How to treat the performance of the fund? Regular fixed investment can be understood as "agreed time, agreed deduction amount and automatic deduction investment". Regular fixed subscription business refers to a trading method in which investors apply for deduction and subscription at a fixed date and amount through designated sales organizations, and the designated sales organizations automatically complete the deduction and fund subscription application for investors on the agreed deduction date. Whether it is pre-stored or renewed monthly, it is only necessary to ensure that the account has enough funds when deducting money. The ultimate goal of the fund is to make money for investors, and performance is of course important. We can judge the fund management level of a fund company by paying attention to the ranking of its funds among similar funds in the same industry.

It should be reminded that investors often judge the quality of funds by their short-term performance, which is actually wrong. Paying attention to long-term performance and the stability of performance is the most objective criterion for evaluating the quality of funds. If we only take the short-term performance of the fund as a reference, high-quality funds may be ignored because of poor short-term performance.
