Are ETFs a Safe Investment?
Explore the ETF, its pros and cons, how it compares to other investments, best practices, and why it’s considered one of the safest investment vehicles around

ETFs have rapidly become one of the most popular choices for Canadian investors, especially those just getting started. Because of their simple diversification, low costs, and trading flexibility, they’re widely regarded by investors as low-risk investments, making them a strong addition to most portfolios. But low risk doesn’t mean risk-free, so how safe are ETFs really?
We'll explore the ins and outs of ETFs, including how they work, behave, and compare to other investments. Recognizing the risks before you invest can set you up for success as you build your portfolio. Let’s dive in!
What is an ETF?
An exchange-traded fund (ETF) is a type of investment fund that holds a basket of assets, such as stocks, bonds, or commodities. Similar to mutual funds, ETFs let you invest in a wide range of securities with a single purchase, offering immediate, built-in diversification. Shareholders don’t directly own these underlying assets but instead own a portion of the fund that invests in them.
ETFs are traded on stock exchanges, meaning investors can buy and sell them at market prices any time throughout the trading day. There are also several types of ETFs, which can be categorized by asset type or investment strategy—most aim to track the performance of a specific market index, industry, or theme. Although many investors appreciate the variety of ETFs and their broad mix of assets, some choose not to use them since the holdings can’t be personalized.
As one of the largest ETF providers in Canada, BMO offers ETFs to suit every investor’s unique needs.
The risks of ETFs
ETFs are generally considered low-risk investments, but it’s still possible to lose money if you’re not careful. So, before putting money into one, it’s important to understand those risks and how to mitigate them.
→ Subject to market fluctuations
Market volatility can significantly impact the value of your investments, and ETFs are no exception. Since they track different markets, sectors, and indexes, their value mirrors the performance of those benchmarks, for better or for worse. For example, an ETF that tracks the S&P 500 will decline in value if the S&P 500 falls.
→ Concentration risk
While many ETFs spread their holdings across multiple industries and asset classes, some focus solely on a specific sector, theme, or commodity. If that segment struggles, your ETF may see a sharp decline. Unless your portfolio is otherwise diversified, this concentration can effectively put all your eggs in one basket, leaving you overexposed to one area.
→ Tax considerations
Tax efficiency is often highlighted as a major benefit of ETF investing, but tax treatment is more nuanced than many investors realize. As such, it’s important to understand how any ETF you invest in may generate taxable income or gains. The tax risks an ETF faces largely depend on:
- The type of account it’s held in (registered vs. non-registered)
- How actively it’s managed
- How frequently it trades
- Its structure
- Whether it holds international securities, derivatives, or commodities
→ Trading risks
Investors often appreciate that ETFs can be bought and sold throughout the market day like stocks, but this can be a double-edged sword. It may encourage more frequent trading, which can add costs and risk to your portfolio. Additionally, more specialized or niche ETFs trade at lower volumes, making them costlier to buy and sell, particularly in large quantities.
→ Potential for tracking error
While most ETFs aim to track an index, they don’t always reflect its performance perfectly. The mismatch between the returns of an ETF and its target index is known as tracking error. It’s usually quite small, but it can still catch even the savviest of investors off guard. Fees, fund management decisions, and market conditions can all contribute to tracking error, so it’s worth reviewing an ETF’s historical data before investing.
Are ETFs safer than other investments?
ETFs have a reputation for being safer than many individual securities, and for good reason. Offering diversified exposure across many holdings, an ETF effectively cushions the impact when a singular asset in the basket doesn’t perform well.
However, the level of risk you take on will vary depending on the ETF you choose. Some are designed to be conservative, while others are meant for growth and come with higher risks. Let’s take a closer look at how ETFs compare to other common investments.
ETFs vs. stocks
While both stocks and ETFs are subject to market risk, their level of volatility typically differs significantly. Since it can rise or fall sharply based on company news and market conditions, a stock has the potential for higher returns than an ETF but also represents greater risks. On the other hand, ETFs usually hold dozens or even hundreds of stocks, which helps offset ups and downs and reduce risk.
For example, imagine having shares in an individual tech company versus owning an ETF that broadly reflects the performance of the entire tech industry. If that one company struggles, your stock could plummet in value. In contrast, the ETF may dip as well, but its diversification across multiple businesses can help cushion the impact of that single company’s decline.
ETFs vs. mutual funds
Mutual funds and ETFs are similar in that they both pool investor money to buy a diversified mix of securities. Since they usually invest in many different assets, they tend to be less volatile than individual investments, which can help reduce risk.
However, a major difference is how they trade. Like stocks, ETFs are bought and sold on an exchange throughout the day, while mutual funds are priced and traded only once per day after the market closes. ETFs are also often passively managed, while mutual funds are typically actively managed and therefore tend to have higher fees.
As for which vehicle is safer, there’s no definite answer, because the risk level of both is largely dependent on the assets that each fund holds and its investment strategy.
When ETFs are the riskier choice
A large component of an ETF’s risk is its direct relationship to the market it tracks. If the target theme, sector, or index it follows performs poorly, the ETF will usually decline as well. This makes them riskier than products like GICs, high-interest savings accounts, or government bonds, which offer greater principal protection and more predictable returns. However, the trade-off is that ETFs provide more potential for long-term growth.
Are ETFs safe during market downturns?
ETFs are not immune to downturns, as they are designed to track market performance. For instance, if a broad equity market drops by 25%, an ETF tracking that market will likely fall by a similar amount. That said, diversified ETFs can still make downturns easier to weather than holding securities, because the poor performance of a single holding has less impact on a well-spread portfolio.
Some ETFs also focus on “defensive sectors,” which have historically shown stronger resilience during economic recessions. These include health care, utilities, and consumer staples. Other ETFs hold bonds or cash-like investments, which may fluctuate less than stocks during periods of market volatility. Investors can also help smooth out short-term price swings through dollar cost averaging, which involves investing a fixed dollar amount at regular intervals over time.
Ultimately, your level of risk during a downturn depends on the type of ETF you hold, the assets and sectors it tracks, how diversified it is, and your overall investment strategy.
How to trade ETFs
Trading ETFs is a relatively simple process. You can buy or sell them through a direct investing platform or with help from a financial advisor. Robo-advisors are another beginner-friendly option, as they can build and manage a portfolio for you based on your risk tolerance and goals.
Before placing any trades, be aware that ETFs may involve trading fees and ongoing expense ratios, as well as any fees for advisory services. Note that when buying or selling, you can choose a “market order” to execute immediately at the current price, or a “limit order” to specify the price you’re willing to pay or accept.
Here are some best practices to help you as you begin trading ETFs:
- Clearly define your goals and risk tolerance
- Reduce tax pressures by holding ETFs in registered accounts (TFSA, RRSP, FHSA, etc.)
- Avoid emotional selling when markets are down
- Consider investing a fixed amount regularly (dollar-cost averaging)
- Keep a diversified portfolio and rebalance it periodically

Wrapping up

Of course, like any investment tied to market performance, they can still lose value. However, by understanding what you’re investing and committing to a goal-oriented strategy, you can limit the potential risks and take advantage of the many benefits.
ETF risks FAQs
Yes, it’s possible to lose money on ETFs. The underlying assets, sectors, or indexes they track can lose value due to market shifts, causing the ETFs themselves to dip as well. However, the right investment strategies can smooth out volatility and reduce risk.
When an ETF closes, the fund provider typically liquidates its assets and distributes the proceeds to remaining shareholders based on the value of their holdings. If the ETF is held in a taxable account, investors may owe taxes on any capital gains realized when redeeming shares or receiving the proceeds.
You can buy and sell ETFs at any time during regular market hours. Orders placed after hours will typically be executed as soon as the market reopens.
Generally speaking, ETFs are often safer than individual stocks because they spread your money across multiple holdings. This diversification helps reduce the impact on your portfolio if a single company underperforms.
