Abstract:In this paper we present a stable numerical method for the linear complementary problem arising from American put option pricing. The numerical method is based on a hybrid finite difference spatial discretization on a piecewise uniform mesh and an implicit time stepping technique. The scheme is stable for arbitrary volatility and arbitrary interest rate. We apply some tricks to derive the error estimates for the direct application of finite difference method to the linear complementary problem. We use the Sing… Show more
“…Further, we compare the presented l 1 FVM with a more straightforward approach to the original penalized problem on the truncated domain [0, 4E] by centred-space discretization of the first derivative away from the degeneration and one-sided discretization in the degeneration region to ensure the M-matrix property [5] on uniform grid. Again, the l 1 penalization and fully implicit time discretization are used as for the Crank-Nicolson time stepping one may observe oscillations when using centred-space discretization.…”

“…The known function σ (t) characterizes the volatility of the asset, r(t) is the interest rate, d(S, t) is the dividend function and V * is the payoff, given by V (S, T ) = V * (S) = max(S − E, 0) for call option (V * (S) = max(E − S, 0) for put option). Various numerical methods are developed for the LCP (1) [4][5][6]16,18]. Introduced in computational finance by Zvan et al [25], the penalty method is regarded as solid alternative to these popular algorithms.…”
We study theAmerican option pricing linear complementarity problem (LCP), transformed on finite interval as it is initially defined on semi-infinite real axis. We aim to validate this transformation, investigating the well-posedness of the resulting problem in weighted Sobolev spaces. The monotonic penalty method reformulates the LCP as a semi-linear partial differential equation (PDE) and our analysis of the penalized problem results in uniform convergence estimates. The resulting PDE is further discretized by a fitted finite volume method since the transformed partial differential operator degenerates on the boundary. We show solvability of the semi-discrete and fully discrete problems. The Brennan-Schwarz algorithm is also presented for comparison of the numerical experiments, given in support to our theoretical considerations.

“…Here, we apply the central difference scheme on a piecewise uniform mesh [16,17] to discrete problem (13) and apply the implicit Euler scheme to discrete problem (14). The matrices associated with discrete operators are M-matrices, which ensure that the scheme is stable for arbitrary volatility and arbitrary interest rate without any extra conditions.…”

“…Furthermore, the uniform mesh on the transformed interval will lead to the originally grid points concentrating around = 0 inappropriately. We have proposed robust difference schemes for the BlackScholes equation, which is based on a central difference spatial discretization on a piecewise uniform mesh and an implicit time stepping technique [16,17].…”
We propose a fast and stable numerical method to evaluate two-dimensional partial differential equation (PDE) for pricing arithmetic average Asian options. The numerical method is deduced by combining an alternating-direction technique and the central difference scheme on a piecewise uniform mesh. The numerical scheme is stable in the maximum norm, which is true for arbitrary volatility and arbitrary interest rate. It is proved that the scheme is second-order convergent with respect to the asset price. Numerical results support the theoretical results.
“…Since the option pricing in a market is dependent on other markets, the multidimensional Black Scholes equation is more efficient than the one dimensional version. There are various methods to find the solution of multidimensional Black Scholes model; for example, a radical basic function (RBF) method [2][3][4][5][6], the Mellin transform method [7], finite different method [8][9][10][11][12], a collection method with the quantic B-spline function [13], and homotopy perturbation method (HPM) [14,15].…”
Abstract:The Black Scholes model is a well-known and useful mathematical model in financial markets. In this paper, the two-dimensional Black Scholes equation with European call option is studied. The explicit solution of this problem is carried out in the form of a Mellin-Ross function by using Laplace transform homotopy perturbation method. The solution example demonstrates that the proposed scheme is effective.
