Dynamic equicorrelation stochastic volatility [PDF]

open access: yesComputational Statistics & Data Analysis, 2016
A multivariate stochastic volatility model with dynamic equicorrelation and cross leverage effect is proposed and estimated. Using a Bayesian approach, an efficient Markov chain Monte Carlo algorithm is described where we use the multi-move sampler, which generates multiple latent variables simultaneously.

Dealing with Stochastic Volatility in Time Series Using the R Package stochvol [PDF]

open access: yes, 2016
The R package stochvol provides a fully Bayesian implementation of heteroskedasticity modeling within the framework of stochastic volatility. It utilizes Markov chain Monte Carlo (MCMC) samplers to conduct inference by obtaining draws from the posterior ...

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 ...

Multipower Variation and Stochastic Volatility [PDF]

open access: yes, 2006
In this brief note we review some of our recent results on the use of high frequency financial data to estimate objects like integrated variance in stochastic volatility models. Interesting issues include multipower variation, jumps and market microstructure effects.

Pricing Collar Options with Stochastic Volatility

open access: yesDiscrete Dynamics in Nature and Society, 2017
This paper studies collar options in a stochastic volatility economy. The underlying asset price is assumed to follow a continuous geometric Brownian motion with stochastic volatility driven by a mean-reverting process.

Medidas alternativas de volatilidad en el mercado de valores peruano

open access: yesRevista de Análisis Económico y Financiero, 2019
This document seeks to compare the main volatility calculation methodologies for the Peruvian stock market. Three volatility calculation methods are presented, the EWMA model, the GARCH model and the Stochastic Volatility (SV) model.

Double-jump stochastic volatility model for VIX: evidence from VVIX

open access: yes, 2015
The paper studies the continuous-time dynamics of VIX with stochastic volatility and jumps in VIX and volatility. Built on the general parametric affine model with stochastic volatility and jump in logarithm of VIX, we derive a linear relation between ...

Bootstrapping Non-Stationary Stochastic Volatility [PDF]

open access: yesSSRN Electronic Journal, 2019
In this paper we investigate how the bootstrap can be applied to time series regressions when the volatility of the innovations is random and non-stationary. The volatility of many economic and financial time series displays persistent changes and possible non-stationarity.

Asymptotics for Rough Stochastic Volatility Models [PDF]

open access: yesSIAM Journal on Financial Mathematics, 2016
Using the large deviation principle (LDP) for a rescaled fractional Brownian motion $B^H_t$, where the rate function is defined via the reproducing kernel Hilbert space, we compute small-time asymptotics for a correlated fractional stochastic volatility ...
