U.S. stock index futures struggled for direction on Tuesday, as investors weighed the scope of upcoming reciprocal tariffs, a day after the Trump administration hinted that there might be a softer approach to the policies.

U.S. President Donald Trump said on Monday that not all of his threatened levies would be imposed on April 2 and some countries may get breaks, a move Wall Street took as a sign of flexibility on a matter that has roiled markets for weeks.

The benchmark S&P 500 and the tech-heavy Nasdaq closed at their highest level in over two weeks, propelled by a rally in megacap stocks including Nvidia and Tesla.

However, futures lost some ground on Tuesday as uncertainty over the scope of Trump's tariffs weighed on sentiment. A report also said the president is considering a two-step tariff regime next week.
