Industry Classification Benchmark

The Industry Classification Benchmark (ICB) is an industry classification taxonomy launched by Dow Jones and FTSE in 2005 and now owned solely by FTSE International. It is used to segregate markets into sectors within the macroeconomy. The ICB uses a system of 10 industries, partitioned into 19 supersectors, which are further divided into 41 sectors, which then contain 114 subsectors.

The ICB is used globally (though not universally) to divide the market into increasingly specific categories, allowing investors to compare industry trends between well-defined subsectors. The ICB replaced the legacy FTSE and Dow Jones classification systems on 3 January 2006, and is used today by the NASDAQ, NYSE and several other markets around the globe. All ICB sectors are represented on the except Equity Investment Instruments (8980) and Nonequity Investment Instruments (8990).

Dow Jones divested itself of its 50% interest in the ICB in 2011 and announced it was creating its own version of it.

Note that the terms "industry" and "sector" are reversed from the Global Industry Classification Standard (GICS) taxonomy and the more common usage by professionals.
