Ahead of earnings from Microsoft and Amazon.com, Estimize Senior Vice President Christine Short said Thursday that only one appeared positive.

"Microsoft—I think investors were very excited about the new Windows 10 that was sort of previewed in the last week or so," she said. "So, I think we're looking for Microsoft to be a little bit stronger but (it) should give us some idea about where tech is going because we've gotten some mixed signals this season."
