Homework #5
Problem #1
An analyst developed the following probability distribution of the rate of return for a common stock:
Scenario Probability Rate of Return
1 0.20 0.18
2 0.35 0.22
3 0.45 0.26
Using the table above, find expected return, standard deviation and variance.
Problem #2
State of the World Probability (P) Return (R )
Expansion 0.15 15%
Normal 0.55 25%
Recession 0.30 35%
Using the table above, find expected return, standard deviation and variance.
Problem # 3
An investor holds the following portfolio which is invested in three stocks: Adidas, Victoria’s Secret and Nike.
Security Number of Shares Share Price Expected Return
Adidas 25,000 $ 20 8 %
Victoria’s Secret 10,000 $ 30 11%
Nike 30,000 $ 10 12%
Calculate the expected return for this portfolio.
Problem # 4
Which of the following portfolios has the best Sharpe ratio? What does this mean?
Portfolio Expected return Expected Standard
deviation
A 7% 14%
B 9% 25%
C 12% 23%
Risk Free 4% 0%
Problem # 5
Define risk aversion and discuss evidence that suggests that individuals are generally risk averse.
Problem #6
a) If your nominal return was 14.8% during the year and the inflation rate was 6.8%; what was your real rate of return. Calculate the exact and approximate answers.
b) If your nominal return was 7% during the year and the inflation rate was 3%; what was your real rate of return. Why is the difference between the approximate and exact answer smaller than in part a?
Problem #7
Bear Market Normal Market Bull Market
Probability 0.2 0.5 0.3
X -15% 20% 40%
Y -10% 15% 10%
Using the table above find:
a) Expected return for Stock X and Stock Y
b) Variance and StdDev of Stock X and Stock Y
Problem #8
If an investor has $50,000 to invest in the stocks X and Y (from problem #7) in proportions 55% and 45% respectively and additional $5000 in T-bills (R=3.44%), what is the expected rate of return for this portfolio?
