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. People usually refer to funds mainly as securities investment funds. It has no limits. You can throw more, throw less, or interrupt.

Generally speaking, there are two ways of fund investment, single investment and regular quota. Because of the low starting point and simple method, the fund is also called "small investment plan" or "lazy financial management"

"Compared with fixed investment, the one-time investment income may be high, but the risk is also great. Because it avoids the influence of investors' subjective judgment on the timing of entry, the risk of fixed investment is significantly lower than that of stock investment or single fund investment.

The fixed investment of the fund is similar to long-term savings, which can spread the investment cost evenly and reduce the overall risk. It has the function of automatic bargain-hunting plus code and bargain-hunting minus code. No matter how the market price changes, it can always get a lower average cost.

Regular fixed investment can smooth the peaks and valleys of fund net value and eliminate market fluctuation. As long as the selected funds grow as a whole, investors will get relatively average returns without worrying about the timing of entering the market.
