A: According to the requirements of the CSRC, the calculation formula of the fund's net growth rate is: today's net growth rate = (today's net value-yesterday's net value)/yesterday's net growth rate = [today's net value-(yesterday's net value-dividend)]/(yesterday's net value-dividend). The net value used in the above calculation is the current net value, not the accumulated net value. If the cumulative net value is used to calculate, the trouble of dividend treatment can be avoided, but the calculation result has certain error with the above standard result. Galaxy Securities Fund Research Center's net fund growth rate is calculated in strict accordance with the standards of China Securities Regulatory Commission, and has been tested by fund companies and fund investors every day for five years. It is one of the most accurate and comprehensive fund performance tracking data in China at present, and investors can use it with confidence.
