You are composing a two-stock portfolio consisting of 20 percent Stock A and 80 percent Stock B. Given the following information, find the standard deviation of this portfolio.
Company | Beta | Expected Return | Standard Deviation | Covariance |
---|---|---|---|---|
A | 1.5 | 28% | 50% | COVA,B = 0.06 |
B | 2.2 | 12% | 40% |
Round to the nearset hundredth percent. Answer in the percent format. Do not include % sign in your answer (i.e. If your answer is 4.33%, type 4.33 without a % sign at the end.)
SDa = 0.50
SDb = 0.40
Wa= 20%
Wb = 80%
Cov (a,b) = 0.06
Correlation (R(a,b)) = Cov (a,b) / (SDa * SDb)
= 0.06 / (0.50 * 0.40)
= 0.3
SD of Portfolio =

=
= 36.28% OR 0.36276714294
