Assignment 2 Instructions Assignment 2 should be submitted after you have completed Unit 3. This assignment is worth 15 percent of your final grade. Assignment 2 contains four problems. The maximum mark for each problem is noted at the beginning of the problem. This assignment has a total of 100 marks. Read the requirements for each problem and plan your responses carefully. Although your responses should be concise, ensure that you answer each of the required components as completely as possible. If supporting calculations are required, present them in good form. When you receive your graded assignment, carefully review the comments the marker has made. This review component is an important step in your learning process. If you have any questions or concerns about the evaluation, please contact the Student Support Centre. Problem 1 (15 marks) Suppose the return on portfolio P has the following probability distribution: Probability Return on P Bear Market 0.2 -20% Normal market 0.5 18% Bull market 0.3 50% Assume that the risk-free rate is 9%, and the expected return and standard deviation on the market portfolio M is 0.19 and 0.20, respectively. The correlation coefficient between portfolio P and the market portfolio M is 0.6. Answer the following questions: 1. Is P efficient? 2. What is the beta of portfolio P? 3. What is the alpha of portfolio P? Is P overpriced or underpriced? Problem 2 (20 marks) Consider a two factor economy. Assume the risk-free rate = 3%, and the risk premiums are RP1 = 10%, RP2 = 8%.

Assignment 2
Instructions
Assignment 2 should be submitted after you have completed Unit 3. This assignment is
worth
15 percent of your final grade.
Assignment 2 contains four problems. The maximum mark for each problem is noted at
the beginning of the problem. This assignment has a total of 100 marks.
Read the requirements for each problem and plan your responses carefully. Although
your responses should be concise, ensure that you answer each of the required
components as completely as possible. If supporting calculations are required, present
them in good form.
When you receive your graded assignment, carefully review the comments the marker
has made. This review component is an important step in your learning process. If you
have any questions or concerns about the evaluation, please contact the Student
Support Centre.

Problem 1 (15 marks)
Suppose the return on portfolio P has the following probability distribution:
Probability
Return on P

Bear Market
0.2
-20%

Normal market
0.5
18%

Bull market
0.3
50%

Assume that the risk-free rate is 9%, and the expected return and standard deviation on
the market portfolio M is 0.19 and 0.20, respectively. The correlation coefficient between
portfolio P and the market portfolio M is 0.6.
Answer the following questions:
1. Is P efficient?
2. What is the beta of portfolio P?
3. What is the alpha of portfolio P? Is P overpriced or underpriced?

Problem 2 (20 marks)
Consider a two factor economy. Assume the risk-free rate = 3%, and the risk premiums
are
RP1 = 10%, RP2 = 8%. The return on stock ABC is generated according to the following
equation:
rABC=0.08-0.55F1+1.2F2+eABC
Assume that the stock is currently priced at $50 per share.
1. What is the expected return for stock ABC using the APT?
2. Is stock ABC underpriced or overvalued?
3. If the expected price next year will be $55, what is the stock price now that will
not allow for arbitrage profits?
4. Assume that the risk free rate increases to 4%, with the other variables remaining
unchanged. Would you recommend to buy or sell stock ABC?

Problem 3 (15 marks)
Suppose that the index model for two Canadian stocks HD and ML is estimated with the
following results:
RHD =0.02+0.80RM+eHD
R-squared =0.6
RML =-0.03+1.50RM+eML
R-squared =0.4
?M =0.20
where M is S&P/TSX Comp Index, RX is the excess return of stock X.

3. Using the Tools menu in EXCEL, (Tool Pack has to be installed if EXCEL does
not show it) perform regression analyses using the Market Model for BNS.
4. Clearly provide the regression results in a table with an explanation for the
coefficients obtained, and clear interpretation. Specifically, for each regression
provide:
?
? Independent Variable
? Intercept
? Dependent Variable

Beta Value

? Firm Specific Risk

i.

ii.

What is the alpha of the BNS stock?

iii.
