Vertex is a company bringing in over a billion dollars a year. Some biotech's don't even have any revenue. A billion is a lot of money and Vertex in fact brings in much more than a billion. While Incivek sales may go down Kalydeco is going to increase. Current sales are just the tip of the ice berg. Vertex was completely over sold and should go up. Same thing happened last year. It dipped in November and then had huge jumps from there.
