Rovio shares crash 19% after Angry Birds maker’s disappointing first post-IPO earnings

Almost two months after its IPO, Angry Birds maker Rovio Entertainment today learned a painful lesson about life as a public company when investors battered its stock following an earnings report that failed to meet expectations.

Rovio missed on both profits and sales, which sent its stock down 18.87 percent in mid-day trading on the Helsinki exchange, dipping below its IPO price.
