Index option returns and systemic equity risk

open access: yesJournal of Finance and Data Science, 2018
In an environment characterized by stochastic variances and correlations, we demonstrate through construction of the equilibrium index option value from constituent components, that the generalized PDE identifies the stochastic elements differentially ...

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 ...

Does Expectation of Correlation Breakdown in Financial Market Fulfill Itself?

open access: yesDiscrete Dynamics in Nature and Society, 2015
This paper develops a model appeared in the literature whose focus was the way rational risk averse investors anticipate the correlation breakdowns of asset returns in periods of excess demand.

The Reactive Volatility Model [PDF]

open access: yes, 2013
We present a new volatility model, simple to implement, that includes a leverage effect whose return-volatility correlation function fits to empirical observations.

Irreducible many-body correlations in topologically ordered systems

open access: yesNew Journal of Physics, 2016
Topologically ordered systems exhibit large-scale correlation in their ground states, which may be characterized by quantities such as topological entanglement entropy.

Quanto Implied Correlation in a Multi-LLvy Framework [PDF]

open access: yesSSRN Electronic Journal, 2015
In this paper we apply the multivariate construction for Lévy processes introduced by Ballotta and Bonfiglioli (2014) to propose an integrated model for the joint dynamics of FX exchange rates and asset prices. We show that the proposed construction is consistent in terms of symmetries with respect to inversion and triangulation, and provides an ...

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...
