Behavioral Finance exists already some time, but only in recent years has its studies become more widespread. Its premises diverge from the assumption of rationality of decision-makers adopted by Traditional Finance. The concept of loss aversion is considered one of the pillars of Behavioral Finance and says that investors consider both the investor s earnings as well as the losses, but do not give them the same psychological value. Thus, in recent years, interest has grown between investment managers and researchers in understanding the investor’s risk behavior, which means the same as knowing whether investor is tolerant or not to risk. Through the application of a questionnaire that included questions related to demographic characteristics, the psychological profile and the level of risk tolerance, it was possible to identify some interesting and useful relationships between these variables with the degree of risk tolerance, the dependent variable. In possession of this information, financial agents can better focus on investment in accordance with the perceived profile of their customers.
