Short answer
SMI ETFs provide concentrated blue-chip exposure; SPI ETFs provide broader Swiss equity exposure.
In this guide
What it means
The SMI can be efficient and liquid, but concentrated. The SPI can better represent the Swiss market, but investors must check fund availability and liquidity.
How to use it
Use SMI funds for large-cap Swiss exposure and SPI funds when breadth matters more than pure blue-chip liquidity.
Investor checklist
Check TER, replication, distribution policy, fund currency, listing venue, spread, tax documents and portfolio overlap.
