I have to admit I've been quite amazed at how quiet this stock has been. Down from a high of $15 to 60cents in March and risen from 60cents to 4.42. Having got in and out a number of times from the 0.90's I've made a truckload. Now holding 20K at avg of 3.60 but will hold as they have refinanced and paid down debt. Anyone else been successul with this - surely I'm not the only one?
