Obviously, you 've not seen the stock price of companies like PEP, KO or MSFT when it was in it's hey day. They had billions of shares and their stock price was way over $20/share. This could easily hit $60 share w/positive news from the FDA and a partnership deal. This will be a 2-3 year hold minimum. If you don't feel comfortable, sell half in a year and let the rest ride. You will be rewarded nicely IMHO.
