The most often quoted stock market indicator is the Dow Jones Industrial Average (DJIA). In 1884, Charles Dow averaged closing prices of 12 representative stocks and the DJIA was christened. Since then it has been expanded to include 30 familiar blue chip companies to be more representative of the country's largest companies.

The calculation is also changed to reflect stock splits. While this index is not reflective of the entire stock market, watching changes in the DJIA can help you stay abreast of current conditions.
