Tech Five: Facebook trading higher after earnings

Growth in mobile advertising continues to drive Facebook revenue. Meanwhile, Priceline shocked Wall Street after announcing its CEO has resigned.

Let's look at tech stocks to watch Thursday:

Facebook. The social network is one of the few bright spots during this tech earnings rush. Facebook revealed 82% of the company's first-quarter advertising revenue came from mobile. Overall, revenue was up 52% compared to last year.

Priceline Group. CEO Darren Huston is out effective immediately after an internal investigation found he violated the company's code of conduct connected to a personal relationship with an employee. Chairman Jeffrey Boyd will fill in as interim CEO.

PayPal. Shares of the mobile payments service are up after the company reported a spike in revenue for the first quarter. Revenue jumped 19%, with earnings per share of 37 cents, beating Wall Street forecasts.

Sony. The electronics giant reported an $818 million loss, smaller compared to the same time last year, reports The Associated Press. Sony also reported sales of $16.9 billion, down 6% from the year before.

Amazon. The online retailer is expected to report a first quarter profit when it shares earnings results after the bell Thursday. Analysts polled by S&P Global Market Intelligence forecast earnings of 59 cents a share.
