NEW YORK (AP) — U.S. stock indexes rose Wednesday after Wall Street got some relief from an encouraging inflation update. But even on a rare up day for the market, President Donald Trump’s trade war still knocked stocks around.

The S&P 500 gained 0.5% after skidding between an early gain of 1.3% and a later loss. The unsettled trading came a day after the index briefly fell more than 10% below its all-time high set last month.

The Dow Jones Industrial Average also pinballed sharply, careening between a rise of 287 points and a drop of 423. It ended with a loss of 82 points, or 0.2%, while the Nasdaq composite climbed 1.2%.

The inflation report, which showed overall prices rose less for U.S. consumers last month than economists expected, helped companies in the artificial-intelligence industry lead the way. It’s a bounce back after AI stocks got crushed recently by worries their prices had gone too stratospheric in the market’s run to record after record in recent years.
