-Hogs is a no brainer, we just need to go through the inventory first : Long a deffered spread I would say.
-For wheat, I also read somewhere that China may actually need SRW but the price is too high.
-Soybean is already fully priced as if stocks were huge this year and non existent next year. I wouldn'go long a 20/21 crop spread for sure.
-Crush spread can be a good idea but beware of soyoil rally.
-Cotton is also priced a bit like soybean( inverted in the next season ), so it is hard to be long deffereds. Ethanol needs China buying just to survive in terms of margin.
