SWX Swiss Block

SWX Swiss Block is a trading venue for Swiss blue-chip equities. It is part of the exchange infrastructure operated by SIX Group, the company that runs the Swiss and Spanish financial market infrastructures, including SIX Swiss Exchange and BME Exchange in Spain. SIX describes itself as the third-largest exchange group in Europe by free-float market capitalization, and its exchange services cover listing, trading and post-trading across the capital market value chain. Within that framework, SWX Swiss Block serves as a venue for trading blue-chip Swiss equities, complementing the main SIX Swiss Exchange order book. The SWX name is historically associated with the Swiss Exchange, which was originally known as the SWX Swiss Exchange. SWX Swiss Block is therefore best understood as a specialized trading facility or service brand within the broader SIX exchange ecosystem rather than a standalone company. SIX Group is owned by around 120 national and international financial institutions, which are both its owners and its main clients, a structure designed to ensure stability of the financial infrastructure and alignment with user needs. SIX provides exchange services, financial information and banking services, and operates in more than 50 countries for post-trade services. Its product portfolio includes market data, indices such as the SMI, SPI and SLI, reference data, regulatory services, and payments and banking services. The acquisition of UK-based Aquis in 2025 expanded SIX into a truly European exchange group with traditional primary exchange and multilateral trading facility (MTF) businesses across 16 markets including Switzerland, the EU and the UK. SWX Swiss Block sits within this broader European exchange group as a venue focused on Swiss blue-chip equities.

SWX Swiss Block is a trading venue for Swiss blue-chip equities. Its name references the SWX brand, which was historically used by the Swiss Exchange, the national stock exchange of Switzerland. The Swiss Exchange was originally known as the SWX Swiss Exchange and later rebranded as SIX Swiss Exchange following the restructuring of its parent company into SIX Group. SWX Swiss Block therefore represents a continuation of the SWX trading brand in a specialized form, focused on block trading or a distinct segment of Swiss blue-chip equities. SIX Group operates the infrastructure for the financial centers in Switzerland and Spain. It provides exchange services, financial information and banking services, and connects financial market participants in Switzerland, Spain and throughout the world. The company is owned by around 120 national and international financial institutions, which are its main users and clients. This ownership model is intended to guarantee stability of the financial infrastructure, proximity to clients' evolving business needs and competitive prices.

Within this group, SWX Swiss Block serves as a venue for Swiss blue-chip equities, complementing the main exchange order book and supporting the broader capital markets value chain.
