MSB is biggest in my portfolio for punting. Lost 33% as of now. The only hope now is covid results. Back pain- several treatments existing and emerging and so physicians unlikely to go for this very expensive option. CHD sounds promising but I wonder if trial results are inconclusive as they have been sitting on it for a while with completion goal posts have been moved constantly. I thought of selling half my parcel but the only thing that kept me away was going to the MSB website and reading up on the credentials of their executive team and board. Ive never seen such an accomplished group of people in a company and so I'll hold till the end... Time will tell if its the right decision or not but Im hopeful they will work something out..
