Your wrong its not valued at $7. It was $12 and CEO announced to sell shares then stock falls as investors did not like.
Priced At a discount the buyer/investor. So they were discounted to the lower price. Supg's investors stayed clear believing those shares will be sold and price will go lower which they did as market also did'nt help much...
It was Supg who in reality caused them to fall. It made it more attractive to find an investor to buy. Now Supg has their money and buyers have theirs.
I am sure Supg realized their drugs were doing good at this point. A little slip of the tongue with information on the drug to the investors that could have been released prior at last conference would have keep stock price higher. At this point they had to give same informaton to the public.
The stock price reversed and went up with the good drug news from the trial.
So in reality if Supg was still at $12 instead of $6's before selling shares last month, we would have been at $18 last Friday instead of $12's right back were we started.
