Investing in exchange-traded funds starts with opening a brokerage account, choosing the right funds, and placing a trade. The entire process can take less than an hour, and many brokerages let you start with as little as $1. ETFs bundle dozens or hundreds of stocks or bonds into a single investment you can buy and sell on a stock exchange, giving you broad diversification without picking individual securities.
Open a Brokerage Account
You need a brokerage account to buy ETFs. Major online brokerages like Fidelity and Charles Schwab have no account minimums, meaning you can open one without depositing any money upfront. Several platforms, including Fidelity, Robinhood, and SoFi, also offer fractional shares, so you can invest in an ETF for as little as $1 or $5 rather than paying the full share price.
When choosing a broker, look for commission-free ETF trading, which is now standard at most major platforms. You’ll also want a clean interface for researching funds, access to a wide selection of ETFs, and the account type you need. If you’re investing for retirement, you can open a traditional or Roth IRA at the same brokerage. For general investing with no withdrawal restrictions, a standard taxable brokerage account works.
To open the account, you’ll typically need your Social Security number, a government-issued ID, and a linked bank account for transfers. Most applications are approved within minutes.
Decide What Type of ETF Fits Your Goals
ETFs come in many varieties, and the right one depends on what you’re trying to accomplish. The most common categories include:
- Broad stock market ETFs track indexes like the S&P 500 or the total U.S. stock market, giving you exposure to hundreds or thousands of companies in one fund.
- International ETFs hold stocks from companies outside the U.S., covering developed markets, emerging markets, or both.
- Bond ETFs invest in government or corporate bonds and tend to be less volatile than stock ETFs, making them useful for balancing risk.
- Sector ETFs focus on a specific industry like technology, healthcare, or energy.
- Dividend ETFs target companies that pay regular dividends, which can provide income alongside growth.
If you’re just getting started and want a simple, long-term approach, a broad U.S. stock market ETF paired with an international ETF covers a lot of ground. Adding a bond ETF gives you a classic three-fund portfolio that many investors use as a core strategy for decades.
Evaluate an ETF Before You Buy
Not all ETFs tracking the same index are created equal. A few key metrics help you separate strong funds from weaker ones.
The expense ratio is the annual fee the fund charges, expressed as a percentage of your investment. Low-cost equity ETFs typically charge no more than 0.25%, and many broad index ETFs charge as little as 0.03%. Bond ETFs often come in under 0.20%. These fees are deducted automatically from the fund’s returns, so you never see a separate bill, but they compound over time. On a $10,000 investment earning 7% annually, the difference between a 0.03% fee and a 0.50% fee adds up to thousands of dollars over 30 years.
Tracking difference measures how closely an ETF follows its benchmark index. A fund tracking the S&P 500 should deliver returns very close to the actual S&P 500. Larger gaps suggest the fund is less efficient at replicating the index, often because of higher costs or poor management.
Assets under management and average daily trading volume tell you how popular and liquid a fund is. Larger, more heavily traded ETFs tend to have tighter bid/ask spreads, which is the small gap between the price buyers are willing to pay and the price sellers are asking. A wide spread means you’ll pay slightly more when buying and receive slightly less when selling. For most well-known ETFs, spreads are tiny, but they can be meaningful for niche or thinly traded funds.
Place Your First Trade
Once you’ve funded your account and chosen an ETF, buying shares takes just a few clicks. You’ll search for the fund by its ticker symbol (a short abbreviation like “VTI” or “SPY”), enter the number of shares or dollar amount you want to invest, and select an order type.
A market order executes immediately at the current price. It guarantees your order goes through but not the exact price you’ll pay, since the price can shift slightly between the moment you submit and the moment the trade fills. A limit order lets you set the maximum price you’re willing to pay. The trade only executes at that price or lower. Limit orders give you more control, especially for ETFs with lower trading volume or during volatile market hours.
For large, heavily traded ETFs, market orders work fine for most investors. If you want a bit more price protection, setting a limit order a few cents above the current ask price ensures execution while capping your cost. Avoid placing trades right at market open (9:30 a.m. Eastern) or in the final minutes before close, when prices tend to be more volatile and spreads can widen temporarily.
Build a Position Over Time
You don’t need to invest a large sum all at once. Many investors use dollar-cost averaging, which means investing a fixed amount on a regular schedule, say $200 every two weeks. This approach smooths out the effect of price swings because you buy more shares when prices are low and fewer when prices are high.
Most brokerages now let you set up automatic recurring investments into specific ETFs. You pick the fund, the dollar amount, and the frequency, and the platform handles the rest. Fractional share support makes this seamless because your entire $200 goes to work even if a full share costs $450.
Reinvesting dividends is another way to grow your position without extra effort. When an ETF pays a dividend, you can have your brokerage automatically use that cash to buy more shares of the same fund. This compounds your returns over time.
Why ETFs Are Tax-Efficient
ETFs have a structural advantage over mutual funds when it comes to taxes. Most mutual funds must sell securities internally to accommodate investors redeeming their shares, and those sales can generate capital gains that get passed along to every shareholder, even if you didn’t sell anything yourself. You could owe taxes on gains you never personally realized.
ETFs sidestep this problem through a mechanism called in-kind redemptions. When large institutional investors want to exit an ETF, they exchange shares for the underlying securities directly rather than triggering a sale. This means ETFs rarely distribute capital gains to shareholders. The majority of ETFs are also passively managed, tracking an index rather than actively buying and selling. Less trading inside the fund means fewer taxable events.
This doesn’t mean ETFs are tax-free. You’ll still owe taxes on dividends the fund pays out and on any capital gains when you eventually sell your shares at a profit. But the year-to-year tax drag is typically much lower than with an actively managed mutual fund, which makes ETFs especially effective in taxable brokerage accounts.
Keep Your Portfolio on Track
After your initial investment, the main ongoing task is rebalancing. Over time, different parts of your portfolio grow at different rates. If stocks surge and bonds lag, your portfolio might drift from your intended mix of, say, 80% stocks and 20% bonds to something like 90/10. Rebalancing means selling a bit of what’s grown and buying more of what’s lagged to get back to your target.
How often you rebalance is up to you. Checking once or twice a year is enough for most people. Some brokerages offer automatic rebalancing tools, particularly within retirement accounts. The goal isn’t to time the market but to keep your risk level consistent with your original plan.
