The S&P 500 was flat in choppy trading Wednesday after the week's strong start on the back of encouraging inflation data and the U.S.-China tariff truce, as investors turned their attention to global trade developments.
Eight of the 11 major S&P sectors were trading lower, although a 0.5% advance in information technology helped stave off larger losses.

U.S. stocks have been buoyed since the weekend, when the United States and China hit pause on their fierce tariff dispute, signaling a joint effort to stave off a global economic downturn.

"While there are undoubtedly still uncertainties and details to iron out with the trade negotiation with China, the easing of tensions is apparently enough for the markets," said Rick Gardner, chief investment officer at RGA Investments, in e-mailed comments.
"(Markets) are typically forward-looking and are pricing in an environment where the U.S. and China are able to trade with each other," he said.

A 90-day tariff pause announced on April 9 for countries other than China, along with solid earnings reports and a limited U.S.-UK trade agreement last week, helped the benchmark indexes claw back.
