02 · The Market
United Kingdom & Europe

Switzerland equity markets.

A Swiss block trade moves a large line of SIX-listed stock in a single negotiated transaction — off the order book, at an agreed price — so a holder can exit, or an acquirer build a position, without walking the screen. Black Haven can take the line onto its own book, giving the seller a clean, priced exit while the disclosure that follows a substantial transfer is managed around the print.

The Swiss market is concentrated in a small set of large-capitalisation names, so a block is measured against the daily turnover of that specific line rather than the market as a whole. Off-order-book trades between participants are reported on-exchange through SIX’s Two-sided Trade Report function, where each side enters and reconciles the print; settlement runs T+2 through SIX SIS. Where a transfer crosses an Article 120 FMIA threshold — 3% of voting rights and upward — the buyer, and often the seller, must notify the company and the Disclosure Office, so the reporting is planned before the line moves.

What holders ask about Switzerland.

01Does a block trade in Switzerland have to be disclosed?
The trade itself is reported on-exchange through SIX’s off-order-book reporting function. Separately, if the transfer takes a party across an Article 120 FMIA voting-rights threshold — starting at 3% for a Swiss-domiciled issuer — that party must notify the company and SIX’s Disclosure Office, generally within four trading days. We plan both the print and the notification before the line moves.
02How large a block can be placed without moving the price?
Because the transaction is negotiated off the order book at an agreed price, the size is set against the daily turnover of the specific name rather than the screen. Highly liquid SMI constituents absorb large lines cleanly; thinner mid- and small-caps are placed more selectively. Black Haven can take the line onto its own book to give a clean, priced exit.
03How do you execute a Switzerland block trade?
We work the line off the order book, off-market or at a negotiated price, and the block is then printed to SIX Swiss Exchange (SIX) under its block-trade rules. Black Haven Investments can take all or part of the risk on the line, so the seller achieves a clean exit at an agreed price.
04How large a block can you handle in Switzerland?
It depends on the stock’s free float, daily traded volume and volatility. We assess each line on its merits and indicate a workable size and price range after reviewing the position.
05Does the block trade have to be disclosed?
Often, yes. A substantial transfer by a significant shareholder is generally disclosable under the relevant regime overseen by FINMA. We manage the sequencing and wording of any required notification around the trade.
06Can you finance the buyer of the block?
Yes. A block can be paired with a stock loan to the acquirer, so the newly acquired Switzerland-listed line serves immediately as collateral for the financing that funds it.
07What is the settlement cycle for a Switzerland block trade?
The negotiated block is printed to SIX Swiss Exchange (SIX) under its block-trade rules and then settles on the standard T+2 cycle. We coordinate the print, the settlement and any financing legs so the line moves cleanly.
08At what level must a block be disclosed in Switzerland?
The principal threshold is 3%, under FMIA Art. 120 overseen by FINMA. A crossing by a substantial holder is notifiable; we sequence the print and the notice.
09Can you execute a block for a foreign or offshore seller?
Yes. The line is held with a qualified custodian and the block printed to SIX Swiss Exchange (SIX); we manage cross-border custody, settlement and the disclosure that attaches to a substantial transfer.
10How quickly can a Switzerland block be executed?
It depends on the stock’s liquidity and the size of the line relative to daily volume. Once mandated, many blocks are worked and printed within days; thinner lines are paced to limit market impact.
