What You Need Before Buying ETFs
Buying an ETF is as straightforward as buying a stock. You place an order through a brokerage account, it executes on a stock exchange, and the shares land in your account. The entire process takes minutes once you're set up.
Before you buy your first ETF, you need two things: a brokerage account and a decision about which ETF to buy. If you're still learning what ETFs are, start with our beginner's guide to ETFs and come back when you're ready to take action.
Step 1: Open a Brokerage Account
A brokerage account is your gateway to buying ETFs. Most major brokers now offer commission-free ETF trading, no account minimums, and fractional shares. The top options include Fidelity, Charles Schwab, and Vanguard.
When choosing a broker, prioritize these features:
Commission-free ETF trading — nearly universal now, but verify before opening an account. Fractional shares — lets you invest any dollar amount, even if a single share costs $400. Research tools — quality screeners and fund data help you make informed decisions. Account types — make sure they offer the account type you need (taxable brokerage, IRA, Roth IRA).
Opening an account typically takes 10 to 15 minutes online. You'll need your Social Security number, a form of ID, and your bank details for funding the account. Most accounts are approved the same day.
Step 2: Fund Your Account
Link your bank account and transfer money into your brokerage. ACH transfers are free but take one to three business days. Wire transfers are faster but cost $15 to $25. Some brokers offer instant buying power while your transfer settles.
There's no magic number for your first deposit. With fractional shares, even $100 is enough to get started. If you're investing a larger amount like $1,000 or more, check out our guide to investing $1,000 in ETFs for specific allocation ideas.
Step 3: Choose Your ETF
This is the most important step. Browse the ETF Beacon directory to explore funds by category, type, and key metrics. For your first ETF, broad-market index funds are the strongest starting point.
Some solid first ETFs to research include VTI (Vanguard Total Stock Market), VOO (Vanguard S&P 500), or SPLG (SPDR Portfolio S&P 500). These offer instant diversification across hundreds or thousands of stocks at rock-bottom fees.
If you want to compare options, learn how to compare ETFs using metrics like expense ratio, tracking error, and liquidity. You can also use the ETF Beacon comparison tool to see funds side by side.
Step 4: Place Your Order
Now for the actual purchase. There are two main order types you should know about:
Market orders execute immediately at the best available price. They're simple and guaranteed to fill, but you won't know the exact price until after the trade. For highly liquid ETFs like SPY or VOO, market orders work fine.
Limit orders let you set the maximum price you're willing to pay. The trade only executes if the ETF can be bought at or below your limit price. This gives you more control and protects you from price spikes. For most investors, limit orders are the smarter default choice.
Set your limit price at or just above the current ask price for a quick fill. If you set it too low, your order may not execute.
When to Buy: Timing Tips for ETF Purchases
ETFs trade throughout the market day, from 9:30 AM to 4:00 PM Eastern. But not all times are equal. The best time to buy ETFs is during the middle of the trading day, roughly between 10:00 AM and 3:30 PM Eastern.
Avoid trading in the first and last 15 minutes of the day. During these windows, bid-ask spreads tend to widen, meaning you'll pay a higher effective price. This is especially true for international ETFs, bond ETFs, and smaller funds.
Also avoid buying ETFs on days with scheduled market-moving events (like Fed announcements) unless you're confident in your decision. Volatility spikes can temporarily push prices away from fair value.
Fractional Shares: Invest Any Amount
Fractional shares let you buy a piece of an ETF share rather than a whole one. If VOO trades at $430 per share but you only have $100 to invest, you can buy 0.232 shares. Most major brokers now support this feature.
Fractional shares are a game-changer for beginners because they remove the barrier of high per-share prices. You can build a diversified portfolio with any dollar amount and invest every penny rather than leaving cash sitting idle.
Dollar-Cost Averaging: The Stress-Free Approach
Rather than trying to pick the perfect moment to buy, consider dollar-cost averaging — investing a fixed amount on a regular schedule regardless of price. For example, investing $200 on the 15th of every month.
This approach removes emotion from the equation. You buy more shares when prices are low and fewer when prices are high, which naturally averages out your cost over time. Learn more about this approach in our guide to dollar-cost averaging into ETFs.
After You Buy: What to Do Next
Once your trade executes, you own ETF shares. Here's what to do next:
Turn on dividend reinvestment (DRIP). This automatically uses your dividend payments to buy more shares, compounding your returns without any effort. Most brokers offer this as a simple toggle.
Set up automatic investments. Schedule recurring purchases to build your portfolio consistently. Even small regular contributions compound significantly over decades.
Don't obsess over daily prices. ETFs are long-term investments. Checking your portfolio multiple times a day adds stress without adding returns. A monthly or quarterly check-in is plenty.
As your portfolio grows, you may want to add additional ETFs for broader diversification. When that time comes, our guide to building an ETF portfolio walks you through asset allocation and rebalancing strategies.
