The Dow: 130 Years as the Original Index Icon
The Dow® has endured through more than half of U.S. history. Quoted far and wide from Wall Street to Main Street, The Dow is still the number that most investors cite when asked how the market is doing. Created on May 26, 1896, by Charles Dow as a way to gauge stock market performance and track trends in U.S. equities, this financial and cultural icon has weathered recessions, depressions, bubbles and expansions through 2 world wars, 2 global pandemics and 23 U.S. presidents.
The Dow’s longevity is not typical—it is exceptional—and it has been earned through sustained attention to governance, methodology and relevance. The Dow Jones Industrial Average (DJIA) started with 12 stocks, expanded to 20 in 1916 and reached its now-familiar count of 30 in 1928. It has remained a 30-stock index ever since.
As its publicly available methodology outlines, The Dow is price weighted, and its constituents are reviewed monthly for ongoing eligibility. There is no annual or semi-annual reconstitution of The Dow. Rather, changes in response to corporate actions and market developments can be made at any time. While stock selection is not governed by quantitative rules, a stock typically is added only if the company has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors. Maintaining adequate sector representation within the index is also a consideration in the selection process for The Dow. As a result…The Dow's 30 components are not a random sample—they are among the largest, most economically influential companies in the U.S. economy, selected by a committee specifically to reflect the breadth of industry in the U.S.
The length of The Dow’s live index history is extremely valuable. Investors don’t need to wonder how the U.S. equity market might have performed during significant market events over the past 130 years. Instead, they can use The Dow to see how the market did react to different environments, thereby helping investors around the world to contextualize U.S. equity market movements.
There have been nearly 140 constituent changes to The Dow since May 1896, reflecting how it evolves to track a changing market and the latest trends shaping it. The way in which The Dow is used has also evolved over its 130-year history. Beyond its role as a barometer for U.S. equity performance, The Dow has also come to serve as the underlying benchmark for various index-linked products around the world in recent decades, with an estimated USD 115 billion indexed or benchmarked to The Dow at the end of 2024. The Dow also has a robust trading ecosystem, promoting price transparency and market efficiency, with more than USD 8 trillion in index-equivalent trading volume in products linked to the index in 2024.
The Dow first closed above 1,000 in November 1972 after 76 years. It closed above 10,000 in March 1999—cutting a journey that once took 76 years into just over a quarter-century, a direct reflection of how compounding economic growth accelerates over time. On Feb. 6, 2026—just months before its 130th anniversary, The Dow closed above 50,000 for the first time. Each of these milestones is significant precisely because the record behind the index is so long. A benchmark that reaches 50,000 after five years of history is a data point. A benchmark that reaches 50,000 after 130 years of continuous stewardship is a statement about the trajectory of the U.S. economy itself.
