The average is computed by adding up the closing prices of the common stocks of these companies and dividing by a divisor (currently 1.314). For example, if all the stock prices added up to 1,498.2885, the closing Dow would be 1,140.25. By changing the divisor occasionally (the last change was Sept. 1, 1981), the average can be compared with previous years, regardless of stock splits or substitutions of companies on the list.
