Thanks for your concern. I own approx 15 bio's now. Rest of them I traded back n forth because of high valuation. I always hold my core positions.
If you see, All the hep c Bio's r down today not only Coley n most of the bio's r in red. I don't think about daily fluctuations. I am looking at 1-3 yrs for all my core positions unless the fundamentals change.
