Biggest Regime Stress Change

As of April 21, 2026 (end-of-day snapshot). Pages update daily after the market close.

Day-over-day delta in regime stress score — catching fresh regime transitions as the market re-prices. Positive deltas signal stress loading (moving toward STRESS/CRISIS); negative deltas signal stress relief. Pairs naturally with model divergence for a complete regime-transition stack.

Frequently Asked Questions

How quickly do scores change?

Day-over-day changes above 0.3 are meaningful; above 0.8 are unusual and typically correspond to regime-level news (earnings, FOMC, macro prints).

Is a negative delta bullish?

Not directly. Stress decreasing accompanies vol mean-reversion, which is not the same as price moving up. Directional signal comes from elsewhere.

Why might a CRISIS symbol show zero delta?

The delta captures incremental change, not absolute level. A persistent CRISIS regime shows zero delta while still being meaningful — use the level screener for absolute and this for transitions.

How does this relate to biggest-iv-change?

IV change is a single-feature signal. Regime stress change is multi-feature — incorporating term structure, skew, tail dominance, and model disagreement alongside IV level. When they agree, the shift is unambiguous; when they disagree, a non-IV feature is driving.
