How the Dow Jones Is Calculated The Dow Jones Industrial Average is one of the best indicators for the stock market.

Why does it matter to you?

It’s an extremely broad indicator that can accurately predict market movements. Dow Jones defines the average as: “The Dow Jones Index is a price-weighted average of 30 leading companies. It is designed to reflect the market value of the shares of large-capitalization, multinational companies.” That does sound boring, so why does it matter? For two reasons: price-weighting and precision. Price-Weighting The idea behind price-weighting is that all shares that make up the average have the same value. Therefore, the more expensive shares have more influence on the price of the average. This makes the Dow Jones Industrial Average a great measure of stock market trends. For example, when companies report disappointing earnings, it can cause the DJIA to fall. The lower the DJIA, the worse the news is.

How does it work?

The index consists of 30 stocks, so it’s a common denominator. Once a stock is added to the index, it’s added to the index until a company is removed from the index. When a stock is added to the index, it is multiplied by the price of that stock until it’s removed. Thus, a share of Apple’s stock will be added to the index as $76.00. If that stock were to rise to $100.00, it would be taken out of the index, but would still have a $76.00 price. So what happens to Dow 30 when the companies are added? They have a multiplier factor that is then added to the original price. Thus, shares of Apple and ExxonMobil would be multiplied by their price. The same would happen with Microsoft and General Electric and many others.

Around the time the US government was gearing up to declare war on Germany in 1914, some major US companies started getting involved in the European war effort. During this time, financiers and industrialists thought it would be good to keep track of the market and share prices for US companies. The idea of creating a list of companies to track the market became known as the Dow Jones Industrial Average in the 1920s. It wasn’t long before investors wanted to buy shares in these companies. They could invest in what would be considered high-flying companies by investors at that time. So, the DJIA was created and became publicly traded in 1928. As with any new publicly traded company, the founders listed the companies by market capitalization.
