Following Boukai (2021) we present the Generalized Gamma (GG) distribution as a possible RND for modeling European options prices under Heston's (1993) stochastic volatility (SV) model. This distribution is seen as especially useful in situations in which the spot's price follows a negatively skewed distribution and hence, Black-Scholes based (i.e. the log-normal distribution) modeling is largely inapt. We apply the GG distribution as RND to modeling current market option data on three large… 



On the RND under Heston's Stochastic Volatility Model

We consider Heston's (1993) stochastic volatility model for valuation of European options to which (semi) closed form solutions are available and are given in terms of characteristic functions. We

Empirical Performance of Alternative Option Pricing Models

Substantial progress has been made in extending the Black-Scholes model to incorporate such features as stochastic volatility, stochastic interest rates and jumps.On the empirical front, however, it

Estimating the Implied Risk Neutral Density for the U.S. Market Portfolio

The market's risk neutral probability distribution for the value of an asset on a future date can be extracted from the prices of a set of options that mature on that date, but two key technical


Modifying the distributional assumptions of the Black-Scholes model is one way to accommodate the skewness of underlying asset returns. Simple models based on the compensated gamma and Weibull

How Much is your Strangle Worth? On the Relative Value of the delta-Symmetric Strangle under the Black-Scholes Model

Trading option strangles is a highly popular strategy often used by market participants to mitigate volatility risks in their portfolios. In this paper we propose a measure of the relative value of a

Risk-Neutral Densities: A Review

Trading in options with a wide range of exercise prices and a single maturity allows a researcher to extract the market's risk-neutral density (RND) over the underlying price at expiration. The RND

The little Heston trap

For the first specification of the characteristic function it is proved that stability is guaranteed under the full dimensional and unrestricted parameter space and it is shown that for nearly any parameter choice, instabilities will occur for large enough maturities.

Calibration and simulation of Heston model

A novel calibration procedure is provided that incorporates the usage of approximation formula and outperforms significantly other existing calibration methods and improves the QE scheme by adapting the antithetic variates technique for variance reduction.

Stock Price Distributions with Stochastic Volatility: An Analytic Approach

We study the stock price distributions that arise when prices follow a diffusion process with a stochastically varying volatility parameter. We use analytic techniques to derive an explicit

A Closed-Form Solution for Options with Stochastic Volatility with Applications to Bond and Currency Options

I use a new technique to derive a closed-form solution for the price of a European call option on an asset with stochastic volatility. The model allows arbitrary correlation between volatility and
