The Data Behind How To Screen ETFs: What Statistics Show
Written by Renan Filho, Technology & AI specialist. Expiry dates and activation fees are always visible.
Quick Answer: Statistics show that screening ETFs requires more than looking at past returns. Data on liquidity, expense ratios, and tracking error separates winners from traps. Here is what the numbers tell US traders.
Key Facts for US Traders (2026)
| Market | Detail | Source |
|---|---|---|
| US indices | S&P 500, NASDAQ, Dow Jones | NYSE / NASDAQ |
| Regulator | CFTC (futures) / SEC (securities) | Official |
| Prop firm model | Funded evaluations with profit split 70-95% | Vendor terms |

Volume and liquidity: the first filter
Ignore ETFs with average daily volume below 500,000 shares. Low volume means wider spreads and slippage. A $50,000 trade on a thin ETF can cost you $200 in spread. Stick to ETFs with at least $100 million in AUM. That data is free on any decent screener.
Expense ratios: why 0.20% matters
The difference between a 0.03% and 0.30% expense ratio is $270 per year on a $100,000 position. Over ten years, that's $2,700 lost to fees. I only consider ETFs under 0.20% unless the sector exposure is unique. Cheaper is almost always better.
Tracking error: the hidden cost
Tracking error measures how far an ETF deviates from its index. A tracking error above 0.50% per year means the fund is doing a bad job. For S&P 500 ETFs, I want under 0.10%. Don't trust the expense ratio alone – check the actual tracking difference on the issuer's site.
Sector exposure and correlation
Many ETFs overlap. QQQ and VGT have 60% overlap in tech stocks. Use correlation data to avoid building a concentrated portfolio. A good screener shows top holdings and sector weights. If two ETFs have a correlation above 0.90, pick only one.
Dividend yield and total return stats
Yield chasing is dangerous. A 4% yield may come from a shrinking dividend base. Look at payout ratios and dividend growth over five years. Total return over 3-5 years matters more than yield alone. Screen for consistent total return above the category average.
Quick Comparison
| Metric | Good Range | Why It Matters |
|---|---|---|
| Avg Daily Volume | >500,000 shares | Tighter spreads, easier execution |
| Expense Ratio | <0.20% | Lower cost compounds over time |
| AUM | >$100M | Less risk of closure, better liquidity |
| Tracking Error | <0.30% annually | Keeps performance close to index |
| 1-Year Total Return | Top quartile of category | Shows recent momentum and efficiency |

What is the best free ETF screener?
Finviz and ETFdb offer solid free screeners. Pay for more data if you trade frequently.
Should I use a screener that shows only US-listed ETFs?
Yes, if you trade on NYSE or Nasdaq. Stick to US-listed to avoid currency risk and lower liquidity.
How do I screen for low expense ratio ETFs?
Set a filter for expense ratio below 0.10%. Most major issuers like Vanguard and iShares have cheap options.
What is a good AUM for an ETF?
Above $100 million is safe. Below $50 million, the fund may close or have wide spreads.
