ETF comparison
Verified factor-similar pair
OUSA vs QDEF
These US-listed equity ETFs share verified FF6 US factor exposure. The modeled volatility of their factor-return difference is at or below 3% annualized on both the same 36-month window and a longer factor-history check.
CMA
Current similarity score
85
Factor-similar
The score is 100 for identical fitted exposures and 80 at the 3% modeled tracking-error limit. It includes market and non-market factors; it does not indicate which fund earned or is expected to earn more. How to read this score.
Quick Read
- QDEF has the higher backtested relative Sharpe (1.305 vs 0.954).
- QDEF has the lower published fee (0.40% vs 0.48%).
- OUSA is cheaper on dividend valuation (143 vs 158, where 100 is each fund's historical median).
- QDEF has the stronger regression fit (adjusted R-squared 0.945 vs 0.893).
These are screening signals, not a complete review of portfolio construction, turnover, taxes, or trading quality.

Market beta uses the common 36-month window through 2026-08. Adjusted R² and relative Sharpe describe each fund's separately published full-history model.
Factor Exposure Match
Blue bars compare factor beta magnitude from the same 36 months shown above. Green bars compare absolute t-stat strength; dim bars indicate |t| below 1.96. Every factor enters the distance calculation regardless of its t-statistic.

What Happened Over the Same 36 Months
OUSA adjusted total-return CAGR
13.63%
QDEF adjusted total-return CAGR
18.93%
QDEF ahead by 5.30 percentage points/year over 2023-09 through 2026-08. This is the observed difference between annualized compounded returns from adjusted prices, not an expected return or a factor-model estimate.
Historical factor attribution
Signed contribution to OUSA minus QDEF, percentage points/year, using fitted 36-month exposures and average factor returns over those same months:
Market factor
-0.12
Other factors, combined
-0.27
Total factor-implied difference
-0.39
This arithmetic-average factor attribution excludes the regression intercept and fund-specific return. It therefore need not equal the observed CAGR difference and is not a forecast.

Fitted exposures and factor covariance estimate the volatility, not the average or direction, of the funds' modeled return difference. The common regression window is 2023-09 through 2026-08. A short-window estimate and a longer factor-history check must both be at or below 3.000%; this is a screening limit, not a forecast. Holdings, turnover, taxes and trading costs require a separate review. The Sharpe figures elsewhere on this page come from each fund's published full-history model and do not enter similarity ranking. See the full methodology.
