I don't know squat about greys but if it allowed the stock to be traded I am all for it as long as it is known that greys are a risk that typically never pans out. It sounds like it is.
In that case I see a buyer beware there, and that is really what this stock needs right now if we are going to let it trade. I'd sell if it went up a hair, held if it stayed, and yeah, I would even buy if it dropped. Because like newmedman says, the product hopefully will get a chance to speak for itself and I certainly have agreed to the potential this product does have. Unfortunately, due to legal issues, it may never get it's chance.
