Compliant trading is a key factor in safeguarding the reputation of the Swiss Stock Exchange and the image as a financial centre. We surveil the Swiss Stock Exchange to ensure that any insider trading, price and market manipulation and other irregular activities and regulatory breaches are detected.
Market Surveillance and Investigations
We use innovative and first in class surveillance technologies to detect trading irregularities. Any indications of possible breaches are subject to in-depth analysis of the situation and further investigation, as needed. Our surveillance analysts also systematically investigate suspicions reported by third parties.
Audit of Participants
Participants directly connected to the Swiss Stock Exchange are required to submit an audit report. The audit relates to selected provisions of the rules and regulations, which stipulate that on-site monitoring must be performed. The participant audit may be conducted by external auditors or, under certain conditions, by the company’s internal audit department.
Pursuant to Section 19 of the SIX Swiss Exchange Ltd Trading Rules participants are required to submit an audit report from their external auditors to Surveillance & Enforcement. This report must cover compliance with selected provisions laid down by the rules and regulations of SIX Swiss Exchange Ltd. during the audited calendar year. The respective audit cycle is determined and communicated to the participants by Surveillance & Enforcement.
Participants who wish to commission the internal audit department to conduct the audit must submit a written request to Surveillance & Enforcement by 30 September of the respective year, including the required documents (for further information, please send an email to sveenc@six-group.com).
The requirements that must be met when conducting audit work, as well as further explanations, can be found in the Guidelines: Audit of participants.
The audit report for the 2025 calendar year must be submitted electronically in pdf-format to Surveillance & Enforcement by 31 March 2026 at sveenc@six-group.com. If an electronic submission is not possible, the audit report can still be sent by mail (SIX Exchange Regulation AG, Enforcement & Compliance, Hardturmstrasse 201, Postfach, CH-8021 Zurich).
