Telegraph Processes and Option Pricing

TL;DR: In this article, the authors propose an asymmetric jump-telegraph process on the line for option pricing in financial modelling and option pricing, which is based on the Telegraph Process on the Line.
Journal ArticleDOI

A jump telegraph model for option pricing

TL;DR: In this paper, the authors introduce a financial market model based on continuous time random motions with alternating constant velocities and jumps occurring when the velocity are switching, which is free of arbitrage if jump directions are in a certain correspondence with the underlying random motion.
Journal ArticleDOI

On the asymmetric telegraph processes

TL;DR: In this article, the authors studied the one-dimensional random motion X = X(t), t ≥ 0, which takes two different velocities with two different alternating intensities, and obtained closed-form formulae for the density functions of X and for the moments of any order.
Journal ArticleDOI

Occupation time distributions for the telegraph process

TL;DR: In this paper, the authors derived the long-term limiting distribution for the one-dimensional telegraph process when the initial location of the process is in the range of subnormal or normal deviations from the origin; in the former case, the limit is given by the arcsine law.
Journal ArticleDOI

Option pricing driven by a telegraph process with random jumps

TL;DR: In this article, a class of financial market models which are based on telegraph processes with alternating tendencies and jumps is proposed. But these models are typically incomplete, but the set of equivalent martingale measures can be described in detail.
