In recent years most commodities had a huge run up. The Reuters CRB Continuous Commodity Index climbed more then 200%. By definition as a bull market is maturing there is less and less upward potential. I am sure there are many good reasons for commodities prices to be where they are and the outlook might seems even better but that is usually the case at cyclical top of any bull market.
Bull markets often end in a spectacular rally one in which big profits are made quickly. Have we just seen that?, Is the commodities long term top is in place ?
That's is not my point but the odds for multi month/year correction are certainly increasing.
The CCI index had surely proved itself to be the one index to follow this asset class.
