Low 16's seem very safe at this point...down 23% is absurd...no way it holds down there very long at all. Just depends if you want to find the perfect entry or if you are happy with just finding a very good entry. To make sure you get in, I'd say $16.50 is good enough...$16.25 would be ideal but it may not drop down that low. This thing is going to get a lot of attention this evening and into the weekend so don't miss your chance!
