Sell off could occur but it does not matter. Likelyhood of the news being +ve is 30% regardless this will be a good opportunity to loadup on DNDN if it does trade below $3 thanks to the shorts on this stock. I give a 40% downside at max on any news that would not likely result in an approval or increased chance of an approval in the interim. Mgmt has already dashed all hopes of a +ve interim trial result and has indicated that the final trial outcome will be better served. Read the news releases and listen to the conf. calls before jumping to conclusions. Shorts watch out if the news is in the 30% camp.
