Estudo comparativo de métodos lattice para precificação de opções do mercado financeiro

Abstract

The concept of option comes from the negotiable right of buying or selling an asset with a predetermined future price. The option pricing, which consists in determining the premium (price), is a crucial problem the option theory tackles with. In an attempt to solve this problem, one of the most used models in Finance was developed, the Black and Scholes model. However, this method is inefficient in pricing options where there is dependence of the way followed by the asset price. This work aimed to implement the lattice based models (binomial and trinomial) and verify their utilization in pricing european, american and barrier options.
