Prices better - but why????

Wednesday's market was a "fat" market. The animals had been fattened and were ready for the abattoir. Today's market was a "stores" market. The animals were being sold on to other farmers to be finished before slaughter at a later date. Yet the sellers were happier with the prices they were getting for an unfinished product today than they had been for finished animals on Wednesday!
Was it (as some suggested) because there is a rise in confidence about prices with the lifting of the export ban imposed with Foot and Mouth? Or was it (as one cynic suggested) because the buyers on Wednesday were dealers who knew exactly how much money they could make, whereas today's buyers were farmers who (if they had done their sums) wouldn't have paid so much!?!
