What Are ETFs and How Do They Work?
Exchange-Traded Funds (ETFs) are investment vehicles that trade on stock exchanges, similar to individual stocks. They pool investor capital to purchase a diversified portfolio of assets, which can include stocks, bonds, commodities, or a mix of various asset types. ETFs offer the dual benefits of mutual funds' diversification and individual securities' trading flexibility.
Traded on stock exchanges, ETFs experience price changes throughout the day, making them a versatile option for professional investors. They have revolutionised the investment landscape since their inception in the 1990s.

This concise video explains the fundamental structure of ETFs, their core benefits, and the key differences between passive and active management approaches.
ETFs are designed to track specific indexes, sectors, or investment strategies. For instance, an ETF might follow the S&P 500, giving investors exposure to the largest companies in the U.S. Alternatively, ETFs can focus on niche markets or specific sectors, such as technology or healthcare, providing targeted investment opportunities.
Why are ETFs becoming more popular?
Exchange-Traded Funds have transformed the investment landscape over the past three decades. These versatile instruments combine the diversification benefits of mutual funds with the trading flexibility of individual securities, creating an efficient vehicle for accessing global markets.
The ETF industry has experienced remarkable expansion, with global assets under management reaching $15.1 trillion in 2024, driven by investor demand for transparency, cost efficiency, and portfolio flexibility. The market is projected to potentially double by 2030, reflecting the growing recognition of ETFs as essential portfolio building blocks.
Today's ETF marketplace offers unprecedented choice. Investors can access traditional equity and fixed income markets alongside emerging themes in technology infrastructure, clean energy transition, and specialist sectors. This breadth enables precise portfolio construction aligned with specific investment objectives and risk parameters.
Core Benefits of ETF Investing
Combine the diversification benefits of mutual funds with the trading flexibility of individual securities, ETFs can be bought and sold daily, just like a stock.
They are cost efficient and have lower fees than most other managed funds.
ETFs help spread investment risk because they can invest in a range of global investments.
ETFs are also very transparent, you can see what's held in the portfolio.
What fees do ETFs charge?
There is a charge by the ETF provider for management and administration, expressed as a percentage of assets. Fees generally range from 0.03% for passive index-tracking ETFs to over 1% for actively managed or specialised ETFs.
Are active ETFs expensive?
While active ETFs do carry higher fees than passive ETFs, they typically cost substantially less than traditional actively managed mutual funds. Their simpler operational structures and trading through stock platforms drives down costs while maintaining active management capabilities. This makes professional active management accessible at more reasonable price points than historically available. Active ETFs may also benefit from structural tax advantages in many jurisdictions.
The ETF Market in Numbers
The ETF industry continues its remarkable growth trajectory, driven by investor recognition of the structure's advantages.
Diverse Types of ETFs and Their Strategic Uses
The ETF market is vast and varied, offering professional investors a plethora of options to align with their strategic goals.
- Index ETFs: Track a specific market index such as the S&P 500 or Nasdaq 100, delivering broad market exposure for investors aiming to mirror market performance.
- Sector and Industry ETFs: Focus on sectors like technology, energy, or healthcare, helping investors capitalise on sector-specific trends.
- Bond ETFs: Provide exposure to government, municipal, or corporate bonds for investors seeking regular income.
- Commodity ETFs: Track the price of commodities such as gold, oil, or agricultural products, offering a hedge against market volatility.
- Currency ETFs: Track currency pairs, enabling investors to speculate on foreign exchange movements.
- Inverse and Leveraged ETFs: Use derivatives to deliver inverse or amplified returns, typically suited to short-term strategies executed by experienced investors.
Active vs. Passive ETF Management
The ETF universe encompasses both passive index-tracking strategies and actively managed approaches. Understanding their distinct characteristics helps investors select appropriate tools for portfolio construction.
The Active Management Resurgence
Active ETFs have experienced significant momentum, with assets growing at 39% annually since 2019. This acceleration reflects several factors: improved ETF regulatory frameworks enabling sophisticated strategies, active managers converting mutual funds to the ETF structure for its tax advantages, and investor demand for strategies that can navigate market dispersion. In 2024, active ETFs attracted nearly one-quarter of industry flows despite representing less than one-tenth of assets, signaling a structural shift in how active strategies are accessed.
Understanding Costs and Fees Associated with ETFs
While ETFs are known for their cost efficiency, it is essential for investors to be aware of the associated costs:
- Expense Ratios: Annual fees charged by the ETF provider for managing the fund, typically lower for passive ETFs and higher for specialised or active strategies.
- Commissions and Trading Fees: Some brokerages charge commissions for buying and selling ETFs, though many—including Schwab—offer commission-free trades on a wide range of products.
- Bid/Ask Spreads: The difference between the bid and ask price affects transaction costs; higher liquidity generally narrows spreads.
- Premiums and Discounts: ETFs can trade above (premium) or below (discount) their net asset value, so understanding pricing is key to minimising costs.
Navigating the Risks and Considerations When Investing in ETFs
Investing in ETFs is not without risks. Professional investors should be mindful of the following considerations:
- Market Volatility: ETF prices fluctuate with markets, and volatile periods can widen bid/ask spreads.
- Tracking Error: Performance can deviate from the target index because of fees, sampling methods, or trading costs.
- Liquidity: Niche or specialised ETFs may have lower trading volumes, leading to wider spreads and less efficient execution.
- Complexity: Leveraged and inverse ETFs employ sophisticated strategies that may not suit all investors without deep understanding of the underlying mechanics.
Practical Steps to Start Investing in ETFs
For professional investors looking to incorporate ETFs into their portfolios, the following steps provide a structured approach:
- Open a Brokerage Account: Choose a platform with wide ETF coverage, competitive fees, and robust research tools.
- Conduct Thorough Research: Use screeners and third-party research to evaluate objectives, expense ratios, and historical performance.
- Diversify Your Portfolio: Blend ETFs across asset classes, sectors, and geographies to mitigate risk and enhance returns.
- Monitor Your Investments: Review holdings regularly and stay current on market trends and economic developments.
- Develop an Exit Strategy: Set clear criteria for selling, such as target prices or evolving market conditions, to help maximise gains and limit losses.
Frequently Asked Questions
Common questions about ETF investing and how Fiducial Communications supports investment managers in communicating their ETF strategies.
What exactly is an ETF and how does it differ from a mutual fund?
An Exchange-Traded Fund is an investment vehicle that trades on stock exchanges throughout the day, much like individual shares. While both ETFs and mutual funds pool investor capital to purchase diversified portfolios, their operational mechanics differ significantly.
ETFs trade continuously at market-determined prices during trading hours, enabling intraday transactions.
Mutual funds execute all transactions at a single price calculated after market close.
This gives ETFs more flexibility and generally better tax efficiency due to their in-kind creation/redemption process. Most ETFs also disclose holdings daily, while mutual funds usually report quarterly.
Why are ETFs more cost-efficient than mutual funds?
The ETF creation and redemption process occurs in-kind, meaning authorized participants exchange baskets of securities rather than cash. This mechanism reduces transaction costs within the fund and enhances tax efficiency by minimizing capital gains distributions.
Passive ETFs benefit from lower portfolio management costs due to their systematic, rules-based approach. Without the need for extensive research teams and active decision-making infrastructure, expense ratios remain compressed.
Should I choose active or passive ETFs?
It depends on your investment goals:
Passive ETFs excel as core portfolio holdings, providing reliable, low-cost access to broad market exposure.
Active ETFs may add value in areas like emerging markets or specialised sectors where skilled managers can outperform.
Many investors mix both: passive for core exposure, active for targeted opportunities.
How does ETF liquidity work?
ETF liquidity operates on two levels.
Primary market liquidity comes from the creation and redemption mechanism, where authorized participants can create or redeem large blocks of shares. This process ensures the ETF's market price remains close to its underlying net asset value.
Secondary market liquidity refers to the ETF's trading volume on exchanges. While daily trading volume provides one liquidity indicator, the true liquidity depends more fundamentally on the liquidity of the underlying holdings.
For professional investors executing larger positions, understanding both liquidity layers matters. Working with brokers familiar with ETF trading mechanics can help achieve efficient execution, particularly in less actively traded funds or during volatile market conditions.
What are thematic ETFs?
Thematic ETFs focus on long-term trends such as AI, clean energy, cybersecurity, and genomics. They help investors target specific themes without picking individual stocks.
They work best as satellite positions, since they are more concentrated and can be more volatile.
By understanding the fundamentals of ETFs and leveraging their strategic benefits, professional investors can enhance their portfolios and achieve their investment objectives.
