Factor IC Analysis
| Factor | IC Mean | ICIR | t-stat | IC>0% | Long-Short | Verdict |
|---|---|---|---|---|---|---|
| Momentum (mom) | +0.224 | 2.70 | 16.6 | 100% | -8.07% | ⭐ Dominant |
| Volatility (vol) | +0.132 | 1.05 | 6.5 | 80% | -7.61% | ✅ Strong |
| Size | +0.048 | 1.25 | 7.7 | 87% | -2.06% | ✅ Strong |
| EP | -0.062 | -0.74 | -4.6 | 18% | +3.87% | ⚠️ Inverse |
| FCF Yield | -0.059 | -1.43 | -8.8 | 8% | +3.04% | ⚠️ Inverse |
| ROE | -0.041 | -1.23 | -7.6 | 13% | +1.11% | ⚠️ Inverse |
| BP | +0.006 | 0.08 | 0.5 | 46% | +0.82% | ❌ No signal |
Key Takeaways:
- Momentum reigns supreme: IC=0.224, ICIR=2.70, 100% positive IC — the undisputed alpha king
- Value factors collectively failing: EP/FCF/BP all negative or insignificant — market refuses to reward “cheap”
- Volatility factor: Highly collinear with momentum, essentially expressing the same signal

Sector Momentum Decomposition (IC by Sector)
| Sector | IC Mean | ICIR | IC>0% | Q5 Return | Long-Short | Signal |
|---|---|---|---|---|---|---|
| IT | +0.524 | 2.58 | 100% | +27.2% | -28.5% | 🔥 Extreme momentum |
| Financials | +0.309 | 2.63 | 100% | +7.8% | -7.2% | 🔥 Strong momentum |
| Industrials | +0.266 | 2.88 | 100% | +5.5% | -7.1% | 🔥 Strong momentum |
| Consumer Disc. | +0.252 | 2.11 | 100% | +2.2% | -6.2% | ✅ Moderate-strong |
| Consumer Staples | +0.209 | 1.34 | 87% | +0.0% | -4.7% | ✅ Moderate |
| Utilities | +0.199 | 1.01 | 77% | -1.7% | -0.6% | ⚠️ Weak |
| Real Estate | +0.124 | 0.84 | 74% | +4.9% | -3.8% | ⚠️ Weak |
| Health Care | -0.128 | -1.21 | 15% | -2.7% | +7.5% | ⬇️ Inverse momentum |
Key Findings:
- IT sector momentum is extreme: IC=0.52, Q5 (strongest) annualized +27.2%, Q1 (weakest) -1.4% — a 30pp gap — classic momentum crowding signal
- Healthcare shows inverse momentum: IC=-0.128, weaker names outperforming, suggesting rotation from growth to defense
- Financials/Industrials strong: Cyclical sectors maintaining momentum, but watch rate trajectory

Risk Alerts
- Momentum crowding at extremes: 100% positive IC + IT Q5/Q1 gap of 30pp — historically this precedes momentum crashes
- Value factors going inverse: Market paying premium for growth, discounting value — common in late-cycle environments
- Watch for reversal signals: Any sudden shift from high-beta to low-beta would trigger violent momentum factor drawdowns
