Shares of WWE (NASDAQ:WWE) are up more than 30% so far in 2015 It's perfect timing with WrestleMania 31 taking place this Sunday. (I remember the first one in 1985. Hulk Hogan and Mr. T! Cyndi Lauper!) But many investors may still feel like they're stuck in a choke hold: The stock is trading about half of what what it was worth last March when it topped $31 a share. Is there going to be another post-WrestleMania slump like last year? Company is excited about the new WWE Network -- a streaming video app that would give subscribers willing to pay $9.99 a month access to current and archived events, such as WrestleMania -- which is the "sport's" Super Bowl. Currently WWE is trading at $16.65 with +1.83% rise.
