How the Dow Jones Industrial Average (DJI) Is Calculated

The Dow Jones index (DJI) is a stock market measure of the price of stocks. However, unlike many other stock market measures, it does not use weighted arithmetic average. Instead, it is based on a composite price of each stock in the index, divided by its divisor. As a result, a single point movement in any of the component stocks will move the index by the same amount.

Price-weighted index

Price-weighted index is a stock market index in which each component contributes a fraction of the total index value proportionate to its price. The index’s price changes from day to day and over time, this value can change wildly. To better understand this type of index, let’s look at how price-weighted indexes are calculated. In a nutshell, price-weighted indexes take into account the volume and profitability of the stocks that comprise it.

A price-weighted index measures the overall health of the economy and demonstrates which stocks are a good long-term investment. It is an excellent tool for portfolio diversification, as it shows where the market is headed. This type of index has several advantages and disadvantages. Listed below are some of the advantages of a price-weighted index. The advantages: Price-weighted indexes provide a more accurate picture of how a market will react to certain conditions.

How a price-weighted index works is by dividing total index prices by a divisor. The divisor is an arbitrary value calculated by the index to account for changes in the composition of the index. The Dow Jones Industrial Average uses a divisor, which varies over time. In addition to this, the Divisor can change as stock splits occur, as well as stock price changes. In addition, price-weighted indexes are often more sensitive to changes in the prices of higher-priced stocks than lower-priced ones.
