Commodity ETF

How do I invest in a broad commodities basket?

Investing in commodities is considered risky. However, from a diversification perspective it can be interesting to invest in commodities. In particular, the historically negative correlation of commodities to stocks can improve portfolio diversification. A commodities investment is generally realised through an investment in forward or futures contracts. Commodity indices usually track a basket of commodities.

There are several indices available to invest with ETFs in a broad basket of commodities. There are also subindices on single or selected commodity segments, which are usually derived from broad basket indices. This Investment Guide will help you navigate among the peculiarities of the most important commodity indices, which vary substantially in their methodologies. It will allow you to find the most suitable ETFs for you by ranking them according to your preferences.
