Swiss Listed Shares

SIX is the reference market for over 250 Swiss shares, consistently offering the best prices and the narrowest spreads in combination with the largest volumes.

Swiss Listed Shares are traded across 2 order books on the Swiss stock exchange: the Central Limit Order Book (CLOB) and SwissAtMid. With a single order, participants can access both liquidity pools.

Maximizing Liquidity

The simultaneous execution across the three distinct order books maximizes the liquidity an order can interact with and ensures participants are always obtaining the best available price on SIX for their limit order.

The Central Limit Order Book (CLOB)

The CLOB is the main source of liquidity. It operates in continuous trading and runs both the opening and closing auctions for all the Swiss listed instruments. Find out more.
