[en] OPTIMIZATION OF PORTFOLIO STRUCTURES / [pt] ESTRUTURAÇÃO ÓTIMA DE CARTEIRAS DE INVESTIMENTOS COM OPÇÕES

MARIA LUIZA DE ANDRADE MAIA 29 December 2006 (has links)
[pt] O Modelo Média-Variância, proposto por Markowitz para resolver o problema de estruturação ótima de carteiras de investimentos, utiliza uma medida simétrica de risco, o desvio padrão dos retornos. Contudo, a grande utilização no mercado financeiro de ativos com retornos assimétricos levou ao desenvolvimento de medidas de risco assimétricas, como a semivariância e o downside risk, buscando quantificar de forma mais precisa a percepção de risco investidor. Neste trabalho, comparamos algumas metodologias para estruturar carteiras de investimentos contendo ativos com retornos assimétricos. / [en] The Mean-Variance model for asset allocation, proposed by Markowitz, use a symmetric risk measure, the standard deviation of returns. Although, because of the increasing use of financial instruments with asymmetric payoffs, asymmetric risk measures, as semivariance and downside risk, have been required in order to quantify the investor´s perception of risk as accurately as possible. So, we compare in this work several methodologies to structures optimal portfolios containing securities with asymmetric returns.
