The '''SPI Extra''' is a stock index which tracks mid-cap and small-cap companies primarily listed in 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. <ref name="factsheet"/>
It includes all the shares from the Swiss Performance Index (SPI) that are not included in the 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|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 funds (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 (SPI), but not among the 20 blue chips that are in the Swiss Market Index (SMI), or equivalently the 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"/>
