Grain markets showed a mixed performance today, with December Corn futures up $0.02 to $4.36 and the March contract up $0.015 to $4.495 as volume shifts due to December options expiration this Friday. January Soybean futures posted a new high for the move before reversing and settling $0.0375 lower to $11.535. The March Chicago Wheat futures contract gained $0.005, settling at $5.59. The USDA confirmed a flash sale of 792,000 metric tons of U.S. Soybean futures to China, which analysts suggest helped spur Monday's rally. Weekly export inspections for Soybeans came in at 1.176 million bushels, within expectations. Corn inspections were strong at 2.053 million bushels, exceeding the top end of expectations and maintaining a pace well ahead of last year. Wheat inspections were 246,000 metric tons, just below the low end of estimates.
