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 Carlo simulation of the Heston stochastic process and with the Black-Scholes formula.

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.
Generalized SV models The Heston Model Vanilla Call Option via Heston The Heston model is a typical Stochastic Volatility model which takes (S t;v t;t) = ( v t) and (S t;v t;t) = ˙ p v t, i.e. dS t = S tdt + p v tS tdW 1;t; (3) dv t = ( v t)dt + ˙ p v tdW 2;t; (4) with dW 1;tdW 2;t = ˆdt ; (5) where is the long term mean of v t, denotes the speed of
The Heston Model is one of the most widely used stochastic volatility (SV) models today. Its attractiveness lies in the powerful duality of its tractability and robustness relative to other SV models. This project initially begun as one that addressed the calibration problem of this model. Heston’s system utilizes the properties of a no-arbitrage martingale to model the motion of asset price and volatility. In a martingale, the present value of a financial derivative is equal to the expected future valueofthatderivative,discountedbytherisk-freeinterestrate. 2.1 The Heston Model’s …
