Estimating the parameters of 3/2 stochastic volatility model with jump [PDF]

Mathematics and Modeling in Finance, 2023
The financial markets reveal stylized facts that could not be captured by Black-Scholes partial differential equations (PDEs).  In this research, we investigate 3/2 stochastic volatility to pricing options which is more compatible with the interpretation

Capturing the volatility smile: parametric volatility models versus stochastic volatility models [PDF]

Public and Municipal Finance, 2016
Black-Scholes option pricing model (1973) assumes that all option prices on the same underlying asset with the same expiration date, but different exercise prices should have the same implied volatility.

Option Pricing under Two-Factor Stochastic Volatility Jump-Diffusion Model

Complexity, 2020
Empirical evidence shows that single-factor stochastic volatility models are not flexible enough to account for the stochastic behavior of the skew, and certain financial assets may exhibit jumps in returns and volatility.

Estimation of Realized Asymmetric Stochastic Volatility Models Using Kalman Filter

Econometrics, 2023
Despite the growing interest in realized stochastic volatility models, their estimation techniques, such as simulated maximum likelihood (SML), are computationally intensive.

Jump Driven Risk Model Performance in Cryptocurrency Market

International 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 ...

A novel stochastic modeling framework for coal production and logistics through options pricing analysis

Financial Innovation, 2023
We propose a novel stochastic modeling framework for coal production and logistics using option pricing theory. The problem of valuing the inherent real optionality a coal producer has when mining and processing thermal coal is modelled as pricing spread

Valuation of Commodity-Linked Bond with Stochastic Convenience Yield, Stochastic Volatility, and Credit Risk in an Intensity-Based Model

Mathematics, 2023
In this study, we consider an intensity-based model for pricing a commodity-linked bond with credit risk. Recently, the pricing of a commodity-linked bond with credit risk under the structural model has been studied.

Medidas alternativas de volatilidad en el mercado de valores peruano

Revista 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.
