(a) ##r_\text{total} = \dfrac{c_1+p_1-p_0}{p_0} ##

(b) ##r_\text{total} = \dfrac{c_1+p_1}{p_0} - 1##

You buy a house funded using a home loan. Have you or debt?

(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##.

(a) Basis risk makes hedges more risky.

(b) Basis risk can only lead to worse than expected effective dollar prices.

(c) Basis risk only occurs when the future is closed out early, before it matures.

(d) ‘The basis’ is defined as the underlying spot price less the futures price quote ##(S_t - F_{t,T})##.

(e) The futures price of oil will tend to be higher than the spot price due to storage costs, so the basis will tend to be positive for hedgers who long futures contracts.

(b) For a ‘rainy day’ such as becoming sick and having to pay for a doctor.

(c) To preserve their wealth, such as keeping cash under the bed, in the piggy bank or in a safe.

(d) To invest in assets such as houses, shares or bonds if they become cheap.
