Question

You own a stock portfolio invested 25 percent in Stock Q, 25 percent in Stock R, 15 percent in Stock S, and 35 percent in Stock T. The betas for these four stocks are 1.28, 0.45, 1.78, and 1.22, respectively. What is the portfolio beta?

Answer 1

1.1265

Step-by-step explanation:

The computation of the portfolio beta is shown below:

= Stock Q portfolio percentage × beta of Stock Q + Stock R portfolio percentage × beta of Stock R + Stock S portfolio percentage × beta of Stock S + Stock T portfolio percentage × beta of Stock Q

= 0.25 × 1.28 + 0.25 × 0.45 + 0.15 × 1.78 + 0.35 × 1.22

= 0.32 + 0.1125 + 0.267 + 0.427

= 1.1265
