It seems to be brutally punished for poor performance and guidance but the PE is not too high and it is near 2 year lows. I think it does not go much lower unless next earnings are horrible. It may drift higher.
I would say about 10% unless the earning get a lot worst is the downside. I do not see it going under $16. I think it has a lot more to the upside but these girls have really poorly managed this company. I say this is a buy after they prove a honestly good quarter.
