Nothing wrong with a good short. It takes balls to short a stock that they believe is overvalued and if they get it right they should be rewarded. Nothing sinister about it. At the end of the day there is just these three concepts:
-Overvalued
-Fairly valued
-Undervalued

I've shorted commodities, currencies and stocks. Having said that, shorting APT seems super risky since it has so much upside (but maybe I'm bias as a long term holder).
