1. Full Factor IC Test (21-day holding)
| Factor | IC Mean | ICIR | p-value | L/S Return | Signal |
|---|---|---|---|---|---|
| EP | -0.0624 | -0.742 ⭐ | 0.00005 ⭐ | +3.87% | Effective |
| BP | +0.0056 | +0.078 | 0.635 | +0.82% | Not significant |
| FCF Yield | -0.0589 | -1.426 ⭐ | <0.0001 ⭐ | +3.04% | Effective |
| ROE | -0.0414 | -1.230 ⭐ | <0.0001 ⭐ | +1.11% | Effective |
| Mom | +0.2241 | +2.697 ⭐ | <0.0001 ⭐ | -8.07% ⭐ | Strong/Monotonic |
| Vol | +0.1320 | +1.051 ⭐ | <0.0001 ⭐ | -7.61% | Effective |
| Size | +0.0479 | +1.250 ⭐ | <0.0001 ⭐ | -2.06% | Effective |
Key Findings:
- Momentum ICIR=2.70 is the strongest predictive factor, but L/S return of -8.07% with monotonic排列 signals a momentum reversal — classic crowding-induced mean reversion setup.
- Volatility factor aligns with momentum (low-vol outperforms), ICIR=1.05, L/S -7.61%.
- Value cluster (EP, FCF Yield, ROE) shows negative IC with positive L/S — low-valuation stocks outperforming. Defensive signal.
- BP the only insignificant factor, p=0.635.

2. Momentum by Sector
| Sector | IC Mean | ICIR | L/S Return | Signal |
|---|---|---|---|---|
| Information Technology | +0.524 | +2.584 ⭐ | -28.54% ⭐ | Extreme/Monotonic |
| Industrials | +0.266 | +2.878 ⭐ | -7.14% ⭐ | Strong/Monotonic |
| Financials | +0.309 | +2.626 ⭐ | -7.19% | Strong |
| Consumer Discretionary | +0.252 | +2.110 ⭐ | -6.21% ⭐ | Effective/Monotonic |
| Consumer Staples | +0.209 | +1.341 ⭐ | -4.67% | Effective |
| Utilities | +0.199 | +1.007 ⭐ | -0.63% | Marginal |
| Real Estate | +0.124 | +0.840 ⭐ | -3.83% | Marginal |
| Health Care | -0.128 | -1.206 ⭐ | +7.51% | Contrarian |
Sector Signals:
- IT sector momentum at extremes: IC=+0.524 (highest), L/S -28.54% — a handful of mega-cap tech stocks absorbing all market attention with severe internal dispersion.
- Health Care contrarian: Negative IC with +7.51% L/S — low momentum outperforms, pure defensive play.
- Systematic crowding: All sectors (except healthcare) show “momentum wins” pattern — the uniformity itself is a warning.
3. Anomaly Detection
✅ All factors within normal range. No anomalies flagged.
4. Strategy Implications
- Momentum in danger zone: Higher ICIR + more extreme L/S returns = closer to reversal. IT’s -28.54% L/S is historically extreme.
- Value gaining traction: EP, FCF Yield, ROE all effective — overweight low-valuation defense.
- Healthcare is the only sector with reverse momentum — natural hedge.
- Watch for crowding: When every sector shows monotonic “momentum wins,” the crowded trade is likely at its peak.
