Monetary funds, like non-monetary funds, are essentially net worth. In terms of expression, non-monetary funds are expressed in the form of unit net value (or "share net value"), that is, the net value of one fund share. Customers only need to multiply the number of shares held by this unit net value. You can get the fund value of its holdings (for example, if a customer holds 10,000 shares of a fund and the net unit value of the fund is 1.2100 yuan, then the customer holds the fund value of 12,100 yuan); the monetary fund is based on the income per 10,000 shares and It is expressed in the form of seven-day annualized rate of return. Since the net value of a currency fund unit is constant at 1.0000 yuan, the return per 10,000 shares means the income that can be obtained by investing 100 million yuan (10,000 shares * 1.0000 yuan/share), and the seven-day annualized rate of return is The daily annualized rate of return is the geometric average of the rate of return in the last seven days and then annualized. The formula is:

Step 1: Calculate the geometric mean of the rate of return in the last seven days G7=(1+ R1) (1+R2) (1+R3) (1+R4) (1+R5) (1+R6) (1+R7)^(1/7)-1;

Second Step: Annualize the above geometric mean R=(G7+1)^365.

After combining the above formulas, it is:

R = (1+R1) (1+R2) (1+R3) (1+R4) (1+R5) (1+ R6) (1+R7)^(365/7)-1.
