Stock futures were slightly lower on Tuesday as crude oil faltered after a massive rally a day earlier following weaker trade data from China. 

S&P 500 futures were down 0.48%, Dow Jones Industrial Average futures fell 0.39%, and Nasdaq futures slid 0.4%. 

Crude oil stalled after reaching a two-month high set a day earlier on further signs of weakening demand out of China. The world's second-largest economy reported a 25.4% drop in exports in February on weaker global demand and a week-long business shutdown during the Lunar New Year holiday. West Texas Intermediate crude oil was flat at $37.91 a barrel on Tuesday morning. 

Wall Street closed out Monday mixed with the S&P 500 and Dow extending their gains into a fifth session, but only by a hair. The Dow rose thanks to a rally in the energy and basic materials sectors, and the S&P 500 gained just 0.09%. The Nasdaq snapped its streak, pulling 0.19% lower due to pressure from high-momentum tech names.

Shake Shack (SHAK - Get Report)  fell nearly 10% in premarket trading following a softer-than-expected outlook for same-store sales growth this year.
