Corn futures are trading lower at midday. Overbought conditions and expanding harvest progress are weighing on the market. Initial support was short-lived but came from follow-through fund buying and strong weekly exports. Export sales of 45.6 million bushels were above expectations and commitments for the marketing year are 44% above last year's pace. December is 1 1/2 cents lower at $2.72 3/4 and March is 3 1/4 cents lower at $2.84 1/4.

Soybean futures are trading higher at midday. Strong weekly export sales and fund buying are supporting the market. Commitments of 43.9 million bushels were well above trade expectations and for the marketing year sales are running 55% above year-ago. Harvest pressure is expected to limit gains, but momentum has turned higher. November is 7 3/4 cents higher at $5.63 and January is 7 1/2 cents higher at $5.77.

Wheat futures are trading higher at midsession. Follow-through buying from the strong gains on Wednesday is supporting the market. Shrinking stocks of wheat globally and fund money being diverted into ag commodities are supporting prices despite another disappointing weekly export sales report. CBOT Dec is 7 1/2 cents higher at $4.72 1/2, KCBT Dec is 6 cents higher at $5.10, and MGE Dec is 1 1/2 cents higher at $4.87.

Cattle futures are higher at midday. Reports of some $92 cash trade in Texas pushed prices higher. However, gains are being limited by poor packer margins and ideas that packers will soon slow slaughter rather than raise bids for cattle. October is 38 cents higher at $90.75 and December is 38 cents higher at $89.65.

Lean hog futures are higher at midsession. Gains are being attributed to steady to higher cash hog bids. Packer margins have turned negative recently, but demand from packers has remained strong as they have raised bids to fill slaughter schedules. October is 68 cents higher at $65.20 and December is 78 cents higher at $61.40.
