Protect the interests of investors. When the market is good, a large number of investors subscribe, and the fund manager who subscribes for the fund cannot invest in time to generate income, which will dilute the interest of the original investors.
Maintain a stable scale to facilitate the operation of fund managers. The large change of fund scale is not conducive to the investment of fund managers. Fund managers have to significantly reduce and increase their positions, which may cause significant fluctuations in fund performance.
