Question 1: Bond Valuation and Analysis
(20 points)
You are considering investing in a bond for the next twelve months. You are limiting your
choice of bond to one of the following, both of which pay annual coupons at year end and
have identical credit risk:
(a)
(b)
(c)
(d)
Bond
Maturity
Coupon
YTM
A
2 years
8%
7.842%
B
3 years
9%
8.027%
If the one year, two year and three year spot rates are 7.65%, 7.85% and 8.05%
respectively, determine the prices of bond A and bond B.
Estimate, using duration, the expected change in price of bond B for a 0.2% change
in yield to maturity.
Calculate the difference in the one year holding period return on the bonds, assuming
that spot rates will fall in twelve months’ time by 0.2% across the maturity spectrum.
When estimating holding period return, what are the implications of each of the
following assumptions?
(i)
the yield to maturity or spot rate curve will remain constant; and
(ii) the forward rate curve correctly estimates future spot rates

Question 2: Bond Valuation and Analysis
(25 points)
A pension fund is currently showing a surplus in its asset/liability position (see table below).
Under International Accounting Standards (IAS), which were recently adopted, pension
liabilities must be valued at market interest rates, and, if they are larger than fund assets, the
difference must be posted to the corporate balance sheet as a liability. You have been asked
to invest in bonds in such a way as to avoid this happening. Answer the following questions
about your investment strategy.

Assume that the amount of future pension benefits is fixed in nominal terms and that
you want to maintain a surplus even if there is a movement in interest rates that
causes a change in the liability. You may also assume for the following questions that
interest-rate movement is parallel and that the convexity effect can be ignored.
(i)
If you keep your current asset mix, how many percentage points up or down
will interest rates need to move before the surplus is negative?
(ii) You want to keep the current asset mix ($80 million in bonds, $40 million in
equities), but change the composition of the bond portion so that the current
surplus is maintained even if interest rates move. How many years should the
bonds’ modified duration be?
(iii) If you put all of your assets into bonds, what modified duration will enable you
to maintain the current surplus even if interest rates move?
(iv) Referring to the previous two cases, i.e. (a)(ii) and (a)(iii), discuss the pros and
cons of lengthening the duration of your bond investments.
Pension benefit amounts will be usually indexed to inflation, and you need to take
this factor into account in valuing pension liabilities and in managing bond
portfolios.
(i)
Assume the kind of investments described in Question (a)(iii). If there is
inflation, what effect will it have on assets and liabilities and on the surplus?
(ii) If pension benefit amounts are indexed to inflation, what discount rate should
you use to value liabilities?
(iii) Discuss the kind of bonds you should invest in if pension benefit amounts are
indexed to inflation.

Question 3: Derivative Valuation and Analysis
(25 points)
You are currently managing a well-diversified stock portfolio with a beta of 1.2 on the
TOPIX* index of Tokyo Stock Exchange stock prices. The TOPIX is now at 1600, oneyear (riskless) interest is 3%, and the aggregate market value of your portfolio is ¥16 billion.
Ignoring dividends, answer the following questions. (Where calculations are necessary,
include the calculations clearly in your answer sheet.)
*TOPIX: The weighted average stock price index of all TSE 1st Section listed stocks.
(a)
(b)
Given a TOPIX value of T one year from now, what will be the Value V of your
portfolio at this time? Express V as a function of T.
(i)
Assume the prices and deltas of a put option on the TOPIX with one year to
maturity are as follows:
Exercise Price
1600
1608
1616
1624
1632

–0.406
–0.419
–0.431
–0.444
–0.457
–0.470
Delta
(c)
Depending on the TOPIX value one year hence, your portfolio may suffer a
loss and you have thought of hedging with a purchase of puts capable of
maintaining the minimum portfolio value (before put premium, of ¥16
billion). Assuming that one TOPIX option corresponds to an amount 10,000
times that of the index, how many puts should you buy at what exercise price?
(ii) How much will this hedge cost?
Since it is difficult to buy puts with one year to maturity on the market, you think of
achieving the same results as in Question 2 by using futures for dynamic hedging.
(i)
Assuming that one-month (risk-free) interest is now 3% (at an annual rate) and
that the TOPIX futures with one month to maturity are at their theoretical
price, how many futures should you sell for the purpose of dynamic hedging?
Assume that the trading unit of the TOPIX futures is 10,000 times the index
and that the amount corresponding to the costs required for the puts purchased
in Question 2 is invested at the risk-free interest rate.
(ii) Assume that immediately afterwards, stock prices rise and TOPIX hits 1632.
Now how many futures should you sell in order to effect dynamic hedging?
The prices and deltas of a put with one year to maturity when TOPIX is at
1632 are as follows:
(iii) The put prices and deltas given in the table for Question (c)(ii) above are the
figures given an estimated volatility of 15%. Explain what the results of
dynamic hedging would be if volatility were actually greater than 15% and
TOPIX fell.

Question 4: Derivative Valuation
(35 points)
The date is 20 April. You are a stockbroker at a large Australian firm and specialise in
dealing in derivative markets. As part of your daily routine, you discuss a range of
opportunities and strategies with clients.
(a) You take a call from an investor who has decided to set up a buy/write fund, which is
not allowed to gear/lever. Her strategy is to buy and always hold BHP shares and
write options against the holding. She also states that the fund will earn over 20% per
annum over the next year with no risk of loss.
(i)
What type of option trades would the investor seek to enter into, given that she
is already holding BHP shares? Buy/sell, puts/calls or both? Justify your answer.
(ii) Discuss the investor’s comment as to ‘no risk of loss’ with reference to what
assumptions would be required to make this statement true and what will
generate the return from the strategy.
(iii) Outline a strategy that would give a similar result to that outlined above but
using different types of options and underlying security.
(b) Your next call is from the Head of Asset Allocation at a fund manager. She tells you
that they expect the equity market to be extremely volatile over the next three
months and that she thinks there is an equal chance of either a 15% rise or fall over
the period.
(i)
Using the following data, suggest an option strategy that would suit the
manager’s view. Draw a payoff diagram that will graphically demonstrate the
outcome of the strategy at maturity for various levels of the All Ordinaries
Index1 (include break-even points and maximum profit/loss).

1. The All Ordinaries Share Price Index (SPI) also referred as the “All Ordinaries” is the predominate measure
of the overall performance of the Australian sharemarket at any point in time. It is made up of shares of
approximately 250 of the largest Australian companies on ASX, weighted according to each company’s size in
term of market capitalization.

high, which is at odds with your view that the share price will stay at the same
level over the next three months. Suggest a course of action (along with
reasons) to the trader that would hedge the portfolio to unexpected price
moves in Newscorp over the period of absence. Use only the type of securities
currently represented in the portfolio.

Question 5: Portfolio Management
(33 points)
You are a consultant to a big institutional client. He shows you the brochure of a product
with the title “Invest your money in stocks but sleep well!” which he has got from his bank.
The product has the following characteristics:
maturity:
1 – 3 years
payoff at maturity date:
C, if Imd < Isd
 I −I

C × 1 + md sd × P1 , if Imd ≥ Isd
Isd


where:
C
= invested capital (in USD), minimum: 10 Mio. USD
Isd
= Index level at starting date
Imd = Index level at maturity date
Index = S&P500
P 1 = positive number, determined at starting date
The client can chose the maturity according to his preferences and the parameter P1 is
determined by the bank.
(a) Explain to your client the characteristics of this product. Sketch the payoff diagram
indicating every level and slope. Describe to your client how the portfolio manager
could implement this strategy. Illustrate your description with the special case where
the manager should not use any stocks or future, under the assumption that all other
necessary assets are available.
(b) The client wants to know the meaning of the parameter P1 and which market
parameters or other parameters determine its value. Explain this to him in detail.
The bank also offers another product with the following payoff:

Explain to your client the characteristics of this product and how they differ from
those of the first product. Sketch the payoff diagram indicating every meaningful
level and slope. Describe how the portfolio manager could implement this strategy.
What can you say about the parameters P1 and P2 in both the products
(qualitatively)? Do you expect them to be equal or not? If yes, explain why: if not,
indicate which of the two you expect to be higher and why.
Does the level of Imax have any impact on P2? Justify your answer.

The alpha (α) column in the table indicates the expected “excess return” of the fund
(i.e. the return earned by the fund minus the benchmark return); σ indicates the standard
deviation of excess return; and “IR” is an abbreviation for “Information Ratio”, which is
defined as
α/σ.
The formulas below give the theoretical allocation to each manager, assuming that there is
no correlation between the excess return and benchmark return for any of the funds and
that excess returns of individual funds are mutually independent.
• Allocation to active manager:
• Allocation to passive manager:
i xi =
τIR i
2σ i
P x p = 1 − ∑ ix i
Note that τ is a parameter indicating the degree of risk tolerance given for each investor.
Answer the following questions with reference to the information above.
Pension Fund Z thinks that the stock market has been fairly efficient so far. It had
previously decided on a 0.5 allocation to the passive component, but has reviewed its policy
and now wishes to change its allocations between active and passive managers based on the
theoretical formulas shown above.
(a) It is often said that the passive investment component should be increased the more
efficient the market is. Why is this so? Explain by using the theoretical formulas
above.
(b) Pension Fund Z’s degree of risk tolerance τ is estimated at 20. Find the optimal
allocation ratios for each fund, assuming the excess returns of individual active funds
to be mutually independent.
(c) The actual correlation between the excess returns of A and B was positive since they
had similar investment styles. How would this change optimum allocation ratios to
individual managers (A, B, C, and P) from what they were in (b) above?
(d) The a and s for each fund are estimated based on past performance, but there may be
some problems raising allocation ratios based on these numbers. Explain why that is.

Question 7: Portfolio Management
(8 points)
As a portfolio manager you decide to answer a request for a proposal by a pension fund. Its
committee, responsible for the asset allocation, needs passive management relative to the
following benchmark:
• 50 % SMI (Swiss Market Index / 23 stocks)
• 50 % MSCI Europe ex Switzerland (multi-country Index / 524 stocks / 21 countries)
Assume that the pension fund portfolio will be measured against its benchmark on a
monthly basis. What is the main problem you will face when indexing this portfolio in the
long run? What potential negative impact do you expect and what positive effects, if any,
could you exploit?

with the returns of the other 4 portfolios?
One of your competitors uses the CAPM. Based on the betas above, which portfolio
will he choose to maximise his expected return?
In order to diversify his perceived risk, another competitor wants to combine the
Small Value and the Large Growth Portfolios. The new portfolio should have an
overall sensitivity to Factor I (market beta) of 1. Show how much the competitor
must invest in Small Value and how much in Large Growth. The portfolio must be
fully invested and without any short sale.
