i don't want to get into this fight but one thing i have learned from trading bios for the last 10 years is that anything can happen. if you hold and there is good news you make money. if you trade out and there is good news you miss potential big up side.
if you are holding and bad news hits your dead meat.
in this case i have owned this stock at .60 and sold half my shares friday because it could be most of the big move is in dcth. or maybe the stats are not so great. long run it seems to be a winner. i have traded in and out of stocks. one stock was scio. i missed the huge move up on fda app. and the j&j buyout because i was not holding a position when news hit. i think day trading or channel trading is not for the average investor. if you believe in a company, like the concept, always leave some shares long. you will be rewarded if your right and the company delivers.
