i don't see this stock rising more than $500 million to $1 billion upon introduction of the product. A lot of assumptions in this estimate and it could be way wrong but that is my best guess. I think that puts the stock at $15 to $20. I doubt think the stock will rise more than 30% of that value upon FDA approval. Investors hate this stock now that it has burned so many and taken so long to bring the simplest of their products to market.
