Kipk - the good reason, imo, is the God awful current environment we are in due to the uncertainties created by Covid-19. For those that have a glass half full view of life the current SP can also be viewed as being a tremendous buying opportunity, especially if one is prepared to wait longer. The history of ABL tells us that we are maybe 80% there with this drug but that it needs the other 20% to pay off.
In the months ahead the world will continue adapting to the huge monkey wrench that is Covid-19 and learn to live with what is now being termed as the 'new normal'. As that adjustment progresses I think that you will also see RVX start moving ahead again towards nailing down that last 20%. Yes, it likely will take another couple of years but life is what it is. We just have to roll with the punches. RVX is predominately still a private company with a few shares doled out to the public that has an restless and impatient fringe component within it. That being the case I don't get too hung up on the SP as being an accurate reflection of the company's worth.
