Futures mixed as Street eyes earnings deluge

Wave of earnings flood Wall Street

U.S. stock index futures traded mixed on Thursday, amid a swathe of major earnings including, Caterpillar, McDonald's and General Motors.

Caterpillar matched estimates with adjusted profit of $1.27 per share, but revenue was short, and the company also cut its revenue forecast for the year. The heavy equipment maker cited currency impact and a soft economic environment, but said it is controlling costs and will be in position to take advantage of improving conditions when they occur.

The company's shares fell more than 3 percent in pre-market trade, weighing on the Dow futures.

Other firms reporting before the bell include General Motors and McDonald's, plus Bristol-Myers Squibb, Celgene, Dow Chemical, Eli Lilly and Raytheon.
