Abstract :
. The present study presents a model for mass behavior (derived from behavioral biases) in the decision-making of investors in investment companies on the Tehran Stock Exchange. Gathering information about the factors affecting mass behaviors, experts in this field were consulted and also these behavioral biases were scored. The statistical population of the present study is primarily the qualitative phase, including experts of the Tehran Stock Exchange. Eleven experts collaborated with the researcher in conducting specialized interviews. Then, by creating researcher-made questionnaires among 200 managers of distribution companies and the results obtained, the variables are a 6-category model, which in all cases has a factor greater than 0.6, which shows the correlation between hidden variables and observable variables. It is very strong and the value of t-value for all items is greater than 1.96, which shows that the observed correlations between items and structures are significant and the average variance extracted in all cases is greater than 0.5. In this research, normal chi-square is obtained 1.85. The RMSEA index is 0.034 and the SRMR is 0.035, which indicates that the model fits is desirable, of the whole and the significance of each of the final research model coefficients with 33 indices and six main categories, which include Self-control, perceptual error, social interactions, decision-making results were extracted from economic and judgmental perspectives
