As the Clash taught us, the future is unwritten. To answer your question, I'll sell when I get a better price for oil than today's price. Oil is currently sitting at a 11 year low. And, despite the slow down in Asia, oil is currently commanding record demand along with suffering through record supply. I expect the supply of oil to dry up before the demand for oil. So, I'm very bullish on oil's future and quite willing to hold onto it for a while.
Nothing cures low prices like prices. I can't tell you where oil will be tomorrow or where oil will be next month. However, I'm investing with the idea that oil will be higher next year, and alot higher five years from now. Going out of business sales don't last, and a lot of oil companies are going out of business.
