The new fund needs to be opened before it can be purchased and redeemed. The general time is 1-3 months, and the specific time has to wait for the announcement of the fund company, so it is impossible to predict in advance.
Bond funds, stock funds and money funds are based on the financial market in which the funds invest. Buying a fund should be based on the quality of the financial market in which the fund invests, not on the length of the fund's issuance. It has nothing to do with the issuance time of the fund.
