According to Business Insider, GameStop's second quarter shares declined early Friday. The video-game retailer posted adjusted earnings of 0.05 a share, missing the Wall Street prediction by three cents. The gaming store's sales totaled $1.65 billion, down from last year's $1.69 billion, but that still beat the $1.62 billion estimate. Meanwhile, comparable sales dropped 0.5%, beating the 3.7% decrease that was projected.
