Funds in the same sector had better choose old funds. First, the old fund has no closed period, and investors can refer to the market to decide whether to buy. Secondly, the old fund can check the fund's heavy stocks and past performance, which has many reference factors for investors. Finally, the old fund has been running for some time and is relatively stable.

The new fund has a long opening period (about 6 months). When the fund goes public, the market situation is difficult to predict, and the new fund has no past performance as a reference, so there are many uncertainties. However, the new fund also has certain advantages. For example, the price of the new fund is relatively cheap, and the new fund can avoid risks. The new fund will be closed for three months. If the market is not good in these three months, the fund manager can choose not to open a position or to open a position in a small amount. During the closed period, the fund is not affected by market conditions, thus achieving the purpose of avoiding risks in disguise.
