Asymptotics of Forward Implied Volatility [PDF]
We prove here a general closed-form expansion formula for forward-start options and the forward implied volatility smile in a large class of models, including the Heston stochastic volatility and time-changed exponential L\'evy models.

Normalization for Implied Volatility [PDF]
We study specific nonlinear transformations of the Black-Scholes implied volatility to show remarkable properties of the volatility surface. Model-free bounds on the implied volatility skew are given. Pricing formulas for the European options which are written in terms of the implied volatility are given.

The stock implied volatility and the implied dividend volatility [PDF]
This study compares the information on the implied volatility surface of a stock-index with the corresponding information on the implied volatility surface of the index dividend futures. We outline an optimisation technique for comparing implied volatility estimates based on the Black-Scholes model, Black model and a model-free approach, for stock ...

Convergence of At-The-Money Implied Volatilities to the Spot Volatility [PDF]
We study the convergence of at-the-money implied volatilities to the spot volatility in a general model with a Brownian component and a jump component of finite variation. This result is a consequence of the robustness of the Black-Scholes formula and of the central limit theorem for martingales.

Implied Volatility and Risk Aversion in a Simple Model with Uncertain Growth [PDF]
We show that a simple equilibrium model with uncertain growth is able to simultaneously generate patterns in implied volatility and risk aversion that are similar to the ones observed in the data.parameter uncertainty, option pricing, implied volatility,

The implied volatility smirk [PDF]
This paper provides an industry standard on how to quantify the shape of the implied volatility smirk in the equity index options market. Our local expansion method uses a second-order polynomial to describe the implied volatility–moneyness function and relates the coefficients of the polynomial to the properties of the implied risk-neutral ...

The Analysis of Implied Volatilities [PDF]
The analysis of volatility in financial markets has become a first rank issue in modern financial theory and practice: Whether in risk management, portfolio hedging, or option pricing, we need to have a precise notion of the market’s expectation of volatility.
