Blue-chip index of the 20 largest and most liquid stocks on the SIX Swiss Exchange, launched in 1988 and subject to a weighting cap per constituent. A small number of large pharmaceutical and consumer companies dominate it.

No live level is shown for this asset: our open, keyless sources cover crypto, major FX crosses, the ECB policy rate, the US 10-year yield and US CPI — index levels and commodity prices are only available from licensed vendors, and we do not publish figures we cannot source openly.
