How Does an ETF Differ From a Mutual Fund?
Both ETFs and mutual funds pool investor money to hold diversified portfolios. The key difference is how they trade. Mutual funds price once per day after market close and you buy or sell at that price. ETFs trade continuously on exchanges like stocks, so prices fluctuate throughout the day. ETFs also tend to have lower minimum investments and are more tax-efficient due to lower portfolio turnover.
What Types of ETFs Are Available?
The ETF universe has expanded dramatically beyond simple index trackers. Today you can find broad market ETFs, sector ETFs (technology, healthcare, energy), bond ETFs, international ETFs, commodity ETFs, dividend ETFs, and factor ETFs targeting value or growth stocks. There are also leveraged and inverse ETFs, which are complex instruments designed for sophisticated traders and generally unsuitable for long-term investors.
What Are the Tax Advantages of ETFs?
ETFs are generally more tax-efficient than mutual funds due to a unique creation and redemption mechanism. When investors sell ETF shares, they typically sell to other market participants, not back to the fund. This structure means ETFs rarely need to sell underlying securities, resulting in fewer taxable capital gains distributions compared to actively managed mutual funds that frequently buy and sell holdings.
Frequently asked questions
Can ETFs go to zero?
A broadly diversified ETF tracking hundreds of companies is extremely unlikely to go to zero, as that would require every company in the index to fail simultaneously. However, narrow sector ETFs or leveraged ETFs can lose most of their value. Stick to broadly diversified ETFs for core long-term holdings.
What is the bid-ask spread and does it matter for ETFs?
The bid-ask spread is the difference between the price buyers will pay and the price sellers will accept. For widely traded ETFs on major indices, spreads are typically tiny — often a penny or less. For thinly traded niche ETFs, spreads can be wider and represent a hidden transaction cost. Check daily trading volume before buying an ETF.
