If the purchased fund falls, the principal will not be deducted from the card after deduction. When the stock fund purchased by investors plummets, the damage caused by the decline will only be deducted from the principal. Under normal circumstances, it is not easy for investors to fully deduct the principal. When the net value of the fund falls to a certain level, the fund company will carry out settlement operations, calculate the total market value of the investor's stock fund according to the net value of the fund at the time of settlement, and then return it to investors.
