What Does Today's Smile Imply About Future Volatilities (original) (raw)
The paper presents a simple and financially justifiable way to extract from today's plain vanilla option prices the evolution of the smile surface in the (Q) measure. By combining this information with (P)-measure estimation of the dependence of implied volatility on the underlying, one can i) obtain information about the existence and magnitude of a volatility risk premium; ii) devise trading strategies; iii) price options such as Forward Volatility Agreements (FVAs).

Option Bounds and the Pricing of the Volatility Smile
Review of Derivatives Research, 2000
This paper presents a new approach forthe estimation of the risk-neutral probability distribution impliedby observed option prices in the presence of a non-horizontalvolatility smile. This approach is based on theoretical considerationsderived from option pricing in incomplete markets. Instead ofa single distribution, a pair of risk-neutral distributions areestimated, that bracket the option prices defined by the volatilitybid/ask midpoint. These distributions define upper and lowerbounds on option prices that are consistent with the observableoption parameters and are the tightest ones possible, in thesense of minimizing the distance between the option upper andlower bounds. The application of the new approach to a sampleof observations on the S&P 500 option market showsthat the bounds produces are quite tight, and also that theirderivation is robust to the presence of violations of arbitragerelations in option quotes, which cause many other methods tofail.
