Alerts Regarding Unclear Information, etc.

TSE has a system for issuing alerts regarding information about securities or its issuers if it deems necessary to inform investors. In particular, TSE will issue an alert in the following situations where necessary.
・When unclear information (i.e., a leak or rumor) that is deemed likely to have material impact on investment decisions (hereinafter referred to as ""unclear information"") becomes available.
・When there are other circumstances regarding a security or its issuer deemed to require particular attention.

  • ・The system for issuing alerts is not a penalty or measure to ensure the effectiveness of the Regulations. It is aimed at allowing TSE to promptly and flexibly issue alerts regarding unclear information in cases where time may be required before appropriate information disclosure can be made or where only certain information can be disclosed immediately.
  • ・Under the system, an alert is issued each time TSE deems it necessary and is not removed. As such, multiple alerts may be issued for a single case on the day when the unclear information becomes available, and alerts may be issued on subsequent days for the same unclear information.
  • ・Decisions on whether to issue an alert are made separately from decisions on whether to halt trading.
