companies pop after an approval if it's a well run company, and it's a surprise. The old adage is buy on rumor, sell on news. There's usually a run-up to the approval date when an approval is expected.
In this piece of sh*t, it's a piss poor run company, with a con-artist CEO, that's taken a steaming dump on share-holders repeatedly the last several months, and that is only in this position because it f'd up the easiest part of the approval process (not having a piss-poorly run manufacturing facility). The people coming out of the woodwork screaming about this hitting 20.00 or whatever are pumpers that arrived late. I said it before, I'll say it again, if this holds 7.00 I'd be shocked.
It is important to listen to all the information, not just the stuff that makes you feel good about your investment.
