The Dow Jones and the S&P 500 are two of the most familiar market indexes. While they both serve as important market barometers, they differ in how they track the market.
The backbone of any index, including the Dow, is a consistent mathematical process known as weighting. Here’s how it works:.
The S&P 500
The Dow Jones Industrial Average (DJIA) and the S&P 500 are two of the most popular market indices. Each provides a unique view into how the stock market is performing and is often used as a benchmark against which investment portfolios are compared. But while these indices share many similarities, they differ in how their values are calculated and the types of companies that they include.
Both the DJIA and the S&P 500 track a sample of America’s largest publicly-traded companies. But they go about it in very different ways, and those differences can have an impact on how the indices perform. For example, the S&P 500 is “market-capitalization-weighted,” which means that the larger companies are given a greater weight in the index than smaller ones. The DJIA, on the other hand, is “price-weighted,” which means that it adds up the share prices of 30 companies and then divides by a predetermined constant, known as the Dow Divisor.
The result is that the value of a stock in the DJIA is impacted by its price per share, regardless of its actual market valuation. For instance, Goldman Sachs has a bigger influence on the DJIA than Walmart because it trades for nearly $200 per share while Walmart’s shares are currently trading at about $352.
In addition to its unique calculation method, the DJIA also includes fewer companies than either the S&P 500 or the Nasdaq. The Dow only includes 30 large, blue-chip firms that are household names. By contrast, the S&P 500 includes more than 3,000 companies and is more diversified in terms of its sectors.
In addition to being more diverse than the Dow, the S&P 500 is a better reflection of the overall economy than the DJIA. The DJIA is heavily weighted toward cyclical industries, such as heavy industry and financial services, while the S&P is more balanced across all sectors. In fact, the S&P’s tech sector is nearly twice as big as its cyclical counterpart. As a result, the S&P tends to move more in tandem with the economy than the Dow does.
The Dow Jones Industrial Average (DJIA) is one of the best-known market indices in the world, but it’s far from the only index that people track. The Nasdaq and S&P 500 are two other indices that most investors pay attention to. Each offers a different view of the market, and investors may use them to help inform their investing decisions.
The DJIA is price-weighted, meaning that changes in the share prices of all 30 of its components affect the index’s value equally. This approach was originally intended by Charles Dow to ensure that the index was as representative as possible of the entire market. However, in practice it leads to a situation where movements in the shares of high-priced companies tend to have a much greater impact on the index’s overall value than those in lower-priced stocks. To address this, a divisor was formally introduced later to make the index more reflective of market capitalization.
As a result, the value of the index may change more often than other market indices, because its values are highly volatile. However, the DJIA is generally considered to provide a good representation of the overall market, especially because it includes blue chips – established companies with well-known products and services that are viewed as relatively stable and reliable.
The Nasdaq, on the other hand, is a market-capitalization-weighted index that focuses on large-cap stocks. It contains more than 2,500 stocks, most of which are traded on the Nasdaq stock exchange. As a result, it is more heavily weighted toward technology stocks than the Dow and the S&P 500.
Investors cannot trade directly on the NASDAQ or the Dow, but they can purchase mutual funds and exchange-traded funds that track these indexes and thus replicate their performance. This allows them to benefit from the indices’ mathematical averages without having to purchase every single stock included in the indexes, which can be expensive and time-consuming.
Another important difference between the NASDAQ and the Dow is that the former is known as a high-tech exchange, while the latter has a more traditional focus on more established companies with steady revenue streams.
The Russell 2000
When it comes to the stock market, there are a few indices that most people are familiar with. The Dow Jones Industrial Average, or the Dow for short, is one of the most widely referenced indices in the world, and it tracks the performance of 30 significant public companies that trade on the New York Stock Exchange or the Nasdaq stock exchange. The Dow has been in existence since 1896, and it has a reputation for being a reliable indicator of overall market trends.
In contrast, the S&P 500 is a more diversified index that tracks the performance of 500 different stocks. This index is often used to determine how the broader stock market is faring, and it can be useful for identifying opportunities in specific sectors. This index is also often used to make long-term investments, as it has historically yielded decent returns over time.
One of the main differences between the Dow and the S&P is that the Dow is price-weighted, while the S&P is market-capitalization-weighted. This means that changes in the share prices of individual companies will have a different impact on the index’s value, and the movement of the higher-priced stocks will have a greater effect than the movement of the lower-priced stocks.
The Russell 2000 is an index that tracks the performance of small-cap stock companies in the United States. The companies in this index must have a market cap of between $300 million and $2 billion and meet certain other requirements to be included in the index. Because these companies are smaller than their larger counterparts, they are more likely to experience more volatility in their share prices. This makes them less predictable for investors, but it also means that they can grow much more quickly than their large-cap counterparts.
Investors can purchase shares in the individual companies that comprise the Russell 2000 index, and many brokers offer low commissions on trades and allow investors to buy fractional shares. Alternatively, investors can track the performance of the Russell 2000 through a mutual fund or exchange-traded fund (ETF). ETFs offer the convenience and diversification of an index without the hassle of buying and selling individual stocks.
The CBOE Volatility Index
The CBOE Volatility Index, commonly known as the VIX, is a market index that is often used to measure stock market volatility. Its value is based on a formula that incorporates options-based theory with current options-market data. Unlike other market indices, the VIX doesn’t include stocks from individual companies. It is a useful tool for investors to use in assessing the risk of investing in the market.
In general, a market index is a basket of stocks that is used to measure the performance of a particular market or sector. There are a wide range of market indices, from the most popular (Dow Jones, S&P 500) to less well-known ones (S&P Small Cap 600, Nasdaq 100). Most people are familiar with these indexes through index funds and exchange-traded funds that track them.
There are a few important differences between the Dow Jones and NASDAQ. The first difference is the number of companies included in each index. The NASDAQ includes about 3,000 companies, while the Dow Jones contains 30 major industry leaders. The second difference is the way the indices are calculated. The Dow Jones is a price-weighted index, while the NASDAQ is a market capitalization-based index.
The Dow Jones is one of the oldest market indices in the United States. It was developed by Charles Dow, a co-founder of The Wall Street Journal, to provide a snapshot of the economy. The Dow is made up of 30 large-cap stocks, often referred to as blue chips. The companies that make up the Dow are chosen by a committee, and they are replaced when they leave the index or when their stock prices fall too low to be representative of the overall economy.
The NASDAQ is different from the Dow Jones because it is a market index that tracks technology-based companies. The NASDAQ includes 3,000 companies, but it only tracks the top 100 companies by market value. The NASDAQ is a good gauge for technology stocks, and it can be used to determine the overall health of the tech sector. In addition, the NASDAQ can be used to predict how much stock price volatility is likely in the future.
The Dow Jones Industrial Average (DJIA) is one of the most well-known and widely followed stock market indices in the world, but it is not the only one. There are several other market indices that investors use to track the performance of various segments of the stock market. In this answer, we’ll compare the DJIA to a few other major indices.
- S&P 500: The S&P 500 is a market-capitalization-weighted index of 500 large-cap stocks listed on the New York Stock Exchange or NASDAQ. It is often considered a more comprehensive barometer of the U.S. stock market than the DJIA because it includes a larger number of companies from different sectors.
- NASDAQ Composite: The NASDAQ Composite is a market-capitalization-weighted index of all the common stocks and similar securities listed on the NASDAQ stock market. It is often used as a benchmark for technology and growth-oriented companies, as many of these firms are listed on NASDAQ.
- Russell 2000: The Russell 2000 is a market-capitalization-weighted index of 2,000 small-cap companies listed on U.S. exchanges. It is often used as a benchmark for the performance of small-cap stocks and is considered to be a good indicator of the overall health of the U.S. economy.
While the DJIA is a widely recognized index, it is important to note that it only includes 30 large-cap stocks, which may not be representative of the broader market. Additionally, the DJIA is a price-weighted index, meaning that the companies with the highest stock prices have the greatest influence on the index’s performance. This can result in distortions in the index’s movements.
Investors often use a combination of indices to track the performance of their portfolios and the overall market. Each index has its strengths and weaknesses, and it is important to understand the characteristics of each when making investment decisions.

Q: What is the S&P 500?
A: The S&P 500 is a market-capitalization-weighted index of 500 large-cap stocks listed on the New York Stock Exchange or NASDAQ.
Q: What is the NASDAQ Composite?
A: The NASDAQ Composite is a market-capitalization-weighted index of all the common stocks and similar securities listed on the NASDAQ stock market.
Q: What is the Russell 2000?
A: The Russell 2000 is a market-capitalization-weighted index of 2,000 small-cap companies listed on U.S. exchanges.
Q: Which is better: the DJIA or the S&P 500?
A: There is no definitive answer to this question, as both indices have their strengths and weaknesses. The DJIA is a price-weighted index that includes only 30 companies, while the S&P 500 is a market-capitalization-weighted index that includes 500 companies. Some investors prefer the S&P 500 because it is considered to be a more comprehensive indicator of the U.S. stock market, while others prefer the DJIA because it has a longer history and is more widely recognized. Ultimately, the choice between the two indices depends on an investor’s investment goals and risk tolerance.
