Keywords: Heston model; calibration; European options; Shannon wavelets 1. Introduction The Heston model is a well-known stochastic volatility (SV) model for driving the dynamics of the assets. In order to use the Heston model, we need to calibrate its five parameters to real-market data. The goal of calibrating a model using market data is to

Abstract The Heston stochastic volatility model explains volatility smile and skewness while the Black-Scholes model assumes a constant volatility. With the explicit option pricing formula derived by Heston, we use the Least Squares Fit to calibrate and do a robustness check as our back test. The model implements the calibration of Heston stochastic volatility model.

(NIG-CIR) For the analysis of many exotic financial derivatives, the Heston model, a stochastic volatility model, is widely used.

2.1The Heston Model The Heston model [5] introduced in 1993 is a stochastic volatility model in which the risk neutral stock price dynamics are given by: dS t= (r q)S tdt+ ˙ tS tdW (1) t (2.1a) d˙2 t = k( ˙2 t)dt+ ˙ tdW (2) t (2.1b) Cov[dW(1) t dW (2) t] = ˆdt (2.1c) Here ris the risk neutral interest rate and W(1) t and W (2) t are two correlated standard Brow-
Heston Model as an example we show how such a calibration can be carried out. We also present an easy to implement genetic algorithm and provide calibration results for the daily stock returns of the DAX and the S&P 500. 1 The Heston Model and it’s transition density The Heston Model (HM) suggested by Heston (1993) is often seen as the rst Numerical results for optimizing some test functions and a model calibration based on true Heston parameters is presented in Chapter 5. Chapter 6 This chapter finally presents several applications of the Heston model for pricing and managing some exotic derivative securities, like the variance swap or the cliquet option. Delft, December 2007 Model and calibration risks for the Heston model Florence Guillaume Wim Schoutensy June 10, 2010 Abstract Parameters of equity pricing models, such as the Heston’s stochastic volatility model, have to be calibrated every day to new market data of European vanilla options by minimizing a particular functional. Heston stochastic volatility model cannot be traced, so the traditionalmaximum likelihood estimation cannot be applied to estimate Heston model directly. Of course, on can always use option panel data to back out structure parameters, as Bakshi, Cao and Chen (1997) and Nandi (1998) do.
