Commodities - 3 yrs down in a row or at least getting there. According to http://mebfaber.com/2015/07/16/three-years-down-in-a-row-system Meb Faber's research this is a very rare event and warrants serious consideration. Any recommendations for a commodity ETF? I am thinking DBC or DJP. Clive? have you done any research on this?
