The difference between fixed investment and non-fixed investment when buying funds is as follows: 1. Fixed investment is a long-term investment. By continuously increasing the holding share, the cost of holding the position is shared and the risk is dispersed. Investors do not need to care about the time of entry or the market price.

A one-time purchase requires investors to find the best buying time based on the trend of the fund's net value and other factors.

2. When running fixed investment funds, investors only need to set the time and amount of each fixed investment when purchasing the fund for the first time, and ensure that the bank card has sufficient funds. It will automatically purchase and deduct money, without the need for investors.

Manual purchase each time saves time and effort compared with one-time purchase.

3. Compared with fixed investment in a fund and one-time purchase, the expected return from fixed investment is the compound interest effect. The interest generated from the principal is added to the principal to continue to derive the expected return. Through the effect of interest compounding, as time goes by, the compound interest effect becomes more obvious.
