The biggest feature of the fund's fixed investment is that it can diversify investment costs and market risks through long-term fixed investment, regardless of the choice of time points, thus enhancing long-term profit opportunities. The flexible form of the fund's fixed investment can avoid the psychological pressure of a single large investment. When the price goes up, the share of buying becomes less; When the price goes down, the buying share will naturally increase and accumulate for a long time, which can effectively reduce the investment cost and the risks brought by the market and easily face market fluctuations. Compared with the greater risks that may occur when a single investment fluctuates in the stock market, the fund's fixed investment effectively disperses market risks and better manages customer assets through the above methods.
