Verizon climbed more than 1% after beating earnings and sales estimates in its third quarter. The telecom giant earned $1.04 a share, 2 cents above estimates, while revenue jumped 5% to $33.16 billion. Increased revenue was driven by growth in Fios and Verizon's wireless business.

IBM shares fell 4.6% after the company reported a sharp decline in quarterly sales and reduced its full-year profit guidance. The tech giant reported a 14% drop in sales in its third quarter, missing analysts' estimates.

The motorcycle manufacturer expects to ship 265,000 to 270,000 units for the full year, down from at least 276,000, as it faces an increasingly competitive environment.

United Technologies (UTX - Get Report) added 2% after announcing a $12 billion share buyback program and a better-than-expected third quarter. Net income of $1.67 a share bested estimates of $1.55. However, revenue came in short estimates as currency exchange ate into the topline and amid engine-delivery delays over the quarter.

Yum! Brands (YUM - Get Report) jumped 5% after it said Tuesday it would separate its Chinese and U.S. businesses after several quarters of declining sales overseas.

Housing starts were a bright spot on Tuesday. Construction on new homes in the U.S. climbed 6.5% to 1.21 million in September, returning to June's level at an eight-year high. Economists had expected September starts to total 1.14 million.

"The September starts report suggests that the U.S. housing recovery might be regaining its footing, after the brief relapse during the summer months," Millan Mulraine, deputy chief U.S. macro strategist at TD Securities, wrote in a note. "Moreover, the strong performance in September should provide a modest lift to overall economic activity."
