Index fund is a kind of fund product with the purpose of following an index, and its trading and price are affected by the market, so there is no separate provision for closing the market. The trading hours of ordinary index funds are the same as those of stocks, that is, from 9:30 am to 3:00 pm from Monday to Friday. Although the fund will not be closed, the stock market cannot be traded during the closing period.

In China, index funds do not have separate trading hours, but are traded and priced together with stocks at the same time. Different index funds have different trading cycles. For example, the trading time of the Stock Connect Index Fund and the CSI 300 Index Fund is T+0, which means it will take effect on the day of subscription. The trading time of Yin Hua CSI 500ETF is T+ 1, which means that it will not take effect until the next trading day on the day of subscription.

Although there is no separate regulation on the closure of index funds, the exchange may suspend the trading of index funds when extreme market conditions and special events occur. For example, in the March 2020 stock market crash, the Chinese mainland stock market was suspended for 65,438+05 minutes to prevent the market panic from triggering a chain reaction. In this case, index funds cannot trade and are suspended from trading until the market reopens.
