4. The last stock added to this portfolio was Lauren Clothin, which has a beta of 0.30. What was the portfolios beta before Laurens stock was added?

Explanation / Answer

Hi,


Please find the answer as follows:


Part A:


9.4 = 5 + B*(4)


Portfolio Beta = (9.4 - 5)/4 = 1.1



Part B:


Portfolio's Beta before Addition = X


1.1 = .80X + .20*.30


X = (1.1 - .06)/.80 = 1.3


Portfolio's Beta before Addition would be 1.3.


Thanks.
