I understand this company's success depends upon commodity prices, and just like trading any stock whose success is dependent on positive commodity prices, it's good to be long the stock when the market they are in is favorable, which it is now. They are usually not long term buy and hold companies, but great for swing trading. With oil prices still climbing, I don't see it as time yet to be short ethanol companies, but I'm sure that time will come again, as it does with all commodity price driven stocks.
