Verified factor-similar pair

PSCI vs SLYG

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.

SMB
Current similarity score
80
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

  • PSCI has the higher backtested relative Sharpe (1.188 vs 0.621).
  • SLYG has the lower published fee (0.15% vs 0.29%).
  • PSCI is cheaper on dividend valuation (51 vs 120, where 100 is each fund's historical median).
  • SLYG has the stronger regression fit (adjusted R-squared 0.925 vs 0.908).

These are screening signals, not a complete review of portfolio construction, turnover, taxes, or trading quality.

What Happened Over the Same 36 Months

PSCI adjusted total-return CAGR
19.41%
SLYG adjusted total-return CAGR
14.41%

PSCI ahead by 4.99 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 PSCI minus SLYG, percentage points/year, using fitted 36-month exposures and average factor returns over those same months:

Market factor
+2.01
Other factors, combined
-1.51
Total factor-implied difference
+0.50

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.
