Corn can be a good way to diversify trading, and can be especially fun and profitable in the early summer months, with prices typically reaching their highest levels in late June and July. Trading remains volatile throughout the summer, with prices typically reaching lows in October and November as the harvest season for corn increases supplies of the grain dramatically. Corn is also a play on increasing use of biofuels, and with countries around the world working towards increasing their use of ethanol over crude oil corn stands to benefit greatly in the coming years.
