In the world of finance, you’ll often hear people ask, «How did New York do today?» or «How did the market perform today?» In both cases, these people are likely referring to the DJIA, as it is the most widely-used index. It is more popular than both the S&P 500 Index, which tracks 500 stocks, and the Nasdaq Composite Index, which includes more than 2,500 U.S. and international equities.

It is easy to confuse Dow Jones with the Dow Jones Industrial Average (DJIA). Often referred to as «the Dow,» the DJIA is one of the most-watched stock indexes in the world, containing companies such as Apple, Boeing, Microsoft, and Coca-Cola. Many critics of the Dow argue that it does not significantly represent the state of the U.S. economy as it consists of only 30 large-cap U.S. companies. They believe the number of companies is too small and it neglects companies of different sizes.

So a higher percentage move in a higher-priced component will have a greater impact on the final calculated value. At the Dow’s inception, Charles Dow calculated the average by adding the prices of the 12 Dow component stocks and dividing by 12. Over time, there were additions and subtractions to the index that had to be accounted for, such as mergers and stock splits. A stock market index is a mathematical construct that provides a single number to measure the overall stock market (or a selected portion of it).

An index tries to model a particular industry or market—or even entire national economies.

Price weighting with regular divisor adjustments does enable the Dow to reflect the market sentiments at a broader level, but it does come with a few criticisms. Sudden price increments or reductions in individual stocks can lead to big jumps or drops in DJIA.

Now assume that another company C lists on the stock exchange at the price of $10 per share on the fourth day.

Dow Jones — DJIA — 100 Year Historical Chart

In the early 20th century, the performance of industrial companies was typically tied to the overall growth rate in the economy. That cemented the relationship between the Dow’s performance and the overall economy. Even today, for many investors, a strong-performing Dow equals a strong economy while a weak-performing Dow indicates a slowing economy. In the case of (2), the net sum price change was 0 (stock A had +5 change, while stock B has -5 change, making the net sum change zero). Investors may own a handful of stocks within their investment portfolio in which they track each stock’s individual performance. However, the performance of a small portfolio is not indicative of the overall market.

It is an index that helps investors determine the overall direction of stock prices. The DJIA launched in 1896 with just 12 companies, primarily in the industrial sector. Since then, it’s changed many times—the very first came three months after the 30-component index launched. The first large-scale change was in 1932 when eight stocks in the Dow were replaced. As the economy changes over time, so does the composition of the index.

Assuming that stocks A and B maintain their earlier day prices of $30 and $85. This would not be a very useful reflection of the overall health of the market. Unlike both the S&P 500 and the Dow, the Nasdaq 100 contains some foreign companies and is heavily skewed to tech companies. For these reasons, the Nasdaq 100 may reveal less about the overall U.S. stock market and tell you more about the economic performance of the global tech industry.

The DJIA is considered a bellwether of the stock market and the U.S. economy as a whole. Although investors can’t invest directly in the index, they can park their money in a mutual fund or ETF that tracks the performance of the Dow Jones. The above cases cover many possible scenarios for changes for price-weighted indexes like the Dow or the Nikkei. The Dow divisor is adjusted to ensure events such as stock splits don’t change the numerical value of the DJIA.

Issues with market representation

When the Dow goes up, it is considered bullish, and most stocks usually do well. When the Dow falls, it is bearish, and most stocks typically lose money. The DJIA initially launched with just 12 companies based mostly in the industrial sectors. The original companies operated in railroads, cotton, gas, sugar, tobacco, and oil.

AB index wants to expand and increase the number of constituents from two to three, to include the newly listed C company stock in addition to the existing A and B stocks.

Assume that stock A is trading at $20 per share and stock B is trading at $80 per share on day 1. This difference in price weighting versus market-capitalization weighting can cause the DJIA to be more volatile than the S&P 500 in the short term.

An index can provide a measurable and traceable number that represents the overall market, a selected group of stocks, or a sector.
