What is the SMI?
The Swiss Market Index (SMI) is the flagship index of the Swiss Stock Exchange, launched on June 30, 1988 with a base of 1,500 points. Managed by SIX Swiss Exchange, it tracks the 20 largest and most liquid Swiss stocks, with its composition reviewed once a year, in September.
How can you invest in the SMI?
The most common route is an ETF tracking the index, widely available on international platforms, or futures and options traded on Eurex. There is also an equal-weighted version, the SMI Equal Weighted Index, which reduces the influence of the three largest constituents.
What sectors dominate the SMI?
Healthcare (Novartis, Roche), food (Nestlé) and luxury goods (Richemont) account for most of the index's weight, giving it a defensive profile that stands out during periods of global market stress. The index reached an all-time high near 14,142 points in late June 2026, driven by these non-cyclical heavyweights.
What are the risks and limitations of the SMI?
With only 20 constituents and three companies (Nestlé, Novartis, Roche) traditionally accounting for nearly half the index, the SMI is heavily concentrated despite its image as a diversified, defensive market. The index is also structurally exposed to the Swiss franc: a sharp rise in the currency hurts the exporting companies that make up most of the index, a risk that materialized dramatically in 2015.
How has the SMI performed during past crises?
2008 was severe, with an annual decline of about 35%. But the most singular episode remains the "franc shock" of January 15, 2015: by unexpectedly abandoning its cap against the euro, the Swiss National Bank triggered a roughly 30% surge in the franc within minutes and sent the SMI down 8.7% in a single session (as much as -14% intraday), its worst one-day drop in 26 years — a monetary-policy risk unique to Switzerland, with no direct equivalent on other European indices.
