| BP | +0.0056 | +0.08 | 0.635 | +0.82% |
Key Signals
- Momentum dominates: ICIR 2.70 is the highest across all factors, with IC mean of 0.22. The -8.07% long-short return (long low-momentum, short high-momentum) shows perfect monotonic ranking.
- Quality factors reverse: EP, FCF Yield, ROE all show negative IC — high-valuation, low-cashflow stocks outperform. Classic late-cycle behavior.
- BP ineffective: Book/Price ratio IC near zero; traditional value factor completely broken.
Sector Momentum Decomposition
| Sector | IC Mean | ICIR | Long-Short | Verdict |
|---|---|---|---|---|
| Info Tech | +0.5240 | +2.58 ⭐ | -28.54% ⭐ Monotonic | 🔥 Extreme momentum |
| Industrials | +0.2659 | +2.88 ⭐ | -7.14% ⭐ Monotonic | Strong |
| Cons. Disc. | +0.2522 | +2.11 ⭐ | -6.21% ⭐ Monotonic | Strong |
| Financials | +0.3094 | +2.63 ⭐ | -7.19% | Strong |

Sector Takeaways
- Tech dominates: IC 0.52, ICIR 2.58, with -28.54% long-short showing perfect monotonic ordering. AI and semiconductor-driven momentum is extremely persistent.
- Industrials + Financials follow: Both sectors show IC >0.25 and ICIR >2.5, indicating solid momentum trends.
- Healthcare reverses: Negative IC means low-momentum healthcare stocks outperform — capital flows away from defensives.
- Defensive sectors weak: Utilities IC only 0.20 with near-zero long-short return; capital chases growth over safety.
Summary
- Momentum reigns supreme: Market is in a strong momentum continuation phase; trend-following remains effective.
- Quality factors broken: Valuation and profitability metrics are fully reversed — market ignores fundamentals, only follows trends.
- High sector concentration: Tech sector momentum IC is 2x other sectors; capital高度集中.
- Anomaly detection: All factors within normal range; no extreme anomalies detected.
- Risk warning: When momentum ICIR sustains >2.5 and quality factors are fully reversed, it often signals a market topping zone. Once momentum reverses, drawdowns can be severe.
