The net value of open-end funds is updated every day, but the update time is generally after 22:00 that night. Some foundations will announce their net fund value around 16:00 at the earliest. Therefore, the net value of the fund seen by investors during the day is the net value of the previous trading day, and it is possible to see the real-time net value of the day after 22:00 at night. Understanding this mechanism of updating fund net value will help investors understand the calculation method of fund net value when purchasing and redeeming funds.
Whether the fund is purchased or redeemed, it is calculated on the basis of T-day net value, that is, the fund is purchased or redeemed on T-day, and the fund confirmation unit calculates the T-day net value on the basis of T-day net value. The definition standard of T-day is that before the trading day of 15:00, when the net value of the fund has not been updated, investors purchase and redeem the fund according to the principle that the price is unknown. When we redeem the fund, we can't directly redeem the amount, but redeem the fund share, and the redemption amount can only be the next sum after applying for redemption.
So I advised him that novices should be more exposed to A shares, Hong Kong stocks and US stocks, each with its own characteristics, but all investments have certain skills and methods, and there are many practical financial management tools. After all, investors, especially entry-level fund investors, only need to learn how to invest, master skills and master the use of financial instruments. They don't need to study whether the fund will be profitable in the long run, only need to worry about whether it will be profitable now.
The above questions are my personal thoughts. If you have other ideas, you can comment or discuss them below.
