Wall Street stocks suffered another blow on April 10, giving back a significant portion of the gains from the previous session, AFP reports.

Major US indexes spent the entire day in the red, disappointing traders who had hoped to extend the April 9 rally when Donald Trump delayed tariffs on all countries except China by 90 days.

The broader S&P 500 index ended down 3.5% at 5,268.05 points. On April 9, the index had risen 9.5%.

The Dow Jones industrial average fell 2.5% to 39,593.66 points and the technology-rich Nasdaq Composite index fell 4.3% to 16,387.31 points.

U.S. stocks wiped trillions of dollars off their value in the sessions following President Trump's "Emancipation Day" tariffs announcement before the president made a U-turn on April 9.

But a day later, investors realized that Trump's tariff pause "wasn't enough to get people back into this market," said Peter Tuchman, senior trader at TradeMas Securities.

"There's still no clarity," Tuchman said. "We're still in the middle of a major trade war with China, so where do we go from here?"

Data showed that US consumer inflation contracted 0.1% from a month earlier in a reading that was lower than analysts had expected.

However, traders were unnerved by Trump's massive policy reversals, leading to uncertainty that economists warn could paralyze consumers and businesses.

"There's still a lot of concern," said Tom Cahill of Ventura Wealth Management, noting there's uncertainty about whether the Republican's tariffs will be rolled back in 90 days.

"Things can change in just a few hours with something as simple as a tweet," Cahill said. "Uncertainty is always present when you're an investor ... but the level of uncertainty is almost unprecedented in my 30-year career."
