My most recent stock buy was Harken Energy (HEC). Fourteen percent of my portfolio is invested in HEC. While a lot of other oil and natural gas stocks are near all time highs, HEC has been lagging, despite the big turn around during the last two years. HEC could easily double from it's current price.
As I write this, HEC is trading at a bid of 0.62 and ask of 0.63.
