Sectoral Employment Diffusion Signal

Signal Summary:

• Configuration statement: Given a Diffusion Index of 25.0 and a negative three-month momentum of -25.0, this setup aligns with Downward-biased price paths and Elevated volatility, where the dominant risk is Regime shift, not trend continuation. (1)
• The signal has entered a "COOL (narrow/weak)" regime as of December 2025, reflecting a significant contraction in hiring breadth. (1)
• Conviction Band: Low; Interpretation Confidence: Low Confidence; Internal Conflict Flag: Yes. Signal Stability Assessment: Volatile; Threshold Proximity: Near; Revision Sensitivity: High.

Methodology Applied:

• A Diffusion z-score below -0.75 (currently -2.5e10) triggers the COOL regime, signifying narrowing hiring breadth and weakening labor participation. (1)
• Negative 3-month momentum in the Diffusion Index serves as a warning of potential transition to a weaker economic stage. (1)
• Sectoral Employment Diffusion Signal, latest observation: 2025-12-01. (1)

Key Dynamics:

• The primary driver is the collapse of the Diffusion Index to 25.0, indicating that only a minority of tracked sectors are seeing positive payroll growth. (1)
• Negative momentum (-25.0) confirms a rapid deceleration in labor market participation. (1)
• Internal Conflict: The extreme magnitude of the latest z-score relative to the index move suggests potential data instability or calculation noise.
• Conditional Invalidation: A return of the Diffusion Index above 50.0 and a z-score move above -0.75. (1)

Scenario Balance:

• Base case dominant: Continued labor market softening as hiring freezes spread across sectors.
• Upside risk: Stabilization in service-sector demand leads to a reversion to Neutral.
• Downside risk: Broadening sector losses trigger a formal cyclical contraction.

Time Horizon & Aggregation:

• Time Horizon: Cyclical (months), as employment breadth typically leads broader economic shifts. (1)
• Aggregation Weight Hint: Low, due to the extreme z-score volatility and recent regime flip-flopping.

Macro Relevance:

• This signal informs the "Labor Market" dimension of the macro cycle. (1)
• Economic mechanism: Narrowing hiring breadth implies a loss of demand impulse and rising downside risks to growth. (1)
• Cycle position: Not determined; however, the methodology notes that low diffusion signals rising risk-off sentiment. (1)

Regime Context:

• The signal is in a state of deterioration, having failed to sustain its November recovery and re-entering the COOL regime. (1)
• Direction of change: Weakening.

Model Limitations:

• Lagging nature of employment data and high sensitivity to BLS revisions. (1)
