The Role of ETFs in a Modern Investment Portfolio
Exchange-Traded Funds (ETFs) have become one of the most popular investment vehicles in recent years, thanks to their flexibility, low costs, and broad market exposure.
Whether you're a new investor or an experienced trader, ETFs can be a valuable addition to a diversified portfolio. In this article, we’ll explore how ETFs work, the different types of ETFs available, and provide examples of how to use them strategically in a modern portfolio.
What Are ETFs?
ETFs are investment funds that trade on stock exchanges, much like individual stocks. However, instead of representing ownership in a single company, ETFs typically hold a basket of assets, which could include stocks, bonds, commodities, or a combination of asset classes. Investors buy shares of an ETF, which gives them proportional ownership of the underlying assets. The price of an ETF fluctuates throughout the trading day, unlike mutual funds, which are priced at the end of the trading day.1
There are several key advantages to using ETFs:
Low Costs: ETFs typically have lower expense ratios than mutual funds because they are passively managed.
Liquidity: Since ETFs trade like stocks, they are highly liquid and can be bought or sold during market hours.
Diversification: ETFs offer instant diversification, as they hold a broad range of assets within a single fund.
Types of ETFs
There are many types of ETFs available, each catering to different investment goals and strategies:
Stock ETFs: These track an index like the S&P 500, NASDAQ, or Dow Jones. A popular example is the SPDR S&P 500 ETF SPY 0.00%↑, which tracks the S&P 500 and allows investors to gain exposure to a broad range of U.S. large-cap stocks.
Bond ETFs: These track bonds from governments, corporations, or municipalities. iShares U.S. Treasury Bond ETF GOVT 0.00%↑ is a commonly used bond ETF that gives exposure to U.S. Treasury bonds.
Sector and Industry ETFs: These focus on specific sectors or industries, like technology, healthcare, or energy. For instance, Technology Select Sector SPDR Fund XLK 0.00%↑ provides exposure to large-cap U.S. tech companies like Apple and Microsoft.
International ETFs: These invest in companies outside the U.S. Vanguard FTSE All-World ex-U.S. ETF VEU 0.00%↑ is a popular example, offering exposure to a broad range of non-U.S. stocks.
Commodity ETFs: These give exposure to physical commodities like gold, oil, or natural gas. SPDR Gold Shares GLD 0.00%↑ is an example of a commodity ETF, tracking the price of gold.
Thematic ETFs: These target specific investment themes like clean energy or artificial intelligence. For example, ARK Innovation ETF ARKK 0.00%↑ focuses on disruptive technologies across various sectors.
Using ETFs for Diversification
Imagine you’re a young investor with $10,000 to invest. You want exposure to the U.S. stock market, international stocks, and bonds. Instead of buying individual stocks and bonds, you could allocate your portfolio using ETFs:
60% in U.S. Stocks: Buy the Vanguard Total Stock Market ETF VTI 0.00%↑ to gain exposure to all U.S. publicly traded companies.
20% in International Stocks: Buy the iShares MSCI EAFE ETF EFA 0.00%↑ for exposure to developed markets outside the U.S.
20% in Bonds: Buy the iShares Core U.S. Aggregate Bond ETF AGG 0.00%↑ for broad exposure to U.S. investment-grade bonds.
This diversified ETF portfolio gives you access to thousands of individual securities across different asset classes, sectors, and geographic regions, without having to manage each investment individually.
How to Use ETFs in Your Investment Strategy
Core and Satellite Approach: Many investors use a "core and satellite" strategy, where they build a core portfolio with broad market ETFs like the Vanguard S&P 500 ETF VOO 0.00%↑ and supplement it with satellite positions in sector or thematic ETFs. This strategy allows you to benefit from broad market exposure while targeting specific growth areas.
Cost-Efficiency: ETFs typically have lower fees than mutual funds, which can significantly reduce costs over time. For example, the Vanguard Total Stock Market ETF VTI 0.00%↑ has an expense ratio of just 0.03%, compared to the average mutual fund expense ratio of around 1%. Over a 30-year period, this difference can result in substantial savings.
Tax Efficiency: Because ETFs are passively managed and have lower turnover, they tend to be more tax-efficient than mutual funds. Investors typically only incur capital gains taxes when they sell their shares, as opposed to mutual funds, which may trigger capital gains distributions.
ETFs are a powerful tool for investors looking for low-cost, diversified, and flexible investment options. Whether you’re seeking broad market exposure or targeting specific sectors or themes, there is an ETF to meet your needs. By incorporating ETFs into your investment strategy, you can build a well-diversified portfolio with minimal effort and cost.2
