Key Findings
- Momentum continues to dominate: IC mean 0.224, ICIR 2.70, 100% positive IC across all 39 observations. Q5 portfolio monthly return +7.95%, Q1 at -0.12%, long-short spread -8.07% (short-side advantage).
- Value/quality reversal in full force: EP, FCF Yield, and ROE all show negative IC, indicating “low valuation + high profitability” underperforming. FCF Yield has the strongest absolute ICIR (1.43).
- Volatility premium: vol factor IC 0.132, ICIR 1.05. High-vol stocks outperforming significantly, Q5 +8.15% monthly.
- Large-cap tilt: size factor slightly positive, modest large-cap advantage (ICIR 1.25).

Sector Analysis
- Tech momentum accelerating: IT sector IC at 0.524 is more than double the market-wide figure. Q5 +27.19% monthly vs Q1 -1.35% — extreme dispersion, classic trending market.
- Financials/Industrials following: Both with ICIR > 2.6, stable but less intense than tech.
- Health Care contrarian: Only sector with negative IC — low-momentum stocks outperforming high-momentum by a wide margin (Q1 +4.84% vs Q5 -2.66%). Potential early signal of rotation into defensives.
Anomaly Detection
No anomalies triggered. All factor ICs within historical normal ranges.
Strategy Implications
- Trend following remains effective: Momentum factor IC 2.70 + 100% positive rate — long strong / short weak continues to work.
- Watch for crowding: When momentum IC exceeds 0.2 with ICIR > 2.5, markets often approach late-stage single-direction moves. Monitor reversal risk.
- Tech concentration risk: IT Q5 +27% monthly is an extreme reading — trend reversals could produce violent drawdowns.
- Health Care as potential rotation signal: Strongest momentum reversal in the sector, may be a leading indicator of style rotation.
