ETF (Exchange-Traded Fund)
A basket of stocks (or bonds, commodities) that trades on a stock exchange like a single stock. Most ETFs track an index.
An ETF is a fund — a basket of underlying assets — packaged so it trades on a stock exchange like a regular share. You can buy and sell ETFs throughout the day at the current market price. Mutual funds, by contrast, only trade at end-of-day net asset value.
Practically, the most common ETFs are index ETFs: VTI tracks the total US stock market, VOO tracks the S&P 500, VXUS tracks international stocks, BND tracks US bonds. Pick a handful that span the asset classes you want to own, and you have a complete portfolio with very low total expense ratios.
ETFs have a few advantages over mutual funds for most investors:
- Lower expense ratios on average (though not always)
- More tax-efficient structure — internal capital gains distributions tend to be smaller
- No minimums — you can own one share
The downside is that you can buy in middle-of-day prices that fluctuate, which encourages overtrading for some people. Set up automatic monthly purchases and you neutralise that.
For long-term investors, mutual funds and ETFs of the same underlying index are nearly interchangeable. Pick on cost and convenience.
