An empirical model of volatility of returns and option pricing [PDF]

open access: yes
This paper reports several entirely new results on financial market dynamics and option pricing We observe that empirical distributions of returns are much better approximated by an exponential distribution than by a Gaussian.

Galerkin approach by certain shifted Jacobi polynomials for solving the time-fractional Black-Scholes equation

open access: yesBoundary Value Problems
This work presents a spectral Galerkin approach for solving the time-fractional Black-Scholes equation (TFBSE) used in option pricing models, considering memory effects. We use certain shifted Jacobi polynomials as the basis functions.

A NEW MODEL FOR STOCK PRICE MOVEMENTS [PDF]

open access: yes
This paper presents a new alternative diffusion model for asset price movements. In contrast to the popular approach of Brownian Motion it proposes Deterministic Diffusion for the modelling of stock price movements.

Analysis of a Finite Difference Method for a Time-Fractional Black–Scholes Equation

open access: yesFractal and Fractional
The goal of this paper is to give an error analysis of a finite difference method for a time-fractional Black–Scholes equation with weakly singular solutions.

Optimal Algebras and Novel Solutions of Time-Fractional 2+1−D European Call Option Model

open access: yesDiscrete Dynamics in Nature and Society
In this article, we analyse the time-fractional 2+1−D Black–Scholes model for European call options by employing Lie symmetry analysis. We derive the infinitesimal transformations and classify the optimal systems.

Fractional Black–Scholes Under Memory Effects: A Sixth-Order Local RBF–FD Scheme with Integrated Multiquadric Kernels

open access: yesAxioms
In this work, a high-order meshless framework is developed for the numerical resolution of the temporal–fractional Black–Scholes equation arising in option pricing with long-memory effects.
