U.S. stock index futures were lower on Tuesday morning, as traders waited to hear from Federal Reserve Chairman Jerome Powell.

At around 04:52 a.m. ET, Dow futures slipped 112 points, indicating a negative open of more than 119 points. Futures on the S&P and Nasdaq were also lower.

Wall Street closed lower on Monday on the back of negative sentiment in the tech sector. However, the big focus this Tuesday is on the Federal Reserve. Jerome Powell will give a testimony at 8:45 a.m. ET. This comes just after a stronger-than-expected jobs report raised questions about the central bank's rate policy.
