there is no way the stock will go up tomorrow. The data regarding this drug is great and that was previously known will not change. The issue surrounds manufacturing at the Hayward facility. The company is also trying to remove this facility from the approval process(it was a backup manufacturing facility) to expedite things
In all likelihood, initially the stock will drop with stop losses being taken out and than a bounce back with the hope it comes back close to where it now stands. Perhaps before the open tomorrow the company can offer something positive to instill some confidence in an approval. It is quite unfortunate that a drug that can really help some people is being delayed because the company couldnt get their facility in adequate condition. They should have a conference call on this and provide some answers.
