So you now want to suggest if the share price of a biotech company does not move or goes down then it is sure their science is not good? And you want to speak about the Regeneron comparison?
January 1992 the R**n price was $20. Ten years later the share price was still $20. Thirteen years after the company started the R**n share price was only $5. Certainly this is a bad company with super bad science.
Of course 26 years after the company started the R**n share price was $345.
