What Is the Dow Jones? Stock Market Indexes

To better understand how the Dow changes value, let’s start at its beginnings. When Dow Jones & Co. first introduced the index in the 1890s, it was a simple average of the prices of all constituents. 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.

Investors may (and in many cases should) choose to analyze and compare multiple indices to gain a more comprehensive understanding of the market and make better informed investment decisions. The US30, representing the Dow Jones Industrial Average, is not directly controlled by any single entity. It is a market index that reflects the collective performance of its 30 component stocks. However, Dow Jones & Company, the publisher of the index, determines the composition of the Dow Jones Industrial Average and calculates its value using a specific methodology.

In this manner, a company with a higher stock price but a smaller market cap would have more weight than a company with a smaller stock price but a larger market cap, which would poorly reflect the true size of a company. A part of the Dow may be dropped when a company becomes less relevant to current trends of the economy, to be replaced by a new name that better reflects the shift. For instance, a company may be removed from the index when its market capitalization drops because of financial distress. 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). Assume that stock A is trading at $20 per share and stock B is trading at $80 per share on day 1. In overseas trading, stock markets across the Asia-Pacific region turned in a mixed performance on Friday.

2. However, it’s important to note that not all companies in the DJIA can be categorized as blue-chip stocks.

5. Charles Dow, Edward Jones, and Charles Bergstresser formed the company in the 19th century.
6. Critics also believe that factoring only the price of a stock in the calculation does not accurately reflect a company, as much as considering a company’s market cap would.

The Dow was created by Charles Dow, and Edward Jones, co-founders of Dow Jones & Company. The index was initially designed to provide a snapshot of the performance of the industrial sector, which played a vital part of the American economy at that time.
