The expected return of the fund consists of two parts: the expected return of the dividend and the expected return of the bid-ask spread. Next, taking 1 yuan as an example, the specific calculation process of the expected return of the fund is introduced.
Take 1 yuan as an example to calculate the expected return. Suppose you buy a 1 yuan fund one day, the net settlement value of the fund on that day is 1.165, and the subscription rate is .5%, [1/(1+.5%)]/1.165]=854.98, so the fund share you hold is 854.98. During the period, the fund paid a dividend once, and each share of the fund paid a dividend of .14 yuan, which resulted in a dividend of .14*854.98=119.573 yuan. On the redemption day, the net value of the fund is 1.212, and the redemption rate is .4%, 854.98 * 1.212 * (1-.4%) = 1,31.26 yuan, so the expected return of the bid-ask difference is 31 yuan, and the expected return of the previous dividend is 15 yuan.
Conclusion: In fact, as long as you know the calculation method, it is very simple to calculate the expected return of the fund yourself. You can also try it yourself.
