Please note that many of the most important companies, among them the largest employers and some market leaders are either more or less state owned (like the federal Post, all major railway companies as well as cantonal insurance companies for buildings), organized in the form of mutual benefit associations (like supermarket chains #1 Migros and #2 Coop, insurance company Mobiliar, allmost all health insurance companies and Raiffeisenbank), while others are exclusively controlled by families. Supermarket chain #3 DENNER used to be family controlled, but was taken over by #1, Migros when German discounters ALDI and Lidl announced their entry into the Swiss market a few years ago. Some state owned companies like Swisscom and some cantonal banks have been partly privatized in the 1990's.
Besides, thousands of small and midsize companies play an important role, not only from a financial point of view, but also regarding technical innovation. So the stock market alone does not give a complete picture of Switzerland's economy.
