Its possible that it could go to 21 although it looks like there would be pretty heavy resistance at 22 it would take another quarter of bad news to accomplish something like that imo.
On the other hand the upside potential of going to 29 (yesterdays open) to 35 which was the previous analyst 1 year target is a pretty good risk reward. 6-10 dollars up for 3 dollars down with a dividend if I choose incorrectly.
Also I have done pretty well trading stocks by buying after a missed earnings report in the middle of heavy CAPEX spending. The market seems to miss judge what the CAPEX is... revenue that will not be spent on growing the business and will hit the bottom line when the build out is complete and analyst are "surprised" and up there expectations. Now (or soon) is the time to buy.
