In Commodities We Trust
Trying to search for a commodities index fund or ETF, but didn't manage to find one. The closest thing I have found is an ETF called (IGE), which mirrors Goldman Sachs Natural Resources Index. http://www.etfconnect.com/select/fundpages/etf_funds.asp?MFID=78841 .
This ETF does not invest in the commodities, but the US companies in the commodities businesses. It consists of 75% oil and oil services. As I am long in Big Oil, I think it is a good proxy to include Oil and other commodities as well.
