Summary: The classical economic theory assumes that people make decisions through rational processes, particularly in the sense that they are coherent and consistent. However, many experimental studies indicate violations of this assumption. Two factors that lead to these violations are Overconfidence and Aversion to extremes, this is the preference of intermediate choices, avoiding extreme options. These factors commonly induce investors to make decisions that generate further frustration. The financial crisis of 2008, WHERE there was a large depreciation of various assets, also showed that many people chose not coherent with their investment profile. So in 2010, the Brazilian Association of Financial and Capital Markets (ANBIMA) determined that the institutions that sell mutual funds must make an evaluation Investor Profile (API) so that investors are advised to make investments consistent with your profile. This study aimed to verify the score resulting from the API and the Degree of Confidence in investment decisions make people more susceptible to the effect Aversion Extremes. To fulfill this objective, a questionnaire was administered to 112 undergraduates courses in Administration, Accounting and Economics from the Federal University of Espírito Santo. Based on the theoretical framework were outlined eight chances. The first hypothesis aims to Analysis of Investor Profile and Degree of Confidence in investment decisions make people more susceptible to the effect Aversion Extremes. The other hypotheses identify the relationships between gender, degree of confidence, the API and Investment Decisions. Additionally, characteristics of which were verified Investor Profile make individuals more likely to effect Aversion Extremes. The main conclusion of this study is the first hypothesis, whose tests reveal that the higher the API more likely occur in the end, while the Degree of Confidence in Investment Decisions not increase susceptibility to extreme aversion.
