Probably just because the share price had run up so much before the approval, so it was kind of baked-in already and some took profits. Also, maybe because of high price tag of the treatment. Still a bright future and should trend upwards.
Vertex set the price of Casgevy at $2.2 million compared to $3.1 million for Bluebird’s Lyfgenia. Bluebird’s gene therapy for thalassemia, approved last year, has a list price of $2.8 million.
The therapies are also not easy to receive. Patients must spend weeks, even months, in the hospital before and after the therapy is administered. And some of the preparatory steps can cause serious side effects, including severe infections, nausea, painful mouth sores, and infertility.
Hi JJ8, Re: CRSP price action..........................
My guess is it's a "Sell on the News" action. This isn't the first time CRSP has shown high amplitude price change as this histogram shows: https://schrts.co/NSfSbXYF
I think it will be important to watch the transition of this company from basically a 'research' business to one of product development and distribution. Somewhere along the way they'll have to show a profit to reward those who've invested in them. I'm fond of watching the Accumulation/Distribution activity to see what is happening with strong and weak hands holding the stock. In the mean time I plan on trimming and backfilling my position as the price moves around. I last added 12% to my position at $47.56 in August and had the opportunity to part with 10% of the holding at $69.57 a few weeks ago. The core position remains.
With each cycle of the price the portfolio builds out a bit.
