Evaluating ETF performance seems straightforward — just check the returns, right? In practice, meaningful evaluation requires looking at the right metrics, over the right time periods, against the right benchmarks. Many investors draw wrong conclusions by skipping these steps.
Start with Total Return
Always evaluate total return, which includes price appreciation plus reinvested dividends and distributions. Price return alone understates the performance of dividend-paying ETFs. A fund like SCHD with a 3%+ yield would appear to underperform growth ETFs on price return alone, even when total return is competitive or superior.
Most financial websites default to price return on their charts. Look for a "total return" toggle or use the fund issuer's performance page, which typically reports total return as the standard.
Choose the Right Benchmark
An S&P 500 ETF should be measured against the S&P 500 index. A small-cap value ETF should be measured against a small-cap value index. Comparing a bond ETF's return to the stock market's return tells you nothing useful about the bond ETF's quality. Always identify the fund's stated benchmark from the prospectus.
Tracking Difference for Index Funds
For index ETFs, the gap between the ETF's total return and its benchmark return (tracking difference) is the truest measure of fund quality. A fund that consistently matches its benchmark minus expenses is doing its job well. A fund with erratic or excessive tracking gaps has operational problems.
Multiple Time Periods
Evaluate 1-year, 3-year, 5-year, and 10-year returns to get a complete picture. A fund with stellar 1-year returns might have been terrible for the previous four years. Calendar year returns (showing each January-to-December result) reveal consistency and show how the fund performs in different market environments.
Risk-Adjusted Metrics
Sharpe ratio divides excess return (return above the risk-free rate) by volatility. Higher is better. A fund returning 10% with 15% volatility has a better Sharpe ratio than one returning 12% with 25% volatility. Maximum drawdown shows the worst peak-to-trough decline — important for understanding what pain you might endure.
Putting It Together
The ideal ETF delivers total returns that closely track its benchmark (for index funds) or consistently outperform after fees (for active funds), with acceptable risk-adjusted metrics and reasonable maximum drawdown.
