چکیده
This paper deals with a new numerical method for the approximation of early exercise boundary in American option pricing problem. In more detail, using mean-value theorem integrals, we provide flexible algorithm that allows reaching accurate solution fewer calculations rather than other previously described methods.

Evaluating Approximations to the Optimal Exercise Boundary for American Options
We consider series solutions for the location of the optimal exercise boundary of an American option close to expiry. By using Monte Carlo methods, we compute the expected value of an option if the holder uses the approximate location given by such a series as his exercise strategy, and compare this value to the actual value of the option. This gives an alternative method to evaluate approximat...
متن کاملApproximating Early Exercise Boundaries for American Options
American options are different to European style options in that the contract buyer has the right to exercise the option at any time on or before maturity . The freedom to exercise an American option whenever the holder wishes, introduces a boundary problem to solving the Black-Scholes equation popularly used to price the European options. The contract holder will ideally, of course, only exerc...
متن کاملSensitivity Analysis of the Early Exercise Boundary for American Style of Asian Options
In this paper we analyze American style of floating strike Asian call options belonging to the class of financial derivatives whose payoff diagram depends not only on the underlying asset price but also on the path average of underlying asset prices over some predetermined time interval. The mathematical model for the option price leads to a free boundary problem for a parabolic partial differe...
متن کاملAn Approximate Formula for Pricing American Options
An approximate formula for pricing American options along the lines of MacMillan [1986] and Barone-Adesi and Whaley [1987] is presented. This analytical approximation is as efficient as the existing ones, but it is remarkably more accurate. In particular, it yields good results for long maturity options for which the existing analytical ones fare poorly. It is also demonstrated that this approx...
متن کاملNumerical Solution of Integral Equation for the Early Exercise Boundary of American Put Option
The paper is focused on numerical approximation of early exercise boundary within American put option pricing problem. Assuming non-dividend paying, American put option leads to two disjunctive regions, a continuation one and a stopping one, which are separated by an early exercise boundary. We present variational formulation of American option problem with special attention to early exercise a...
