I bought most of my shares in the 5's, so will add starting in the high 4's and all the way down into the 3's should the opportunity present itself. This stock traded as low as 3.25 early this year, but I doubt very much it will get anywhere near that low again. Mid 4's seem quite possible however, especially if the oil stocks correct ....
It's my investment style to average down when I perceive a good value ....
