First of all, if the fund scale is too large, it will be more difficult to manage the fund. Secondly, it is unreasonable for the fund to be too large or too small, generally between 2 billion and 8 billion.

If the scale of the fund is too small, the rise and fall of heavyweights will have a great impact on the performance of the fund, which will increase the risk of the fund. The small-scale fund will be greatly impacted by huge redemption, which is not conducive to the stability of the fund performance.
