I am wondering the same as well. This is either a bargain or a value trap.
I have been following this stock on and off since July, when a lot of Nov 15 calls were bought in anticipation of the approval in November. Just a few days ago this stock was trading at 11, now it is $2 lower. Just a return to the $11 level would be a 20% plus return. I don't know if this stock is down due to the overall market being down or if someone knows something.
Do you own any stock in CADX? For someone who doesn't own any, what is a better play - buy the stock or buy calls?
