Organovo Holdings, Inc. (ONVO)

[RandolRocketman]

This ticker has been a target of (unlawful) short selling in the past, probably due to the potential upside. ONVO does have a pretty good volume, and enough movement to trade it. I've been able to flip in and out with a pretty decent return this year, while still holding a position in case there is a buy out, or some other catalyst type event. Organovo's future prospects are real, with enormous upside potential, and it seems it's a fairly safe place to park speculation funds.
