A choppy day in the markets left major U.S. stock indexes little changed Tuesday as the Trump administration pressed its campaign to win more favorable trade deals with nations around the globe by leaning into tariffs on goods coming into the U.S.

The S&P 500 slipped 0.1% a day after posting its biggest loss since mid-June. The benchmark index remains near its all-time high set last week.

The Dow Jones Industrial Average gave back 0.4%. The Nasdaq composite eked out a gain of less than 0.1%, staying near its own record high.

The sluggish trading came as the market was coming off a broad sell-off following the Trump administration’s decision to impose new import tariffs set to go into effect next month on more than a dozen nations.

Still, the modest pullback in the markets is a sign that Wall Street may be betting that the U.S. and its trading partners may eventually negotiate deals that will reduce or eliminate the need for punishing tariffs, said Ross Mayfield, investment strategist at Baird.

“I think today you’re basically seeing a market that doesn’t quite believe the worst of this is going to come to bear and is just kind of waiting for any sort of clarity because we seem back in that in that kind of phase where things change every couple of hours,” Mayfield said.

On Monday, President Donald Trump set a 25% tax on goods imported from Japan and South Korea and new tariff rates on a dozen other nations scheduled to go into effect Aug. 1.

Trump provided notice by posting letters on Truth Social that were addressed to the leaders of the various countries. The letters warned them to not retaliate by increasing their own import taxes, or else the Trump administration would further increase tariffs.

Just before hefty U.S. tariffs on goods imported from nearly every country around the globe were to take effect in April, Trump postponed the levies for 90 days in hopes that foreign governments would be more willing to strike new trade deals. That 90-day negotiating period was set to expire before Wednesday.

With the tariffs set to kick in Aug. 1, the latest move by the White House amounts to essentially a four-week extension of its previous 90-day pause, wrote Tobin Marcus, an analyst at Wolfe Research.

“At a very basic level, nothing actually happened based on Trump sending these letters, so there’s no reason to panic over headlines,” he wrote. “But we think these moves do contain some signal about where the trade war is heading, and that signal is mostly hawkish.”

During a cabinet meeting Tuesday, Trump said he would be announcing tariffs on pharmaceutical drugs at a “very, very high rate, like 200%.” He also said he would sign an executive order placing a 50% tariff on copper imports, matching the rates charged on steel and aluminum.

Shares in mining company Freeport-McMoRan rose 2.5% following Trump’s remarks. The price of copper for September delivery jumped 13.1% to $5.69 per pound.
