Shorting a security is as sound an investment strategy as being long. I read a white paper written by renown PH.d, Susan Trimbath entitled "Why investors hate folks who short stocks" I spend quite a bit of time in AC. and Vegas playing Craps, some times I play against the house (PASS) and sometimes I will play with the house (DONT PASS) if I feel the table is cold.
Most folks think that investors who short stocks are out to hurt them??? Sorry, I just don't get it.
