A decline in the fund's net value is a loss. The net value of the fund is the same as the stock price. A decline in net worth is equivalent to a decline in stock prices and a decline in net worth. Investors must have lost money. But the final profit and loss depends on whether the net selling value is greater than the net buying value. If it is greater than the net purchase value, it will be profitable.

The net value of a fund unit refers to the value of each fund and is an indicator to measure the value of the fund. Net value of fund unit = total net asset value of fund/total share of fund unit, and the subscription and redemption of open-end funds are carried out at this price.
