I'll take a shot at this one in Phantom's absence.
Marker tech is similar, but not the same as CAR-T. It is Multi-Antigen Targeted Cell Therapy. Much less toxic and more effective with no relapse in disease(so far). More details in link below:
Yesterday's drop, imo, was from normal trading patterns as it went up very fast in a short time. We're still up from last Friday's close. I was expecting a little drop yesterday from the $12's... was very surprised it shot up to $13. I still think we're right on course to $20's in the near future.
