December corn was up 4 3/4 cents late in the overnight session. Weakness in metal markets this morning is being offset by solid gains in equity markets and a weaker US dollar. It looks like a this week will be a big one for harvest, but traders believe some of the harvest pressures have already been priced into the market on the sharp sell-off of the past two weeks. Harvest is expected to be 15%-20% complete in this afternoon's weekly progress update. The Cattle on Feed report on Friday showed only a 5% increase from last year versus trade expectations for an 8% jump. South Korean feed groups have been good buyers over the past few sessions. December corn closed 11 1/2 cents lower on the session Friday and down 53 1/2 cents for the week. The market pushed lower early, led by renewed concerns for fund selling when energy and metal markets were sharply lower and the stock market was showing losses. A turn up in the stock market, a turn down in the US dollar and strength in the wheat market helped to provide some temporary support, but the market still closed sharply lower on the day and right below the 200 day moving average. Ideas that the market was oversold after the recent sharp break and continued talk that the market will face extreme tightness this year helped lent support. Talk of lower yield estimates for next month's production update helped to offset talk from producers of better than expected yields, but fund sellers remained active into the close even with a gain of 26 cents in Minneapolis wheat. Traders see declining crop conditions since the start of September plus some freeze damage and a lower harvested acreage update as reasons to suspect lower production for the October report. The Argentine government believes that corn planted area could be 4.9 million hectares this season, which is up from 4.6 million last year. Traders also see improving demand on the recent sharp break from the highs. The Commitments of Traders reports as of September 20th showed non-commercial traders were net long 286,625 contracts, a decrease of 38,976 contracts in just one week. The aggressive selling trend of the fund trader is seen as a short term negative force, and the data is only through Tuesday of last week. Commodity index traders held a net long position of 358,470 contracts, down 158.
