History of the Founding of Dow Jones

Dow Jones isn’t just one person, but rather two of the three founders of Dow Jones & Company, established in 1882. Charles Dow is the “Dow” in Dow Jones, Edward Jones is the “Jones,” and Charles Bergstresser is the third co-founder of the company.

In 1889, they founded The Wall Street Journal, which remains one of the most influential financial publications in the world today.

Charles Dow’s Contribution

Charles Dow was known for his ability to simplify complex financial news for the public. He believed investors needed a straightforward benchmark to indicate whether the stock market was rising or falling.

Dow selected several industrial-based stocks for the first index, with the first reported average being 40.94. He also believed that stock market movements could be predicted based on the price movements of different types of stocks.

According to the Dow Theory, a rising trend in industrial stocks should be confirmed by a similar upward movement in transportation stocks. Charles Dow created various market averages to better define the movement of “industrial stocks” or “transportation stocks.”

What is the Dow Jones Industrial Average (DJIA)?

The Dow Jones Industrial Average (DJIA) is the world’s oldest and most well-known stock market index, created by Charles Dow and Edward Jones in 1896.

Initially, the index was designed to reflect the state of the U.S. economy by observing the performance of 12 major industrial companies.

Today, the DJIA includes 30 large, diversified companies from various economic sectors, not limited to just the industrial sector.

History and Evolution of Dow Jones

Here is a summary of the history and development of Dow Jones that is important to understand.

Initial Companies in the DJIA

The DJIA was originally launched with just 12 companies, mostly from the industrial sector. However, it has since expanded to include 30 companies.

These initial companies were involved in industries such as railroads, cotton, gas, sugar, tobacco, and oil.

The performance of industrial companies was often seen as a reflection of the overall economy, making the DJIA a primary indicator of broader economic health.

Changes in the DJIA

Although changes in companies listed on the DJIA are rare, replacements sometimes occur to ensure the index continues to reflect current economic relevance.

Companies that no longer represent modern economic dynamics can be replaced by those more aligned with industry developments and market trends.

These changes keep the DJIA an accurate benchmark for U.S. economic health and reflect the sectors most influential in driving the economy.

How is Dow Jones Calculated?

The Dow Jones index is calculated based on the stock prices of the companies listed in it. However, its value is not solely dependent on individual stock prices; those prices are divided by a figure known as the “divisor.”

Price-Weighted Method

The Dow Jones is calculated using a price-weighted method, where stocks with higher prices have a larger impact on the index value.

Dividends and stock splits for stocks in the index also affect its value, causing constant fluctuations. This method is known as the price-weighted method.

Factors Affecting the DJIA Value

A drop in the Dow Jones index usually occurs when the stock prices of several companies in the index decline. Significant drops in the index tend to happen when there are major changes in stock prices.

A decline in the index can also occur due to an overall weakening of economic conditions. Factors such as oil price drops, economic crises, natural disasters, and more can contribute to such declines.
