Tech Five: Expectations low for Twitter earnings

Twitter is set to announce its second quarter earnings Tuesday, and expectations are pretty low. As the social networking site experiences sluggish user growth, analysts are predicting yet another quarterly operating loss for the company.

Let's take a look at the tech stocks to watch Tuesday:

Twitter (TWTR): Rosenblatt Securities expects Twitter to post operating and net losses of more than $500 million in 2015. Twitter has had a rough ride lately as it struggles to find a new CEO after Dick Costolo stepped down last month, and its competitors -- Google and Facebook-- pull ahead. Company shares were slightly down during pre-market trading.

Yahoo (YHOO): Yahoo is making multiple moves this week. It has begun streaming a daily Yahoo News Live broadcast anchored by Katie Couric. The program airs live at 1 p.m. ET on weekdays. Today, Couric interviews Republican presidential candidate Mike Huckabee. Couric joined Yahoo in November 2013. On Wednesday, Yahoo announces a new consumer product in New York City. The search and digital tech giant has seen its shares fall nearly 5% since its second-quarter earnings were announced last week. It beat on revenue, but missed on earnings.

Cisco (CSCO): Cisco welcomed new CEO Chuck Robbins Monday, ending the leadership of John Chambers, who successfully headed the company for the past 20 years. In a company blog post Monday, Robbins announced other management changes at the top, and said the company will continue to leverage digital as its most valuable asset. Company shares were slightly up during pre-market trading.

Google (GOOG): As Google continues to wean itself off of Google+, the company announced yesterday that users will no longer need public profiles to engage on the company's various platforms. Google+ was intended to be a rival to Facebook, but failed to gain significant traction among users, and was rather seen as a burden for those who had to sign up for the service to access other platforms. Company shares were slightly up in pre-market trading.

Microsoft (MSFT): Microsoft is gearing up to officially release its Windows 10 update tomorrow, and the company has started pushing the new operating system out to customers who reserved it in advance. This will be Microsoft first major update since Windows 8, and this roll out comes after the company ended its fiscal year Tuesday with earnings and revenue that topped analyst expectations, but took a hit from the global slowdown of PC sales.
