Hello, Article 3. 1.4 of the Trading Rules of Shenzhen Stock Exchange (2065438+revised in September 2006) stipulates that the securities bought by investors shall not be sold before delivery, except for circular trading. Securities circular trading refers to the securities bought by investors, which are sold in whole or in part after the transaction is confirmed and before the settlement is completed.

Bonds, bond-trading open-end funds, gold-trading open-end funds, listed money market funds, cross-border trading open-end funds and cross-border listed open-end funds are traded on the same day, and B shares are traded on the next trading day.

Cross-border traded open-end funds and cross-border listed open-end funds mentioned in the preceding paragraph are limited to the tracked index component securities or open-end funds that are circulating on the day when the investment target is implemented. With the approval of China Securities Regulatory Commission, the Exchange may adjust the types and methods of circulating securities.
