Factor IC Test
| Factor | IC Mean | ICIR | Long-Short Ret | IC+ % | p-value | Signal |
|---|---|---|---|---|---|---|
| Momentum (mom) | 0.224 | 2.70 | -8.07% | 100.0% | 0.0000 | π’ Excellent |
| Volatility (vol) | 0.132 | 1.05 | -7.61% | 79.5% | 0.0000 | π’ Effective |
| Size | 0.048 | 1.25 | -2.06% | 87.2% | 0.0000 | π’ Effective |
| FCF Yield | -0.059 | -1.43 | +3.04% | 7.7% | 0.0000 | π΄ Reversal |
| ROE | -0.041 | -1.23 | +1.11% | 12.8% | 0.0000 | π΄ Reversal |
| EP | -0.062 | -0.74 | +3.87% | 17.9% | 0.0001 | π΄ Reversal |
| BP | 0.006 | 0.08 | +0.82% | 46.2% | 0.6355 | βͺ Ineffective |
Key Findings:
- Momentum ICIR 2.70 with 100% IC positive rate β the only consistently effective factor over the past 39 rebalancing periods.
- Volatility factor ICIR 1.05 β high-vol stocks outperform, highly correlated with momentum (growth/tech stocks exhibit both).
- Size factor ICIR 1.25 β small-cap premium stable, but long-short return only -2.06%, indicating tail risk.
- All value factorsε€±ζ: EP, FCF Yield, ROE ICs are all negative β high-valuation/quality stocks underperform. Classic growth-dominated regime.
- BP factor completely ineffective β IC near zero, statistically insignificant.

Sector Momentum Decomposition
| Sector | ICIR | Q5 Return | Long-Short | Trend |
|---|---|---|---|---|
| Information Technology | 2.58 | 27.19% | -28.54% | π₯ Extremely strong |
| Industrials | 2.88 | 5.51% | -7.14% | π’ Strong |
| Financials | 2.63 | 7.80% | -7.19% | π’ Strong |
| Consumer Discretionary | 2.11 | 2.15% | -6.21% | π’ Effective |
| Consumer Staples | 1.34 | 0.02% | -4.67% | π‘ Moderate |
| Utilities | 1.01 | -1.66% | -0.63% | βͺ Weak |
| Real Estate | 0.84 | 4.95% | -3.83% | βͺ Weak |
| Health Care | -1.21 | -2.66% | +7.51% | π΄ Reversal |
Key Findings:
- Information Technology momentum ICIR 2.58, Q5 return 27.19% β tech momentumι₯ι₯ι’ε with near-perfect monotonic Q1βQ5 progression.
- Health Care is the only reversal sector: ICIR -1.21, low-momentum stocks outperform high-momentum. Signals possible sector rotation as capital flows from high-valuation to low-valuation names.
- Industrials and Financials show stable momentum effects (ICIR > 2.6) with strong Q5 returns.
- Utilities and Real Estate momentum weak, ICIR below 1.05.

Strategy Implications
- Long: Continue overweighting high-momentum + high-volatility combos, especially in IT/Industrials/Financials. Momentum’s 100% IC positive rate is the most reliable alpha source available.
- Hedging: Watch Health Care reversal signal β if it spreads to other sectors, may signal momentum factor crowding at peak.
- Value Trap: EP/ROE/FCF Yield allε€±ζ β the market’s pricing logic for “cheap quality” hasζθ£. Don’t try to bottom-fish “value.”
- Small-Cap Premium: Size ICIR 1.25 but long-short only -2.06% β high dispersion within small caps means stock selection is critical.
