Tech Five: Microsoft, Amazon up next

It's a big day for tech earnings. Let's look at the tech stocks to watch Thursday:

Yelp. Shares plunged more than 17% after the online recommendations service reported a weak outlook for the fourth quarter. For its third quarter, Yelp raked in $102.5 million in revenue, a 67% increase from last year, and reported a 19% spike in monthly unique visitors.

Amazon. The retail giant reports third quarter earnings after the markets close. Amazon is forecast to report a loss of 73 cents per share off $20.9 billion in revenue, according to estimates compiled by Bloomberg. Earlier this month, media reports surfaced that Amazon would take its first step toward brick-and-mortar with the opening of a retail store in New York.

Microsoft. The tech titan will report first quarter earnings after the bell Thursday. Last quarter, Microsoft's profits slid thanks to the recently-acquired Nokia and its struggling cell phone business.

Pandora. The online streaming service joins the earnings parade with its third quarter results. Pandora is expected to report $239 million in revenue with an earnings per share of 8 cents.

Google. The creators of Gmail introduced a new app called Inbox aimed at simplifying email. It boasts features including highlighting attachments such as photos or documents in the subject line and grouping email by categories including Updates and Social. However, the app is invite only.
