It's been just three trading days since social game maker Zynga (ZNGA) reported earnings, yet shares had gained 40% at today's high. Not only were investors optimistic about last quarter's results, but shares also got another boost today in the form of an analyst upgrade. UBS has upgraded the stock from "neutral" to "buy" while similarly pumping its price target from $4 to $6. CEO Don Mattrick is starting to put a turnaround together, starting with cost-cutting and the $527 million acquisition of NaturalMotion.

Many investors may be tempted to remember the botched acquisition of OMGPOP, which took only six months for Zynga to recognize its mistake. However, NaturalMotion has innovative technologies such as its Euphoria animation engine that powers numerous popular gaming titles among different platforms. Euphoria is one of several possible licensing opportunities that Zynga has going forward, and the foundations of a turnaround are now visible. Still, Zynga will need to get past its image as a shameless copycat if it ever wants to win investors back.
