Mobile gaming stocks traded higher Tuesday on the news Activision Blizzard is acquiring "Candy Crush" developer King Digital for $5.9 billion.

But investors may want to think twice before assuming this event will spark a wave of consolidation in mobile gaming.

Or even that the dealmaking makes any of these companies more valuable.
