At this current SP looks like a good buy given high probability of good sales news (read the last dozen announcements in succession). I am holding a parcel from 6c which taught me a good lesson (never chase a biotech speccie's SP spike), I have subsequently averaged down, still a small holding in my portfolio, I would never commit more than a fraction of my reserves in speccie bios (unlike say QBE etc.)
Personally I would have been stopped out long ago if my buy in was 20c, but if you're still holding, no point selling now (probably exactly what you're thinking).
