RESUMO

Behavioral finance researches indicate that individual financial decisions are not made based on a completely rational context. This assumption disagrees from the classical economic models that believe in a rational financial agent, which takes its decisions according to the utility curve to maximize its wealth. Behavioral finance incorporates psychology and sociology to better understand the individual process of decision. Different studies done in this field of research became evident that these kinds of decision are built up by agents that have excessively optimism, high self-confidence, aversion to losses and other aspects that are deep-rooted in our culture. Huge demographic changes in the past few years, specially the increase in life expectancy, impacted the pension plan structures. The main global trend to address these changes has been the movement to migrate from the defined benefit saving plans to defined contribution saving plans. As a result of this trend, we can observe an increase in the participants` responsibilities, with emphasis to the decision about the asset allocation. The objective of this research is to analyze the behavioral aspects of the individuals related to the task of asset allocation. The occurrence of a naïve diversification of investments in defined contribution saving plans can hardly affect the individual retirement. To verify this assumption, four different questionnaires were sent to different groups of individuals. Post Tests were ran to evince the occurrence of a naïve diversification of investments, as well as the use of 1/n strategy - divide savings in similar parts according to the amount of available options of investments.
