It consists of 30 large, publicly-traded companies from various industries, including technology, finance, and consumer goods. The DJIA is often used as a benchmark for the overall health of the US stock market. It's important to note that the DJIA is price-weighted, meaning that the influence of each component is proportional to its share price.

The S&P 500 is widely considered a proxy for the US stock market as a whole. This index is market capitalization-weighted, meaning that the influence of each company is proportional to its market value.
