Actually there are message boards such as these that traders use to do exactly that ... Particularly on pdufa dates. If you watch you will see a run up the week or 2 leading up to fda decision followed by a sell off prior to the actual date. I guess traders dnt always like to hold stock on the day of the decision due to the fact it could go either way. I expect we will see something similar leading up too are pdufa date.
