The page says "...the best strategy... is a portfolio of one out-of-the-money call and one out-of-the-money put." I think this should say "one written out-of-the-money call and one written out-of-the-money put.

Normal distribution

"Herein lies the weakness of the Sharpe Ratio. Not all asset returns are normally distributed"

"I think this would be better stated thus: Asset returns are not normally distributed."

Normal distributions require events to be independent of each other. Asset trading (the "events" in this case) are not independent of each other. Buy and sell decisions are driven by the market price, which is in turn driven by individual trading decisions. They look like they are normally distributed, but they are not.
