U.S. stock index futures were slightly lower Tuesday morning.

At around 2:20 a.m. ET, Dow futures dipped 131 points, indicating a negative open of more than 118 points. Futures on the S&P and Nasdaq were both marginally lower, after climbing to record closing highs late last week.

Wall Street stocks were closed on Monday, as investors observed a market holiday.

Apple has cautioned it does not expect to meet its quarterly revenue forecast, citing slowed production and weakened demand in China as a result of the coronavirus outbreak.
