Trade-off risco-retorno
Abstract in Portuguese
A Teoria Moderna de Finanças, que se baseia nos princípios da aversão ao risco, da racionalidade dos agentes e na Hipótese dos Mercados Eficientes, postula que a relação risco-retorno dos ativos será positiva. No entanto, diante de estudos empíricos cujos resultados contradizem esses princípios, as Teorias de Finanças Comportamentais buscaram trazer explicações para as aparentes contradições. Nesse contexto, este trabalho analisa a relação risco-retorno no mercado brasileiro de ações. Os resultados reforçam a ideia de que investidores têm diferentes atitudes em relação ao risco dependendo do seu resultado passado, e esse é um fator potencialmente explicativo dos retornos futuros.

Abstract in English
The Modern Finance Theory, which is based on the principles of risk aversion, rationality of agents and the Efficient Markets Hypothesis, postulates that the risk-return relation of assets will be positive. However, in face of empirical studies whose results contradict these principles, the Behavioral Finance Theories sought to explain the apparent contradictions. In this context, this study analyzes the risk-return relation in the Brazilian stock market. The results reinforce the idea that investors have different attitudes towards risk depending on their past results, and this is a potentially explanatory factor for future returns.
