Question 679 option, no explanation

A trader sells one crude oil European style call option contract on the CME expiring in one year with an exercise price of $44 per barrel for a price of $6.64. The crude oil spot price is $40.33. If the trader doesn’t close out her contract before maturity, then at maturity she will have the:

Question 721 mean and median returns, return distribution, arithmetic and geometric averages, continuously compounding rate

Fred owns some Commonwealth Bank (CBA) shares. He has calculated CBA’s monthly returns for each month in the past 20 years using this formula:

###r_\text{t monthly}=\ln⁡ \left( \dfrac{P_t}{P_{t-1}} \right)###

He then took the arithmetic average and found it to be 1% per month using this formula:

###\bar{r}_\text{monthly}= \dfrac{ \displaystyle\sum\limits_{t=1}^T{\left( r_\text{t monthly} \right)} }{T} =0.01=1\% \text{ per month}###

He also found the standard deviation of these monthly returns which was 5% per month:

###\sigma_\text{monthly} = \dfrac{ \displaystyle\sum\limits_{t=1}^T{\left( \left( r_\text{t monthly} - \bar{r}_\text{monthly} \right)^2 \right)} }{T} =0.05=5\%\text{ per month}###

Which of the below statements about Fred’s CBA shares is NOT correct? Assume that the past historical average return is the true population average of future expected returns.

(a) The returns ##r_\text{t monthly}## are continuously compounded monthly returns and are likely to be normally distributed, so the mean, median and mode of these continuously compounded returns are all equal to 1% per month.

(b) The annualised average continuously compounded return is ##\bar{r}_\text{cc annual}=12×0.01=0.1=12\%\text{ pa}##. The annualised standard deviation is ##\sigma_\text{annual} = \sqrt{12}×0.05=0.173205081=17.32\%\text{ pa}##.

(c) Over the next 10 years the mean, median and mode continuously compounded 10 year returns will all equal ##0.01 \times 12 \times 10 = 120\%##.

(d) Over the next 10 years the expected mean gross discrete 10 year return is ##e^{(0.01 - 0.05^2/2)×12×10} = 2.857651118## and the median gross discrete 10 year return is ##e^{(0.01 + 0.05^2/2)×12×10}=3.857425531##.

(e) If the current price of the CBA shares is $75, then in 10 years they’re expected to have a mean value of ##75×e^{(0.01 + 0.05^2/2)×12×10} = 289.3069148## and a median value of ##75×e^{0.01×12×10}=249.0087692##.

Question 786 fixed for floating interest rate swap, intermediated swap

The below table summarises the borrowing costs confronting two companies A and B.

Bond Market Yields
	Fixed Yield to Maturity (%pa)	Floating Yield (%pa)
Firm A	3	L - 0.4
Firm B	5	L + 1

Firm A wishes to borrow at a floating rate and Firm B wishes to borrow at a fixed rate. Design an intermediated swap (which means there will actually be two swaps) that nets a bank 0.1% and shares the remaining swap benefits between Firms A and B equally. Which of the following statements about the swap is NOT correct?

Question 828 future, future valuation, no explanation

You bought a 1.5 year (18 month) futures contract on oil. Oil storage costs are 4% pa continuously compounded and oil pays no dividends. The futures contract is entered into when the oil price is $40 per barrel and the risk-free rate of interest is 10% per annum with continuous compounding.

Which of the following statements is NOT correct?

Question 861 open interest, closing out future contract, no explanation

Alice, Bob, Chris and Delta are traders in the futures market. The following trades occur over a single day in a newly-opened equity index future that matures in one year which the exchange just made available.

1. Alice buys 2 future from Bob.

2. Chris buys 5 futures from Delta.

3. Chris buys 9 futures from Bob.

These were the only trades made in this equity index future.

Which of the following statements is NOT correct?

Question 894 balance of payments, current account, no explanation

Below are four graphs of Australia's external position, published in the RBA's chart pack.

Assume that all assets and liabilities are debt which makes interest income and equity which makes dividend income.

Which of the following statements is NOT correct? As at the end of 2017, Australia’s:

(a) Trade surplus was roughly zero, so Australians exported as much as they imported.

(b) Net Income was negative, so Australians paid more dividends and interest to foreigners than they received. This is probably because Australia has greater gross foreign liabilities than gross foreign assets.

(c) Current account deficit means Australians have to lend to foreigners by buying foreigners’ debt and equity which represent net capital outflows out of Australia.

(d) Net foreign equity liabilities were negative (less than zero) so Australians had positive net foreign equity assets which means that Australians owned more foreign shares than foreigners owned of Australian shares.

(e) Persistent current account deficit will make its net foreign liabilities greater and greater.

Question 929 standard error, mean and median returns, mode return, return distribution, arithmetic and geometric averages, continuously compounding rate

The arithmetic average continuously compounded or log gross discrete return (AALGDR) on the ASX200 accumulation index over the 24 years from 31 Dec 1992 to 31 Dec 2016 is 9.49% pa.

The arithmetic standard deviation (SDLGDR) is 16.92 percentage points pa.

Assume that the data are sample statistics, not population statistics. Assume that the log gross discrete returns are normally distributed.

What is the standard error of your estimate of the sample ASX200 accumulation index arithmetic average log gross discrete return (AALGDR) over the 24 years from 1992 to 2016?
