SMI Index: High dependence on a few large corporations
The Swiss benchmark index, the SMI, is currently in the focus of financial experts. The reason for this is a strong concentration: the three largest companies – Nestlé, Roche, and Novartis – together account for 47.4 percent of the entire index. This high weighting means that the economic performance of the SMI is very strongly dependent on these few firms.
This so-called cluster risk became particularly evident through the recent share price losses at Novartis. When such a large corporation loses value on the stock market, it has a direct impact on the entire Swiss equity market. Investors must therefore closely monitor how these heavyweights perform, as their results significantly influence the index.
Despite these risks, the SMI has shown surprising stability in recent months. Experts note that the index is performing well overall despite fluctuations in individual stocks. This is partly because the Swiss economy is broadly based and the other companies in the index are able to partially offset the losses.
For private investors in Switzerland, the situation remains an important issue. Anyone investing in the SMI should be aware that diversification – the spreading of capital – is limited by the dominance of the three giants. A precise analysis of individual stocks therefore remains essential for a successful investment strategy.
