From levels to states
JW4 tracks direction, rate of change, persistence and percentile context. Low VIX with rising VVIX can signal fragile calm; elevated VIX with falling VVIX can indicate that stress remains high but is becoming more orderly.
Regime interactions
The framework compares VIX and VVIX with realized volatility, volatility risk premium, term structure, skew and breadth. A regime label is accepted only when several dimensions describe a coherent state.
Downstream research use
Regimes adjust the interpretation of stock momentum, premium richness and event risk. They are context variables for sizing research assumptions and testing robustness, not deterministic instructions to buy or sell volatility.
Research method
- Normalize VIX and VVIX with rolling percentiles and changes over multiple horizons.
- Classify joint states such as calm/stable, calm/fragile, stressed/accelerating and stressed/stabilizing.
- Cross-check the label against realized volatility, term structure, skew, breadth and event calendars.
- Evaluate how conclusions change under neighboring regimes rather than optimizing one threshold.
Boundaries and limitations
VIX and VVIX are derived from option prices and contain risk premia, positioning and liquidity effects. Their history does not guarantee a stable future distribution, and fixed thresholds can age quickly.
Research takeaway
VIX and VVIX are most valuable as a two-dimensional state map: the level of expected volatility and the instability of that expectation.
