Positive IC = factor value positively correlated with future returns. Long-Short = Q1−Q5; negative means high-factor group outperforms.

Key Findings

Momentum dominance persists. Momentum ICIR 2.70, 100% positive hit rate over 39 rolling periods, long-short spread −8.07%. High-momentum Q5 averaged +7.95% vs Q1 at −0.12%. Momentum has not failed in a single rolling month.

Value factors fully inverted. EP (IC −0.062), FCF Yield (IC −0.059), and ROE (IC −0.041) all show significantly negative ICs. Cheap/high-quality stocks continue to underperform — a hallmark of momentum-driven markets where capital chases trends over fundamentals.

Low-vol anomaly reversed. Volatility IC +0.132 — high-vol stocks outperforming low-vol by +7.61%. The exact opposite of the traditional low-vol premium, signaling a return of risk appetite.

Large-cap preference established. Size IC +0.048, t-stat 7.7, 87.2% positive rate. Large caps consistently outperforming small caps, consistent with liquidity-concentrated markets.

BP factor neutral. Book-to-price IC near zero, not statistically significant. The only fundamental factor without a clear directional signal.

Sector Highlights

Tech in a league of its own. Info Tech IC 0.524, Q5 averaged +27.19%, long-short spread −28.54%. Momentum in tech is crushing — high-momentum tech stocks gained 27% on average over the period.

Health Care is the sole contrarian sector. IC −0.128 means low-momentum healthcare stocks outperform high-momentum ones. Classic mean-reversion signal — previously overextended healthcare names correcting while laggards rebound. Q1 (low momentum) +4.84%, Q5 (high momentum) −2.66%.

Financials and Industrials show robust momentum. Both with ICs in the 0.27–0.31 range, 100% positive hit rates, long-short spreads around −7%. Financials’ ICIR of 2.63 even edges out Tech in stability.

Utilities and Real Estate momentum weaker. ICs below 0.20, ICIRs under 1.0 — statistically significant but directionally weaker.

Sector Momentum

Overall Assessment

The market is in a classic momentum-driven, value-failing regime. Only momentum, volatility, and size show significant positive ICs among seven factors; three value/quality factors are significantly inverted. This structure typically appears in:

  • Mid-to-late stage trending markets (momentum self-reinforcement)
  • Abundant liquidity environments (capital chasing growth and trends)
  • Fundamental factors temporarily suppressed by sentiment

At the sector level, Tech momentum is extreme (IC 0.524), while Health Care is the lone reversal signal — suggesting Tech may be approaching late-stage acceleration and Health Care is undergoing sector rotation.

⚠️ Risk note: 100% momentum hit rate is unsustainable. When it begins to crack, it often signals the start of a style rotation.
