Daily increase or decrease = (net fund value of the day-net fund value of the previous trading day)/net fund value of the previous trading day.

Example: the net value of the fund on that day was 1. 1035. The net value of the fund in the previous trading day was 1.0892.

Daily increase = (1.1035-1.0892)/1.0892 =1.3129%.

If the net value of the fund on that day is 1. 1035. The net fund value of the previous trading day was 1. 1228.

Daily decline = (1.1035-1.1228)/1.1228 =-1.71.

Similarly: weekly increase and decrease = (net fund value on the last trading day of the week-net fund value on the first trading day of the week)/net fund value on the first trading day of the week.

1. Pay attention to the proportion of fund types according to your risk tolerance and investment purpose. Choose the fund that suits you best, and set an investment ceiling when buying partial stock funds.

Be careful not to buy the wrong "fund". The popularity of funds has led to some fake and shoddy products "fishing in troubled waters", so we should pay attention to identification.

3. Pay attention to the later maintenance of your account. Although the fund is worry-free, it should not be left unattended. Always pay attention to the new announcements on the fund website, so as to have a more comprehensive and timely understanding of the funds you hold.

4. Pay attention to buying funds and don't care too much about the net value of funds. In fact, the fund's income is only related to the net growth rate. As long as the fund's net growth rate stays ahead, the income will naturally be high.
