This article is about index in an economics and finance sense. For other uses, see Index.

In economics and finance, an index (for example a price index or stock market index) is a benchmark of activity, performance or any evolution in general.

Consumer price indexes (an inflation measurement) or a country GDP index (an economic growth measurement) can be used, among other things to adjust salaries, bonds interest rates, tax thresholds.

Some investment funds (index funds) manage their portfolio so that their evolution always mirrors (tracking) the evolution of a stock market index.
