SPDR Dow Jones Industrial Average ETF (NYSE: DIA)

This is a plain vanilla ETF. There is nothing fancy about it; it simply tracks the performance of the Dow Jones Industrial Average, net of expenses. Basically, you’re investing in a portfolio of the top 30 industrial stocks in the U.S. Although all the components of the Dow are here, they are not equally weighted. Goldman Sachs is the largest holding at 8.34% followed by Microsoft (6.5%), and UnitedHealth Group (6.03%).
