Stock Indexes Worldwide – What is a Stock Index?

A stock index is a statistical measure that tracks the performance of a group of stocks. These stocks are selected to represent either a specific segment of the market, such as technology companies or small-cap firms, or the market as a whole.

Indexes are calculated using various methods, including price-weighted, market-cap-weighted, and equal-weighted formulas. For example:

A price-weighted index gives more influence to higher-priced stocks (like the Dow Jones Industrial Average).
A market-cap-weighted index gives more influence to larger companies based on their market capitalization (such as the S&P 500).
An equal-weighted index treats all stocks in the index equally, regardless of their size or price.
