The '''SPI Extra''' is a stock index which tracks [mid-cap](/source/mid-cap) and [small-cap](/source/Small_cap_company) companies primarily listed in [Switzerland](/source/Switzerland). <ref name="moneyland">{{cite web|url=https://www.moneyland.ch/en/spi-extra-index-definition|title=SPI Extra Index Explained|publisher=Moneyland|accessdate=26 July 2019}}</ref> The index is calculated by [SIX Swiss Exchange](/source/SIX_Swiss_Exchange). <ref name="factsheet"/>

It includes all the shares from the [Swiss Performance Index](/source/Swiss_Performance_Index) (SPI) that are not included in the [Swiss Market Index](/source/Swiss_Market_Index) (SMI). <ref name="factsheet"/><ref name="NZZ">{{cite web|url=https://www.nzz.ch/finanzen/aktien/smim-und-spi-extra-besser-als-smi-mehr-rendite-auf-dem-nebenschauplatz-ld.109755|title=Mehr Rendite auf dem Nebenschauplatz|publisher=[NZZ](/source/Neue_Z%C3%BCrcher_Zeitung)|accessdate=26 July 2019}}</ref><ref name="fuw">{{cite web|url=https://www.fuw.ch/article/spi-minus-smi-gleich-spi/|title=SPI minus SMI gleich SPI Extra|publisher=Finanz und Wirtschaft|accessdate=26 July 2019}}</ref> It is therefore often used in investment portfolios such as [exchange-traded fund](/source/exchange-traded_fund)s (ETFs), as a small-cap and mid-cap benchmark that complements the SMI.

The SPI Extra was introduced on 29 April 2004, computed back to 3 January 1996 with a baseline value of 1000 points as of 31 December 1999. <ref name="factsheet"/>

==Constituents==

The index contains all the companies that are in the [Swiss Performance Index](/source/Swiss_Performance_Index) (SPI), but not among the 20 blue chips that are in the [Swiss Market Index](/source/Swiss_Market_Index) (SMI), or equivalently the [SPI 20](/source/SPI_20). <ref name="rules">{{cite web|url=https://www.six-group.com/exchanges/downloads/indexinfo/online/share_indices/smi/methodology_equity_and_re_en.pdf|title=SMI Indices|publisher=SIX Swiss Exchange|accessdate=18 April 2019}}</ref>

While the SPI Extra overlaps with the SPI Mid+Small, it does not fully coincide because the SMI criteria are not only based on market capitalisation, but also on liquidity.

==Tickers==

The following are the tickers for the SPI Extra total return, which takes dividends into account. There is also a version of the SPI Extra as a price index. <ref name="factsheet"/>
