Well... The deadline has passed for the FDA to reply to the congressional demand letter... But, if the response was made public then for sure, and no matter if it was a positive or negative response, either way it would affect the share price. So will we ever know until it is a "go or no go" from the FDA? Seems we are stuck by the rules of insider information.
As to the halt of the case to negotiate. I think that is a good thing. There are a lot of institutional investors who carry a lot of leverage and I am sure they are not happy over all this. I think they want them to stop kicking the can down Wall street..
