The various CAR-T stocks have been discussed on the Biotech Values board (#board-1418), although more as long-term holdings rather than trades. See, for instance, #msg-110982416.
Patience me laddy... Cart T is gaining interest and is actually curing cancer, a major positive seems to be the T-Cell memory that is retained in the immune system. When we hit $400.00 then we'll have their attention.
