It is easy to confuse Dow Jones with the Dow Jones Industrial Average (DJIA). Often referred to as “the Dow,” the DJIA is one of the most-watched stock indexes in the world, containing companies such as Apple, Boeing, Microsoft, and Coca-Cola. https://forexhero.info/ Dow Jones was not a single person, but two of the three people who founded Dow Jones & Company in 1882. Charles Dow was the Dow in Dow Jones, Edward Jones was the Jones, and Charles Bergstresser was the company’s third founder.
- Another major index is the Dow Jones Utility Average, which tracks 15 U.S. utility stocks.
- Dow Jones, or more precisely, Dow Jones & Company, is one of the world’s largest business and financial news companies.
- Although investors can’t invest directly in the index, they can park their money in a mutual fund or ETF that tracks the performance of the Dow Jones.
- Some of the Dow’s power and influence is due to its sheer venerability as the second-oldest stock market index.
An index can provide a measurable and traceable number that represents the overall market, a selected group of stocks, or a sector. For example, let’s say your individual portfolio of stocks (or your mutual fund) returned 15%, but the market index returned 20% during the same period. As a result, your portfolio’s performance (or your fund manager’s performance) would be lagging behind the market.
Assume that stock A is trading at $20 per share and stock B is trading at $80 per share on day 1. 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. Still, many institutional investors and index investors prefer to mimic market-cap weighted indexes like the S&P 500 rather than the Dow.

The Dow is not calculated using a weighted arithmetic average and does not represent its component companies’ market cap unlike the S&P 500. Rather, it reflects the sum of the price of one share of stock for all the components, divided by the divisor. Thus, a one-point move in any of the component stocks will move the index by an identical number of points.
These changes often come in batches and always keep the total membership at 30 companies. Dow Jones & Company is the firm founded by Charles Dow, Edward Jones, and Charles Bergstresser in 1882, not the people themselves. Charles Dow and Edward Jones ran the company themselves in the early years and built a reputation for integrity.

Over time, companies from other sectors were added and the number of stocks expanded to 30, turning the index into a vital indicator of the US economy’s momentum. Historically, DJIA’s performance has tracked very close to the overall stock market’s. So in the eyes of analysts and investors alike, as the Dow goes, so goes the nation — even the world — of stocks. The DJIA tracks the price movements of 30 large companies in the United States. The selected companies are from all major U.S. sectors, except utilities and transportation.
The Dow Jones Industrial Average groups together the prices of 30 of the most traded stocks on the New York Stock Exchange (NYSE) and the Nasdaq. It is an index that helps investors determine the overall direction of stock prices. Dow Jones & Company owned the DJIA as well as many other indexes that represent different sectors of the economy. They included the oldest index, the Dow Jones Transportation Average, which tracks 20 transportation companies, such as airlines and delivery services. Another major index is the Dow Jones Utility Average, which tracks 15 U.S. utility stocks. Let’s assume that the exchange constructs a mathematical number represented by AB Index, which is being measured on the performance of the two stocks (A and B).
Investing in the DJIA is possible via index funds as well as via derivatives such as option contracts and futures contracts. The table below alphabetically lists the companies included in the DJIA as of June 2022. Although the Dow Jones Industrial Average rarely changes, there are occasional additions and deletions.
A stock index allows investors to gauge the movement in the value of the market, while also providing an average measure of the individual company stock prices that make up the index. So a higher percentage move in a higher-priced component will have a greater impact on the final calculated value. At the Dow’s inception, Charles Dow calculated the average by adding the prices of the 12 Dow component stocks and dividing by 12.

The Dow Jones Industrial Average (DJIA), also called the Dow Jones Index or just The Dow, is a stock market index tracking 30 large ‘blue-chip’ companies listed on the New York Stock Exchange and the Nasdaq. Globally, investors track a number of major indices but the ones most followed across the world include the US-based Dow Jones Industrial Average, the Standard & Poor’s 500 and the Nasdaq Composite index. It may not have as many stocks as some other indexes, but what it has is choice — a representative cross-section of corporate America’s major players. And, as noted above, the roster does periodically change, representing the rise or fall of different sectors. Some of the Dow’s power and influence is due to its sheer venerability as the second-oldest stock market index. The fact that it represents and reflects the market movements of companies such as Microsoft, Boeing, IBM, and Coca-Cola is another reason for its significance.
This movement gives investors and traders a way to track the market based on the changing prices of those 30 stocks. The Dow is also a price-weighted index, as opposed to being weighted by market capitalization. This means that stocks in the index with higher share prices have greater influence, regardless if they are smaller companies overall in terms of market value. This also means that stock splits can have an impact on the index, whereas they would not for a market cap-weighted index. Traders and fund managers use major stock indices to get an overview of how markets are performing.
How many companies are on the Dow Jones?
That is, assuming the stock prices from the old index are held constant, the addition of a new stock price should not affect the index. This is a sudden dip in index value open source internet of things from the previous 57.5 to 41.67, just because a new constituent is getting added to it. Assuming that stocks A and B maintain their earlier day prices of $30 and $85.
Meanwhile, Apple (AAPL), with its $3 trillion market capitalization, is seven times the market cap of UnitedHealth, but its weighting in the Dow is less than half of UNH. But in the S&P 500, AAPL’s weighting is 7.5% vs 1.1% for UNH and 0.4% for INTC given it is a market-cap weighted index. For example, the current share price for healthcare stock UnitedHealth Group (UNH) is around $480, while semiconductor stock Intel (INTC) trades closer to $33. This means that UNH has an outsized weighting (8.6%) in the Dow vs INTC (0.6%), and its price movements have a greater sway on the Dow index performance.
Because of this, companies with fewer expensive shares have a larger impact on the Dow’s value than companies with many cheaper shares. An index tries to model a particular industry or market—or even entire national economies. There are indexes for a vast array of securities, industries, market sectors and segments, geographic markets, investment themes and so on.
