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

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

Time Dependent Heston Model [PDF]
SIAM 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 ...

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

Numerical Simulation of the Heston Model under Stochastic Correlation
International 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 ...
