Merton’s portfolio problem under Volterra Heston model [PDF]

open access: yesFinance Research Letters, 2021
This paper investigates Merton's portfolio problem in a rough stochastic environment described by Volterra Heston model. The model has a non-Markovian and non-semimartingale structure. By considering an auxiliary random process, we solve the portfolio optimization problem with the martingale optimality principle.

Modeling of Tehran Stock Exchange Overall Index by Heston Stochastic Differential Equation [PDF]

open access: yesFaslnāmah-i Pizhūhish/Nāmah-i Iqtisādī, 2014
In this study, overall index of Tehran Stock Exchange is modeled by Heston stochastic differential equations and its performance is measured. To do this, after a brief introduction of stochastic differential equations, Heston model is explained in more ...

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 ...

Time Dependent Heston Model [PDF]

open access: yesSIAM Journal on Financial Mathematics, 2009
The use of the Heston model is still challenging because it has a closed formula only when the parameters are constant [Hes93] or piecewise constant [MN03]. Hence, using a small volatility of volatility expansion and Malliavin calculus techniques, we derive an accurate analytical formula for the price of vanilla options for any time dependent Heston ...

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.

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 ...

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 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.
