Contango burns off quite good for quite awhile, only remaining need is to cut off the small players, who deserve nothing in this ruthless cutthrout game. Maybe go to zero just to make a point, but not likely. The major point here..........steer clear of commodity ETF's in contango; stick with the underlying. If you can't handle the risk, you in the wrong playground. Contango markets can be hazardous to your health, early birds got to suffer the pain; part of the package. As in all markets, this one will go when ***least expected***, always been that way. CO
