Looking at corn July futures, we expect price to drop now to the 560 level. The orthodox peak was actually on April 27th where wave 5 ended near 684. The following rise to 735 was only wave B up of the overall downward correction, but it indicates that price is itching to go higher. 560 also represents a 38.2% retracement of the 5-wave rise of this thrust, which originated from a lower B-wave triangle. We expect that, after 560, price will recover near to the peak again and then fall still lower, reaching down closer to 61.8%. It will be inclined to hit the level of that 4th wave below.
As with other commodities such as crude oil, this rally from last year's bottom is itself only the upward part of a larger downward correction (a final C wave up of a larger B wave up, which will be followed by a larger C wave down) but may reach impressive highs before turning down again.
