Daily fluctuation = (net fund value of the day-net fund value of the previous trading day)/net fund value of the previous trading day.

For example, the net value of the fund on that day was 1. 1035, and that on 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, and the net value of the fund on the previous trading day is 1. 1228.

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

Hope to adopt. Thank you.
