If the cost price of fund positions is higher than the net value of the fund, it means that the fund is in a state of loss; If the cost price of fund positions is lower than the net value of the fund, it means that the fund is in a profitable state. Position cost price = position cost/position share, and fund net value is the total net assets representing each fund unit. The main factor affecting the position cost and the position cost price is the floating profit and loss of the fund. The more profits, the lower the position cost, the more losses and the higher the position cost.

How to reduce the fund's position cost According to the fund's price-earnings ratio, the fund's position cost should be reduced. When the P/E ratio of the fund is at the lowest in history, the fund should be fixed. If it is a fixed investment, it should continue to adhere to the fixed investment of the fund. When the P/E ratio of the fund is in the normal stage, you should continue to hold the fund. If the method of fixed fund investment is adopted, the fixed fund investment shall be stopped. When the P/E ratio of the fund is at a high level or the highest level in history, the fund should be sold decisively. Holding funds according to the P/E ratio can effectively reduce the cost of holding funds.
