Corn futures traded lower last Thursday and this resulted in a break of key support at $682.00, the Jun 6 low and a bear trigger. The break lower ends the recent bullish theme and instead strengthens a bearish threat and signals scope for a deeper pullback. This has opened $631.00 next, the Mar 29 low. On the upside, key short-term resistance has been defined at $749.25, Jun 7 high.
