The Dow Jones Industrial Average (DJIA) is simply an index that reflects the average price of the 30 stocks within it.
As such, it isn't possible to buy shares of DJIA itself.
However, there are ways to invest your money in investment products that mirror the DJIA index. Here in RoboMarkets Blog you can learn more about how to invest in dow jones.
Instead of buying stocks in one company, mutual funds allow you to diversify your portfolio. You pool your money with other investors to buy lots of securities.
The risk is less since you can invest in hundreds or even thousands of securities at the same time. If one security performs poorly, others can offset the risk.
