Until there is any change in the number of constituents or any corporate actions affecting the prices, the existing divisor value will hold. 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. Investors may own a handful of stocks within their investment portfolio in which the 5 major stock investing strategies for value investors they track each stock’s individual performance.
Is the S&P 500 Better Than the Dow Jones Industrial Average?
While each has its own benefits, the S&P provides a better indication of how the stock market (and economy) is performing as it is made up of 500 of the largest stocks in the U.S. The Dow Jones, on the other hand, is made up of 30 of the largest companies in the country. Suppose that stock B takes a corporate action that changes the stock’s price without changing the company valuation. Say it is trading at $90, and the company undertakes a 3-for-1 stock split, tripling the number of available shares and reducing the price by a factor of three, i.e., from $90 to $30. 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).
Why Is the Dow Jones Industrial Average (DJIA) Price Weighted?
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 Dow tracks the stock performance of 30 blue-chip, American companies. The index is price-weighted and dates back to 1896, making it one of the oldest stock market indexes. It’s not as diversified as broader indexes like the S&P 500, but it still provides a picture of how the stock market and large businesses are performing. 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.
What Is the Dow Jones Industrial Average?
This means the positive price movement in one stock has canceled the equal value but the negative price movement of another stock. 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.
However, the performance of a small portfolio is not indicative of the overall market. Investors also need information about market sentiment, which is where a stock index can be helpful. 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 DJIA initially launched with just 12 companies based mostly in the industrial sectors.
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. The Dow is a price-weighted index, which means the stocks are weighted in the index based on their share price. This can create some unique situations, such as a company with a smaller market cap than other companies in the index having a larger weight because its share price is higher. Stock splits have a particularly large impact on price-weighted indexes for this reason. 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.
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. However, you cannot invest directly in the Dow Jones Industrial Average because it is just an index.
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.
Assume that stock A is trading at $20 per share and stock B is trading at $80 per share on day 1. The Dow Jones Industrial Average, or the Dow for short, is one way of measuring the stock market’s overall direction. When the Dow goes up, it is considered bullish, and most stocks usually do well. When the Dow falls, it is bearish, and most stocks typically lose money. 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.
But in the Dow, it has just the 15th largest weight, which is based on its share price of about $183. UnitedHealth Group has the largest weight in the Dow because of its $522 share price despite having a market cap that is less than 25 percent of Apple’s. The Dow Jones Industrial Average, also known as the Dow, is one of the most popular stock market indexes, along with the S&P 500 and Nasdaq Composite.
- Dow Jones was not a single person, but two of the three people who founded Dow Jones & Company in 1882.
- 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 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.

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. 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.
