First calculated at 1,500 points in 1988, the SMI quickly rose to become Switzerland's most important equity index. But what is a blue-chip index? What are indexes used for? And how long have they been around? These and many other questions as well as the origin, history and significance of SMI, Dow Jones, Nikkei & Co is explained at this exhibition.
