The buyer should be asking that the shares be delivered. Sadly its possible that sales could be naked shorts protecting their previous naked shorts.
I would like to here a good argument on the value of shorts that justify their existance. Let alone naked shorts. Also, what do other markets do about naked shorts???? Does anyone know????? Do they allow this world wide???? Wouldn't this leave it open for financial terrorism??? What do makets in other parts of the world do???
