INVESTING BASICS

Exchange traded funds (ETFs) have become a widely discussed type of investment fund in global financial markets. Data published by organizations such as the Investment Company Institute shows that exchange traded funds ETFs have grown in number, variety, and assets over the past two decades, alongside traditional mutual funds and index mutual funds. This growth has coincided with increased access to online trading platforms, expanded stock exchanges, and broader availability of financial data.

Understanding how ETFs work may require examining several interconnected components, including holdings, pricing mechanisms, and tracking error. These elements help explain how ETF shares are created, how ETFs trade during the trading day, and why an ETF's market price may differ from its net asset value NAV.

This article provides an overview of how ETFs work, how they compare with mutual funds, and how exchange traded funds may function within an investment portfolio. The discussion focuses on structure and mechanics rather than outcomes, and references historical practices where relevant.

Exchange Traded Funds: An Overview

Exchange traded funds can be described as investment funds that trade on stock exchanges and hold baskets of underlying securities. Historical data from organizations such as the Investment Company Institute suggests that ETFs have grown alongside mutual funds as commonly used financial products. Their structure can influence how pricing, holdings, and trading activity occur during a trading day. Understanding how ETFs work may help readers interpret publicly available information about ETF shares, market prices, and net asset value (NAV).

Key Takeaways

• ETFs may combine features of stocks and mutual funds
• ETF shares trade on stock exchanges during the trading day
• Pricing can differ from net asset value
• Holdings can include various asset classes
• Creation and redemption may affect supply

How Do ETFs Work?

ETFs are a type of investment fund that can hold collections of underlying assets such as individual stocks, bonds, or futures contracts. Unlike mutual funds, which typically process mutual fund trades once per day, ETFs trade on stock exchanges throughout the trading day, similar to an individual stock. This trading structure can influence how ETF share prices relate to the net asset value of the fund.

ETFs work through a process known as creation and redemption. Large financial institutions, often referred to as market makers or authorized participants, may assemble baskets of underlying securities and exchange them with an ETF provider for new ETF shares. This process can also operate in reverse, where ETF shares are returned, and the underlying assets are distributed. This mechanism may help align an ETF's market price with its net asset value over time.

The net asset value represents the market value of an ETF's underlying assets minus liabilities, divided by the number of outstanding shares. While NAV is calculated periodically, ETFs trade at current market prices that can fluctuate based on supply and demand. As a result, an ETF's market price could trade at a premium or discount relative to NAV.

Many ETFs are designed to track broad market indices, particular sectors, or specific asset classes, such as bond ETFs or commodity ETFs. Others may be actively managed, where a portfolio manager adjusts holdings based on an investment objective. Management fees and operating costs, often expressed as a management expense ratio, are deducted from the fund's assets and can affect long-term returns based on past data.

Common Benefits of ETFs

Financial experts often describe several characteristics that exchange traded funds may exhibit. These features have been observed across many ETFs, though outcomes can vary by fund structure, asset class, and market conditions.

Diversification Through A Single Trade

• ETFs can hold baskets of underlying securities, which may include equities, bonds, or other instruments.
• This pooled structure has historically allowed exposure to multiple holdings through one transaction.
• Diversification ETFs may reduce concentration in a single issuer, although diversification does not eliminate market or asset-specific risk.

Cost Efficiency

• Data indicates that management fees and operating costs for many passive ETFs have generally trended lower than those of actively managed funds over time.
• Passively managed ETFs and index ETFs, in particular, have historically reported lower management expense ratios than many traditional mutual funds.
• Costs can still vary depending on asset classes, active management, and trading activity.

Liquidity And Intraday Tradability

• ETFs trade on stock exchanges throughout the trading day, allowing ETF shares to be bought or sold at current market prices.
• Liquidity can depend on trading volume, underlying assets, and overall stock market conditions.
• In some cases, bid-ask spreads may widen during periods of market stress, based on prior market observations.

Transparency Of Holdings

• Many ETFs publish holdings on a daily basis, which has historically provided visibility into underlying assets.
• Transparency practices can differ, particularly for actively managed ETFs, where disclosures may occur less frequently.

Access To Different Asset Classes And Sectors

• ETFs have historically provided exposure to a wide range of asset classes, including bond ETFs, commodity ETFs, and funds tracking international stocks or particular sectors.
• This access has expanded over time as ETF providers introduced products tied to broad market indices and market sectors.

Caveats

• Liquidity, pricing, and transparency may vary by fund and market conditions.

ETF Investments: Key Risks To Understand

Several risks can be associated with exchange traded funds. These risks can vary by fund structure, asset class, and market conditions.

Market Risk And Sector Concentration

• ETFs can be exposed to broad market movements, as their market value may fluctuate with changes in the stock market or bond market.
• Funds focused on a particular sector or industry may experience higher volatility than those tracking broad market indices, based on past performance patterns.
• Sector concentration has historically increased sensitivity to economic or regulatory events affecting specific market segments.

Tracking Error Vs. Tracking Difference

• Tracking difference refers to the historical difference between an ETF's performance and that of its underlying index, often influenced by management fees, operating costs, and portfolio holdings.
• Tracking error measures the variability of that difference over time.
• For example, an index ETF may show small but persistent deviations from index returns due to expenses or sampling methods, as documented in prior ETF studies.

Liquidity And Bid-Ask Spreads

• ETF liquidity can depend on both trading volume of ETF shares and liquidity of underlying securities.
• During periods of market stress, bid-ask spreads have historically widened for some ETFs, reflecting higher transaction costs.
• Bond ETFs and commodity ETFs, in particular, have shown variations in liquidity during volatile markets, according to regulatory reviews.

Leverage And Inverse Funds

• Leveraged ETFs and inverse ETFs typically aim to reflect a multiple or opposite of a benchmark's daily performance.
• Due to daily rebalancing and compounding effects, returns over longer periods may differ from the benchmark's cumulative return.
• For example, periods of high volatility have previously resulted in outcomes that diverged from simple multiple assumptions.

Currency Risk

• ETFs holding international stocks or foreign assets may be affected by currency exchange rate movements.
• Past performance of international ETFs indicates that currency fluctuations can either increase or reduce returns when measured in domestic currency.

Counterparty And Derivatives Considerations

• Some ETFs use derivatives such as futures contracts or swaps to gain exposure.
• These structures may introduce counterparty risk, where outcomes depend on the ability of another party to meet obligations.
• Regulatory filings have historically highlighted this risk for certain commodity ETFs and synthetic structures.

Common Types Of ETFs

Exchange traded funds have developed into a broad range of structures over time, and may fall into more than one category, depending on the ETF's investment objective, underlying assets, and management approach.

Index ETFs

Index ETFs are designed to track the performance of a stated index, such as broad market indices or specific benchmarks. Past data indicates that these ETFs typically follow published index methodologies and adjust holdings as index components change.

Equity ETFs/Stock ETFs

Equity ETFs can hold baskets of individual stocks and may focus on broad markets, particular sectors, or specific styles such as growth or value. Sector-focused equity ETFs have historically reflected trends within defined market segments.

Bond ETFs/Fixed Income ETFs

Bond ETFs may invest in government, corporate, or municipal bonds, as well as bonds with different maturities. Historical observations suggest that bond ETFs can experience price changes related to interest rates, credit conditions, and bond market liquidity.

Commodity ETFs

Commodity ETFs can provide exposure to commodities through physical holdings or derivatives such as futures contracts. Regulatory disclosures indicate that returns have historically been influenced by commodity prices, storage costs, and futures market dynamics.

Currency ETFs

Currency ETFs may track the value of one or more foreign currencies relative to another currency. Past performance data shows that these ETFs can reflect foreign exchange movements and may be affected by interest rate differentials and monetary policy changes.

Actively Managed ETFs

Actively managed ETFs allow portfolio managers to make discretionary decisions about holdings. Transparency and trading frequency can vary, depending on regulatory requirements and fund structure.

Cryptocurrency/Crypto-Asset ETFs

Cryptocurrency ETFs, where permitted by jurisdiction, may hold digital assets directly or gain exposure through futures-based structures. Prior regulatory approvals and market data indicate that availability and structure have differed across regions and time periods.

Inverse ETFs

Inverse ETFs are structured to target the opposite of a benchmark's daily performance. Daily reset mechanisms can lead to outcomes over longer periods that differ from simple inverse assumptions.

Leveraged ETFs

Leveraged ETFs seek to provide a multiple of a benchmark's daily return. Past performance records indicate that compounding effects and volatility have influenced longer-term results.

Asset Allocation ETFs

Asset allocation ETFs typically hold combinations of other ETFs or asset classes within a single fund. Typically, allocations are periodically adjusted according to predefined rules or management discretion.

Alternative ETFs

Alternative ETFs may include exposures such as managed futures, long/short equity, or other non-traditional approaches. Regulatory disclosures indicate that these ETFs can use derivatives and may behave differently from traditional equity or bond funds.

ETFs Compared: Fees & Costs In Canada

Fee disclosures and historical fund documents show that exchange traded funds in Canada can involve several types of costs. These costs may vary by fund, provider, and online trading platform.

MER Vs. Management Fee

• The management expense ratio (MER) reflects the total annual operating costs of an ETF, expressed as a percentage of net asset value.
• The management fee is one component of the MER and typically covers portfolio management and administrative services.
• Additional expenses, such as custody and regulatory fees, can contribute to the difference between the management fee and the MER.

Trading Commissions

• Trading commissions may apply when ETF shares are bought or sold through a brokerage account.
• Commission structures have varied over time and across financial institutions, based on publicly available fee schedules.
• Some platforms have historically offered commission-free ETF trades, though this feature has not been universal.

Bid-Ask Spread And Implicit Costs

• The bid-ask spread represents the difference between the buying and selling prices of an ETF on a stock exchange.
• This spread has historically reflected liquidity, trading volume, and underlying market conditions.
• Wider spreads may increase transaction costs, particularly during periods of market volatility.

Operating Expenses And Other Considerations

• ETFs can incur operating expenses related to index licensing, portfolio rebalancing, and regulatory compliance.
• Funds using derivatives, such as commodity ETFs or certain bond ETFs, have historically reported additional costs related to contract rollover and counterparty arrangements.
• Taxes at the fund level, where applicable, may also influence net returns based on past disclosures.

Cost Disclosure Note

• Costs can vary by fund and platform.
• Canadian regulators require standardized disclosure through ETF Facts documents, which summarize fees, expenses, and trading costs based on historical data.

Canada Callout: ETF Facts

Final Thoughts on ETFs

ETFs have evolved into a widely used type of investment fund, offering access to a range of underlying securities, asset classes, and market sectors. ETFs may provide diversification through a single trade, intraday tradability, and transparency of holdings. At the same time, ETF investors may encounter risks related to market volatility, tracking error, liquidity, leverage, currency exposure, and derivative structures.

Fees and costs, including management expense ratios, trading commissions, and bid-ask spreads, have historically influenced net outcomes, and documents such as ETF Facts in Canada have provided standardized summaries of holdings, costs, and risk ratings. Evaluating features such as weighting methodology, underlying assets, liquidity, and distribution policies has historically helped contextualize how ETFs have functioned in past market conditions.

Overall, ETFs can be considered a versatile financial instrument that has historically reflected both the dynamics of the underlying markets and the operational structure of the funds themselves.
