I didn't realize it at the time but in retrospect the great grain bull market of early 2008 peaked on the liquidation of the rogue trader at MF Global which stuck the firm with a $141 million dollar loss. The best explanation of the circumstances are in the DOJ press release:
DOJ: MEMPHIS AREA MAN INDICTED FOR CAUSING MF GLOBAL TO LOSE $141 MILLION ON UNAUTHORIZED TRADES OF WHEAT FUTURES CONTRACTS AT CHICAGO BOARD OF TRADE IN 2008
