What Is an ETF?
Educational only — not financial advice. Updated 2025.
1. What Is an ETF?
An exchange-traded fund (ETF) is a basket of securities—typically stocks or bonds—that trades on an exchange like a stock. Unlike mutual funds, ETFs trade throughout the day at market prices. They give investors easy access to diversification and professional index tracking without the high fees of active management.
2. How ETFs Work
Most ETFs track an index such as the S&P/TSX Composite or the S&P 500. The fund holds the underlying securities and issues shares that represent fractional ownership of the portfolio. The ETF’s market price typically stays close to its net asset value (NAV) through the create-and-redeem mechanism involving large institutional participants.
3. Benefits of ETFs
Low cost, transparency, and liquidity are the main advantages. Many broad-market ETFs charge expense ratios below 0.10%. They are tax-efficient because fund managers rarely sell holdings, minimizing capital gains distributions.
4. Types of ETFs
Core categories include equity ETFs, bond ETFs, commodity ETFs, and specialty or thematic ETFs. Some track global or sector indexes, while others pursue strategies such as dividends, ESG screening, or factor investing.
5. Risks to Understand
Although diversified, ETFs still carry market risk. Bond ETFs are subject to interest-rate risk, while niche thematic funds can be volatile. Always check liquidity and bid-ask spreads, especially for small or thinly traded funds.
6. How to Buy ETFs
ETFs are purchased through a brokerage account—Questrade, Wealthsimple, Interactive Brokers, or any bank discount broker. Investors typically use limit orders and avoid buying during the first or last 15 minutes of trading to reduce spreads.
7. Building an ETF Portfolio
Beginners often start with one 'all-in-one' ETF that automatically manages allocation between stocks and bonds. Alternatively, combine a Canadian equity ETF, a U.S. equity ETF, an international ETF, and a bond ETF for a simple, globally diversified portfolio.
