Corn futures are fractionally mixed at midsession. The market has been choppy this morning, but light support has come from weekly export sales that were above expectations at 48.1 million bushels. Bearish fundamentals and technical weakness are limiting buying interest. March is 1/4 of a cent lower at $2.04 3/4 and May is unchanged at $2.14 3/4.

Soybean futures are trading higher at midday. Strong weekly export sales are supporting the market. Sales of 47 million bushels were a marketing year high and over four times the pace needed to reach USDA's export projection. Oversold conditions have also spurred some buying interest. March is 4 1/4 cents higher at $5.69 1/4 and May is 4 3/4 cents higher at $5.79 1/2.

Wheat futures are lower at midsession. Profit-taking on the recent rally is weighing on the market ahead of the weekend. Weekly export sales were at the low end of trade expectations at 12.9 million bushels. CBOT Mar is 2 cents lower at $3.24 1/2, KCBT Mar is 2 1/4 cents lower at $3.80 3/4 and MGE Mar is unchanged at $3.90.

Cattle futures are higher at midday after a lower open. News that Japan will halt U.S. beef imports initially weighed on the market. The ban was put in place due to an export shipment containing risk material that Japan has prohibited. Strength in the cash market this week has helped futures recover. February is 23 cents higher at $96.35 and April is 10 cents higher at $94.75.

Lean hog futures are higher at midsession. Steady to firm cash markets and ideas that Japan's reimposed ban on U.S. beef may help pork exports are supporting futures. Gains are small on ideas that cash strength will be limited unless pork cutouts improve. February is 45 cents higher at $59.10 and April is 23 cents higher at $63.80.
