Their results showed that the characteristic neuroticism is negatively related to risk taking in the domain of gains, but that the effect of neuroticism is reduced in the domain of losses.

The characteristic conscientiousness affected attitude to risk-taking. Intelligence was also a determinant of preference for more risky options. Countless phenomena can be associated with greater or lesser cognitive capacity, such as preference for risk, intertemporal preference, aversion to ambiguity, etc. According to [ 22 ], possible effects of cognitive abilities or cognitive traits are generally part of unexplained variance in studies that specifically analyze average behavior.

However, as shown by [ 23 ], intelligence, or specific cognitive abilities, are important determinants of decision-making and should not therefore be ignored. The Big Five model captures the majority of specific personality traits. In this paper we have operationalized intellect as a separate concept to openness to experience, which is one of the components of the Big Five. It is designed to assess the capacity to substitute an impulsive, and incorrect, response with reflection that leads to the correct response.

The requirements are intended to afford consumers with protection, since these products have terms, resources, and investment risks that may make them difficult to understand [ 26 ]. Each individual has a risk profile that determines their behavior in the face of investment under uncertainty conditions.

Thus, there are those risk-tolerant individuals who end up investing in more volatile assets and, on the other hand, there are individuals who refuse to expose themselves to risk, even with the possibility of higher returns. Such a description is easily verified in the different choices of each investor, but the determinants of this risk profile are still subject to investigation. One of the determinants of the individual risk profile that has been explored is the personality traits.

The results indicate that more risk tolerant individuals are more extroverted and intuitive. Likewise, [ 8 ] found that greater openness to new experiences triggers a greater predisposition to risk and [ 21 ] show that individuals with higher neuroticism have a lower predisposition to risk in the domain of losses. These evidences prove that there is a relation between the personality traits and the risk profile of the investors.

This is justified by the alteration that these personality traits can cause in the evaluation that each economic agent realizes of the conditions of uncertainty of the market [ 5 ]. However, even if there is evidence of this relationship it is still incipient, which does not allow the definition of a clear hypothesis of the expected relationships.

In this way, the hypothesis 1 is established more generally as follows:.

Behavioral Finance

H1: Personality traits are determinant to consolidate the risk profile of investors ;. In line with personality traits, cognitive ability can also be a determinant of investors' risk profile. People with greater cognitive ability tend to understand the financial market more consistently and thus are able to process information more easily which expands their participation in the stock market [ 28 ]. This is more likely, according to [ 22 ] and [ 29 ], that people with greater cognitive ability tend to have a riskier profile. Thus, the second research hypothesis is established as follows:.

H2: Individuals with greater cognitive ability present greater tolerance to risk;. Other variables that can determine investors' decisions in a risk environment are behavioral biases. Contrary to modern finance, behavioral finance understands that the choices of economic agents are not made on the basis of all available information and are not fully rational [ 3 ]. On the contrary, the errors of judgment and the cognitive biases resulting from these evaluations make the choices of economic agents to be made on the basis of a limited rationality [ 4 ].

Thus, according to [ 30 ], there is evidence that biases such as disposition effect, mental accounting, overconfidence, representativeness, restricted framework, aversion to ambiguity, anchoring, and availability bias distort the decisions of individual investors.

Overconfidence and myopia were also biases flagged in another study as important to signal investment choices [ 9 ]. All of these facts confirm that there may be a violation of rationality, and the third hypothesis of this study is stated as:. H3: The manifestation of investors' preferences is in accordance with the premises of prospect theory. Finally, moving away from the cognitive and behavioral aspects, this work also aims to evaluate if the questionnaires used by financial institutions are able to translate the real behavior of the economic agents.

This concern has proved to be relevant, since internationally it is already confirmed that the fact that the questionnaires do not incorporate the biases inherent in investment decision-making cannot reliably portray the real behavior of economic agents in the midst of their investments. Using the Risk Tolerance Questionnaire RTQ , [ 31 ] showed that respondents with more investment experience had more risk tolerance responses and higher risk portfolios than less experienced investors.

Thus, the last hypothesis of this research is presented:. This study employs the experimental method, a methodology that is relevant to the field of behavioral finance [ 32 ]. According to [ 33 ], experimental studies attempt to represent, in a simplified form, the collection of agents and institutions that make up the economy.

The experiment was conducted with undergraduate students from the economics and electrical engineering courses at the Federal University of Santa Catarina, during modules related to finance studies. A total of students took part. Thirty-four participants were women and were men. However, some of them were excluded from the study because of operational problems, leaving people, and the final study sample comprised the results from people, since participants who stated they already knew the answers to the CRT questionnaire were also excluded.

    The questionnaire was completed online at the same time by all respondents, during an experimental session. The questionnaire comprised 5 blocks of questions. The first covered aspects relative to investor profile. Next, there were 10 questions about investment scenarios, adapted from [ 4 ], to evaluate violation of the expected utility theory, and the results were used to create a dummy variable where 1 indicates that a participant predominantly at least 6 out of 10 questions were answered in a manner compatible with prospect theory behaved in accordance with prospect theory, while the value 0 indicates that the participant behaved in a manner compatible with expected utility theory.

    The third block was made up of 10 questions from the Big Five Inventory [ 34 ]. The CRT was administered separately from the other questionnaires and all participants started to answer it at the same time, because it has a time limit of 5 minutes.

    Once they had completed the questionnaire, all participants started the computational investment simulation at the same time. It was stressed that participation was voluntary and did not offer any type of material incentive to the participants. Only after the fulfillment of all the procedures and approval of the project has the research begun. Only those subjects who, after reading the term, agreed, in a free and clear way, to respond to the survey participated in the research. According to the Resolution, the Term of Consent guarantees, among other things, the clarification, before and during the course of the research, on the methodology used; the freedom to give up participating in the research, in any of the stages, without any kind of penalty or loss; indemnification against any damages resulting from the research; and the confidentiality of the disclosed data in order to maintain the privacy of the respondent.

    The assets used in the simulation were defined as those available as investment options through Bank of Brazil. Their results show that Bank of Brazil tops the ranking of institutions that manage investment funds in terms of assets invested in funds. Bank of Brazil investment funds were chosen with special attention to risk levels and for each risk level the fund chosen was that which had the largest net assets on the definition date, in this case, in May The data used for simulations are real financial data from the to Half-yearly closing data were used, for which the percentage change in the asset in the corresponding 6-month period was considered.

    Thus, for example, period 1 of the simulator corresponds to the percentage variation of the asset in the period from January to June , year 2 of the simulator corresponds to the percentage change from July to December Year 3 corresponds to the percentage change of January to June and so on. The participants were not informed what period in time the data were from, they were only told that the data were real historic data on the assets involved.
