New to this release are constant maturity IV readings at various delta levels, forward volatilities and component weighted averages. Forward volatility is a measure of the implied volatility over a period in the future extracted from IV at the beginning of that period and the end of that period. Flat forward volatility is a measure of the implied volatility over a period in the future using theoretical pricing relationships from IV at the beginning of that period and the end of that period. Comparing these two methods of calculating forward volatilities present a unique and powerful way to isolate outliers in the market.
