Is it serious to receive the warning of securities short message?

Nothing serious. It is not serious to receive the warning of securities short message. Securities short message reminder is an automatic risk reminder of the software system of securities companies, and it is also an automatic reminder of holding stocks. It is normal for securities companies to issue risk warnings, so it is not serious. For example, on the day of the listing of new shares and bonds, brokers will inform the new shares and bonds to be listed by SMS before the opening, and remind them of the risks.
