US Stocks Fluctuate as Wall Street Braces for Trump Tariffs

US stocks flipped between small gains and losses following the opening bell on Tuesday after closing out their worst quarter in nearly three years, as traders await President Donald Trump’s next tariff deadline on Wednesday.

The S&P 500 Index was down 0.1% after suffering its worst quarter since 2022, which exposed weakness in the artificial-intelligence boom that has underpinned the two-year bull market. The Nasdaq 100 Index fell 0.1% after Monday’s tech shakeout eased toward the end of the session. Tesla Inc. climbed 2.1% following a 36% tumble in the first three months of the year ahead of its quarter deliveries data. Nvidia Corp. slipped while other Magnificent Seven stocks including Meta Platforms Inc. and Apple Inc. rose.

It’s been a dizzying three months for US equity markets amid uncertainty about what Trump will do with tariffs, and by how much his policies will worsen inflation and hurt economic growth. On Wednesday, Trump is set to reveal what he calls “reciprocal” levies on US trading partners, but details remain scarce. The Washington Post on Tuesday reported that the Trump administration is considering implementing tariffs of about 20% on most US imports.

“Buyers are afraid to step in right now with max uncertainty,” said Jeff Buchbinder, chief equity strategist at LPL Financial. “We really hope cooler heads will prevail and a full-blown trade war will be avoided, but the risk is more volatility is coming for stocks until we know more about the size and scope of tariffs and the subsequent impact on corporate profits.”
