Note(s): We adopted an overlapping method with a 12-month estimation period and a rolling frequency of 1 month to obtain monthly loadings. Specifically, during the initial 12-month sample period, we perform time-series monthly regressions following the model outlined in equation (1) to derive the cross-section of βTMBO. This process was repeated for the subsequent 12-month period until the end of the sample period. Consequently, we obtained monthly βTMBO values for each stock. These estimated βTMBO values are then employed to classify stocks into quintile portfolios, and the value-weighted averages of these βTMBO values are presented in the column labeled pre-ranking βTMBO. The portfolios are reclassified on a monthly basis. Once the portfolios are formed, we calculate the value-weighted average excess and abnormal returns for each quintile portfolio one month after the formation date. We computed the time-series averages for each portfolio. Additionally, we estimate the loadings on the left-tail factor during the same period to calculate the average excess returns, aiming to explore any contemporaneous patterns between them. The post-ranking βTMBO for the entire sample was estimated by conducting time-series monthly regressions of the post-ranking portfolio returns on the left-tail factor. The t-statistics are shown in parentheses. ***, ** and * indicate the 1%, 5% and 10% statistical significance, respectively
