US stocks wavered on Tuesday after a solid day in the green for the major gauges and as investors weighed whether President Trump would temper his plans for upcoming tariffs .

The benchmark S&P 500 ( ^GSPC ) and the Dow Jones Industrial Average ( ^DJI ) hovered around the flat line, while the tech-heavy Nasdaq Composite ( ^IXIC ) rose 0.2%.

Uncertainty about the scope of Trump's upcoming tariffs has investors treading carefully. Stocks soared on Monday amid signs the administration could scale back reciprocal duties due on April 2, with the president saying he “may give a lot of countries breaks."

At the same time, though, Trump said fresh tariffs on the pharmaceutical and auto sectors are coming in the "near future." And in another abrupt salvo, Trump on Monday said the US would impose a "secondary tariff" on any country that buys oil or gas from Venezuela.

Meanwhile, worries about a risk of US recession persist as fears of tariffs and federal layoffs make headlines. Investors looking for fresh data on the economy's health will get readings on consumer confidence and February’s new home sales later Tuesday.

In individual movers, Tesla ( TSLA ) looked to build on Monday's 12% surge but wavered in early trading.

Quarterly earnings reports from Lululemon ( LULU ), GameStop ( GME ), and Dollar Tree ( DLTR ) are all due this week, with GameStop set to headline Tuesday's releases.
