The trading of open-end funds, that is, subscription, subscription and redemption, is calculated by the net value of fund shares. In fact, open-end funds are traded according to the net value of fund shares plus or minus a certain fee (subscription fee and redemption fee). After the close of each trading day, the fund management company will calculate the net fund share value of the day it manages, and after checking with the net fund share value calculated by the fund custodian bank, it will be announced to the public through the fund management company, exchange or other financial websites. So as long as you check the relevant websites or call the fund management company directly, you can check the daily net value of the fund.

However, it should be noted that the fund transaction adopts the principle of "unknown price", that is, if an open-end fund is purchased or redeemed during today's trading hours, the number of shares to be purchased or redeemed is calculated based on the net value of fund shares calculated after the closing of the stock exchange today, which will be announced the next day, so the net value of fund shares seen during the open-end fund transaction is the net value of the previous day.
