The Dow Jones Industrial Average (DJIA) is another well-known stock index that tracks the performance of 30 large-cap U.S. companies across various sectors. It is often referred to as the "blue-chip index" because it consists of well-established, dividend-paying companies. The DJIA is considered a benchmark for the U.S. stock market and is often used to gauge the market's performance.

NASDAQ Composite: The Tech Giant

The NASDAQ Composite is a broad-based index that tracks the performance of all companies listed on the NASDAQ stock exchange.

Case Study: Apple Inc. (AAPL)

To illustrate the significance of these indexes, let's take a look at Apple Inc. (AAPL), one of the largest companies in the world. Apple is a component of all three major indexes: the S&P 500, the DJIA, and the NASDAQ Composite. As a result, the performance of Apple significantly impacts these indexes.

When Apple reported strong earnings or launched a new product, the S&P 500, DJIA, and NASDAQ Composite often saw positive movements.

This highlights the influence that major companies have on the broader market.
