About the SMI
For more than 30 years, clients from around the world have relied on the SMI as underlying for their index funds, mandates, ETFs, structured products, index derivatives and more. The blue-chip index SMI is the most important equity index in Switzerland and comprises the 20 largest and most liquid equities from the SPI. The SMI covers approximately 75% of the market capitalization of the Swiss equity market and is a strong indicator of Swiss economic success.
The index components are selected based on their free-float adjusted market capitalization and based on their turnover. A capping of the weights (quarterly to 18% in each case and ad-hoc if the limits are breached) ensures that no two components exceed a weighting of 20%. This makes the SMI fully compliant with the ESMA UCITS guidelines and it can be used as a benchmark index for the Swiss equity market in the European Union.
The composition of the SMI is reviewed once a year in September. Its calculation takes place in real-time tick-by-tick, i.e. each new transaction involving a stock included in the SMI causes the index to be recalculated.
The SMI was standardized at 1,500 points on June 30, 1988.
