Why You Need an ETF Screener
With over 3,000 ETFs available in the US, finding the right one by browsing randomly is like searching for a needle in a haystack. An ETF screener lets you filter this universe down to a shortlist of funds that match your specific criteria — category, fees, size, and performance — in minutes.
Whether you're building your first portfolio or adding a new position, using an ETF screener is the most efficient way to identify candidates. The ETF Beacon directory functions as a screener, letting you sort and filter the entire ETF universe.
Step 1: Define What You're Looking For
Before you touch any filters, answer one question: what role will this ETF play in your portfolio? Common roles include broad US stock exposure, international diversification, bond allocation, sector bets, or income generation.
Your answer determines which category and asset class to filter for. Without a clear purpose, you'll waste time scrolling through irrelevant funds. If you need help defining your portfolio structure, our portfolio building guide is a good starting point.
Step 2: Filter by Category and Asset Class
The first filter narrows the universe from thousands of ETFs to dozens or hundreds. Category groups ETFs by what they invest in — US large-cap, international, bonds, commodities, sectors, and so on.
On ETF Beacon, you can browse by category or type to find funds in your target area. Start broad. If you want US stock exposure, begin with all US equity ETFs before narrowing to a specific type like S&P 500 or total market.
Step 3: Set an Expense Ratio Maximum
The expense ratio filter is your best friend. Set a maximum to eliminate expensive funds that eat into your returns. Good thresholds by category:
Broad index ETFs: Maximum 0.10%. The best ones charge 0.03%. If you're paying more than 0.10% for an S&P 500 or total market fund, you're overpaying.
Sector and thematic ETFs: Maximum 0.50%. Specialized strategies cost more, but there's no reason to pay above 0.50% for most sector funds.
Active and alternative ETFs: Maximum 0.75%. Actively managed funds charge more, but the fee needs to be justified by the strategy's added value.
Understanding why fees matter is crucial. Our expense ratio guide shows how even small fee differences compound into large sums over time.
Step 4: Set AUM and Liquidity Minimums
Filter for ETFs with at least $100 million in assets under management. This threshold accomplishes two things: it ensures reasonable liquidity (tighter bid-ask spreads) and it reduces the risk of your fund being shut down due to insufficient assets.
For additional safety, you can also filter for minimum daily trading volume — 100,000 shares per day is a good floor. But AUM is the more important metric since an ETF's true liquidity comes from its underlying holdings, not just its own trading volume.
Step 5: Sort by Performance or Yield
Once you've applied your filters, sort the remaining funds by the metric most relevant to your goal. For growth-oriented investments, sort by one-year or three-year returns to see which funds are performing best. For income, sort by dividend yield.
Remember that past performance doesn't guarantee future results, especially over short periods. A fund that topped the charts last year might lag next year. Use performance as one data point, not the sole decision factor. For index funds tracking the same benchmark, performance should be nearly identical — sort by expense ratio instead.
Step 6: Compare Your Shortlist
Your screening should produce three to five candidate ETFs. Now it's time for a deeper comparison using the ETF Beacon comparison tool.
Look at the metrics that screeners don't always show: holdings overlap with your existing portfolio, tracking error versus the benchmark, and tax efficiency for taxable accounts. Our guide to comparing ETFs walks you through this process in detail.
Common Screening Mistakes to Avoid
Over-filtering: Using too many criteria can eliminate perfectly good funds. Three to five filters are enough. Don't add a filter unless it meaningfully narrows the list toward your goal.
Chasing performance: Sorting by one-year return and picking the top result is a recipe for disappointment. Last year's winners are often this year's laggards, especially in niche categories.
Ignoring AUM: That micro-cap frontier market ETF with a 0.03% expense ratio and amazing returns might have $10 million in assets and spreads wide enough to drive a truck through. Size matters for practical trading.
Screening once and forgetting: The ETF market is dynamic. New funds launch, fees get cut, and old funds close. Revisit your screening at least once a year to make sure your funds are still the best option in their category.
Putting It Together: A Sample Screening Session
Let's say you want a US large-cap ETF for your core portfolio. Here's how the process works:
Filter 1: Category = US Large Cap. This narrows to about 100 ETFs.
Filter 2: Expense ratio under 0.10%. Down to about 30 funds.
Filter 3: AUM over $1 billion. Down to about 15 funds.
Sort by: Expense ratio, lowest first. Your top results will be familiar names — VOO, IVV, SPLG, VV, SCHX.
From here, pick two or three to compare in depth. Check their holdings, tracking error, and how they fit with your existing portfolio. Within 15 minutes, you'll have your answer. If the S&P 500 is your target, see our guide to choosing an S&P 500 ETF for the final decision.
