The performance of the fund should be the most important consideration. Investors can objectively evaluate the performance of the fund from the following four aspects: compare the performance of the fund with the established indicators. Overseas, when the fund is established, an indicator will be set to measure and evaluate the performance of the fund. The setting of this index is directly related to the investment target and operation style of the fund. For example, high-tech funds correspond to high-tech indexes, and small-scale funds correspond to small-scale fund indexes. If the performance of the fund is better than the index, the performance of the fund is worthy of recognition; Similar funds between large-cap funds and large-cap funds, between small-cap funds and small-cap funds, and between funds with the same investment target are comparable. It is unscientific to compare funds with different investment targets, operating styles and scales; Looking at the long-term performance of the fund from the perspective of long-term investment can reflect the overall performance of the fund. A fund's short-term net performance may be very poor, but from the long-term historical performance, if it is shared equally every year, the cumulative performance of the fund may be quite good.
