What Are These Points That Dow Always Gaining or Losing?
The Daily News would not be complete without a report on the opening and closing of this market index. But while you’ve certainly heard reports about the Dow Jones Industrial Average (DJIA) going up or down a certain number of points, do you know what these points represent? Read on to find out how the Dow works and what changes mean for investors and the stock market.
However, because the Dow only consists of 30 different stocks, it is not the best representation of the entire market.1 sometimes investors are fooled into believing that if the Dow is up, so are all other stocks, but this is not the case.
The Down Jones Industrial Index is a list, or index, of companies considered as good indicators of the overall strength of the stock market. Simply put, these companies are a barometer of the market: when they do well, the economy is doing well, and vice versa. Therefore, the Dow takes the average value of these companies every day to see if it has risen or fallen.4 the DJIA is named after Charles Dow, who created it in 1896, along with his business partner, Edward Jones.5
Because the index is about companies worth billions of dollars, a simple method had to be formulated to show their changes in value. The clever and witty Charles Dow broke everything into points instead of dollars. The points still represent dollars, but the ratio is not 1: 1. In this way, instead of saying, “Today, Dow shares collectively earned $ 693.573961, give or take a few thousandths,” people can say, “the Dow rose 100 points.”2 Obviously, this is a big improvement.
Changes in the index over time
The index grew to 30 components in 1928 and has changed components a total of 51 times.6 7 the first change occurred just three months after the launch of the index.8 in its early years, until about the Great Depression, there were many changes in its components. In 1932, eight stocks within the Dow were replaced. However, during this change, Coca-Cola Company and Procter & Gamble Co. added to the index, two stocks that are still part of the Dow in 2019.9 10
The most recent large-scale shift to the Dow took place in 1997, when four of the index’s components were replaced. Two years later, in 1999, four more components of the Dow were changed. The most recent change took place on June 26, 2018, when Walgreens Boots Alliance, Inc. replaced General Electric Company.11 10
How does the Dow splitter work?
To better understand how the Dow changes value, let’s start with its beginnings. When Dow Jones & Co. The index first introduced in the 1890s, it was a” simple average ” of the prices of all components. For example, suppose there were 12 stocks in the Dow index; in that case, the value of the Dow would have been calculated simply by taking the sum of the closing prices of the 12 stocks and dividing it by 12 (the number of companies or “Dow index components”). Therefore, the Dow started as a simple average price index.12
To calculate the DJIA, the current prices of the 30 stocks that make up the index are added together and then divided by the Dow divider, which is constantly changing.13 to demonstrate how this use of the divider works, we will create an index, the Investopedia Mock Average (IMA). The IMA consists of 10 shares, which add up to $ 1,000 when you add up the prices of your shares. The IMA quoted in the media is therefore 100 ($1,000 ÷ 10). Note that the divisor in our example is 10.
Now, let’s say that one of the shares in the IMA average is trading at IM 100, but it undergoes a 2-by-1 split, reducing the price of its shares to $ 50. If our divisor remains unchanged, the calculation for the average would give us 95 (9 950 ÷ 10). This would not be accurate because the share split simply changed the price, not the value of the company. To compensate for the effects of splitting, we need to adjust the divider down to 9.5. In this way, the index remains at 100 (9 950 ÷ 9.5) and more accurately reflects the value of the stock on the average. If you are interested in finding the current Dow divider, you can find it on the website of Dow Jones Indexes and Chicago Board of Trade.
The value of the Dow divider has changed significantly over the years. For example, it was at 16.67 in 1928, but it was at 0.132129493 as of March 2011.14 the values of the Dow divider, as well as the dividers for the other Dow Jones Indices are published daily in The Wall Street Journal.
For example, if the sum of the prices of the 30 constituents of the DJIA is 1,650, dividing this figure by the Dow Divisor of 0.132129493 would provide a level of 12,487.75 for the index. As of September 1, 2017, the Dow Divisor was 0.14523396877348 on September 1, 2017. Using this Divisor, each cambio 1 change in price on a particular stock within the average equals a 6.885 point movement (or 1 ÷ 0.14523396877348).
Evaluation of the Dow Jones methodology
No mathematical model is perfect, each comes with its merits and demerits. Price weighting with regular divider adjustments allows the Dow to reflect market sentiment at a broader level, but it comes with some criticism.15 sudden price increases or reductions in individual stocks can lead to big jumps or falls in DJIA.
For a real-life example, a drop in AIG’s stock price from around $ 22 to $ 1.5 within a month led to a nearly 3,000-point drop in the Dow in 2008. Certain corporate actions, such as the dividend going ex (i.e. becoming an ex dividend, in which the dividend goes to the seller rather than the buyer), lead to a sudden drop in DJIA on the previous date. The high correlation between multiple components also led to greater price swings in the index. As illustrated above, this index calculation can be complicated in the settings and divisor calculations.
Despite being one of the most recognized and most followed indices, critics of the price-weighted DJIA index advocate the use of float-adjusted market value-weighted S & P 500 or the Wilshire 5000 index, although they also come with their own mathematical dependencies.3 16 17 18
After almost 140 years as a marker of the main developments in the market, the DJIA remains one of the most recognized and cited indices of all markets. While it may not represent new market opportunities and fast-growing companies in early stages, and may not be indicative of the overall economic strength of the U.S. economy given that many of the companies in the index acquire a high percentage of revenue outside the United States, it provides some valuable purposes. Therefore, for all its shortcomings, the Dow remains one of the most viewed indicators for the performance of the stock market and The Shape of the US.. economy.
