Abstract
In this article, a numeric meall and developed to find the value of an American sales option, based on Black and Scholes (1973) solution for European opcoes and Richardson extrapollator, which calculates the limit of a sequencing of opcoes, whose time intervals tend to be zero. At the beginning of 1970 Black and Scholes (1973) and Merton (1973) developed a partial differential equation, the solution of which determines the value of a European opcao. The border convention would determine the type of option (purchase or sale). Values for the American sales option are calculated, tabulated and compared to the m’etoe of the integracao numerica and the binomial approximate.
