Money fund refers to an investment fund that invests in short-term (within one year, with an average term of 120 days) securities in the money market. The assets of the Fund are mainly invested in short-term monetary instruments, such as treasury bills, commercial paper, bank time deposit certificates, government short-term bonds, corporate bonds and other short-term securities. Money market funds have the characteristics of stable income, strong liquidity, low subscription limit and high capital security.

However, it takes 2~4 working days for domestic general money funds to submit redemption applications and receive them. Some investors are worried that they can't withdraw cash when they are in urgent need, and nearly 40 trillion residents' demand deposit funds can only be idle in their accounts. The "Monetary Fund T+0" refers to the redemption application submitted by the Monetary Fund, and the funds will even arrive in real time on the same day. Realizing "money fund T+0" means that money funds with income comparable to time deposits will get the same liquidity as demand deposits. The realization of "monetary fund T+0" is of great significance to the daily cash management of ordinary investors. There is little difference between several money funds. In terms of income, 5 19888 is relatively stable, 5 19898 is erratic, and 5 19800 is slightly lower.

Specific operation, I suggest you first see if your broker does not charge commission, if so, then give up decisively.

Others can be added to the optional list, because there is a daily subscription limit, so you don't have to buy it if you want, so if you find that you can't buy it, you can change it quickly.
