Sector Momentum Decomposition
Key Findings
1. Momentum Factor Absolute Dominance
- ICIR 2.70, 100% positive IC rate, zero exceptions over 39 weeks
- “Stronger gets stronger” self-reinforcing loop still running
- But Q5 vs Q1 spread at 8% is at extreme levels — crowding risk is high
2. Value Factor “Dead Cat Bounce”
- EP and FCF ICs are negative (-0.06 and -0.06), yet Q1 (highest value) outperforms Q5
- Interpretation: value stocks declining less than growth stocks in an overall down market = “defensive value”
- This is NOT a value regime rotation — it’s mean reversion in overvalued growth dragging relative returns
3. Volatility Factor Directional Anomaly
- High-vol Q5 returns 8.15% vs low-vol Q1 at 0.54%
- Contradicts traditional low-volatility premium
- Market is “buying volatility” rather than “selling vol” — classic late-cycle risk-seeking
- This pattern reverses violently in drawdowns
4. Mild Small-Cap Premium
- Size ICIR 1.25, small-caps generating positive alpha
- But modest (-2.06% spread), suggesting liquidity conditions still manageable
- Watch for deterioration if FNG continues declining
Strategy Implications
- Momentum crowding extreme — any reversal could trigger outsized drawdown
- Value + Low Vol defense — relatively favored in current environment
- High-vol trading reversal risk — current “buy vol” positioning unwinds fast when VIX spikes
- Monitor small-cap liquidity — may be first to suffer if sentiment deteriorates further
