About the SMI

The blue-chip index SMI is the most important equity index in Switzerland and comprises the 20 largest stocks from the SPI. The SMI covers approximately 75% of the total capitalization of the Swiss equity market. It is free-float-adjusted, which means that only the tradable portion of the shares is considered in the index. 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.

Because the SMI represents the Swiss equity market, it is used as an underlying index for many financial products such as options, futures, structured products and exchange traded funds.

On 30 June 1988, the SMI was standardized at 1'500 points. Its composition is reviewed once a year. Calculation takes place in real time, i.e. each new transaction involving a stock included in the SMI causes the index to be recalculated.
