The known catalyst wasn't that great, all it was, was that the CEO participated in the ROTH meeting in California. The news was outdated which I forgot to look at. RNVA was up 40+ percent on the day an had excellent price action at the end of the day 3/18/16. Probably shorts getting squeezed due to it being Friday. I should have bought 20-30 mins earlier at around 80 cents and sell at the end of day around $1 instead of holding over the weekend. Cut losses quick, and stick to the rules.
