The share ratio of A and B of stock-based graded funds is generally 1: 1. Most denominator funds are index funds that passively track an index.
The risk of graded fund A is lower than that of graded fund B, and the income is stable.
The net value relationship among the parent fund, Grade A and Grade B is as follows:
Net value of parent fund = net value of Class A sub-fund × proportion of Class A sub-fund+net value of Class B sub-fund × proportion of Class B sub-fund.
