Jump Driven Risk Model Performance in Cryptocurrency Market

open access: yesInternational Journal of Financial Studies, 2020
This paper aims at identifying a validated risk model for the cryptocurrency market. We propose a stochastic volatility model with co-jumps in return and volatility (SVCJ) to highlight the role of jumps in returns and volatility in affecting Value-at ...

Option Pricing under the Jump Diffusion and Multifactor Stochastic Processes

open access: yesJournal of Function Spaces, 2019
In financial markets, there exists long-observed feature of the implied volatility surface such as volatility smile and skew. Stochastic volatility models are commonly used to model this financial phenomenon more accurately compared with the conventional

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 ...

Closed-form approximate solutions for stop-loss and Russian options with multiscale stochastic volatility

open access: yesAIMS Mathematics, 2023
In general, derivation of closed-form analytic formulas for the prices of path-dependent exotic options is a challenging task when the underlying asset price model is chosen to be a stochastic volatility model.

Model of Continuous Random Cascade Processes in Financial Markets

open access: yesFrontiers in Physics, 2020
This article presents a continuous cascade model of volatility formulated as a stochastic differential equation. Two independent Brownian motions are introduced as random sources triggering the volatility cascade: one multiplicatively combines with ...

The Heston stochastic volatility model in Hilbert space

open access: yes, 2017
We extend the Heston stochastic volatility model to a Hilbert space framework. The tensor Heston stochastic variance process is defined as a tensor product of a Hilbert-valued Ornstein-Uhlenbeck process with itself. The volatility process is then defined

Stochastic Volatility [PDF]

open access: yes, 1995
This paper prepared for the Handbook of Statistics (Vol.14: Statistical Methods in Finance), surveys the subject of stochastic volatility. the following subjects are covered: volatility in financial markets (instantaneous volatility of asset returns, implied volatilities in option prices and related stylized facts), statistical modelling in discrete ...
