  1. t statistics in parentheses: *p < 0.05, **p < 0.01, ***p < 0.001.
  2. Note: Alphas are calculated for each group of analysts, i.e., stars and non-stars, as an intercept from the regression. As an additional test, the table includes alphas for the Star-1 category, those Star analysts who are ranked “number one”. The right side of the table shows the difference in alphas between each group of analysts. The long-short portfolio suggests that stars, on average, have higher alphas compared to non-stars. “Number one”-ranked stars show overperformance in all portfolios.
