Fixed investment is the abbreviation of fixed-term investment fund, which refers to investing a fixed amount (such as 500 yuan) in a designated open-end fund at a fixed time (such as the 8th of each month), similar to the bank's deposit and withdrawal method.

The fixed investment of the fund can effectively avoid market risks, because the share of purchase is different when falling and rising, and the risk can be shared equally.

For the principal, this concept, the principal of fixed investment is the amount you invest every month. There are no requirements. However, at present, the minimum fund is 100 yuan a month, and the average fund is 100 yuan a month.

As long as the fund company does not close down and the fund is not revoked, you can hold it for life.

How to do it: You can open a fund account on the website of a bank or fund company, and then choose which fund to invest in and the amount of investment. You can use the fund account to check the bill on the website of the fund company.

How to choose a fund is explained in detail in my other answers.
