Tech Five: GameStop shares surging

Video game retailer GameStop is off to a hot start in early trading. Let's take a look at the tech stocks to watch Wednesday:

GameStop. Shares jumped nearly 12% in pre-market trading after reporting holiday sales that were better than expected. The retailer says total global sales hit $2.97 billion, down 6.7% compared to last year. CEO Paul Raines says consumer demand for video games during the holidays was "strong."

Google. According to Reuters, the tech giant joined Apple, Intel and Adobe in settling a class action lawsuit that accused them of working together to avoid stealing each other's employees. Tech workers who filed the suit claim the actions made it tougher for them to switch jobs and kept salaries down.

GoPro. Shares are up more than 1.2% in pre-market trading following an ugly Tuesday that sent the high-definition camera maker's stock price plunging more than 12%. The reason? Apple filed a patent for a wearable sports camera similar to the GoPro.

IBM. Big Blue unveiled its z13 mainframe, a mobile-focused computer system that features real-time encryption and analytics. The company says it's "one of the most sophisticated computer systems ever built."

LinkedIn. The professional social network plans to add new features that will allow employers and employees of the same company to use the service together, reports Re/code.
