One of the advantages of owning commodities is that they have a low correlation to equities and bonds. By adding a low correlative asset to a portfolio, you lower the overall risk.
This fund brings a new level of transparency to the underlying commodities-futures market, and also allows investors to trade throughout the day.
A sector stock fund doesn't give one true exposure. There are times when the underlying commodity is moving and the companies are not. It's a different investment. So, when you're looking for true diversity, you want a direct relationship to the commodity.
Adding commodities to a portfolio is a great diversification benefit.
