Adjusted Beta Β = α 0 +α 1 Β i,t-1. Where, α 0 + α 1 = 1. Because of the mean reverting property of beta, the adjusted beta will move closer to 1. If the historical or unadjusted beta is greater than 1, then the adjusted beta will be lesser that unadjusted beta and closer to 1, and vice versa. Let's take an example to understand this. First. beta is a sensitivity to a (particular) systematic market risk.
