Why shorting DEC ? The contango structure is pretty classic with a higher contango between MAR/DEC than DEC/SEP. My own feeling is that I dont understant why the contango is so weak compared to the low price /high stocks situation we currently have.
A couple of reasons: - The curve is too flat. Dec most of the time is at least at a discount to Jul. - Good technical support and seasonality for Sep/Dec. - Really good long term seasonals for Dec/Mar while the contango is weak.
@TraDaToR Thanks Dec is at a discount when price are high. Long SEP/short DEC is 90 % a long corn position for me. However you have a nice assymetry in this trade. And I agree on the week contango compared to low prices !
