Understanding & Investing in Dow Jones Stocks: A UK Investor’s Guide

The Dow Jones index, also known as the Dow Jones Industrial Average, was founded in 1885 by Charles Dow and Edward Jones. At its inception, this index comprised only the 12 most financially robust companies of that era. However, as time progressed, the number of companies incorporated into the index grew, reaching 20 in 1916 before eventually stabilising at 30 in 1928. Since then, the Dow Jones index has evolved to become one of the oldest stock indices in history.

What is the Dow Jones index?

The Dow Jones Industrial Average index (DJIA) represents a carefully curated basket of 30 stocks, whose collective value fluctuates based on the performance of its individual components. When the majority of these stocks experience a decrease in value, the index is likely to witness a decline as well. Conversely, if a significant number of stocks register an increase, the index tends to rise.

In essence, the Dow Jones is a stock index that brings together 30 companies on the New York Stock Exchange (NYSE), excluding the transport and public services sectors. These selected stocks are commonly referred to as “blue chips,” signifying the most robust and stable companies in the market.

Calculating the Dow Jones stock index is not an easy task. The value is calculated as the sum of the stock prices of all the stocks in the index divided by a factor which changes sometimes (typically when a company in the index undergoes a stock split).

Calculation of the Dow Jones Industrial Average Index (DJIA)

The Dow Jones is calculated by adding the current stock prices of the 30 stocks that make up the index and then dividing the total by a factor. This factor, known as Dow Divisor, is constantly modified to account for events such as stock splits, spin-offs, or any similar structural changes within the constituent companies to ensure the continuity of the index. The divisor is adjusted such that the value of the DJIA is not directly affected by these corporate actions. This allows for a consistent, historical comparison of the index's value over time.

Dow Jones quote

Is investing in the Dow Jones Industrial Average worth it?

The decision to invest in the Dow Jones or any other stock index hinges on individual preferences, and here are some elements to consider:

  • Diversification: Opting to invest in Dow Jones offers some degree of diversification since the index represents a basket of 30 large companies from various sectors of the economy. This diversification can help mitigate the risk associated with investing in individual stocks or specific sectors. However, it's important to note that Dow Jones represents only a portion of the US stock market and does not provide complete diversification.
  • Stability and history: The Dow Jones is the oldest stock index in the world and is composed of established and long-standing companies. This can provide some degree of stability compared to other indices that may be more volatile or composed of younger companies. However, it is important to remember that even the companies in the Dow Jones can be subject to significant price fluctuations due to market events or economic conditions.
  • Past performance: Examining the past performance of the Dow Jones can provide an indication of historical trends. However, it is important to keep in mind that past performance is not a guarantee of future results. Financial markets are influenced by multiple factors, including the economy, interest policies, geopolitical events, and other unpredictable factors that can affect future performance.
  • Risk tolerance: Investing in the Dow Jones still carries some level of risk. Although the index is considered relatively stable, it can still experience price fluctuations and losses. It is important to assess your risk tolerance and make sure to adequately diversify your investment portfolio.

Performance and evolution of the Dow Jones

The Dow Jones was launched in 1885 and is one of the oldest stock indices in the world. Over the years, it has undergone several changes in the composition of its constituent companies. Initially, it was composed of 12 companies, but in 1928 it went to 30, the same as today.

Over the years, it has recorded an overall positive trend, with periods of stable growth and others of volatility. During bull markets, the index has reached new all-time highs, highlighting the positive performance of the companies included in the index.

Dow Jones Industrial Average (DJIA) is one of the main global indices, but it is not the only relevant one. Various other indices represent different dimensions of the global economy.

Undoubtedly, the most important stock market index in the United Kingdom is the FTSE 100, often colloquially referred to as the “Footsie.” This index comprises the 100 companies with the highest market capitalisation listed on the London Stock Exchange. These companies represent about 80% of the entire market capitalisation of the exchange, making the FTSE 100 a significant indicator of the health of the UK stock market

In the United States, the Russell 2000 index tracks 2000 small-cap companies, providing a good indication of the performance of smaller businesses in the U.S.

NASDAQ Composite includes all the stocks listed on the NASDAQ stock exchange, many of which are tech companies. However, it also includes companies from other sectors.

Euro Stoxx 50 index tracks the performance of 50 large, blue-chip companies from 12 Eurozone countries.

DAX 30 tracks the 30 major German companies trading on the Frankfurt Stock Exchange, while CAC 40 tracks the 40 largest French stocks based on the Euronext Paris market capitalisation and IBEX35 tracks the 35 largest Spanish stocks.

Advantages and disadvantages of investing in the Dow Jones Industrial Average Index

The Dow Jones index offers advantages to many subjects associated with the world of finance and capital markets. But there are also some disadvantages and limitations of the Dow that it is important to know.

Advantages of investing in DJIA

  • Convenient performance benchmark: The Dow Jones serves as a convenient and widely recognised performance benchmark, providing an easy way to track the overall health and performance of the US stock market. Its simplicity makes it a popular choice for investors to gauge the market's direction.
  • Provides historical context: With its more than 120-year history, the Dow Jones offers valuable historical data for analysis. This extensive historical context can assist investors in making informed decisions, especially for those with long-term investment horizons.

Disadvantages of investing in DJIA

  • Focus on large companies: One limitation of Dow Jones is that it focuses solely on large companies. Consequently, it fails to represent the entire US stock market, which includes small and mid-cap stocks.
  • Limited number of stocks and sectors: The Dow Jones only tracks 30 US stocks, and it does not cover all sectors of the economy comprehensively. For instance, while it includes 9 sectors, it excludes the transportation and utilities sectors, limiting its representation of the overall market.
  • Price-weighting can be misleading: The Dow Jones is a price-weighted index, meaning stocks with higher prices have a more significant impact on the index's movement, irrespective of the actual size or influence of stocks with lower prices. This price-weighting mechanism can sometimes lead to a distorted perception of market movements.

Dow Jones summary

In conclusion, investing in the Dow Jones Industrial Average Index comes with the advantage of a widely recognised performance benchmark and a rich historical context. However, its limitations, such as focusing solely on large companies, tracking a limited number of stocks and sectors, and the potential for misleading price-weighting, should also be considered when making investment decisions.

It is crucial for investors to assess their individual investment goals and preferences before choosing to invest in this index or considering alternative options that may provide a more comprehensive view of the overall market.


Can investing in the Dow Jones Index be a reliable long-term investment strategy?

Investing in the Dow Jones Index can be a viable long-term investment strategy for many investors. Over its long history, the Dow Jones has demonstrated an overall positive trend with periods of growth and volatility.

How are companies selected to be part of the Dow Jones Index?

The selection of companies for the Dow Jones Industrial Average (DJIA) is not governed by a strict, quantitative rule-based process. Instead, it's a subjective process managed by the editors of The Wall Street Journal, which is published by Dow Jones & Company.

Does Dow Jones contain the 30 largest companies by market capitalisation?

No, while the DJIA consists of 30 companies, these companies are not necessarily the 30 largest by market capitalisation. Some very large companies are not included in the DJIA if their stock price is too low or if they are in a sector already adequately represented in the index.
