Market Structure Score
74/100
Healthy Structure
🔁 Regime shift: Narrow / Fragile → Broad Bull
Market internals strengthened as participation broadened beyond the largest capitalization stocks, reinforcing the durability of the prevailing advance. Most internal measures were broadly consistent with this assessment, although some divergence remains beneath the surface.
Most internal measures remain supportive of the prevailing trend, although enough divergence persists to justify a measured rather than aggressive level of conviction. The Market Structure Score of 74/100 reflects moderate confidence in this assessment.
⬥ 402 of 502 stocks advanced (▲80.1%)
⬥ 94 stocks declined (▼18.7%)
⬥ 6 stocks unchanged
⬥ Advancers clearly outnumbered Decliners.
⬥ Participation improved versus recent sessions.
Leadership continued to rotate across sectors, indicating investors were reallocating capital while maintaining overall risk exposure. The rotation remains constructive, although less robust participation warrants some caution.
Rapid leadership rotation suggests institutional conviction remains fluid. Breadth continues to lag headline index performance. Should these conditions deteriorate further, confidence in the current market assessment would likely weaken.
The market is approaching an important inflection point. Broader participation and firmer leadership would shift the balance toward a more constructive outlook, whereas weaker breadth would increase the probability of renewed internal deterioration.
The weight of the internal evidence continues to support a broad institutional accumulation market environment with moderate 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).
