I dip bought this 1st green day hot bio-tech at the end of the day with the goal of selling into a short squeeze into the close. Bio-techs are running hard this week and all of them have been squeezing into the close. I ended up cutting my losses quickly, thank God, because the stock tanked into the close. It's been a while since I've seen an afternoon panic like this one. You have to protect yourself - cut losses quickly!
