Lots of ways to do it but not all directly. EX:The ETF:DBC is a basket of commodities. But Corn has an ETF:CORN. Also the dependable spread trade of long Platinum/short Gold from about Dec into spring that is almost like clockwork can be done with the Platinum ETF:PPLT and the Gold ETF:GLD. Here is a link (bottom left) to Leavitt Bros site with the entire list of Sectors and Sector ETFs and Commodity with the Commodity ETFs and Currencies and Currency ETFs. At the bottom are all the breadth indicators that are used to measure strength and weakness etc. Lots of free stuff on this site along with educational tabs,short videos etc. Some do not have a lot of volume but they can all be traded in most any self directed account. They can be useful to futures traders to as most futures accounts are underfunded and use high leverage so are limited to what they can purchase. With a regular trading account including self directed retirement accounts one can trade these futures without extreme leverage risk or even hedge with them. There are also options on many of them as well. Lots of combinations possible along with many VIX related trades. There is even an inverse VIX that trades 'with' the SPX so if the market rallies like it has been without selling off like everyone expects it rallies even more. That one is XIV. Might as well post the chart I'm looking at.
