Filing a Complaint

The following information should be included in a written complaint so that we can properly and effectively address it:

  • Name of the party or parties involved;

  • Details of any alleged breaches of our rules, regulations or practices which undermine investor confidence in our markets;

  • Copies of any documents that provide evidence that supports the complaint; and

  • Name, mailing address, email address and telephone number of the complainant.

We require solid information on alleged wrongdoing before taking follow-up action. In addition, complainants should be prepared to answer follow-up questions from us. If we are not able to obtain the information we need, it creates difficulties for us to follow up on a complaint.

We discourage anonymous complaints or comments. Although anonymous complaints or comments will be noted, we may not be able to proceed with them further because we may need to contact the complainant to seek substantiation of the alleged matters.

We acknowledge receipt of complaints and review them for possible follow-up action. Complaints stemming from commercial disputes or containing elements of bad faith will not be pursued.

We are committed to dealing with complaints quickly. However, the period of time required for following up on the complaints depends on the circumstances of each case.

We will respond to your enquiries as soon as we can. Due to an overwhelming number of requests, we may not answer an enquiry if the answer is available on the HKEX website.  All enquiries and complaints are treated in strict confidence, however, if circumstances require, we may need to disclose information to relevant authorities, regulators or agencies for further follow-up. We will seek the enquirer’s and complainant's consent before disclosing any personal information.

The personal data collected is used to respond to your enquiries, complaints, comments and suggestions.
