I am and I own it. I just did my end of day look at my stocks and was wondering why MRKR suddenly got a close to 10% bump. While I'm pleased of course I'm also disconcerted that a Seeking Alpha article written by an amateur can have this result.
I've done extensive work on CAR-T cells, almost from the beginning, and this technology is extraordinarily impressive. My thought is that it is a prime candidate for a very early takeout, probably at a high premium since it is so cheap right now.
Also I'd say that if you are going to take a larger position, do so before the pancreatic data at ASCO.
