ETF Reference Tables

ETF reference tables cover the quantitative benchmarks investors use when selecting and comparing funds. Which expense ratio is considered low for a given category? How much tracking error is normal for a bond ETF versus an equity ETF? How have fund flows shifted between asset categories over time? These tables provide the reference data that makes those comparisons concrete.

Direct Answer

ETF reference tables provide the benchmarks needed to evaluate whether a fund's costs, tracking accuracy, and liquidity are competitive within its category. An expense ratio of 0.20% might be reasonable for an actively managed fund but expensive for a large-cap index ETF where the category average is below 0.10%. Reference data makes those distinctions apparent.

Common questions

What is a reasonable expense ratio for different ETF categories?

Expense ratios vary significantly by asset class and management style. Broad US equity index ETFs from major providers now charge 0.03% to 0.05%. International equity ETFs typically range from 0.05% to 0.20%. Bond ETFs range from 0.03% for broad aggregate funds to 0.40% or more for high-yield or active funds. Thematic and factor ETFs generally charge more than plain index funds. Comparing a fund's expense ratio to the category average is a better benchmark than any single absolute threshold.

What causes tracking error in an ETF?

Tracking error is the difference between an ETF's return and its benchmark index return. The main sources are the expense ratio (the most consistent driver), dividend reinvestment timing (ETFs cannot immediately reinvest dividends the way the index assumes), securities lending income (which can partially offset expenses), and sampling decisions for ETFs that do not hold every index constituent. A small amount of tracking error is expected; persistent large deviations indicate execution problems.
