The legal calculation can allocate the duty between parties and includes exemptions, but for an investor the practical point is simple: high turnover makes a small percentage recurring.
If this decision changes the viability or sequence of your move, a Swiss relocation strategy consultation can apply it to your own facts.
Why active investors notice it
A CHF 1 million foreign-securities purchase can represent CHF 1,500 of gross duty at 0.15% before considering statutory allocation and exemptions. If the portfolio is turned over repeatedly, stamp duty can become more important than brokerage commission.

Foreign broker
Where no Swiss securities dealer is involved, the Swiss transfer stamp-duty mechanism may not apply. That is one reason some Swiss residents keep foreign brokerage custody.
The trade-off is more personal tax reporting and foreign legal/custody exposure.
Whether a foreign broker will open the account in the first place is the prior question. FreedomBanking compares international brokers by the residence they accept.
Do not confuse it with issue stamp duty
Swiss corporate equity can also face a separate 1% issue stamp duty on qualifying equity contributions above the statutory CHF 1 million exemption threshold.

For buy-and-hold investors, stamp duty is usually manageable. For high turnover, model it explicitly.
The investor-life examples
The German research illustrates why turnover matters. A CHF 500,000 allocation to foreign ETFs, held for ten years and then sold, produces a very different lifetime cost from rebalancing the full portfolio every year. At 0.15%, repeated turnover can turn a line item that looked negligible into five figures over a decade.
This is one reason to separate investment strategy from broker location. A buy-and-hold investor may happily accept the Swiss infrastructure and tax reporting. A high-turnover trader may put much more weight on a foreign intermediary where the Swiss securities-dealer condition is not met.
Three boundaries to keep clear
First, statutory exemptions exist for specific transactions and counterparties. Second, transfer stamp duty is not the same as the 1% issue stamp duty that can apply to corporate equity contributions above the exemption threshold. Third, Swiss tax residence does not by itself create transfer stamp duty on every trade: the involvement of a Swiss securities dealer is central.
Do not rebuild an entire custody arrangement solely around this tax. Model it together with FX, custody, commissions, reporting and legal jurisdiction.
