What is a Volatility Surface?
A volatility surface maps implied volatility as a function of both strike price and time to expiration. It captures the full landscape of how the market prices risk across different scenarios and time horizons.
SVI Calibration: FlashAlpha uses Stochastic Volatility Inspired (SVI) parameterization to fit a smooth, arbitrage-free surface to raw market quotes. This eliminates noise while preserving the true shape of the smile.
Reading the Heatmap
- Cool colors (blue): Low IV — options are relatively cheap. Potential for long vol positions.
- Warm colors (red/orange): High IV — options are expensive. Consider selling premium or look for relative value.
- Spot row: Highlighted row shows IV at the current stock price. Compare across expirations to see term structure.
- Wings: IV rising sharply at far OTM strikes indicates tail risk pricing or squeeze potential.
