When the net value of the parent fund rises to a certain threshold (generally agreed as 1.5 yuan or 2 yuan), in order to cash in the B share, the part with the net value of the B share greater than 1 yuan will be returned to the investors in the form of the parent fund, so as to realize the income distribution of the B share.

Buy a B-class fund that falls below the discount threshold. "For B-share holders, once the graded funds are discounted, the losses will be very heavy. Since the price of Grade B before conversion is much higher than the net value and the net value is less than or equal to 0.25 yuan, the grade B will be converted according to the net value on the conversion base date. In addition to the decline in Grade B, we also lose the difference between the price and the net value. "
