Closed-Form Formula for the Conditional Moments of Log Prices under the Inhomogeneous Heston Model

open access: yesComputation, 2022
Several financial instruments have been thoroughly calculated via the price of an underlying asset, which can be regarded as a solution of a stochastic differential equation (SDE), for example the moment swap and its exotic types that encourage investors

FX smile in the Heston model [PDF]

open access: yes, 2011
The Heston model stands out from the class of stochastic volatility (SV) models mainly for two reasons. Firstly, the process for the volatility is non-negative and mean-reverting, which is what we observe in the markets. Secondly, there exists a fast and easily implemented semi-analytical solution for European options.

Filtration of parameters of the Heston model

open access: yesСистеми обробки інформації, 2020
In this article we consider the Heston model of the stock price behaviour. While the volatility of the model is the non-linear function of another stochastic unobservable function, that is why we consider linearizing all non-linear functions of the model.

Closed-form portfolio optimization under GARCH models

open access: yesOperations Research Perspectives, 2022
This paper develops an approximate closed-form optimal portfolio allocation formula for a spot asset whose variance follows a GARCH(1,1) process. We consider an investor with constant relative risk aversion (CRRA) utility who wants to maximize the ...

Numerical Simulation of the Heston Model under Stochastic Correlation

open access: yesInternational Journal of Financial Studies, 2017
Stochastic correlation models have become increasingly important in financial markets. In order to be able to price vanilla options in stochastic volatility and correlation models, in this work, we study the extension of the Heston model by imposing ...

Series Expansions and Direct Inversion for the Heston Model [PDF]

open access: yesSIAM Journal on Financial Mathematics, 2021
Efficient sampling for the conditional time integrated variance process in the Heston stochastic volatility model is key to the simulation of the stock price based on its exact distribution. We construct a new series expansion for this integral in terms of double infinite weighted sums of particular independent random variables through a change of ...

Optimal investment strategy for DC pension plan with inflation risk under the hybrid stochastic volatility model

open access: yesSystems Science & Control Engineering, 2023
In this paper, we investigate an optimal investment strategy for defined-contribution (DC) pension plan under hybrid stochastic volatility (Heston–Hull–White) model, taking account of the inflation risk and the stochastic salary.

Inventory effects on the price dynamics of VSTOXX futures quantified via machine learning

open access: yesJournal of Finance and Data Science, 2021
The VSTOXX index tracks the expected 30-day volatility of the EURO STOXX 50 equity index. Futures on the VSTOXX index can, therefore, be used to hedge against economic uncertainty.

Optimal dynamic mean-variance asset-liability management under the Heston model

open access: yesAdvances in Difference Equations, 2018
This paper studies a continuous-time mean-variance asset-liability management problem under the Heston model. Specifically, an asset-liability manager is allowed to invest in a risk-free asset and a risky asset whose price process is governed by the ...
