Market Structure Score
52/100
Fragile Structure
🔁 Regime shift: Strong but Concentrated → Weak / Risk-Off
Selling pressure extended across a broad cross-section of the market, indicating widespread institutional distribution rather than isolated weakness. 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 52/100 reflects low confidence in this assessment.
⬥ 137 of 502 stocks advanced (▲27.3%)
⬥ 355 stocks declined (▼70.7%)
⬥ 10 stocks unchanged
⬥ Participation quality weakened.
⬥ Participation weakened versus recent sessions.
Leadership continued to rotate across sectors, indicating capital was being reallocated rather than concentrated in a single leadership group. However, weakening participation reduces confidence that the rotation represents a durable bullish signal.
Rapid leadership rotation suggests institutional conviction remains fluid. Participation has weakened across the broader market. Trading conviction remains below recent norms. Decliners continue to outnumber advancers. Should these conditions deteriorate further, confidence in the current market assessment would likely weaken.
Meaningful improvement in participation and internal confirmation will be needed before confidence can recover. Failure to improve would leave the market vulnerable to additional weakness.
The weight of the internal evidence continues to support a broad distribution 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.

(weight × return). This reflects how much each stock actually moved the index.

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).
