Frequently Asked Questions

What is the biggest advantage of ETFs?

Low cost is the biggest advantage. Broad market ETFs charge as little as 0.03% annually — over 30 years, the difference between 0.03% and 1.00% fees can compound to hundreds of thousands of dollars on a large portfolio.

What is the biggest disadvantage of ETFs?

For passive index ETFs, the biggest disadvantage is that you are guaranteed to slightly underperform the index after fees. You cannot beat the market with an index fund. For active investors, this is a meaningful trade-off.

Are ETFs riskier than mutual funds?

ETFs and mutual funds tracking the same index carry identical market risk. The intraday trading ability of ETFs can encourage emotional trading, which is a behavioral risk. However, structurally, ETFs are not more risky than comparable mutual funds.
