Theres risks involved with everything in life... As TDA posted(great post by the way), all you can do is invest when you feel happy with the risk tolerance.
Myself...once Ive done the nessacary due dilligence, Im confident in my decision, and think of the glass as being more than half full!
Along with the product, trial success, management and how close we are to commercialisation...the small amount of shares on issue and the tightness with which these are held are also very pleasing to me.
Just wish I could buy more at these levels...
