morel-san It's the return per unit of risk undertaken. It means that what ever amount you put into the mutual fund, you'll only be attributed a proportionate amount of risk. The more money is in the mutual fund, the higher your standard deviation and vice versa. It doesn't really matter what amount you put in actually.
morel-san They'll have the same Sharpe but their Standard deviation will be different
davidt87 morel-san, their std. dev. AND their return will be adjusted proportionally so that the Sharpe ratio is unaffected
