Key Findings:
- Momentum factor dominant: ICIR +2.70, IC mean +0.224, with monotonic L/S return -8.07% — trend following remains effective
- Value factors reversing: EP (ICIR -0.74), FCF (ICIR -1.43), ROE (ICIR -1.23) all show negative IC with positive L/S returns — market penalizing high valuations, rewarding low valuations
- bp factor ineffective: p-value 0.635, statistically insignificant

- Tech momentum overwhelming: IC mean +0.524, ICIR +2.58, monotonic L/S -28.54% — extremely strong trend
- Healthcare reversal signal: Negative IC (-0.128) with positive L/S — defensive sector seeing capital inflow
- Industrials steady trend: Highest ICIR at +2.88, but non-monotonic L/S — monitor sustainability
Anomaly Detection
✅ All factors within normal fluctuation range, no anomaly signals.
Summary
Market is in a trend-driven phase: momentum factor remains effective while value factors show universal reversal. Tech sector momentum is extreme (ICIR +2.58), but watch for crowding risk. Healthcare shows defensive reversal signals — potential early sign of style rotation. bp factor is statistically dead (p=0.635).
