The S&P 500 ended Tuesday's choppy session slightly lower as investors waited for clarity on U.S. trade policy after President Donald Trump's latest tariff threats dampened hopes around talks with some trade partners.

Wall Street ended mixed a day after a broad sell-off in response to the Trump administration setting new tariffs on more than a dozen nations.

President Donald Trump is threatening to revive his trade war. Wall Street isn’t too concerned. Global markets were relatively calm Tuesday after Trump on Monday ratcheted up his tariff campaign — but extended the deadline to August 1 and said he was open to negotiations. That provided a sense of optimism for investors.
