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. Over time, there were additions and subtractions to the index that had to be accounted for, such as mergers and stock splits.

A brief history of the Dow Jones Industrial Average

This is a sudden dip in index value 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. This would not be a very useful reflection of the overall health of the market. Plus, get timely analysis of the DJIA and 30 Dow stocks, including Apple (AAPL), Boeing (BA), Microsoft (MSFT), Walmart (WMT) and the newest addition, Walgreens Boots Alliance (WBA). The shares included in it are weighted according to price; the index level represents the average of the shares included in it. Stocks must meet certain requirements to be included, such as maintaining a minimum daily trading volume of 100,000 shares and having been traded on the Nasdaq for at least two years.

What are stock market indexes?

Many critics believe the S&P 500 is a better representation of the economy as it includes significantly more companies, 500 versus 30. 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. The Dow Jones index has been around since 1896, despite all of its known challenges and mathematical dependencies, the DJIA remains the most followed and recognized index globally. Investors and traders looking at using DJIA as the benchmark should consider the mathematical dependencies.

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. In 1889, they went on to found The Wall Street Journal, which remains one of the world’s most influential financial publications.

What Is the Dow Jones Industrial Average?

The Nasdaq 100 Index aggregates 100 of the largest and most actively traded non-financial domestic and international stocks traded on the Nasdaq Stock Market. The Dow Jones Industrial Average, also known as the DJIA or simply the Dow, is a market index frequently used to gauge the overall performance of the U.S. stock market. Trading is typically carried out in an open outcry fp markets review auction, or over an electronic network such as CME’s Globex platform. Companies in the DJIA are also chosen by a committee and are balanced to try to represent the state of the overall economy. This means that certain companies may be added to or deleted from the index periodically without much in the way of being able to predict when or which stock will be changed.

DJIA, S&P 500 And Nasdaq

Keep in mind that the Nasdaq 100’s strong returns are in large part due to its large weighting in tech stocks. On March 29, 1999, the average closed at 10,006.78, its first close above 10,000. This prompted a celebration on the trading floor, complete with party hats.[55] Total gains for the decade exceeded 315%; from 2,753.20 to 11,497.12, which equates to 12.3% annually. Many critics argue that the Dow does not significantly represent the state of the U.S. economy as it consists of only 30 large-cap U.S. companies. They believe the number of companies is too small and it neglects companies of different sizes.

According to S&P Global, the Dow Jones Industrial Average is a “world-renowned gauge of the U.S. equity market.” Most Dow Jones Industrial Average-listed companies trade on the New York Stock Exchange. Although the Dow Jones Industrial Average rarely changes, there are occasional additions and deletions. These changes often come in batches and always keep total membership at 30 companies.

Unemployment has now been below 4 percent for 27 months, a record last achieved in the late 1960s, ending in February 1970. Inflation is way down from its peak in 2022, although by most measures it’s still somewhat above the Federal Reserve’s target of 2 percent. U.S. economic growth over the past four years has been much faster than in comparable major wealthy nations.

Among the companies in the index are 3M, Chevron, Home Depot, IBM, Salesforce, and Visa. The DJIA is considered a bellwether of the stock market and the U.S. economy as a whole. 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. 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.

Investors use the Dow Jones industrial average, S&P 500 and Nasdaq composite to gauge strength or weakness in the U.S. stock market as a whole. Each of these three major indexes provides different insight into the current market trends. In the course of its lengthy history, its holdings have changed just 60 times, or about an average of every two years. In early 1981, the index broke above 1,000 several times, but then retreated. After closing above 2,000 in January 1987,[43] the largest one-day percentage drop occurred on Black Monday, October 19, 1987, when the average fell 22.61%.

Now assume that another company C lists on the stock exchange at the price of $10 per share on the fourth day. AB index wants to expand and increase the number of constituents from two to three, to include the newly listed C company stock in addition to the existing A and B 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). 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.

The ten components with the largest dividend yields are commonly referred to as the Dogs of the Dow. As with all stock prices, the prices of the constituent stocks and consequently the value of the index itself are affected by the performance of the respective companies as well as macroeconomic factors. 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 April 2024[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. This indicates that price-weighted indices (like Dow Jones and Nikkei 225) depend on the absolute values of prices rather than relative percentage changes.

The Nasdaq 100 features only the 100 largest nonfinancial companies trading on that exchange. Initially, the Dow Jones Industrial Average was an index of 12 companies. Over time, as the focus of the index shifted from measuring the performance of the heavy industrial sector to gauging the health of the entire U.S. stock market, the number of stocks in the index expanded. This difference in price weighting versus market-capitalization weighting can cause the DJIA to be more volatile than the S&P 500 in the short term. Price drops that are small percentages of share prices may have outsize impacts on the Dow in companies with smaller market caps but expensive shares. These stocks are from large companies with long histories of strong performance.

The DJIA is one of the oldest U.S. indexes, having been created in 1896. The Dow Jones Industrial Average hit 10,000 for the first time in March 1999. The DJIA then hit 11,750 in January 2000, before falling to below 7,200 in October 2002 after the dot-com crash. The table below alphabetically lists the companies included in the DJIA as of March 2024.

This has also been one of the criticizing factors of price-weighted indexes, as they don’t take into account the industry size or market capitalization value of the constituents. The DJIA is widely followed because it is considered one of the most reliable proxies for the broader market’s performance. It is also closely watched by investors, strategists, commentators and others because of its age and because of the prominence of its component stocks. 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. Because of this, companies with fewer expensive shares have a larger impact on the Dow’s value than companies with many cheaper shares.

Despite its limitations, however, the Dow still holds a special place in American finance. Individuals can invest in the Dow, which would mean gaining exposure to all of the companies listed in it, through exchange-traded funds (ETFs), such as the SPDR Dow Jones Industrial Average ETF (DIA). Companies are replaced when they no longer meet the index’s listing criteria with those that do. Over time, the index became a bellwether of the U.S. economy, reflecting economic changes.

As of 2024, Dow Jones & Company continued to be a major source of financial news. Its publications included MarketWatch, Barron’s, and, of course, The Wall Street Journal. What is more, these financial news outlets maintained considerable independence from News Corp. However, some critics argue that a price-weighted index, even with the divisor, is antiquated and lacks credibility. Nonetheless, the value of the Dow is widely used by market participants and the media as a gauge of the overall market’s performance. For instance, you may find a mutual fund or ETF that tries to mimic its performance.

These assets are normally comprised of the same companies that make up the index. Until there is any change in the number of constituents or any corporate actions affecting the prices, the existing divisor value will hold. An index can provide a measurable and traceable number that represents the overall market, a selected group of stocks, or a sector. A stock index can also serve as a benchmark for investment comparisons. 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.
