Index Strength Without Participation Is Fragile
Market breadth measures how many stocks are truly participating across daily, intermediate, and long-term horizons. Deterioration here often precedes regime and momentum breakdowns.

- •Multi-horizon participation, not single metrics
- •Momentum inflections and internal divergence
- •Deterministic, non-lookahead construction
Breadth reflects internal market health, not price direction.
