1, transaction cost
For example, redemption of funds will charge a certain redemption fee. When the profit of the position is less than the redemption fee, the investor's position will be profitable, but the funds actually received will be lost. The redemption rate is related to the holding time, that is, the shorter the holding time, the higher the redemption rate. If the holding time is less than seven days, it will be charged according to the standard of 1.5%.
2. The net value lags behind
The purchase and redemption of funds generally adopt the principle of unknown price, that is, the purchase and redemption are based on the net asset value of fund shares after the closing of the application date to calculate the amount of fund shares bought or sold. Announce the net asset value of the fund share the next day. Therefore, when investors buy and sell funds during the trading hours of the day, they only know the net asset value of the fund shares of the previous day, but do not know the exact price of the day's trading.
When the net value of the fund falls, and the net value of the fund displayed on that day is the last trading day, investors actually lose money by holding positions.
3, software problems.
Some trading software, after the close, will have some minor problems, resulting in investors clearly losing money that day, but the software shows profit. This situation will generally return to normal on the second trading day.
At the same time, the following situations will cause investors' funds to rise but their income to fall:
1. The net fund value has increased compared with the previous trading day, but it has decreased compared with the investor's position cost, that is, the net fund value is lower than the investor's position cost, and the income is negative.
2. When investors hold multiple funds, some funds rise and some funds plummet, then the loss is greater than the gain brought by the rise, and the final holding gain is negative.
In short, the ultimate profit and loss of investors is based on the redeemed funds.
