The USDA's monthly stocks to use report is out tonight. The market is expecting a bigger carryover of corn than forecasted but there is an 'outside' chance ethanol production has ramped and offset and reductions in exports for corn. (I'd say this is fairly likely). This report will be a very import directional indicator for which way corn futures trade in the short and medium term. Longer term though the trend is but one way though and that is up.
