Dylan's portfolio consists of three stocks: TSLA, 30%, beta 0.55; BAC, 30%, beta 1.45; and Costco, 40%, beta 0.94. Compute Dylan’s portfolio beta.
A |
0.98 |
|
B |
1.22 |
|
C |
1.13 |
|
D |
0.85 |
Answer: Option A is correct.
Portfolio beta is calculated as:
Portfolio beta=(% of TSLA in the portfolio)*(Beta of TSLA)+(% of
BAC in the portfolio)*(Beta of BAC)+(% of Costco in the
portfolio)*(Beta of Costco)
Given that:
Percentage of TSLA in the portfolio=30%
Beta of TSLA=0.55
Percentage of BAC in the portfolio=30%
Beta of BAC=1.45
Percentage of Costco in the portfolio=40%
Beta of Costco=0.94
Substituting these values in the equation we get:
Portfolio beta=30%*0.55+30%*1.45+40%*0.94
=0.165+0.435+0.376
=0.976 or 0.98 (Rounded to two decimal places)
