Tim Hannagan, PFGBest.com senior grain analyst, says the day prior to a crop report shows that commodity markets sometimes take on their own thoughts and ignore outside markets. 

"Traders are looking for a bullish corn report, by way of lower production. So, they are buying. Traders look for a neutral-to-negative bean report, but beans are seeing short-covering after beans yesterday hit their lowest price since Oct.11. And, the traders won't risk a surprise on the report. It's all about positioning for the report today," Hannagan says.
