Fund investment must first adhere to the long-term investment concept. The characteristics of funds are collective investment and expert financial management, and excellent stock funds can often obtain income that is synchronous with or even beyond the market average. When there is a temporary decline in the market, the net value of the fund tends to shrink temporarily, and many investors stop fixed investment (or even redeem the fund) for fear of falling. In fact, as long as investors insist on the fixed investment of the fund, they will have the opportunity to buy more fund shares at a low level; If we persist for a long time, the average cost will naturally decrease, so that we are not afraid of the ups and downs of the market and finally get good returns. Make good use of partial termination and switch funds in time. After starting regular fixed investment, if you need to cancel the contract temporarily or the market is at a high point, you are not sure about the market outlook, you don't have to cancel the contract completely, and you can redeem some shares to obtain funds. If the market trend changes, you can switch to another round of rising prices and continue to make regular fixed investment. Trust the experts. When you start regular fixed investment, you don't have to care too much about short-term ups and downs and share accumulation. If necessary, you can consult experts.
