Commodities have seen very strong growth over the last few years, underpinned by demand from the fast developing economies of China, India, Brazil and others.

However, copper - a bellweather for industrial commodities - has recently seen a dip in prices. Is this a buying opportunity, or a sign that the commodities super-cycle is coming to an end?

What about other commodities, such as food and oil? In which particular commodities is there value to be found?

Lastly, there has been substantial growth in financial products allowing private investors to buy into commodities. Does the arrival of retail investors underline the strength of the commodities market, or signal the end of the boom?
