"There are many indicators to measure the calculation of money fund income, which represent different meanings: 1, fund daily income: refers to the daily income per 10,000 fund shares on the announcement date; 2. Seven-day return rate of the fund: refers to the annual return rate of assets converted from the income in the last seven days (including holidays); 3. Fund's return rate in the last 30 days: refers to the annual return rate of assets converted from income in the last 30 days (including holidays); 4. Fund's annual rate of return: refers to the annual rate of return of assets converted from all income this year; 5. Rate of return since the establishment of the fund: refers to the annual rate of return of assets converted from all income since the establishment of the fund. There are usually two indicators to reflect the rate of return of commodity market funds: one is the seven-day annualized rate of return; The second is the income per 10,000 fund units. "

Xiao Zhang asked Sister Li again: "Is there a difference between the income converted from the last seven days to the return on adult assets and the income per 10,000 fund units?"

Sister Li replied: "The unit net value of the money fund is always 1 yuan, and there is income distribution every day. When there are fluctuations, every day is different. The income per 10,000 fund units is the actual income you get every day. For example, "On May 4, 20 12, the income per 10,000 fund shares of Guangfa Currency B 1.2504" means that the income per 10,000 fund shares today can be 1.2504 yuan. Seven-day annualized rate of return is the rate of return converted from the average income of the last seven days to one year. It is to examine the long-term profitability of a monetary fund. "

Xiao Zhang asked: "In the calculation of monetary fund income, how to calculate the annualized rate of return on seven days?

Li Jie: "Seven-day annualized rate of return = ((∑ Ri/7) × 365)/1000×100%, in which RI is the daily income of the fund on the latest ith calendar day (I = 1, 2...7), and the seven-day annualized rate of return of the fund. A simple understanding is to add up the 7-day rate of return, then calculate the average daily rate of return, and then multiply it by 365 or 360 days to calculate the annual rate of return. This is called annualized rate of return. For example, the annualized rate of return of a money fund on the same day is 4.58%, and assuming that the income of the money market fund in the next year remains unchanged from the previous seven days, if it is held for one year, it can get the overall income of 4.58%. Of course, the daily income of money market funds will constantly change with the operation of fund managers and the fluctuation of money market interest rates, so it is unlikely that the fund income will remain unchanged for one year in actual operation. Therefore, the seven-day annualized rate of return can only be used as a short-term indicator and cannot represent the actual annual income of money market funds. "
