In order to effectively measure the performance of the fund, it is necessary to comprehensively consider the investment objectives, risk level, comparison benchmark, period selection and the stability of the fund portfolio. Commonly used indicators to measure income mainly include net growth rate, annualized rate of return, seven-day annualized rate of return, daily net income of 10,000 shares, risk-adjusted income and other indicators, among which the seven-day annualized rate of return and daily net income of 10,000 shares are used to measure the income of the money fund. Sharp index and Stutzer index are commonly used to measure risk-adjusted returns. Sharp index refers to the ratio of the return of a portfolio that exceeds the risk-free interest rate to the standard deviation of the return of the portfolio in a certain period. Sharp index takes standard deviation as the measure of fund risk, and gives the excess return of standard deviation of fund share. The greater the Sharp index, the better the performance. Stutzer index is a correction index to Sharp index.
