I was using Cellectis as an example of real threat to Kite, Juno if (big if) Cellectis works. I don't want to make it look like a recommendation for Cellectis.
I don't have any position in Kite, Juno either because of their valuation and it is not clear that it will work in solid tumor. Hematologic cancer is a very competitive market.
As for Cellectis, there is no data initially so I pass. After that one case was published, the stock jumped so I decided to pass.
My method of investing is to look for real positive data then wait until price drops for no good reason. Like now I loaded on FGEN (thanks to biomaven) and EGRX (thanks to Dew).
In my estimate EGRX can turn a profit this year rare for a biotech and nothing has changed since the stock peaked in Dec around $105. Below $70 yesterday, quite a bargain.
The market is not very rational or efficient (just like Dew signature)
