Yes, but the weekend is a non-trading day, and investors can entrust it, but they won't make a deal. The index funds bought at the weekend will be calculated at the net value at the close of next Monday, and the share will be confirmed on the second trading day.

The index funds in the market are all bought on weekends, and the trading day is valid, so they may not be able to clinch a deal. Index funds in the market, like stocks, trade according to real-time market prices and follow the principle of price priority and time priority.
