What Are Market Indices?

A market index is a statistical measure that tracks the performance of a specific segment of the financial market, such as stocks, bonds, commodities, or currencies. It’s essentially a basket of securities that represents a particular market or sector, providing a snapshot of its overall performance.

2. Dow Jones Industrial Average (DJIA):

A price-weighted index of 30 large-cap US companies, often considered a bellwether for the overall US stock market.

How Are Market Indices Calculated?

Market indices are typically calculated using one of the following methods:
