Understanding ETF performance data is essential for making informed investment decisions. Unfortunately, performance numbers can be misleading if you do not know what you are looking at. This guide explains every metric you will encounter and how to use them to evaluate any ETF.
Price Return vs. Total Return
This is the most important distinction in ETF performance. Price return measures only the change in the ETF's share price. Total return includes price changes plus all reinvested dividends and capital gains distributions. For a dividend-paying ETF like SCHD, total return can be 2-4% higher per year than price return.
Always use total return when comparing ETFs. A fund that pays higher dividends may appear to underperform on price return alone, even when it delivers superior total return. Most financial websites default to price return on their charts, so look for the total return toggle.
NAV Return vs. Market Price Return
ETFs have two types of returns: NAV (net asset value) return based on the value of underlying holdings, and market price return based on what shares actually traded for on the exchange. The difference reflects premiums and discounts. A well-functioning ETF will have nearly identical NAV and market returns over any meaningful period.
If you see a persistent gap between NAV and market returns, it may indicate liquidity issues or structural problems with the fund. This is most common in bond ETFs during periods of market stress and in international ETFs that trade while their underlying markets are closed.
Understanding Time Periods
Trailing returns (1-month, 3-month, 1-year, 3-year, 5-year, 10-year) show performance ending today. Calendar year returns show January-to-December performance for each year. Both are useful but tell different stories. A fund with excellent 5-year trailing returns might have had one spectacular year masking several mediocre ones.
Annualized vs. Cumulative Returns
A fund that returned 50% over 5 years has an annualized return of about 8.4%, not 10%. Annualized returns account for compounding and provide the fairest comparison across different time periods. Cumulative returns are useful for understanding your actual wealth growth.
Benchmark Comparison
An ETF should always be evaluated against its stated benchmark. A technology ETF that returned 15% sounds great until you learn its benchmark returned 18%. Conversely, a bond ETF that returned 3% is excellent if bonds broadly returned 1%. Check the fund's prospectus for its official benchmark, and look for tracking difference data.
Risk-Adjusted Returns
Two ETFs with identical returns are not equal if one was twice as volatile. Sharpe ratio measures return per unit of risk — higher is better. Sortino ratio is similar but only penalizes downside volatility. Maximum drawdown shows the worst peak-to-trough decline, which tells you how painful the ride was.
Putting It All Together
When evaluating an ETF, look at total return over multiple time periods, compare against the proper benchmark, consider risk-adjusted metrics, and check that NAV and market returns are closely aligned. No single number tells the full story. Visit our education center for more guides on ETF analysis and selection.
