It looks like RGEN has more than 5 million short interest, the news could be pretax for a blow out top. Please watch the price and volume action during last 15 minutes.
Oh wow! 20% of the float is short. The upside explosion potential on this one is huge!!!!
Sentiment: Strong Buy
It could be a trap, please watch out, someone owns the stock and is short at the same time. Today's action could be the short covering rally, you be the judge of next move, lock your profits.
