Corn traders may be squaring positions before the weekend. After exhibiting considerable strength over the previous week, corn futures declined Thursday and have continued sliding today. There’s little fresh news, and the financial markets have essentially stalled. Thus, we suspect today’s corn slippage is the result of traders and funds squaring positions before the weekend and next Tuesday’s important USDA reports. May corn futures slipped 1.5 cents to $3.8975/bushel late Friday morning, while December lost 1.25 to $4.135.
