About the SPI
The Swiss Performance Index (SPI) is considered Switzerland's overall equity market index. It comprises practically all of the SIX Swiss Exchange-traded equity securities of companies that are domiciled in Switzerland or the Principality of Liechtenstein. Upon request, foreign companies with a primary listing on SIX Swiss Exchange may also be included in the SPI. The SPI does not include equity securities with a free float of less than 20% or shares of investment companies. These are included in the Swiss All Share Index.
The SPI is free-float-adjusted, which means that the market capitalization is adjusted according to the number of shares in fixed ownership. Only the tradable portion of the shares is taken into account in the index. The SPI is divided into sectors according to economic activity and according to size, i.e. small, medium-sized and large.
The SPI is continuously reviewed. As soon as an instrument fulfills the selection criteria, it is included in the index. As soon as a component no longer meets the selection criteria, it is removed from the index. The SPI was published for the first time on 1 August 1987 and has been calculated since June 1, 1987, when it was standardized at 1,000 points. The index is recalculated and published every three minutes.
