Daily fluctuation refers to the fluctuation range of a day, expressed as a percentage. For example, the fund's daily increase of 2% means an increase of 2 percentage points over the previous trading day. Daily ups and downs refer to how much a stock (or market) has risen (if it is a market unit, it is points), and the unit is yuan (or points), while the ups and downs are the ratio of the number of ups and downs of the day to the closing price of the previous day, calculated as a percentage (both stocks and markets are percentages), and there is no unit.

The object of fund allocation is net income, that is, the balance of fund income after deducting expenses that should be deducted according to relevant regulations. The expenses mentioned here generally include: management fees paid to fund management companies, custody fees paid to custodians, fees paid to certified public accountants and lawyers, and start-up expenses incurred when the fund is established. Generally speaking, the net income of the fund in that year must make up for the loss of the previous year before the income distribution of that year can be carried out; If the fund has a net loss in the current year, it should not distribute the income. Whether it is a closed-end fund or an open-end fund, the object of income distribution is the investors who hold fund shares on a specific day. Fund management companies usually need to designate the last date of record to get the right of income distribution, and all investors listed in the register of fund holders will have the right to enjoy the income distribution after the transaction ends on this day.
