Certainly is the most important commodity far and away wether you like or not. Oil has come straight up in the last few weeks, So I don`t like to buy anything that is going straight up. I would suspect it is going to test its lows sometime in the next few weeks. That is normally what happens when you have a total collapse and you have a bounce. This is the way markets work.
