Cheers wake but do you have any quick explanation to why DIG would be down when oil is down? I'm reading through the holdings as we speak.
You are sadly mistaken. OIH is not a very accurate "proxy" for shorting crude oil. The OIH is an oil-service index. 83% of the components are: BHI CAM DO HAL NOV NE SLB SII RIG WFT
USO is the best pure oil ETF. OIH is like a combination of oil and the general stockmarket. If both go up it can do even better. If oil is up but the S&P is down a lot, the OIH may be unchanged or even down.
USO. Thank you. I've been looking for something like this. I've been just trading OIH. You are right. USO follows oil much better.
If you want to short oil, aren't you just better off buying XOM? They make more money when the inputs are cheaper. Valero and Tesoro are other pure play refiners.
