My own personal opionion is to trade 1/2 your upside to eliminate any chance of downside. Sell half your shares anywhere over $2.60 and ride your free shares. If it goes up you will say "what if" but you will still be happy its going up, if it goes down you will be happy you cashed in and now have the cash to buy more at cheaper prices. I have learned to not dwell on the possible upside scenerio and focus on what currently is. You currently have a double, lock it in as a great trade and sit back while enjoying any future movement. Thats me sharing that as a fellow investor, I dont want anyone to sell a stock I own, but I want all of us little guys to make money when we can and not lose our @$$ when we can completely avoid it. Please only do what you can live with, because I do hope NVIV keeps going up!
