VIX-Style Metrics
VIX-style volatility metrics provide insight into market fear, uncertainty, and expected volatility by analyzing the implied volatility term structure and options pricing across different assets.
Overview
VIX-style metrics measure the market’s expectation of future volatility by analyzing the prices of options across multiple strikes and expirations. These indicators serve as “fear gauges” and provide insights into market sentiment and potential turning points.
Core VIX Concepts
What VIX Measures
Implied Volatility Expectation:
- 30-day forward-looking volatility estimate
- Market’s expectation of price movement
- Annualized percentage volatility
- Based on SPX options pricing
Fear vs Greed Indicator:
- Low VIX (< 20): Complacency, low fear
- Moderate VIX (20-30): Normal market conditions
- High VIX (30-40): Elevated fear and uncertainty
- Extreme VIX (> 40): Panic, extreme fear
Individual Stock VIX Calculation
Methodology
For each stock, the platform calculates VIX-style metrics using:
Options Chain Analysis:
- Multiple strikes across the money
- Near-term and next-term expirations
- Both calls and puts included
- Real-time implied volatility data
Calculation Steps:
- Select appropriate expiration dates
- Calculate forward index value
- Calculate volatility for each expiration
- Interpolate to 30-day constant maturity
- Annualize the result
Formula Components:
VIX = 100 × √(2/T × Σ(ΔKi/Ki² × Q(Ki)) - 1/T × (F/K₀ - 1)²)
Where:
- T = Time to expiration
- Ki = Strike price
- Q(Ki) = Option price at strike Ki
- F = Forward index value
- K₀ = First strike below forward value
Historical VIX Analysis

Volatility Regimes:
- Low volatility periods (VIX < 15)

- Event risk vs structural risk
- Trading vs investment timeframes
Signal Generation:
- VIX9D > VIX: Near-term stress
- VIX9D < VIX: Forward concern
- Converging levels: Stabilization
- Diverging levels: Regime change
