According to http://finance.yahoo.com/news/propthink-momentum-continue-snss-investor-153202685.html
If sales is $500m, let's do some calculations to figure out what pps SNSS would be.
The profit margin is around 70% in the bio-tech industry, then the profit of the sales is $500m x 70%=$350m.
Let's assume that shares will be diluted to 70m within a few years, profit per share will be $350m/70m=$5/share. Take PE=20,
We come up with SNSS=$100/share within a few years.
