1.1 Calculate the price-weighted index of the three stocks for each period (4 points). What is the divisor for each period (4 points)? Does it
change in the last period (2 points)? Why or why not (2 points)?

1.2 Calculate the price-weighted index returns for the periods ending in 1 and 2 (7 points).

1.3 Calculate the value-weighted index returns for the periods ending in 1 and 2 (7 points).

1.4 Calculate the equal-weighted index return for the period ending in 1 (7 points).

Problem 2 Margin (34 Points)

2.A. The current market price for XYZ is $130 per share. Initial margin is 50% maintenance margin is 35% and margin interest is 1.25% per
year.

2.A.1) You believe the stock price will increase over the next year and wish to trade exactly one round lot. What trade should you make (2
points)? How much margin would you have to post to your account (4 points)? At what price would you receive a margin call (7 points)?

2.A.2) Suppose you are correct and the stock rises to $147 per share at the end of the year. What is your percentage return on equity for this
trade (4 points)?

2.B. The current market price for ABC is $90 per share. Initial margin is 50% maintenance margin is 35% and there is no margin
interest.

2.B.1) You believe the stock price will decrease over the next year and wish to trade exactly one round lot. What trade should you make (2
points)? How much margin would you have to post to your account (4 points)? At what price would you receive a margin call (7 points)?

2.B.2) Suppose you are correct and the stock falls to $74 per share at the end of the year. What is your percentage return on equity for this
trade (4 points)?

3.a) What are the expected rates of return for stocks X and Y (11 points)?

3.b) What are the standard deviations for of returns for stocks X and Y (11 points)?

3.c) Assume you have a $100000 portfolio and you invest $45000 in stock X and the remainder in stock Y. What is the expected return for
this portfolio (11 points)?
