No one really knows if the shorts have been covered. Won't know till May 11th when the short interest is updated. I doubt this effects a multi-day run this coming week due to more than one catalyst that will be setting this off. We already took out 2 catalysts ( FDA Approval and Short interest most likely ). The other 2 (Euro approval and milestone payments) are coming ahead which will cause a multi-day run and a slow uptrend.
