1. In terms of stock suspension, the simple point is that some listed companies have illegal behaviors, which were detected by the stock exchange and then suspended. During the period of stock suspension, it is necessary to actively cooperate with the investigation of the stock exchange and seriously investigate the financial situation and ownership structure changes of the listed company corresponding to the stock. It is difficult to determine the time of stock suspension, mainly depending on what causes the suspension. If the reason for suspension disappears, the stock exchange may resume trading and issue relevant announcements. If the pause is serious, special handling may be required.
2. When a listed company publishes important information such as performance reports, dividends, mergers and acquisitions, and changes in equity, it may suspend trading. Securities regulatory authorities believe that listed companies need to clarify and announce matters that have a significant impact on the company. Listed companies are investigated for violations, and the suspension time needs to be decided according to the progress of the matter. The reason why the exchange suspends the trading of listed companies is to solve the problem of asymmetric information of investors. By suspending trading, the abnormal fluctuation of stock price can be prevented, thus protecting the rights and interests of investors. It also highlights the suspension of abnormal warnings such as untimely information disclosure of listed companies, suspected violations of laws and regulations, and stock price changes. After the suspension of trading, it is confirmed that the listed company has fully, accurately and completely disclosed the information about the significant impact as required, and the shares of the listed company can be resumed.
