The advantage of a large-scale fund is that the larger the fund is, the lower the handling fee and the lower the investment cost when sharing the fixed information disclosure fee, audit fee and attorney fee. The risk of liquidation is much lower when the fund is big. The disadvantage is that it is not conducive to fund managers to adjust positions, affecting the flexibility of operation, and may miss the opportunity to buy or even make some mistakes. Moreover, it is not necessarily possible to buy some tickets with small market value on a large scale, and it is of little significance to buy only a few scattered tickets.

The advantages of small funds are convenient and flexible position adjustment, small ships can turn around easily, can adapt to the changing market and respond quickly to the market; Playing new income is more obvious, because there is a bottleneck in the contribution of playing new income offline, so when the fund management scale is small, playing new income offline can significantly improve the fund income. The disadvantage is that the small-scale fund has the risk of liquidation, and the large-scale fund company may cause the cost to exceed the income, so it simply enters liquidation and does not operate. In addition, when the cost of the fund is allocated to the unit share in the operation process, the smaller the scale, the greater the corresponding allocation ratio and the greater the investment cost.

Under normal circumstances, it is better for money funds and index stock funds to be larger, because the impact of redemption will be smaller.
