Soybean futures finished mixed on Tuesday as the market weighed increased global production against slowing Chinese demand. Prices started lower but found buyers to push back up, with the January contract reaching a high of $10.92. Corn futures moved lower in a "buy the rumor, sell the fact" reaction to the USDA report, remaining stuck in the same sideways channel seen for the last two weeks. Wheat futures fell after the USDA raised global production estimates, sending prices to new lows not seen since late October.
