Smiling under stochastic volatility [PDF]

open access: yes
This paper studies the behavior of the implied volatility function (smile) when the true distribution of the underlying asset is consistent with the stochastic volatility model proposed by Heston (1993). The main result of the paper is to extend previous

Implied Stochastic Volatility Models

open access: yesThe Review of Financial Studies, 2020
Abstract This paper proposes “implied stochastic volatility models” designed to fit option-implied volatility data and implements a new estimation method for such models. The method is based on explicitly linking observed shape characteristics of the implied volatility surface to the coefficient functions that define the stochastic ...

Progress in Strain Engineering of 2D‐Integrated Heterostructures for Ultrasensitive Sensors

open access: yesAdvanced Science, EarlyView.
 . ABSTRACT Two‐dimensional (2D) integrated heterostructures have emerged as a cornerstone in the advancement of next‐generation sensor technologies. These heterostructures, which combine materials with different dimensionalities, have led to significant breakthroughs in sensing performance and device integration.

Induced Garima Stochastic Volatility Models

open access: yesAustrian Journal of Statistics
In the present paper, a stochastic volatility model generated by a first-order induced Garima Markov sequence has been suggested for modeling financial time series. The statistical and probabilistic properties of the suggested model are studied, and the

Semi-Analytical Option Pricing Under Double Heston Jump-Diffusion Hybrid Model

open access: yesJournal of Mathematical Sciences and Modelling, 2018
We examine European call options in the jump-diffusion version of the Double Heston stochastic volatility model for the underlying price process to provide a more flexible model for the term structure of volatility.

Pricing stock options under stochastic volatility and interest rates with efficient method of moments estimation [PDF]

open access: yes
While the stochastic volatility (SV) generalization has been shown to improve the explanatory power over the Black-Scholes model, empirical implications of SV models on option pricing have not yet been adequately tested.

All Organic Fully Integrated Neuromorphic Crossbar Array

open access: yesAdvanced Electronic Materials, EarlyView.
In this work, the first fully integrated crossbar array of electrochemical random‐access memory (ECRAM) that is composed entirely of organic materials is represented. This array can perform inference and in situ parallel training and is capable of classifying linearly separable 2D and 3D classification tasks with high accuracy.

Stochastic Spot/Volatility Correlation in Stochastic Volatility Models and Barrier Option Pricing [PDF]

open access: yes, 2014
Most models for barrier pricing are designed to let a market maker tune the model-implied covariance between moves in the asset spot price and moves in the implied volatility skew.

Stochastic Volatility Models

open access: yes, 2023
I denne avhandlingen ble effektiviteten av Stokastiske Volatilitetsmodeller, med ARMA(p, q) log-volatilitet, undersøkt i forhold til GARCH(p, q) i å forutsi volatiliteten til finansielle tidsserier. Videre var målet å vurdere evnen til SVMer i å fange opp atferden til underliggende finansielle tidsserier.
