The empirical results suggest that the data generating process of Iran stock returns series is nonlinear Smooth Transition Autoregressive (STAR) and dynamic adjustment of the stock returns to the long run equilibrium level is asymmetric. The adjustment mechanism of the Iran stock returns deviations from the equilibrium level are different in the bull and bear markets.</p><p><strong>Keywords: </strong>Stock returns; Smooth transition; Bull and bear markets</p><p><strong>JEL Classifications:</strong><strong>&nbsp;</strong>G12; G14; G15; C22</p> ER -
