The lower the cost price of the fund, the better. The lower the cost price, the lower the risk that investors take and the higher the probability of earning in the future. On the contrary, the higher the cost price, the greater the risk that investors take and the greater the probability of future losses.

The fund cost price is obtained by adding the fund handling fee to the net value when purchasing the fund, and the calculation formula is = {(net value of fund purchase * fund share)-handling fee}/fund share. When the cost price of investors' positions is too high, investors can increase their positions when the fund falls to reduce the cost.
