The Swiss Performance Index (SPI) is considered Switzerland's overall stock 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, thereby enabling their future inclusion
in the SLI or SMI Family. 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. show more
The SPI is free-float-adjusted, which means that the market capitalisation 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 a performance index. Dividend payments are taken into account in calculating the
index. The SPI is also calculated as a price index (i.e. without adjustment for dividends).
The SPI has been calculated since 01.06.1987, when it was standardised at 1'000 points.
The index is recalculated and published every three minutes.
