Understanding ETFs
Exchange-traded funds now hold over $10 trillion in assets. Here’s what they are, how they work, and how to pick one.
What an ETF is
An ETF is a basket of securities you can buy and sell like a single stock. They typically track an index — the S&P 500, total U.S. bonds, MSCI EAFE — for a tiny expense ratio.
ETFs vs mutual funds
ETFs trade intraday, are usually more tax-efficient, and often have lower expense ratios. Mutual funds still shine for automatic investing and inside 401(k)s.
Frequently asked questions
What’s a good starter ETF?
Broad total-market ETFs (VTI, ITOT, SCHB) offer instant diversification for expense ratios under 0.05%.
