The SPI 20 is a capitalization-weighted stock index of large-cap companies listed on the SIX Swiss Exchange.
It is made up of the same components as the Swiss Market Index, except that it does not have any cap on the maximum percentage that a component can have. It was created in 2017, after the largest SMI constituents were capped at 18%. The index was standardized at 1500 points on 30 June 1988 and the history is available back until 29 January 1988.
