What’s up with IMAX? Just about everything over the last week or so, it seems — contributing to an 11.7% spike in the stock price since last Wednesday. It touched a 52-week high this morning ($33.88) bringing it to its highest level since mid-2011. IMAX likely will benefit from Paramount’s announcement yesterday that it will release Mission:Impossible 5 on July 31, ahead of the previous plan for Christmas Day.
