Under normal circumstances, the net value of the fund can be adjusted artificially. For example, after the fund pays dividends to shareholders, the net value of the fund will decrease accordingly. In the actual operation process, the fund can also adjust the increase or decrease speed of the fund's net value through the increase or decrease of its own position. When the fund's position increases, the net value of the fund will change faster. When the fund position decreases, the change of fund net value will also slow down accordingly.
