expected returns on these stocks are 12 percent and 18 percent, respectively.
Required:
What is the expected return on the portfolio?
(Do not include the percent sign (%). Round your answer to 2
decimal places (e.g., 32.16).)
Expected return on the portfolio
%
Explanation:
The expected return of a portfolio is the sum of the weight of each asset times the expected return of each asset. The
total value of the portfolio is:
Total value = $2,700 + 3,800
Total value = $6,500
So, the expected return of this portfolio is:
E(R
p
) = ($2,700/$6,500)(0.12) + ($3,800/$6,500)(0.18)
E(R
p
) = 0.1551 or 15.51%

Explanation:
1:
The expected return of an asset is the sum of the probability of each return occurring times the probability of that
return occurring. So, the expected return of each stock asset is:
E(R
A
) = 0.24(0.030) + 0.59(0.110) + 0.17(0.28)
E(R
A
) = 0.1197 or 11.97%
E(R
B
) = 0.24(–0.39) + 0.59(0.29) + 0.17(0.52)
E(R
B
) = 0.1659 or 16.59%
2:
To calculate the standard deviation, we first need to calculate the variance. To find the variance, we find the squared
deviations from the expected return. We then multiply each possible squared deviation by its probability, and then
sum. The result is the variance. So, the variance and standard deviation of each stock is:
σ
A
2
=0.24(0.030 – 0.1197)

+ 0.59(0.110 – 0.1197)
