There are nearly 1,000 exchange traded funds (ETFs) on the market today. Can you pick just one of them and get the exposure you need?

The idea behind owning different ETFs is that you want a variety of different types of investment exposure, says Dan Caplinger at the Motley Fool. If your holdings have a low correlation, it will give your portfolio a better chance of rising over time.

It is important to know what each and every ETF you want to hold owns. Which companies do they hold? At what weighting? This will help you realize which funds are simply overlapping and help you determine how diversified you are.
