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. 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. Despite its limitations, however, the Dow still holds a special place in American finance.
The Dow’s approach is unlike other leading indexes used to track the overall performance of the stock market, like the S&P 500 or the Nasdaq Composite. These consider a company’s market capitalization when determining how much influence it will have in an index. As the economy changes over time, so does the composition of the index. A component of the Dow may be dropped when a company becomes less relevant to current trends of the economy, to be replaced by a new name that better reflects the shift. For instance, a company may be removed from the index when its market capitalization drops because of financial distress.
Understanding the Dow Jones Industrial Average (DJIA)
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. Where p are the prices of the component stocks and d is the Dow Divisor.
- 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.
- As a constantly changing benchmark number, it’s endlessly watched, analyzed, and bet upon.
- 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.
Dow chose several industrial-based stocks for the first index, and the first reported average was 40.94. 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. 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 https://www.dowjonesrisk.com/ 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.
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 Dow’s unusual price-weighting (versus market-cap-weighting) system has weathered criticism almost from the index’s inception in 1896.
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. The DJIA is a stock index that tracks the share prices of 30 of the largest U.S. companies.
What Does the Dow Jones Industrial Average Measure?
Many critics of the Dow argue that it 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. Many critics believe the S&P 500 is a better representation of the economy as it includes significantly more companies, 500 versus 30. 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. When Dow died in 1902, Clarence Barron and Jessie Waldron bought the company, and control eventually passed to the Bancroft family.
The Dow Jones Industrial Average (DJIA)
Even today, for many investors, a strong-performing Dow equals a strong economy while a weak-performing Dow indicates a slowing economy. 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.
The Dow Jones Industrial Average is one of the world’s most influential stock indexes. Here’s how it works
Yarilet Perez is an experienced multimedia journalist and fact-checker with a Master of Science in Journalism. She has worked in multiple cities covering breaking news, politics, education, and more. This ETF puts 99.8% of its assets in all 30 Dow stocks, with the same weighting. It has no required minimum investment and has an expense ratio of 0.16%.
These stocks are from large companies with long histories of strong performance. Because of the prominence of the companies in the Dow and the age of the index itself, experts and financial commentators often use its performance as a proxy for the overall U.S. stock market. 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 0.153 as of February 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.
Charles Dow created various market averages to more accurately define which way ” industrial stocks” or ” transportation stocks” were headed. 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. Dow was known for his ability to explain complicated financial news to the public. He believed that investors needed a simple benchmark to indicate whether the stock market was rising or declining.
For these reasons, the Nasdaq 100 may reveal less about the overall U.S. stock market and tell you more about the economic performance of the global tech industry. In the course of its lengthy history, its holdings have changed just 60 times, or about an average of every two years. The Dow Jones Industrial Average is a stock index of 30 U.S. blue-chip large-cap companies, which has become synonymous with the American stock market as a whole. The index, however, only has 30 companies, and the index itself is price-weighted, meaning that it does not always present an accurate reflection of the broader stock market.
