Fund purchase restriction means that the fund has made a relatively big adjustment and set the upper limit of the subscription for the day. Therefore, when investors invest too much and reach this upper limit, the fund enters a suspension of subscription, and investors cannot invest at this time. Each fund product will set a minimum subscription amount and a large subscription ceiling, but the large subscription ceiling is generally high, and individual investors generally cannot reach the ceiling.

Fund purchase restrictions are generally due to:

1, protecting the rights and interests of investors.

When the fund market is good or when dividends are paid, many investors will rush to buy funds. If subscription is not restricted, the scale of funds will expand rapidly in a short time, and if it is not handled properly, the income of other investors will be diluted.

2. Control the fund size.

As the saying goes, "the boat is small and easy to turn around". When the fund scale is too large, the fund manager's ability to adjust positions and exchange shares is high. The fund manager needs to go through research and cannot buy or sell at will. If you buy in large quantities, you can only add positions, and the shareholding ratio will increase after adding positions, so we should consider the influence of the "Public Offering of Fund Double Ten" restriction.

3. Foreign exchange control. For example, QDII funds are mostly restricted by foreign exchange control.

4. Performance appraisal node. The fund ranks its performance every year. In the performance appraisal node, for reasons such as performance ranking assessment, fund managers may impose subscription restrictions to ensure their income, avoid diluting the holders' income, and effectively prevent excessive fluctuations in net worth.
