Calibration of the Heston model together with the recent approximative fractional stochastic volatility model is briefly described and compared also in the author’s papers [13, 14], where only calibration results are presented. In this paper we focus on the Heston model only, for which we deeply compare not only calibration techniques, but

The stochastic volatility model of Heston [2] is one of the most popular equity option pricing models. This is due in part to the fact that the Heston model produces call prices that are in closed form, up to an integral that must evaluated numerically. In this Note we present a complete derivation of the Heston model. 1 Heston Dynamics

The Heston model also allows modeling the statistical dependence between the asset returns and the volatility which have been empirically shown to have an inverse relationship. Calibration. The calibration of the Heston model is often formulated as a least squares problem, with the objective function minimizing the difference between the prices observed in the market and those calculated from the Heston model. The prices are typically those of vanilla options.

As opposed to simpler one-dimensional models, Heston model calibration is a multidi-mensional optimization problem with ﬁve degrees of freedom given by q:= (n0,n,r,k,s)T.

4 Calibration of Heston’s Model to Market Data With the now stable implementation of the closed-form solution we are able to calibrate the models to some traded plain vanilla calls. 4.1 Calibration scheme We decide to do a least squared error fit in the following way. Let τ 1,τ 2,,τ M be some times to maturities with fwd 1,fwd 2,,fwd M The Heston model is one of the most popular stochastic volatility models for derivatives pricing. The model proposed by Heston (1993) takes into account non-lognormal distribution of the assets returns, leverage e ect and the important mean-reverting property of volatility.
