Understanding Stock Market Indices

Stock market indices are a measure of the overall performance of a group of stocks. They provide a snapshot of the market's health and direction. Commonly used indices include the S&P 500, the Dow Jones Industrial Average, and the NASDAQ Composite.

The S&P 500

The S&P 500 is one of the most widely followed indices. It represents the performance of 500 large companies listed on the stock exchanges in the United States. This index is often considered a benchmark for the U.S. stock market and is used to gauge the overall market's performance.

The Dow Jones Industrial Average

The Dow Jones Industrial Average (DJIA) is another well-known index. It tracks the performance of 30 large, publicly-owned companies in the United States. The DJIA is often used as a gauge of the U.S. economy and is known for its historical significance.

The NASDAQ Composite

The NASDAQ Composite is an index that tracks the performance of all stocks listed on the NASDAQ exchange. It includes a wide range of companies, from technology giants to biotech startups. The NASDAQ Composite is often seen as a bellwether for the technology sector.
