Why Is the Dow Jones Price Weighted?
The Dow Jones Industrial Average (DJIA) is an example of a price-weighted index. When it was created in 1896 by Charles Dow, it was meant to reflect the average price of stocks in the marketplace. To better understand how the Dow changes value, let’s start at its beginnings. When Dow Jones & Co. first introduced the index in the 1890s, it was a simple average of the prices of all constituents. With just 30 stocks, the Dow focuses on a relatively small number of large-cap, highly liquid names. With 500 stocks, the S&P 500 gives a much broader look at the market, still with a focus on large-cap companies.
The Nasdaq Composite contains all the stocks traded on the tech-heavy Nasdaq, including small-cap, midcap and large-cap names. The Nasdaq 100 features only the 100 largest nonfinancial companies trading on that exchange.

However, companies over the years have been removed or added while others have issued stock splits and spin-offs. These changes have impacted the prices of the stocks and the makeup of the index. As a result, it would be impossible to perform a historical comparison of the Dow’s current value versus in years past since so many of the components and prices have changed. Charles Dow likely chose to create a price-weighted index due to its simplicity. Previously, bonds were the typical investment, and their price stability and interest payments were easy for investors to grasp.
Until there is any change in the number of constituents or any corporate actions affecting the prices, the existing divisor value will hold.
