Dow Jones Industrial Average Reaches New High

- The Dow Jones Industrial Average was first calculated on May 26, 1896, and initially consisted of just 12 companies, including now-unfamiliar names like the American Cotton Oil Company and the Tennessee Coal, Iron and Railroad Company. It expanded to 30 companies on October 1, 1928, and continues to track 30 stocks today. - Unlike market-capitalization-weighted indices such as the S&P 500, the DJIA is price-weighted. This means stocks with higher share prices have a greater impact on the index's value, regardless of the company's overall size. - A figure called the "Dow Divisor" is used to calculate the index, which helps maintain consistency through events like stock splits, spin-offs, and component changes. The value of the index is the sum of the 30 stock prices divided by this factor. - The components of the Dow are selected by a committee composed of representatives from S&P Dow Jones Indices and The Wall Street Journal. The selection aims to represent the broader U.S. economy, covering all industries except for transportation and utilities, which have their own separate Dow Jones averages. - The makeup of the index evolves with the economy; for example, in March 2015, Apple Inc. replaced AT&T, and in July 2018, Walgreens Boots Alliance replaced General Electric, one of the original 1896 components. - The journey to its current level includes several major milestones. The Dow first closed above 1,000 on November 14, 1972, and surpassed the 10,000 mark for the first time on March 29, 1999. - Some analysts are forecasting continued growth, with certain predictions suggesting the DJIA could reach 50,000 by late 2027 and potentially approach 60,000 by the end of 2029.
