Fund share × fund net value = fund amount, which can be converted according to this formula. Generally speaking, investors do not need to switch. When investors buy a fund, they buy the net value, that is, "how much is a fund". For example, the net value of the fund is 2 yuan, and at this time it is 2 yuan. If the investor has 1000 yuan, he can buy 500 funds (excluding the subscription fee).

Share redemption is adopted when selling the fund, that is, the total redemption amount is equal to the redemption share multiplied by the net value of the day.
