Factor IC Test Overview
| Factor | IC Mean | ICIR | p-value | Q1 Return | Q5 Return | Long-Short | Verdict |
|---|---|---|---|---|---|---|---|
| EP | -0.062 | -0.74 | 0.00005 | +6.41% | +2.54% | +3.87% | π‘ Reverse effective |
| BP | +0.006 | +0.08 | 0.635 | +3.88% | +3.06% | +0.82% | βͺ Ineffective |
| FCF Yield | -0.059 | -1.43 | β0 | +5.64% | +2.60% | +3.04% | π΄ Significantly reversed |
| ROE | -0.041 | -1.23 | β0 | +4.82% | +3.71% | +1.11% | π΄ Significantly reversed |
| Momentum | +0.224 | +2.70 | β0 | -0.12% | +7.95% | -8.07% | π’ Strong momentum |
| Volatility | +0.132 | +1.05 | β0 | +0.54% | +8.15% | -7.61% | π’ High vol outperforms |
| Size | +0.048 | +1.25 | β0 | +2.45% | +4.51% | -2.06% | π’ Large underperforms |
Key Takeaways:
- Momentum reigns supreme: IC=+0.224, ICIR=2.70, 100% positive IC ratio β textbook momentum signal. Q5 (strongest) returns +7.95% vs Q1 (weakest) -0.12%. Long-short spread -8.07%.
- Value trap deepens: EP significantly reversed (IC<0), low PE stocks outperforming. Market ignoring cheapness, chasing growth stories. BP completely useless β book value has zero pricing power.
- Risk-on appetite: High volatility stocks dramatically outperform (Q5 +8.15%). Leveraged/risk-on positioning intact.
- Large caps lag: Size factor positive but mild β market activity skewing toward mid/small names.

Sector Read:
- Tech dominance: IT sector IC=+0.524, Q5 +27.19% in a single week β not normal momentum premium, but extremely concentrated crowding. AI chip/software names driving narrow market advance.
- Financials/Industrials steady: ICIR 2.6-2.8, high consistency. Market positioning for late-cycle economic scenarios.
- Health Care reversal: Only sector with negative IC. Q1 (most beaten-down) rebounding hardest (+4.84%) β classic mean-reversion. Capital rotating from high-valuation to defensive names.
- Utilities/Staples tepid: Defensive sectors showing weak momentum β not yet in true risk-off mode.
Summary & Strategy Implications
Market State: Extreme momentum concentration + breadth deterioration. 5 of 7 factors significantly effective, but all pointing the same direction: long high momentum/vol/mid-small, short value/low-vol. Classic late-cycle signature.
Risk Flags:
- IT sector Q5 +27% momentum premium unsustainable β reversal will trigger cascade
- Breadth narrowing (extreme fear), few mega-caps masking underlying weakness
- Value factors comprehensively failed (EP reversed, BP useless) β historically precedes significant pullbacks
Strategy Suggestions:
- Short-term momentum positions maintainable with strict trailing stops (-5% recommended)
- Watch healthcare for reversal opportunities (oversold + rotation flow)
- Do not chase new IT positions at current levels
- Maintain elevated cash allocation, await breadth signal improvement
