The principal Swiss equities venue, home to a concentrated set of large-capitalisation pharmaceutical, food, and financial issuers. Swiss confidentiality norms and a granular disclosure regime make it a structurally favourable market for institutional collateralisation.
On SIX, an off-order-book block is reported on-exchange through the Two-sided Trade Report function, where the two participants each enter and reconcile the print; clearing and settlement then run T+2 through SIX SIS. The venue is concentrated in large-capitalisation SMI names, so a block is sized against the turnover of the individual line. Where the transfer crosses an Article 120 FMIA threshold, the parties’ notification duties to the issuer and the Disclosure Office are managed alongside the reporting.
What qualifies on SIX.
SIX ranks among the deepest equity pools anywhere; eligibility turns on the stock itself — its free float, daily traded volume, and how concentrated the line is.
For any given SIX position, our review looks at: free float and daily traded volume against the size of the transaction; your status (controlling shareholder, director, substantial shareholder) and the disclosure that follows; the issuer’s sector and listing segment; and what the transaction must do (LTV, tenor, currency, recourse, custody).
Framework cited on SIX.
The principal regulatory reference on SIX is FMIA Art. 120. How it applies to any single transaction — reporting levels, step thresholds — turns on the underlying rules and national-law overlays, which we map against your contemplated transaction at the structuring stage alongside the counsel you appoint.

What Is a Block Trade, and How Does One Work?
A block trade is the off-market sale of a large line of listed shares at a negotiated price, executed bilaterally and printed under exchange rules to avoid moving the open market.

A large block is sold without moving the price by taking it off the open order book — negotiating off-market at an agreed price, often with a liquidity provider taking the risk, and printing under exchange block rules.
Read → DisclosureDo Block Trades Have to Be Disclosed?
Often yes. Once a significant shareholder crosses a market’s substantial-holding threshold, a block sale is generally notifiable to the regulator within a set window, with thresholds varying by jurisdiction.
