The SMI Expanded comprises the SMI and the SMIM and hence the 50 most highly capitalised securities
in the Swiss equity market. It represents about 95% of the capitalisation
of the freely tradable shares of the Swiss equity market and is calculated both as a performance
index and as a price index.
The SMI Expanded was standardised at 1'000 points on 31 December 1999 for the
performance index and at 100 points for the price index. It was introduced on 15 November 2004.
In order to facilitate trading and comparability, on 2 August 2005 the price index was
retroactively standardised at 1'000 points as of 31 December 1999.
