The calculation method of fund net value growth is not based on the net value at the beginning and end of the period like you.
Why?
For example, the net value of a fund today is 1 yuan. If it paid dividends to 0.5 yuan last month, it is not accurate to use 1 yuan as the base of the current rise and fall. So, calculate the net value.
The re-weighted value of fund net value refers to the re-weighted calculation of fund unit net value, and comprehensively considers the dividend or split factors of the fund to calculate the historical net value of the fund without any dividend or split, so as to restore the fund net value.
If there is no dividend among a fund, then its calculation can be calculated like that of the landlord.
If there is no dividend, its calculation formula can be simplified as:
Growth rate of net unit value = net unit value at the end of the period-net unit value at the beginning ÷ net unit value at the beginning.
If there is a dividend in the middle, the calculation formula is: the growth rate of the net asset value of the current fund = the net asset value of the current fund before the first dividend ÷ the net asset value of the current fund before the second dividend ÷ the net asset value of the current fund after the first dividend × the net asset value of the current fund after the last dividend.
The period mentioned here is the period you calculated, for example, this year is from 20 13 1 month 1 day to the present.
For example, on June 38, 2007, the unit net value of a fund was 1.5 yuan+10/and on September 30, it was still 1. 5 yuan, but there were two dividends in the middle, namely on March 3 and May 30, and the dividend ratio was/kloc-0.
Then the net growth rate from June to September 2007 is calculated as follows:
=(2÷ 1.5)×[2.5÷(2-0.5)]×[ 1.5÷(2.5-0.3)]- 1
=0.52
Therefore, the fund's net growth rate this month is 52%.
The calculation method you said should be:
( 1. 1720÷ 1. 1440)×[ 1. 1650÷( 1. 1720-0.03)]- 1≈0.043
1. 1720 is the net value of Efund enhanced bond A 1. 17 before dividends, and 1. 1440 is the net value after dividends. 1. 1650 is the latest net value.
I hope I can help you!
