I saw Susannah's comment concerning a possible ETF on the english exchange for cotton. Does anyone know or have a list of ETF's that are based on a one tenth relationship between the futures price and the ETF price the same way Crude has the OSU or Silver having the SLV. Even if its an ETF based on a combination of corn, beans, and wheat or beans, meal, and oil. Just whatever. Cocoa, Coffee, Lumber. Any info would be very much appreciated.
