U.S. stock index futures were slightly lower Wednesday morning, as market participants looked ahead to another deluge of corporate earnings.
At around 02:45 a.m. ET, Dow futures slipped 17 points, indicating a negative open of more than 28 points. Futures on the S&P and Nasdaq were both seen marginally lower.
Market focus is largely attuned to earnings season, after better-than-feared figures from major companies in the previous session helped the Nasdaq and S&P 500 indexes reach record closing highs.
In corporate news, AT&T, Biogen, Boeing and Caterpillar are among the major companies expected to publish their latest quarterly results before the opening bell.
Facebook, Microsoft, PayPal, Tesla Motors and Visa are all set to release their latest quarterly figures after market close.
