Corn traders may have squared positions before the weekend. After exhibiting considerable strength over the previous week, corn futures declined Thursday and continued sliding today. There was little fresh news, and the financial markets essentially stalled. Thus, today’s corn slippage probably resulted traders and funds squaring positions before the weekend and next Tuesday’s important USDA reports. May corn futures slipped 0.25 cent to $3.91/bushel at Friday’s CBOT settlement, while December stalled at $4.1475.
