These indicators are mainly used by the stock exchanges of various nations and each of them can be integrated by firms with certain characteristics such as having a similar market capitalization or belonging to the same type of industry. In addition, there are some indices that only consider a handful of shares to determine their value or others that consider hundreds of shares.
