1) 5-10 P/S; faster growth is worth more, VRTX is 14. 20 is quite rich. It may stay at 20 +/- for some time, but not forever; as it gets some stability, it likely will moderate.
2) bcs I think with the rev growth the downside is limited. However, I'd believe the SP will grow, just not to the moon and just not as fast as many here say.
I share a similar sentiment. I don't think we will breach $30 without a buyout. My strategy will be to sell the news when the label is approved and buy back in after the correction.
