| Summary: | According to Prospect Theory, Investors have different behaviors in theprofit and loss situations and indeed their trading behavior is different in bulland bear markets. This study uses quantile regression model (in differentquartiles) and OLS model to estimate beta of 180 firms. Results showed thatfirst, equity total risk (standard deviation) increase in Upper quartile andsecond, stocks beta changes in different quartiles and by moving fromquartile 0.25 to quartile 0.75, systematic risk (beta) increases significantly.Linear regression model and Quantile regression model show also thatunexpected variance can explain excess return at least similar to expectedvariance. The results can also be interpreted with both Insight of standardfinance and insight of behavioral finance. In standard finance area, riskreturnpositive relation that exists in upper quintiles is consistent with longrun growth of economy. Moreover, negative relation between return and riskin lower quintiles imply more uncertainty and as a result causing stockreturns to fall. In behavioral finance area, regime-dependent behavior ofslope coefficients is consistent with prediction of Prospect theory ofinvestor’s behaviors around the reference point. |
