What Is the Dow Jones Industrial Average DJIA?

This movement gives investors and traders a way to track the market based on the changing prices of those 30 stocks. The DJIA appears widely on financial and other news websites every day. This means that the Dow gives more weighting to companies with more expensive stock. The DJIA’s price weighting does not account for market capitalization, which is the total market value of all of a company’s shares.

  1. Over the last 10 years, the Nasdaq 100 averaged 18.34% annual returns while the DJIA averaged 11.11%.
  2. The DJIA’s methodology of calculating an index is known as the price-weighted method.
  3. At its inception, the Dow Jones Industrial Average comprised just 12 companies based in mostly industrial sectors such as railroads, oil, cotton, gas and sugar.
  4. Still, despite this and its relatively small number of component stocks, the Dow Jones Industrial Average is one of the most-respected market indexes in the world.

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. Beyond this, a stock is typically added only if the company “has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors”, according to S&P Global.

The Downside of the Dow

At the Dow’s inception, Charles Dow calculated the average by adding the prices of the 12 Dow component stocks and dividing by 12. Over time, there were additions and subtractions to the index that had to be accounted for, such as mergers and stock splits. The DJIA’s methodology of calculating an index is known as the price-weighted method. On top of having to deal with stock splits, the downside to this method is that it does not reflect the fact that a $1 change for a $10 stock is much more significant (percentage-wise) than a $1 change for a $100 stock. Another major criticism involves the fact the DJIA is a price-weighted index, meaning the average is based just on the price of component company stocks. Other major indices, such as the S&P 500, are market-capitalization-weighted, a system that values a company by taking the current stock price and multiplying it by the number of outstanding shares.

Dow was known for being able to explain complicated financial news to the public. He was also a firm believer in using the price movements of different stocks to predict market movements. He ended up creating a number of the benchmark market averages—still in use today—to indicate whether the stock market is rising or falling. Traders and fund managers use major stock indices to get an overview of how markets are performing. 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.

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. Stocks with higher share prices are given greater weight in the index. So a higher percentage move in a higher-priced component will have a greater impact on the final calculated value.

However, Forbes Advisor Australia cannot guarantee the accuracy, completeness or timeliness of this website. The Dow Divisor is manually adjusted by The Wall Street Journal (owned by Dow Jones) to account for share buybacks, splits, payment of dividends, and other changes to Dow index companies’ stocks. In the course of its lengthy history, its holdings have changed just 60 times, or about an average of every two years. Companies are replaced when they no longer meet the index’s listing criteria with those that do.

Keep in mind that the Nasdaq 100’s strong returns are in large part due to its large weighting in tech stocks. The Russell 2000 index is considered a benchmark for smaller U.S. stocks. Data are provided ‘as is’ for informational purposes only and are not intended for trading purposes.

To calculate the first average, Dow added up the stock prices and divided by 11—the number of stocks included in the index. The value of the index can also be calculated as the sum of the stock prices of the companies included in the index, divided by a factor, which is approximately 0.152 as of November 2021[update]. The factor is changed whenever a constituent company undergoes a stock split so that the value of the index is unaffected by the stock split.

They provide a basic signal of how specific markets perform during the day. Where p are the prices of the component stocks and d is the Dow Divisor. In the world of finance, you’ll often hear people ask, “How did New York do today?” or “How did the market perform today?” In both cases, these people are likely referring to the DJIA, as it is the most widely-used index. It is more popular than both the S&P 500 Index, which tracks 500 stocks, and the Nasdaq Composite Index, which includes more than 2,500 U.S. and international equities. The Dow Jones index is made up of 30 large, blue chip companies listed on the NYSE or the Nasdaq. The index is named after its creator Charles Dow and his business partner, statistician Edward Jones.

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. To compensate for the effects of the split, we have to adjust the divisor downward to 9.5.

Index Components

Most stock market indexes are weighted by market capitalization — equal to share price times the number of shares outstanding — but the Dow Jones Industrial Average is price-weighted. The value of the Dow Jones Industrial Average is calculated by determining the average value of the stock prices of the 30 listed companies. However, calculating that average value is not as simple as totaling the 30 stock prices and dividing by 30.

What Is the Meaning of Dow in the Stock Market?

This change in price brings down the average even though there is no fundamental change in the stock. To absorb the effects of price changes from splits, those calculating the DJIA developed the Dow divisor, a number adjusted to account for events like splits and used as the divisor in the calculation of the average. The Dow Jones Industrial Average (DJI), also known as the Dow Jones, the Dow 30, or DJIA, is a price-weighted measure of 30 U.S. “blue chip” company stocks trading on the New York Stock Exchange and NASDAQ. The Dow Jones index was created in 1896 by Charles Dow and Edward Jones. As of June 2021,[update] Goldman Sachs and UnitedHealth Group are among the highest-priced stocks in the average and therefore have the greatest influence on it.

Because it tracks the performance of 500 of the largest public companies, the S&P 500 Index is much broader in scope than the DJIA. Unlike the DJIA, the S&P 500 is market capitalization-weighted, not price-weighted. Because it’s more diversified and considers companies based on market cap, it may be a better indicator of the overall stock market’s performance. 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.

When they do it’s because a company’s importance or influence in its industry has fallen. The result of the calculation is the Dow Jones Industrial Average (DJIA) “close” for that day. For example, on Dec. 11, 2020, the Dow closed at 30,046.37, up 47.11 ($47.11) from the previous day, or +0.16%.

The Nasdaq index tracks more than 2,500 stocks, or almost every stock traded on the Nasdaq Exchange. For novice investors who want portfolio exposure to a wide range of sectors through familiar large-cap stocks, the companies of the Dow Jones Industrial Average represent a good starting point for your research. That’s especially true if you’re seeking to invest in blue chip companies, which are generally the most stable and profitable on the market.
