If you are looking to gain commodity exposure in your self-directed retirement plan, consider using one of a burgeoning number of possibilities that exchange traded funds (ETFs) offer. Head over to Instant ETF and browse by sector to find what you’re looking for. One of the most popular commodities right now is the Natural Gas ETF (AMEX: UNP). There are a lot of other options, including broader based ETFs and ETNs that cover a basket of commodities, including ones that do not just focus on energy. London has been somewhat ahead of New York in offering commodity plays, but there is an increasing number of commodities ETFs in the United States, primarily because of the strong bull market right now. If you’re looking at adding commodities futures contracts themselves, take a look at Commodities Futures Charts.
