The Namesake of the Dow Jones Industrial Average (DJIA)
The Dow Jones Industrial Average (DJIA), commonly known as the Dow, is a stock market index that measures the performance of 30 prominent companies listed on stock exchanges in the United States. Its creation in 1896 by Charles Dow, co-founder of Dow Jones & Company, and statistician Edward Jones, marked a significant milestone in the history of financial markets.
