It’s been around since 1896 and is comprised of America’s finest, largest, and most invested in blue chip companies. That makes it a hot topic of debate and, according to many pundits, a key barometer of the state of the overall stock market and economy. They talk about it on the television and in newspapers all the time, normally when discussing the performance of the stock market and the companies that drive the U.S. economy. The Dow Jones Industrial Average is a stock index of 30 U.S. blue-chip large-cap companies, which has become synonymous with the American stock market as a whole. The index, however, only has 30 companies, and the index itself is price-weighted, meaning that it does not always present an accurate reflection of the broader stock market. The DJIA is the second-oldest U.S. market index after the Dow Jones Transportation Average.
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 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.
Dow Calculation on Day 6
A price-weighted index uses the price per share for each stock included and divides the sum by a common divisor, usually the total number of stocks in the index. The Dow Jones Industrial Average (DJIA) is an example of a price-weighted index. When it was created in 1896 by Charles Dow, it was meant to reflect the average price of stocks in the marketplace. 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.

No mathematical model is perfect—each comes with its merits and demerits. 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. For a real-life example, an AIG stock price dip from around $292 to $45 within a month’s time led to a fall of almost 3,000 points in the Dow in 2008.

The Dow is also a price-weighted index as opposed to being weighted by market capitalization. This means that stocks in the index with higher share prices have greater influence, regardless if they are smaller companies overall in terms of market value.

Rather, it reflects the sum of the price of one share of stock for all the components, divided by the divisor. Thus, a one-point move in any of the component stocks will move the index by an identical number of points.
