Question 283  portfolio risk, correlation, needs refinement

Three important classes of investable risky assets are:

• Corporate debt which has low total risk,
• Real estate which has medium total risk,
• Equity which has high total risk.

Assume that the correlation between total returns on:

• Corporate debt and real estate is 0.1,
• Corporate debt and equity is 0.1,
• Real estate and equity is 0.5.

You are considering investing all of your wealth in one or more of these asset classes. Which portfolio will give the lowest total risk? You are restricted from shorting any of these assets. Disregard returns and the risk-return trade-off, pretend that you are only concerned with minimising risk.

(a) Most money in corporate debt, with some money in equity and real estate.

(b) Most money in equity, with some money in corporate debt and real estate.

(c) Most money in real estate, with some money in corporate debt and equity.

(d) Most money in corporate debt, with some money in real estate and none in equity.

(e) All money in corporate debt.

Question 368  interest tax shield, CFFA

A method commonly seen in textbooks for calculating a levered firm's free cash flow (FFCF, or CFFA) is the following:

###\begin{aligned} FFCF &= (Rev - COGS - Depr - FC - IntExp)(1-t_c) + \\ &\space\space\space+ Depr - CapEx -\Delta NWC + IntExp(1-t_c) \\ \end{aligned}###

Does this annual FFCF or the annual interest tax shield?

Question 388  real option, option

A moped is a bicycle with pedals and a little motor that can be switched on to assist the rider. Mopeds are useful for quick transport using the motor, and for physical exercise when using the pedals unassisted. This offers the rider:

(a) An expansion option.

(b) An abandonment option.

(c) A timing (or delaying) option.

(d) A production (or switching) option.

(e) Lots of options to exercise if they're out-of-money and have no fuel.

Question 475  payout ratio, dividend, no explanation

The below screenshot of Commonwealth Bank of Australia's (CBA) details were taken from the Google Finance website on 7 Nov 2014. Some information has been deliberately blanked out.

What was CBA's approximate payout ratio over the 2014 financial year?

Note that the firm's interim and final dividends were $1.83 and $2.18 respectively over the 2014 financial year.

(a) 2.48%

(b) 4.85%

(c) 77.00%

(d) 129.93%

(e) 247.53%

Question 559  variance, standard deviation, covariance, correlation

Which of the following statements about standard statistical mathematics notation is NOT correct?

(a) The arithmetic average of variable X is represented by ##\bar{X}##.

(b) The standard deviation of variable X is represented by ##\sigma_X##.

(c) The variance of variable X is represented by ##\sigma_X^2##.

(d) The covariance between variables X and Y is represented by ##\sigma_{X,Y}^2##.

(e) The correlation between variables X and Y is represented by ##\rho_{X,Y}##.

Question 598  future, tailing the hedge, cross hedging

The standard deviation of monthly changes in the spot price of lamb is $0.015 per pound. The standard deviation of monthly changes in the futures price of live cattle is $0.012 per pound. The correlation between the spot price of lamb and the futures price of cattle is 0.4.

It is now January. A lamb producer is committed to selling 1,000,000 pounds of lamb in May. The spot price of live cattle is $0.30 per pound and the June futures price is $0.32 per pound. The spot price of lamb is $0.60 per pound.

The producer wants to use the June live cattle futures contracts to hedge his risk. Each futures contract is for the delivery of 50,000 pounds of cattle.

How many live cattle futures should the lamb farmer sell to hedge his risk? Round your answer to the nearest whole number of contracts.

(a) 9

(b) 10

(c) 19

(d) 23

(e) 47

Question 677  option, option profit, no explanation

Which of the below formulas gives the profit ##(\pi)## from being long a put option? Let the underlying asset price at maturity be ##S_T##, the exercise price be ##X_T## and the option price be ##f_{LP,0}##. Note that ##S_T##, ##X_T## and ##f_{LP,0}## are all positive numbers.

(a) ##\pi_{LP}=-max⁡(S_T-X_T,0) - f_{LP,0}##

(b) ##\pi_{LP}=-max⁡(X_T-S_T,0) + f_{LP,0}##

(c) ##\pi_{LP}=max⁡(S_T-X_T,0) - f_{LP,0}##

(d) ##\pi_{LP}=max⁡(X_T-S_T,0) + f_{LP,0}##

(e) ##\pi_{LP}=max(X_T-S_T,0) - f_{LP,0}##

Question 718  arithmetic and geometric averages

The symbol ##\text{GDR}_{0\rightarrow 1}## represents a stock's gross discrete return per annum over the first year. ##\text{GDR}_{0\rightarrow 1} = P_1/P_0##. The subscript indicates the time period that the return is mentioned over. So for example, ##\text{AAGDR}_{1 \rightarrow 3}## is the arithmetic average GDR measured over the two year period from years 1 to 3, but it is expressed as a per annum rate.

Which of the below statements about the arithmetic and geometric average GDR is NOT correct?

(a) Arithmetic average gross discrete return is ##\text{AAGDR}_{0\rightarrow T} = \dfrac{\text{GDR}_{0 \rightarrow 1}+\text{GDR}_{1\rightarrow 2}+...+\text{GDR}_{T-1 \rightarrow T}}{T}##

(b) Geometric average gross discrete return is ##\text{GAGDR}_{0\rightarrow T} = \dfrac{\text{GDR}_{0 \rightarrow 1} . \text{GDR}_{1\rightarrow 2} ... \text{GDR}_{T-1 \rightarrow T}}{T}##

(c) The geometric average gross discrete return can be quickly found using the first ##(P_0)## and last ##(P_T)## prices. ##\text{GAGDR}_{0\rightarrow T} = \left( \dfrac{P_T}{P_0} \right)^{1/T}##

(d) The arithmetic average is always bigger than or equal to the geometric average, ##\text{AAGDR} \ge \text{GAGDR}##.

(e) The arithmetic and geometric averages of returns will be equal if the variance of the stock's returns is zero.

Question 739  real and nominal returns and cash flows, inflation

There are a number of different formulas involving real and nominal returns and cash flows. Which one of the following formulas is NOT correct? All returns are effective annual rates. Note that the symbol ##\approx## means 'approximately equal to'.

(a) ##r_\text{real} \approx r_\text{nominal} - r_\text{inflation}##

(b) ##(1+r_\text{real})^t = \left( \dfrac{1+r_\text{nominal}}{1+r_\text{inflation}} \right)^t ##

(c) ##V_\text{t,real} = V_\text{t,nominal}.(1+r_\text{inflation})^t##

(d) ##V_\text{0} = \dfrac{V_\text{t,nominal}}{(1+r_\text{nominal})^t}##

(e) ##V_\text{0} = \dfrac{V_\text{t,real}}{(1+r_\text{real})^t}##

Question 845  accounting ratio, no explanation

Safe firms with low chances of bankruptcy will tend to have:

(a) Low current ratios.

(b) Low interest coverage ratios.

(c) High quick ratios.

(d) High debt-to-assets ratios.

(e) High amounts of leverage.
