The Dow Jones and S&P 500 are two of the most widely followed indexes in the trading world. Each has its place, with the S&P 500 providing a broader view of the economic performance across the US, and the Dow Jones focusing on a smaller group of influential companies, most of which are involved in industry and manufacturing in some way. Both are excellent tools for traders and can be used as a way to make trades through a Dow Jones broker.
One advantage of the Dow Jones is that, due to the smaller number of Dow Jones companies, a tracker ETF will usually have exposure to a fuller list of Dow stocks compared to the S&P 500.
