1. When the fund has dividends, the maximum subscription amount can be set. Because dividend is to distribute a part of the fund's net value to investors, if you buy in large quantities at the time of dividend, the scale will expand rapidly, and if it is not handled well, it will dilute the interests of the original holders.

2. It is convenient for fund managers to operate. General restraining orders are mostly active funds, and the scale of funds is too large, which is not conducive to fund managers to adjust their positions and hold shares. If the fund is too large, it is difficult for the fund manager to manage it. When the scale of the fund is too large, when a single stock buys more than 5% of the market value, it will become the top ten shareholders of listed companies, and the top ten shareholders can't sell shares within six months, so it is difficult to exchange positions and shares.

3. Before the holiday. Funds that suspend subscription before holidays are usually monetary funds. Stock funds are closed on holidays, but money funds are still profitable, and investing in money funds has obviously become the first choice for many idle funds compared with the poor income from putting idle funds in current deposit accounts.

4. Closed-end funds, open-end funds in a closed period or funds open regularly. Closed-end funds, such products are designed to operate in a closed way to ensure that the scale remains unchanged and is not affected by daily redemption, so the subscription is suspended during the operation of the products.

Fund restriction on large subscription refers to the behavior that the cumulative subscription amount of a single fund account in a single day shall not exceed the prescribed amount. For example, if the single-day subscription amount is limited to 3 million yuan, then the investor's subscription amount on that day shall not exceed 3 million yuan.

Restricted purchase funds with more investment value:

First, understand the purpose of fund purchase restriction, because there are many reasons for fund purchase restriction, we can't directly invest in funds because of fund purchase restriction, so we should know the real reasons behind fund purchase restriction in detail.

Second, if it is a large-scale purchase restriction of excellent funds, we should still screen funds according to the usual process of understanding funds, make a comprehensive evaluation of funds, and understand the long-term and short-term performance of funds, the management ability of fund managers, the market environment and other factors.

Third, for restricted funds managed by different fund managers, priority can be given to funds with excellent historical performance, small-scale restricted funds and large-scale restricted funds.
