Style decomposition

R² 41% · 668 weekly obs

Multivariate regression of weekly mirror excess return on five style factors built from the benchmark ETFs: SPY (market), IWM−SPY (size), QQQ−SPY (growth), EFA−SPY (international), AGG−SPY (bonds). The intercept is the “true alpha” after stripping these passive tilts. ✓ marks loadings whose |t-stat| ≥ 2 (≈ 95% confidence the loading is non-zero).

Whether the headline alpha was earned recently or decades ago. Bands above the zero line are quarters where the mirror beat QQQ on a trailing-year basis; bands below are quarters where it lost ground. A flat positive line = steady outperformance; a curve that crosses often = regime-dependent strategy.
