In this guide
What it means
The SMI is concentrated in large, liquid companies. The SPI is broader and reflects more of the Swiss listed equity universe.
How to use it
Investors use the SMI for blue-chip tracking, quick market reads and large-cap exposure. They use the SPI to understand the wider market and reduce single-index concentration.
Investor checklist
Check index composition, sector weights, fund availability, fees, replication method and whether dividends are included in the return view you are comparing.
