Question 1 [20 marks]
Question 1.1 (10 marks)
1.1.1 The return from the market last year was 10% per annum and the risk-free rate was 6% per
annum. A hedge fund manager with a beta of 1.1 has an alpha of 5%. Given the performance
of the market last year, what annual return did the hedge fund manager earn? (2)
1.1.2 The following information relates to a share in Lowveld Bank:
State of the economy Probability Annual Return
Expansion 0.45 16%
Sustained growth 0.25 10%
Recession 0.30 3%
a) Using the information provided, calculate the expected return, variance and standard
deviation of the share in Lowveld Bank. (5)
b) The expected return on the market portfolio is 9% per annum. Indicate whether Lowveld
Bank’s share has more, less or equal systematic risk and provide a reason for your answer.
(3)
Question 1.2 (10 marks)
1.2.1 An investment bank has been asked to underwrite an issue of 10 million shares by a
company. It is trying to decide between a firm commitment, where it buys the shares for $25
per share, and a best efforts arrangement, where it charges a fee of 30 cents for each share
sold. As part of the procedure to assess the risk, it considers two scenarios: firstly, where the
price that it can obtain per share is $30 and, secondly, where it can only receive a price of
$23 per share. Explain the difference between the two alternative arrangements. Show all
calculations. (5)
1.2.2 What is the function of a market maker in securities trading? Your answer should include the
function, together with the profits and risks involved. (3)
1.2.3 Explain the two net asset values (NAVs) of a close-ended mutual fund. (2)

Question 2 [35 marks]
Question 2.1 (8 marks)
2.1.1 You enter into a futures contract to sell white maize for R1 845 per tonne. The contract is for
the delivery of 1 000 tonnes. The initial margin is R200 000 and the maintenance margin is
R60 000. You receive a margin call of R140 000. What change in the futures price led to this
margin call? (Show all relevant calculations.) (3)
2.1.2 You enter into a short futures contract to sell 120 000 Swiss francs for US dollars at an
exchange rate of 1.13 US dollars per Swiss franc. Will you make a profit or a loss at the end
of the contract if the exchange rate goes up to 1.15? (Show all calculations.) (3)
2.1.3 Explain the difference between an American option and a European option. (2)
Question 2.2 (9 marks)
2.2.1 Suppose that the price of an asset at the close of trading yesterday was $350 and its volatility
was estimated as 1.4% per day. The price at the close of trading today is $347. The
proportional change in the price of the asset is -0.00857. What is the new volatility estimate
when using a GARCH(1,1) model with ω = 0.000003, α = 0.05 and β = 0.95? (4)
2.2.2 Suppose the parameters in a GARCH(1,1) model are α = 0.03, β = 0.93 and ω = 0.000005.
The current daily volatility is estimated to be 1.3%.
(a) What is the long-run average volatility? (3)
(b) Estimate the daily volatility in 20 days. (2)
Question 2.3 (9 marks)
2.3.1 Suppose that the current daily volatilities of asset A and asset B are 1.65% and 2.32%,
respectively. The prices of the assets at the close of trading yesterday were $35 and $52,
and the estimate of the coefficient of correlation between the returns on the two assets made
at that time was 0.26. The parameter λ used in the exponentially weighted moving average
(EWMA) model is 0.95.
(a) Calculate the current estimate of the covariance between the assets. (2)
