The income of the parent fund is related to the income of the AB share, that is to say, the net value of the parent fund split into two types of shares = the net value of the A type sub-base X A share%+the net value of the B type sub-base X B share%. If the shares of A and B are equal, then the net value of the parent fund is the average of the net values of A and B. ..
Where share A is agreed income, which is equivalent to fixed income,
B shares are market gains.
When the market rises, share B will appreciate faster after bearing the income of share A; Therefore, when the market falls, B's share falls first.
That is to say, the parent fund neutralizes the conservatism of A and the radicalism of B.
