书上202页说,sharp ratio is another option to evaluate hedge fund manager performance. 我的理解是SHARP RATIO IS UNDER normal distribution assumption, 不适合用在有OPTIONS 的 情况下。 所以,我觉得SHARP RATIO 是不能用来EVALUATE HEDGE FUND.
I think it is mentioned somewhere in notes that Sharpe ratio may not be the best way to evaluate HF returns due to its normal distribution assumption, but it will still give you a sense as for how the fund performs and you can always use other measures to complement.
