I think today was a bargain day for any long-term biotech buyers.
I'm assuming the Visium HF collapse has had quite a lot to do with recent sector weakness. For example they held 2.3 million shares in FGEN - next report I bet we see that as close to zero.
Definitely think PRTK has good risk reward here - decent chance someone buys them.
The ability to seamlessly switch from IV to oral is significant.
