It is more important to buy a fund to see performance than net worth. Looking at the performance of the fund also depends on the type of fund. Different funds choose different frames of reference. Bond funds can only be compared with bond funds; Hybrid funds depend on the ratio of stock to debt; Stock funds can be divided into active and passive types, with the same frame of reference, but different evaluation criteria; QDII should be compared with the stock market in the investment area.
In short, the performance of the fund is not simply to see how awesome it is, but to compare it with the reference system of the fund.
