The Dow Jones Industrial Average (DJIA) is a stock market index that tracks the performance of 30 large, publicly traded companies listed on the New York Stock Exchange (NYSE) and the Nasdaq Stock Market. It is one of the most widely followed stock market indices in the world and is often used as a barometer of the overall health of the US stock market.
There are a few different ways to buy the Dow Jones Industrial Average. One way is to buy shares of an exchange-traded fund (ETF) that tracks the DJIA. ETFs are baskets of securities that trade on exchanges, just like stocks. Some popular ETFs that track the DJIA include the SPDR Dow Jones Industrial Average ETF (DIA) and the iShares Core S&P 500 ETF (IVV).
