It is not necessarily good for funds to buy with low net worth. The net value is obtained by dividing the total assets of the fund by the total share of the fund. Generally speaking, a well-run fund has a high net worth and a bad fund has a low net worth.

Buying a fund should be considered from many aspects, such as the performance of the fund manager, the past performance of the fund, the size of the fund and so on. Don't just consider the net value of the fund. In the long run, the change of fund net value is unpredictable, and it may go up and down, which cannot be used as the only criterion for buying funds.
