Companies may hold a primary or secondary listing, and an issuer can open a second order book under its own security number to run a separate trading line. The exchange added the Auction Volume Discovery order type with release SMR11 on 15 May 2023, letting participants take auction liquidity without moving the uncross price. Sparks, the segment for smaller companies, runs an opening auction at 09:00 CET, continuous trading to 17:20 CET, then a closing auction and Trading at Last to 17:40 CET.
Sparks is a full listing, not a lighter regime, and its entry tests are explicit. A candidate needs a market capitalisation below CHF 500 million, a track record over 2 years, more than 50 investors, equity capital above CHF 12.0 million, a capital increase above CHF 8.0 million at the IPO unless equity capital already exceeds CHF 25.0 million, free float above 15 per cent of shares outstanding and free float market capitalisation above CHF 15 million. An issuer whose average market capitalisation passes CHF 1 bn over 12 months must move to the main market.

Debt is the quieter and more international half of the market. Around 3,000 bonds from over 580 issuers are listed, in all major currencies, with issue sizes that average CHF 200-250 million. In 2025 the exchange recorded 558 bond listings, up 18 per cent on 2024, and a listed volume of CHF 124 billion, up 15 per cent.
