Hi all. I am interested in why so many people here are using Sharpe Ratio as a measure of their performance in options trading. It was my understanding that this performance measure is not appropriate when there is an asymetric distribution of returns... which by their very nature options will produce. This ratio can be very easily be manipulated by what strategy that you choose to follow... and certainly should not indicate one trader's superior perfomance to anothers. Thank-you for your replies.
