Dow Jones Industrial Average

Charles Dow and one of his business associates, statistician Edward Jones, estimated it for the first time on May 26, 1896. It is the second oldest U.S. market index, however, its constituents have changed several times. Its objective was as simple as it was revolutionary: at the time, anyone interested in the stock market had to dig through multiple newspapers, journals, and rumors, which was a massive amount of information that was impossible to process. Dow and Jones created the averages to serve as a “market thermometer,” allowing a casual observer to see if the markets as a whole were going upwards or downwards on any given day.

The average is a weighted average that accounts for the variations in stock values across all the firms it follows and measures the change in the group as a whole, rather than a simple average of the prices of all of its constituents. The average serves as a reliable gauge of how the markets as a whole are functioning by selecting the biggest and most reliable firms in each of the major industrial sectors.

Despite the Dow’s small number of firms, it is made up of some enormous and dependable Blue Chip Stocks. The ups and downs of the Dow may be a very powerful predictor of investor mood throughout the whole economy since these companies have established their worth through time.
