Not even. Last year it went down some due to uncertainty of the trial and a restatement. Vertex has multiple drugs that will continue to bring in billions. The recent partnership with BMS on some of its Hep C drugs. Vertex should be like PCYC and in general more and more investors will see the value. Just like Gilead did in hiv, Vertex will do in CF. With the new news next steps will be further analysts upgrading. I am in for the long run. Been happy so far since i bought at $32.
I disagree with you. Irrational buying is a sign of uncontrolled and stupid greed. For a stock to go up 61% on a phase II study without safety data is terribly disheartening of how stupid the investors are. Soon facts and reality will catch up with madness and sanity will win!
