You can choose on-site subscription and redemption (opening trading account-stock-on-site fund-on-site subscription and redemption). According to the redemption method of ordinary open-end funds, it is the same day only if it is submitted before 15, or you can choose to split the parent share into two parts, A and B (trading account-stock-fund split after the market opens). Fund split, also known as split fund, refers to a way to change the corresponding relationship between the net value of fund shares and the total amount of fund shares and recalculate the fund assets on the premise of keeping the total assets of fund investors unchanged. After the fund is split, the original portfolio remains unchanged, the fund manager remains unchanged, the fund share increases, and the net value of unit share decreases. The split of fund shares can reduce the net value of fund shares by directly adjusting the number of fund shares, without affecting the realized income, unrealized income and paid-in fund.
