Stock Market Index Meaning

A statistical tool that reflects changes in the financial markets is a stock market index. The indices serve as performance indicators for either a specific market segment or the entire market.

Selecting particular stocks from related companies or those that satisfy a set of specified criteria results in the creation of a stock market index. The exchange already lists and trades these shares. A number of selection criteria, like industry, market sector, or market capitalization, can be used to generate stock market indexes.

Each share market index tracks the performance of the shares that make up that index in terms of both price movement and share performance. Basically, this indicates that the performance of any stock market index is directly inversely correlated with the performance of the underlying stocks that comprise the index. In simple and plain language, as the prices of the stocks which is in index rise, same time index will go up.
