The present study shows a demonstration of how the economic agent, in the stock market, makes certain decisions with non-rational tendencies, contrary to what is expected by the precepts of traditional economic theory. Thus, a critical systematic review of the theoretical production on the theme was elaborated, contrasting the theory with evidence observed in the stock market. Decisions verified in unique circumstances go against the procedure that agents would apparently need to adopt according to the principles of conventional economic theory. It was found that cognitive biases, in moments of decision-making under uncertainties and complex, can generate negative financial results. Of behavioral trends, the study highlights such: herd behavior, overconfidence, prospectus theory, anchorage, status quo, and possession effect. The study also points out ways to reduce or avoid the influence of cognitive biases on the behavior of agents during their decisions
