Alpha Natural Resources Given the recent improvement trends in the coal market, we now recommend a long position in its stock. This is because after acquiring Massey Energy Co., it is the top met coal supplier. In addition, it is very cheaply valued with its EV/EBITDA ratio of 4.8x being the lowest relative to its peers. Furthermore, it is extensively cutting down production, as is evident from the recent foreclosure of its four Kentucky mines, which is expected to improve its margins in future.
