The CME Group Volatility Index (CVOL) delivers the first ever cross-asset class family of implied volatility indices based on simple variance. Using our proprietary simple variance methodology that assigns equal weighting to strikes across the entire implied volatility curve, the CVOL Index produces a more representative measure of the market’s expectation of 30-day forward risk.

How the CVOL Index works
CVOL Indices measure the expected risk or volatility of an underlying futures contract based on the information contained in the prices of options on that underlying futures contract.
The concept of simple variance can be used to improve existing measures of expected volatility. CVOL indexes use an improved simple variance estimation method to provide expected volatility metrics derived from the entire Implied Volatility Curve. The original simple variance methodology was introduced in two papers by Ian Martin, Professor of Finance at the London School of Economics, which provide more information about simple variance and its applications: Simple Variance Swaps and What is the Expected Return on the Market?"
