Abstract
Our article analyzes the performance of different methods to adjust beta. Specifically, we compare the standard ordinary least squares (OLS) regression method with the Blume and t-distribution methods from the point of view of reference-day risk. Our results indicate that the t-distribution method minimizes the variation due to changes in the reference day.
