Question 65  annuity with growth, needs refinement

Which of the below formulas gives the present value of an annuity with growth?

(a) ##\dfrac{C_1}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

(b) ##\dfrac{C_1(1+g)^T}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

(c) ##\dfrac{C_1}{r-g}\left(1-\dfrac{1+g}{(1+r)^T}\right)##

(d) ##\dfrac{C_1}{r-g}\left(1-\left(\dfrac{1+g}{1+r}\right)^T \right)##

(e) ##\dfrac{C_1(1+g)}{r-g}\left(1-\dfrac{1}{(1+r)^T}\right)##

Hint: The equation of a perpetuity without growth is: ###V_\text{0, perp without growth} = \frac{C_\text{1}}{r}###

The formula for the present value of an annuity without growth is derived from the formula for a perpetuity without growth.

The idea is than an annuity with T payments from t=1 to T inclusive is equivalent to a perpetuity starting at t=1 with fixed positive cash flows, plus a perpetuity starting T periods later (t=T+1) with fixed negative cash flows. The positive and negative cash flows after time period T cancel each other out, leaving the positive cash flows between t=1 to T, which is the annuity.

###\begin{aligned} V_\text{0, annuity} &= V_\text{0, perp without growth from t=1} - V_\text{0, perp without growth from t=T+1} \\ &= \dfrac{C_\text{1}}{r} - \dfrac{ \left( \dfrac{C_\text{T+1}}{r} \right) }{(1+r)^T} \\ &= \dfrac{C_\text{1}}{r} - \dfrac{ \left( \dfrac{C_\text{1}}{r} \right) }{(1+r)^T} \\ &= \dfrac{C_\text{1}}{r}\left(1 - \dfrac{1}{(1+r)^T}\right) \\ \end{aligned}###

The equation of a perpetuity with growth is:

###V_\text{0, perp with growth} = \dfrac{C_\text{1}}{r-g}###

Question 704  utility, risk aversion, utility function, gamble

Mr Blue, Miss Red and Mrs Green are people with different utility functions.

Each person has $256 of initial wealth. A coin toss game is offered to each person at a casino where the player can win or lose $256. Each player can flip a coin and if they flip heads, they receive $256. If they flip tails then they will lose $256. Which of the following statements is NOT correct?

(a) All people would appear rational to an economist since they prefer more wealth to less.

(b) Mrs Green and Miss Red would appear unusual to an economist since they are not risk averse.

(c) Mr Blue's certainty equivalent of the gamble is $64. This is less than his current wealth of $256 which is why he would refuse the gamble.

(d) Miss Red's certainty equivalent of the gamble is $256. This is the same as her current wealth of $256 which is why she would be indifferent to playing or not.

(e) Mrs Green's certainty equivalent of the gamble is $512. This is more than her current wealth of $256 which is why she would love to play.

Question 713  effective rate conversion

An effective semi-annual return of 5% ##(r_\text{eff 6mth})## is equivalent to an effective annual return ##(r_\text{eff annual})## of:

(a) 30% pa

(b) 26.236426% pa

(c) 10.254219% pa

(d) 10.25% pa

Question 811  log-normal distribution, mean and median returns, return distribution, arithmetic and geometric averages

Which of the following statements about probability distributions is NOT correct?

(a) A normally distributed variable’s mean, median and mode are all expected to be equal.

(b) A log-normally distributed variable’s mean, median and mode are all expected to be different. Mean > median > mode.

(c) Future stock prices ##(P_t )## are often assumed to be log-normally distributed.

(d) Stocks’ annual net discrete returns ##(P_t/P_0-1)## must be normally distributed when stock prices ##(P_t)## are log-normally distributed.

(e) The total area under a probability density function (pdf) is always one.

A company has a 95% daily Value at Risk (VaR) of $1 million. The units of this VaR are in:

(a) Dollars ($).

(b) Dollars per day ($/day).

(d) Dollars squared per day ($^2/day).

(e) Dollars squared per day squared ($^2/day^2).

Question 893  balance of payments, current account

This question is about the Balance of Payments. Australia's current account as a percent of nominal gross domestic product (GDP) per annum is shown in the graph below.

Assume that all foreign and domestic assets are either debt which makes interest income or equity which makes dividend income, and vice versa for liabilities which cost interest and dividend payments, respectively.

Which of the following statements is NOT correct?

(a) TradeSurplus = Exports - Imports

(b) NetIncome = DividendsReceived + InterestReceived - DividendsPaid - InterestPaid

(c) CurrentAccountSurplus = NetIncome - TradeSurplus

(d) CurrentAccountSurplus = -1 × NetCapitalInflow = NetCapitalOutflow

Question 922  Stutzer portfolio performance indicator, Sharpe ratio, no explanation

Stutzer’s Portfolio Performance Indicator (PPI) ranks portfolios similarly to what other performance metric, assuming that the portfolios’ continuously compounded returns (LGDR’s) are normally distributed?

(a) Sharpe ratio.

(b) Treynor ratio.

(c) Jensen’s alpha.

(d) Sortino ratio.

Question 952  option, in the money option

If a put option is in-the-money, then the spot price (##S_0##) is than, than or to the put option's strike price (##K_T##)?

Question 981  margin loan, Basel accord, credit conversion factor

Margin loans secured by listed stock have a Basel III risk weight of 20%.

For margin loans that cannot be immediately cancelled by banks and asked to be repaid, the credit conversion factor (CCF) is 20%.

Suppose you have a stock portfolio worth $500,000, financed by:

• $300,000 of your own money; and
• $200,000 of the bank’s funds in the form of a margin loan which can only be cancelled by the bank after 5 days notice. The margin loan’s maximum LVR is 70%.

How much regulatory capital must the bank hold due to your margin loan? Assume that the bank wishes to pay dividends to its shareholders, so include the 2.5% capital conservation buffer in your calculations.

(a) $2100

(b) $4200

(c) $4800

(d) $5670

(e) $6300
