It's happening again. A week after Tangoe (TNGO -18%) was hammered by a very critical report from The Street Sweeper, shares are diving due to an equally bearish report from Copperfield Research. Copperfield argues Tangoe's organic growth is much lower than is often assumed; notes deferred revenue growth is soft; and questions the backgrounds of Tangoe's management and VC investor Edison Ventures.
