The wheat speculator in Chicago declined the high net short positions in the last week of the report to the 19.05.2015 to 31.690 contracts on now 72.999 NET short positions. At the same time, the wheat prices in Chicago and also in Paris could recover. This recovery has more technical reasons (removal of the high net short positions) as fundamental reasons. In any case, no such vagaries of weather have taken place in recent days, that justify such price movements.
In contrast, the corn speculators in Chicago of your line remain faithful. During the reference week 19.05 2015, the net short positions to 18,160 contracts raised a total 134.740 NET short positions. Nevertheless the courses with a slight plus this pressure could escape. The weather will show it in the next few weeks as we continue with the corn.
