Tomm Pfitzenmaier, Summit Commodity Brokerage, says wheat starts strong on fund shortcovering triggered by war and weather concerns, which pulls up corn.  Soybeans struggle to follow. Fund short covering produced this uncommon harvest rally but how long does a rally like this historically last and are the funds just about done buying? Cattle and hogs also see fund buying and push to new highs for the move.
