Part II: Longer Answers
1. (26 points) On January 1, you sold short one round lot (i.e. 100 shares) of Zenith stock at $40
per share. The initial margin requirement was 50% and the maintenance margin is 30%. The
margin account pays no interest. On March 1, Zenith paid a dividend of $2 per share. On
April 1, the share price rises suddenly to $45 at the opening of trading.
a) (5 points) List all assets and liabilities. What is the remaining margin (equity) in the
account on April 1 (in dollars)?
EquityJanuary = Initial %margin x sale proceeds = 50% x $4,000 = $2,000 = Initial margin

6,000 Total liabilities and equity
EquityApril = 4,000 + 2,000– 4,500 – 200 = 1,300
b) (6 points) What is the percentage margin? Do you receive a margin call?
Percentage margin = Equity/Value of shares owed = 1,300/4,500 = 28.9%
Yes, I receive a margin call from the broker.
c) (5 points) What is the minimum price for the broker to issue a margin call?
Equity
6000 − 100P − 200
=
Value of shares owed
100P
P = 44.62
30% =
If the price rises to $44.62 or more, the broker issues a margin call.
d) (5 points) If you cover the short sale on April 1 after the price increase, what is your rate
of return (HPR)?
HPR = (EquityApril-EquityJanuary)/EquityJanuary = (1,300 – 2,000)/2000= -35%
e) (5 points) What is your EAR?
EAR = (1-35%)4-1 = -82%
2. (10 points) You have just purchased a corporate bond that has a coupon rate of 10% and a
maturity of 4 years. The yield to maturity on the bond is 8%.
a) (2 points) What is the current price of the bond?

b) (3 points) If interest rates increase from 8% to 8.2% one year from now and coupons are
not reinvested, what would be the 1-year holding period rate of return on the bond?
P1 =

HPR = Coupon Payment + Capital Gains = 100 + (1,047.03 – 1,067.33) = 7.47%
Initial Bond Price
1,067.33
c) (3 points) If yields stay at 8.2% for the remaining 3 years and coupons are reinvested,
what is the effective annual return on this bond over the 4-year period?

HPR = 1,462.29/1067.33 -1 = 37.01%
EAR = 1.37011/4-1 = 8.19%
d) (2 points) A different bond has a coupon rate of 7%, one year to maturity, and its price is
quoted as 100.19. What is its yield to maturity?
We need to find the period rate r that solves 1,001.90 = 35/1+r + 1035/(1+r)2
We can use trial and error, or use the quadratic formula for x2 + ax + b =0
Let x = (1+r) óx2 - 35/1,001.9 x- 1035/1,001.9=0
x=-a/2 ±(a2/4 -b)0.5 = 1.747% ± 1.01653 = 1.03400 = 1+r
r=3.4% => YTM = 6.8%
3. (15 points) Assume that the S&P 500 tracks only the following 3 stocks. Stock B just had an

a) (5 points) What is the index return from Feb. 8 to Feb. 9?
Index level on Feb. 8 = (60 * 10 + 80 * 20 + 30 * 50)/(10+20+50) = 46.25
Index level on Feb. 9 = (52 * 10 + 70 * 30 + 31 * 50)/(10+30+50) = 46.33
HPR = 46.33/46.25 -1 = 0.173%
b) (5 points) What's the EAR?
EAR = (1+0.173%)365-1 = 87.91%
c) (5 points) If inflation were 1% per month, what would be the real annualized return?
EAR = 1.0112-1 = 12.68%
Fisher equation: real rate = 1.8791/1.1268 -1 = 66.7%

a. (5 points) Calculate the HPRs
HPR = Closet/Closet-1 -1 (see table)
b. (5 points) What are the arithmetic average and geometric average rates of return?
ra = 3.32%
1280.08 (1+rg)5= 1271.87
rg=(1271.87/1280.08)1/5-1 = -0.13%
rg is also called the CAGR (Compound Annual Growth Rate) in this context
c. (5 points) What is the standard deviation of returns?
SD = (sum of squared deviation / n-1)1/2 = (0.296377 / 4)0.5 = 27.22%
d. (5 points) If the past is a good guide to the future, what level do you expect the index
to reach on 1/3/2012 and on 1/3/2021?
E(Index)1/3/2012= 1271.87 * (1+ra) = 1,314
E(Index)1/3/2021= 1271.87 * (1+rg)10 = 1,256
