If I recall, yesterday in another thread you said you were short the stock. Only reason I recall is being surprised shorting a stock that's already so low when there are many others with much greater profit potential.
As stated by all, I too am concerned with the action but it could be it ran up too quick on a percentage basis and when the markets correct, the large % gainers get hit the hardest. Luckily, I got a little insurance and bought some real cheap $2.50 puts in case this happens because I can have crappy timing sometimes. The insurance may pay off this time.
