O objectivo desta dissertação de Mestrado é a análise, implementação e comparação de resultados obtidos no pricing de double barrier options (sem rebates), seguindo a metodologia proposta por Geman e Yor [6] em 1996. O modelo utiliza uma abordagem probabilística, de forma a quantificar a probabilidade das barreiras serem atingidas. Ao longo do desenvolvimento, até à expressão final, é utilizado o Teorema de Girsanov assim como transformadas de Laplace. A implementação do modelo é feita em MATLAB e um dos principais desafios é o cálculo da inversa da transformada de Laplace.
The purpose of this work is the analysis, implementation and comparison of results obtained in the pricing of double barrier options (without rebates payment), following the methodology proposed by Geman and Yor [6] in 1996. The model uses a probabilistic approach in order to quantify the barrier hit probability. Throughout the development, until the final expression, we use the Girsanov theorem and Laplace transforms. The model implementation is done in MATLAB and a key challenge is the calculation of the inverse Laplace transform.
