This conflates myriad issues. First, the business; second the science; and third those who are playing the game of buying/selling shares. It is hardly a novel idea that a poor business might find willing buyers of shares. For that I offer AMC & GME. It is also obvious that businesses can spend years trying to get traction before investors begin to realize the value of the company. For that I offer Apple and, if we want to remain in the pharma/biotech field, I offer Moderna and Alnylam. Anecdotally speaking.
Whether one wishes to acknowledge the science behind NWBO or not doesn't matter. The truth will speak for itself and will need no interpretation. As Yogi Berra might say, it ain't over for those deriding NWBO until the fat lady sings; but I think I hear her warming up in the background!
