1, the reason why the fund has gone up but the income is negative: the rise and fall of the fund is only compared with the net value of the previous day, and the overall net value of the fund may be declining, and the fund needs to deduct the fund fee every day.

2. Fund expenses generally include two categories:

One is the expenses incurred by fund investors themselves in the process of fund sales, mainly including subscription fees, subscription fees, redemption fees, fund conversion fees, etc. These fees are generally charged directly when investors subscribe, purchase, redeem or convert. The subscription fee can be charged when investors buy funds, that is, the front-end subscription fee; It can also be charged when investors sell funds, that is, the back-end subscription fee, and its rate is generally decreasing according to the holding period.

The other category is the expenses incurred in the process of fund management, mainly including fund management fees, fund custody fees and information disclosure fees. These expenses are borne by the assets of the fund. For money market funds and some bond funds that do not charge subscription and redemption fees, a certain fee can also be extracted from the fund assets at a ratio of no more than 2.5‰, which is used exclusively for fund sales and services to fund holders.

3. The net value of a fund unit is the net asset value of each fund unit, which is equal to the balance of the total assets of the fund minus the total liabilities and then divided by the total number of unit shares issued by the fund.
