what is dow jones industrial average (djia)
Dow Jones Industrial Average The Dow Jones Industrial Average (DJIA), or simply the Dow (/ˈdaʊ/), is a stock market index that shows how 30 large, publicly owned companies based in the United States have traded during a standard trading session in the stock market.[3] The value of the Dow is not a weighted arithmetic mean[4] and does not represent its component companies' market capitalization, but rather the sum of the price of one share of stock for each component company. The sum is corrected by a factor which changes whenever one of the component stocks has a stock split or stock dividend, so as to generate a consistent value for the index.[5]
