Stock market index. A stock index or stock market index is a measurement of the value of a section of the stock market. It is computed from the prices of selected stocks (typically a weighted average). It is a tool used by investors and financial managers to describe the market, and to compare the return on specific investments.
These are market averages designed to tell you how companies traded on the stock market are doing in general. The Dow Jones Industrial Average is simply the average value of 30 large, industrial stocks. Big companies like General Motors, Goodyear, IBM and Exxon are the kinds of companies that make up this index. See Dow Jones & Company for details on how the average is calculated.
