Answer :

Parrain

Answer: 1.50

Explanation:

Isabel's portfolio beta is a weighted average of the individual stock betas.

= Weight of stock A * Stock A beta +  Weight of stock B * Stock B beta +  Weight of stock n * Stock n beta

= (20% * 0.4) + (30% * 1.2) + ( 25% * 2.5) + (25% * 1.75)

= 0.08 + 0.36 + 0.625 + 0.4375

= 1.5025

= 1.50
