Introduction of the new trading segment “Structured Products with Extended Trading Hours” SIX Swiss Exchange AG is pleased to announce the introduction of the new trading segment for structured products with extended trading hours. From 1 December 2025, issuers of structured products will have the opportunity to trade their products either during regular trading hours from 9:15 am to 5:15 pm (CET) or from 8:00 am to 9:45 pm (CET). For this purpose, a new trading segment will be incorporated with almost identical functionality to the existing one.
In this way SIX Swiss Exchange AG is responding to a growing demand from private investors to be able to realize trading opportunities outside of the current trading hours.
