ON THE HESTON MODEL WITH STOCHASTIC CORRELATION

International Journal of Theoretical and Applied Finance, 2016
The degree of relationship between financial products and financial institutions, e.g. must be considered for pricing and hedging. Usually, for financial products modeled with the specification of a system of stochastic differential equations, the relationship is represented by correlated Brownian motions (BMs).

The Heston Model

2017
In this chapter we introduce the subject of volatility modelling. Some issues have already been tackled in Kienitz (2014). We start with a short general introduction.

Heston Model: The Variance Swap Calibration

SSRN Electronic Journal, 2013
This paper proposes an alternative methodology to derive starting values for parameters of the Heston model. The term structure of variance swap prices is inferred from the option price surface by means of the spanning option payoff formula given by \textit{D. T. Breeden} and \textit{R. H.

On the Infeasability of the Heston Model

SSRN Electronic Journal, 2020
Heston (1993) is among the progenitors in the literature regarding option pricing under stochastic volatility. This paper seeks to show that, under his own assumptions, Heston's results are less general than previously believed.

A fractional Heston model with

Stochastics, 2016
We present a modification of the classical Heston model, where the volatility process is defined by means of a fractional integration of a diffusion process. Our construction allows us to easily compute a martingale representation for the volatility process.

On Singularities in the Heston Model

SSRN Electronic Journal, 2007
In this note we provide characterization of the singularities of the Heston characteristic function. In particular, we show that all the singularities are pure imaginary.

Complex Logarithms in Heston-Like Models

SSRN Electronic Journal, 2008
Summary: The characteristic functions of many affine jump-diffusion models, such as Heston's stochastic volatility model and all of its extensions, involve multivalued functions such as the complex logarithm. If we restrict the logarithm to its principal branch, as is done in most software packages, the characteristic function can become discontinuous,

Markovian projection onto a Heston model

The Journal of Computational Finance, 2007
We develop a systematic approach to the reduction of dimensionality of smile-enabled models by projecting them onto a displaced version of the two-dimensional Heston process. The projection is the key for deriving efficient, analytical approximations to European option prices in such models.

Calibrating the Heston Model with Differential Evolution

2010
Calibrating option pricing models to market prices often leads to optimisation problems to which standard methods (like such based on gradients) cannot be applied. We investigate one particular example, Heston's stochastic volatility model. We discuss how to price options under this model, and how to calibrate the parameters of the model with a ...
