The principle of fixed investment is to avoid short-term fluctuation risk with long-term sustained and stable investment, so as to obtain the average rate of return of long-term income of the fund.

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 automatically increasing the price and reducing the price on dips. No matter how the market price changes, it can always get a relatively low average cost. Therefore, regular fixed investment can smooth the peaks and valleys of the fund's net value and eliminate market fluctuations. 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.

Funds are the best choice to pursue long-term benefits. If it is a fixed investment, it can also smooth out the loss of income caused by short-term fluctuations. Since it is the pursuit of long-term returns, you can choose the variety with the highest target returns, index funds. Index funds have optimized their targets. Blue-chip stocks and high-quality stocks in the industry, as representatives of models, have avoided the risks of individual stocks because there are a certain number of models. And avoid the impact of the economic cycle on individual industries. Because it is a long-term fixed investment, it takes time to digest the inevitable high-risk characteristics of high-yield varieties.

Recently, the market has proved that in the long run, the fixed investment index foundation earns more.
