Principally managed by the SIX Swiss Exchange, Swiss stock market indices are key components of the global financial system. As the nerve centre of the Swiss financial market, the SIX Swiss Exchange was created by the merger of the Zurich, Geneva and Basel stock exchanges in 1995. Swiss indices reflect the performance of listed Swiss companies and are essential for assessing the country's economic health. The SMI (Swiss Market Index) is the benchmark stock market index in Switzerland. Relatively small, it comprises 20 of Switzerland's largest and most liquid companies. The broader SPI (Swiss Performance Index) covers virtually all the stocks listed on the SIX Swiss Exchange, providing a more comprehensive picture of the Swiss stock market. Financial services, pharmaceuticals, luxury goods... Swiss indices cover a wide range of sectors, reflecting the diversity and robustness of the Swiss economy.<Supervised by FINMA, the Swiss stock market attracts investors from all over the world, interested in the quality and stability of Swiss companies, as well as the country's low level of involvement in international conflicts. The SIX Swiss Exchange offers a range of derivatives based on its indices (including futures and options), enabling investors to implement hedging, arbitrage or speculation strategies.
