Charles H. Dow, together with Edward Jones and Charles Bergstresser, founded Dow Jones & Company, Inc. in 1896. At this time, Dow developed the Dow hypothesis, which is a trading approach. Dow elaborated on his proposal in a series of Wall Street Journal editorials he co-founded and published.

Throughout the idea's more than a century of existence, William Hamilton, Robert Rhea, E. George Shaefer, and Richard Russell made significant contributions. In addition, Richard Russell and E. George Shaefer made substantial contributions throughout the 1960s. Even though the emphasis on transportation (or railways in its original form) has faded in recent years, the foundation of Dow's study continues to be important in today's financial markets.

As a result of Charles Dow's death in 1902, the whole market theory could not be published; instead, his pupils and collaborators utilized the editorials to publish books.

Dow Jones Transportation Average (DJTA)


The Dow Jones Transportation Average (DJTA), which is a price-weighted average of the stock prices of twenty publicly-listed transportation businesses in the United States, is calculated as follows: With the Dow Jones Transportation Average, Charles Dow, a co-founder of Dow Jones & Company, established what is now the country's oldest stock index in 1884, making it the country's oldest stock index.

At its inception, the index included nine railways and just two non-railroad companies.

During the late nineteenth and early twentieth century, railways dominated the transportation industry in the United States, particularly in the West. Aircraft, trucks, ships, delivery services, and logistics organizations have been included in the index, which now covers railways.

The DJTA's significance to the wider stock market has waned in recent years. However, transportation-related equities may be defying the general market trend and rising in value. Traders and investors may turn to them for aid in anticipating market changes.

According to proponents of the Dow Theory, the Dow Jones Transportation Average is a good indication of the state of the United States economy. A similar trajectory to the Dow Jones Industrial Average is predicted to be followed when manufacturing and transportation equities increase and transportation stocks decrease, respectively (DJIA). If there is a divergence, a trend reversal may be on the horizon.

Historically, economic downturns have been accompanied by a decrease in the DJIA but an increase in the DJTA. According to some estimates, aggregate demand declines due to divergence in the flow of manufactured items and their conveyance.

The DJTA reached a new high of $12,917 on December 9th, 2020, just a few months after dipping below 6,800 in March 2020 due to worries about the coronavirus (COVID19), which decimated aviation firms during a severe bear market. Until February 2020, the Dow Jones Industrial Average (DJIA) will continue to set new highs and record lows. Further evidence in favor of the Dow Theory was the disparity between the DJTA and the DJIA before the financial meltdown.

Dow Jones Industrial Average (DJIA)

The Dow Jones Industrial Average (DJIA) is a stock market index that measures the performance of 30 giants, publicly-traded blue-chip businesses on the New York Stock Exchange (NYSE) and the Nasdaq Stock Market (Nasdaq). The Dow Jones index was named after Charles Dow, a business colleague of Edward Jones who founded the index in 1896 and inspired the index's name.

It is the second-oldest stock market index in the United States, after only the Dow Jones Transportation Average (DJTA), which has been in existence since 1896.

The DJIA was created to serve as an indicator of the overall health of the United States economy. The DJIA, sometimes known as "the Dow," is one of the most closely followed stock market indices globally. Many blue-chip companies are included in the Dow Jones Industrial Average, all of which have a lengthy history of consistent growth.

When the index was initially launched in 1896, there were just 12 firms included in it. During that period, the United States was home to various industries.

During the first half of the twentieth century, the success of industrial enterprises was often related to the general growth rate of the economy. This resulted in a more direct correlation between the success of the Dow and the status of the economy overall. For many investors, substantial Dow numbers are seen as a sign of a healthy economy to invest in (while a weak-performing Dow indicates a slowing economy).

As the economy grows, the index's composition changes over time to reflect this shift. If a company is withdrawn from the Dow Jones Industrial Average and its name is changed to represent current economic developments, this is known as renaming.

If a company's stock market value plummets substantially due to financial issues, the Dow Jones Industrial Average may eliminate it from consideration. To determine the value of a firm, you multiply the number of shares in circulation by the current market price of the company's stock.

Companies with higher share prices are given a more significant index weight and vice versa. A higher cost of a costly component has a more substantial influence on the project's estimated value than an increase in a less expensive part. Charles Dow calculated the average stock price of the Dow's first twelve components by adding up and dividing by twelve the stock prices of the Dow's first twelve components. The final score was a simple average of all participants' scores. Many factors, like mergers and stock splits, have contributed to the index's variation during its history. It was out of date to be using mean calculations at this point.

Dow Divisor

The Dow Jones Industrial Average comprises many components, one of which is known as the Dow divisor (DJIA). The DJIA index value is calculated by multiplying the stock prices from each of the DJIA's 30 members by a divisor. However, business activities such as dividend payments and stock splits are reflected in the divisor regularly, as is the case with the stock market.

When dealing with a price-weighted stock market index such as the DJIA, index divisors are often used to decrease the complexity of the index value.

Because of the index's historical continuity, which has been disrupted by multiple stock splits, spinoffs, and changes to its components since its inception in 1896, the Dow divisor is employed to preserve its historical continuity. When a stock splits and dividend adjustments occur, the Dow divisor is used to ensure market stability by taking these events into consideration (or payments).

In the absence of variations in the Dow's divisors, the real numerical value of the DJIA remains constant. Throughout the years, the Dow divisor's value has seen significant fluctuations due to robust market moves. It reached a high of 16.67 in 1928 before plummeting to 0.147 in September of the current year.

As of December 2021, each Dow Jones index has its divisor; nevertheless, the DJIA's divisor is 0.15172752595384, which is the divisor for the DJIA as a whole.

In many cases, the index's total price is influenced by events such as stock splits and revisions to its list of member businesses, among other things. In these instances, adjustments are made to the Dow's divisor to maintain consistency between the quotes immediately before and after the event.

The value of a company's divisor decreases as more and more corporations undertake stock splits and spinoffs to minimize its divisor's weight. The DJIA's arithmetic average was computed by dividing the number of DJIA businesses by the initial number of DJIA firms. A manual adjustment has been made to guarantee that the DJIA is priced accurately in light of recent market occurrences.

In 1986, the divisor went below the 1.0 mark for the first time. Currently, the index has a divisor that is less than one, indicating that the index is greater than the sum of the prices of its constituent parts. As a result, the multiplier has been turned into a divisor rather than another way around.

Components of The Dow Theory


1. Trends will continue indefinitely unless and until a significant reversal befalls.

Even in the face of popular belief, primary trend reversals are occasionally misinterpreted as secondary trend reverses. While it may be challenging to detect a possible comeback in a bear market, the Dow hypothesis advises caution in the absence of clear indicators of such a turnaround, which may be tough to distinguish.

2. Each Category of Market Trends Have Three Phases.

If the Dow hypothesis is correct, it would be reasonable to anticipate a significant trend to go through three distinct stages. The following three phases occur accumulation, public involvement (or important movement), and excess during a bull market. These phases are referred to as the "distribution phase," the "public engagement phase," and the "panic phase" in a bear market, respectively.

3. Everything in the Market is at a discounted price.

According to the efficient markets hypothesis, while assessing asset values, all relevant information is considered. For example, this strategy would not be supported by a behavioral economics approach.

Even though not everyone is aware of them, market characteristics such as profits potential, competitive advantage, and managerial expertise are still present. Even in the most severe manifestations of this philosophy, future events are neglected on the pretense of risk to the individual.

4. Indexes that are out of sync will no longer function properly.

To establish a trend, the Dow-hypothesized indexes or the market averages must agree with one another. So the signals on one index must match the signals on the other index to be effective. Investors should be cautious if one statistic, such as the Dow Jones Industrial Average, shows the beginning of a new strong upswing while another measure stays in a severe drop.

That is because Dow believed that if business circumstances were excellent, as an increase in the DJIA would show, railways would benefit from transporting the freight necessary by this economic activity, which led to the DJIA and DJTA. If asset values continue to rise as railways continue to shrink simultaneously, the situation becomes unsustainable. Aside from that, if railways are profitable yet the market declines, no trend can be seen in either direction.

5. Market Trends Can Be Divided into Three Categories.

Bull and bear markets in the primary market might last for many months or perhaps a year or more. It is usual for secondary trends to arise inside more significant trends, with the second movement often running in opposition to the more significant trend. As an example of secondary trends, a pullback or rebound in reaction to a bear market, or vice versa, would be appropriate. Other noise patterns are only present for a brief period, usually less than three weeks.

6. It is expected that the volume will grow if the trend continues.

Volatility should rise in tandem with price movement in the direction of the fundamental trend and fall in tandem with price movement in the opposite direction of the fundamental trend. The absence of activity shows that the trend is deteriorating. When the price rises and falls during secondary pullbacks in a bull market, the volume should climb as the market continues to increase. If volume increases during a downturn, it's conceivable that the trend is reversing as more market participants become pessimistic due to this.

Things to Consider


When the market fails to produce another following peak and trough in the primary trend direction, this is a reversal in the primary trend. Specifically, the inability to set a new high followed by the difficulty of constructing a new lower low would signal the uptrend's reversal. Briefly stated, we have seen a shift in the long-term pattern of the market, from a time of constantly increasing highs and lows to a period of gradually declining highs and lows in recent years.

It is possible to reverse a negative trend if the market no longer falls to lower lows and higher highs. As a result of an upward trend, the market generates a higher peak than the previous peak and a lower dip than the last trough.

Signals and Identification of Trends

Trend reversals are one of the most challenging aspects of using Dow theory, and it is one of the most time-consuming. Because a Dow theory trader only trades in one way, recognizing when that direction switch is critical to becoming a successful trader in the long run.

When it comes to identifying trend reversals, the Dow hypothesis mainly depends on peak-and-trough research. The highest and lowest prices in a market are referred to as the market's peak and trough, respectively. In general, the Dow theory asserts that the market does not move in a straight line but instead oscillates between high points (peaks) and low points (troughs) rather than in a straight line (troughs).

The Dow hypothesis describes an ascending trend as a sequence of higher-and-higher peaks and peaks, with each successive rise becoming higher and higher. Peaks and troughs that are smaller in magnitude suggest a downward tendency.

According to the sixth Dow theory concept, until there is strong evidence that the trend has reversed, there will be no shift in the direction. Newton's first rule of motion holds that item inaction has a natural tendency to proceed in a straight line until it is stopped by an external force that causes it to deviate from its route. Unless a sufficiently substantial factor, such as a change in business, drives the market's primary trend to reverse, the market will continue to proceed in the same direction.

Closing Prices and Line Ranges

The closing prices of the index were more critical to Dow than the index's intraday volatility, which was of little consequence. If you want to use a trend indicator, the closing price, not the intraday price change, indicates the current trend.

To understand Dow theory, you must first understand a line range, which is often referred to as a trading range in other branches of technical analysis. Trading in these horizontal price swings should only be done after the trend line has been breached and only after assessing the direction of the market's movement. If the price passes the line, it is projected that the market will increase.


According to the Dow Theory, the market will rise if one of the market averages exceeds a prior significant high and is preceded or followed by an increase in the other average. The concept of efficient markets claims that everything is discounted to the lowest possible price. Until the trend is reversed, several market indices must confirm one another in terms of price and volume patterns to survive.

The Dow Jones Transportation Average (DJTA), a price-weighted average of the stock prices of 20 transportation companies, comprises 20 transportation enterprises. Aircraft, trucks, ships, delivery services, and logistics organizations have been included in the index, which now covers railways. According to proponents of the Dow Theory, the Dow Jones Transportation Average is a good indication of the state of the United States economy. The most prevalent reason for DJTA modifications is the result of an acquisition or other significant change in the central business.

The Dow Jones Industrial Average (DJIA), a blue-chip stock index in the United States, is highly respected. This price-weighted index, which is listed on the New York Stock Exchange and the Nasdaq, comprises 30 large publicly traded corporations.

Between 1884 and 1896, Charles Dow developed these indexes to proxy the American economy.
