The importance of modelling futures dynamics in commodity index derivatives
Index-based and underlying-based pricing methods for commodity derivatives are presented
The importance of being scrambled: supercharged quasi-Monte Carlo
The authors propose a randomized quasi-Monte Carlo method which outperforms both the Monte Carlo and standard quasi-Monte Carlo methods.
Smile-consistent basket skew
An analytic approximation for the implied volatility surface of basket options is introduced
Vega decomposition for the LV model: an adjoint differentiation approach
Introducing an algorithm for computing vega sensitivities at all strikes and expiries
Singular exotic perturbation
A solution based on local volatility and sensitivities is proposed to calculate exotics' prices
A new fast local volatility model
A local volatility model based on the Bass construction and alternative to Dupire-style models is introduced
Optimal transport for model calibration
Volatility models and SPX/VIX joint dynamics are calibrated using optimal transport theory
Probabilistic machine learning for local volatility
In this paper, the authors propose to approach the calibration problem of local volatility with Bayesian statistics to infer a conditional distribution over functions given observed data.
Sticky varswaps
Bergomi's skew-stickiness ratio is extended to the setting of variance swaps
The step stochastic volatility model
Extreme short-dated skew can be obtained by decomposing it in two parts
What is the volatility of an Asian option?
An adjustment for the volatility smile in Asian options is proposed
Finite difference schemes with exact recovery of vanilla option prices
A model unifies the classic local vol and binomial trees to accurately price options
A new arbitrage-free parametric volatility surface
A new arbitrage-free volatility surface with closed-form valuation and local volatility is introduced
One-dimensional Markov-functional models driven by a non-Gaussian driver
The aim of this paper is to move away from a Gaussian assumption and to provide new algorithms that can be used to implement a Markov-functional model driven by a more general class of one-dimensional diffusion processes.
The interplay between stochastic volatility and correlations in equity autocallables
Study shows issues with pricing autocallables using SLV
Local stochastic volatility: shaken, not stirred
Dominique Bang introduces a novel LSV approach to term distribution modelling
The optimal investment problem in stochastic and local volatility models
This paper considers the classical optimal investment allocation problem of Merton through the lens of some more modern approaches, such as the stochastic volatility and local volatility models.
Knocking out corridor variance
Amine Ahallal and Olaf Torne add a knock-out barrier to the standard corridor variance swap
Bermudan swaption model risk analysis: a local volatility approach
This paper seeks to contribute a simple and (almost) model-free way of assessing the economic value of the Bermudan exercise right derived from a “minimal” local volatility enhanced interest rate model.
Equity modelling with local stochastic volatility and stochastic discrete dividends
SocGen quants calibrate local stochastic volatility models with stochastic dividends
The swap market model with local stochastic volatility
An easy to calibrate and accurate swap market model is proposed
