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. In addition, it has a semi-closed form solution for European options.

We will introduce the first two models in Chapter 2, and, we will illustrate the Heston model, which was introduced by Steven L. Heston in his dissertation A Closed-Form Solution for Options with Stochastic Volatility with Applications to Bond and Currency Options(1993) , in detail. Heston Simulation 3 2 Heston Model Basics 2.1 SDE and basic properties The Heston model is defined by the coupled two-dimensional SDE dX(t)/X(t)= V(t)dW X(t), (1) dV(t)=κ(θ−V(t))dt+ε V(t)dW V (t), (2) where κ,θ,εare strictly positive constants, and whereW X andW V are scalar Brownian motions in some probability measure; we assume that dW X(t)·dW Heston’s stochastic volatility model (1993) is specified as followed dS(t) S(t) = µdt + V(t)dW 1, (1.1) dV(t) = κ(θ− V(t))dt + σ V(t)dW 2. (1.2) To take into account leverage effect, Wiener stochastic processes W 1,W 2 should be correlated dW 1· dW 2 = ρdt. The stochastic model (1.2) for the variance is related to the square-root process of Feller (1951) and Cox, Heston model was one of the first models that allowed a calibration to real market data using thee semi-closed form solution for European call and put option prices. In Heston model, one cas also consider a correlation between the asset price and the volatility process as for example opposed to Stein and Stein [4] . 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.

These are the top rated real world Python examples of quantlibmodelsequityheston_model.HestonModel extracted from open source projects. You can rate examples to help us improve the quality of examples. In order to price the option using the Heston model, we first create the Heston process. In order to create the Heston process, we use the parameter values: mean reversion strength kappa = 0.1, the spot variance v0 = volatility*volatility = 0.04, the mean reversion variance theta=v0, volatility of volatility sigma = 0.1 and the correlation between the asset price and its variance is rho = -0.75.
