Answer:
Given: Investment in Stock A = $6000 and in Stock B = $4000
Particulars weights beta
Stock A 60 percent 0.85
Stock B 40 percent 1.6
The following is the calculation of the portfolio beta
Portfolio Beta = (0.6 multiply with 0.85) + (0.4 multiply with 1.6)
Solving the equation:
= 0.51 + 0.64
Thus, after solving we get, 1.15
Thus, the portfolio beta = 1.15
Based on the portfolio beta being a weighted average of individual betas, the portfolio beta here is 1.15.
As mentioned, the portfolio beta is a weighted average of the betas of the individual stocks.
It is therefore calculated as:
= (Weight of stock A x Beta of stock A) + (Weight of stock B x Beta of stock B)
Solving gives:
= ( 6,000 / (6,000 + 4,000) x 0.85) + (4,000 / (6,000 + 4,000) x 1.6)
= 0.51 + 0.64
= 1.15
In conclusion, the portfolio beta is 1.15.
