No meaningful structural fragility is currently detected (Fragility Score 0/100, DTC percentile 93%) and liquidity softening modestly (volume -15%). Positioning is historically elevated, although price and liquidity conditions do not yet confirm structural fragility.

Risk Summary

No clear bull trap characteristics detected. Recent price behavior remains broadly consistent with current positioning.This reading helps confirm that current price action remains structurally healthy and does not indicate elevated trap risk.

Why Price Reactions May Be Stronger?

Days-to-Cover is elevated versus its own history, but absolute short interest remains moderate. Adaptive thresholds applied to liquidity weakness, near-high detection, and compression sensitivity. As a result, similar news or market events could lead to price moves about 1× larger than usual.


Note: Short interest data is reported every two weeks by FINRA. The most recent snapshot is 2026-07-31 (ET).
Because this data updates slowly, it is not intended to predict short-term price moves. Instead, it helps describe longer-term market structure and where pressure may be building if prices begin to move.
