield ticked up to 4.01% from 3.98%
