The Dow Jones Industrial Average closed out a tumultuous 2020 by hitting a record high of over 30,600 points. It has since climbed even higher, leaving shareholders and analysts wondering how long the market can continue to rise before the next major sell-off.
Though the DJIA comprises only 30 stocks, it is often regarded as a gauge of American business and economic prosperity. At the time of this writing, the Dow Jones sits at just over 31,300, roughly triple its value from a decade ago.
The DJIA is a price-weighted average of 30 large American companies. The index currently contains companies such as the world’s largest retailer Walmart, media juggernaut Disney, global financial institution J.P. Morgan, aerospace and defense giant Boeing, and as of 2015, tech behemoth Apple.
The companies comprising the Dow change over time to reflect the changing economy. Since the creator of the index, Charles Dow, was also the founding editor of The Wall Street Journal, editors at the publication select the companies that comprise the index.
Since its inception in 1896, when only 12 companies were included in the average, the Dow has changed over 50 times. The last remaining company from the original list of 12, General Electric, was finally removed in June 2018. It was replaced with drugstore chain Walgreens Boots Alliance.
To determine the value of the Dow Jones Industrial Average the year you were born, 24/7 Wall St. reviewed daily Dow figures aggregated by economic research website Macrotrends.net. Historical Dow data are inflation-adjusted using annual headline CPI in chained 2018 dollars.
