Optimal Selling Rule in a Regime Switching Lévy Market

Abstract EN

This paper is concerned with a finite-horizon optimal selling rule problem when the underlying stock price movements are modeled by a Markov switching Lévy process.

Assuming that the transaction fee of the selling operation is a function of the underlying stock price, the optimal selling rule can be obtained by solving an optimal stopping problem.

The corresponding value function is shown to be the unique viscosity solution to the associated HJB variational inequalities.

A numerical example is presented to illustrate the results.
