Market Structure Score
49/100
Weak Structure
🔁 Regime shift: Broad Bull → Neutral
Internal activity reflected active sector rotation rather than a decisive directional trend, with capital continuing to migrate between market leadership groups. Internal confirmation remains limited, reducing confidence in the durability of the current market character.
Underlying market conditions have weakened sufficiently to raise questions about the durability of the current trend. The Market Structure Score of 49/100 reflects low confidence in this assessment.
⬥ 272 of 502 stocks advanced (▲54.2%)
⬥ 224 stocks declined (▼44.6%)
⬥ 6 stocks unchanged
⬥ Leadership continued to rotate.
⬥ Leadership was broadly distributed.
Leadership continued to rotate across sectors, but weakening participation and internal confirmation suggest the rotation is becoming less supportive of the broader market trend.
Rapid leadership rotation suggests institutional conviction remains fluid. Breadth continues to lag headline index performance. Participation has weakened across the broader market. Trading conviction remains below recent norms. Should these conditions deteriorate further, confidence in the current market assessment would likely weaken.
The outlook remains cautious until participation broadens, leadership stabilizes, and internal confirmation begins to recover.
The weight of the internal evidence continues to support an orderly sector rotation market environment with low confidence. While short-term price fluctuations are inevitable, sustained improvement in participation and leadership would reinforce the current assessment, whereas renewed deterioration in market internals would warrant a more defensive interpretation.

Definitions:
Contribution – The weighted impact of a stock’s return on the overall index move
(weight × return). This reflects how much each stock actually moved the index.
Share – The proportion of total index movement attributable to a given stock.
Higher values indicate outsized influence relative to peers.
Impact Efficiency – The ratio of contribution to return, highlighting how effectively
a stock’s price move translates into index impact (primarily driven by index weight).
