GameStop Corp (NYSE:GME) falling in today’s session after announcing a lower forecast for its yearly sales. The company said comparable-store sales for the full-year will fall between 7.5 percent and 9 percent, a lower outlook than the previous forecast of 6 percent to 9 percent. This decrease comes off of the company’s dismal sales from last year, where they saw a decline of 4.6 percent to .88 billion. The change in forecast comes after the company also saw a bad holiday season, with sales dropping 4.4 percent overall. Not a big surprise for the mainstream gaming industry, which has continued to struggle due to the rise of casual gaming on mobile devices.
