Sept 8 calls--a good speculation imho
But don't overpay! I guess someone had a market order the other day, and bought some at $0.8! Today I put in a limit a bought a feww more at .15! USE LIMIT ORDERS. Stll think we get to $2 (.15 to 2 is a 30-fold gain) or higher by expiration. So even the person that bought at .8 should have a nice profit. Crops are floundering and yields will be lower than usual.
The best part of GRU is that is pure grain--Corn, Soybeans and Wheat. A pure play.
