(a) 1: short call, 2: long call, 3: short put, 4: long put.

(b) 1: long call, 2: long put, 3: short call, 4: short put.

(c) 1: short put, 2: long put, 3: short call, 4: long call.

(d) 1: long put, 2: short put, 3: long call, 4: short call.

(e) 1: long put, 2: short call, 3: short put, 4: long call.

(a) Diversifiable standard deviation of asset returns.

(b) Systematic standard deviation of asset returns.

(c) Proportion of debt and equity used to fund the assets.

(d) Cash flows from assets.

(e) Risk free rate.

(a) ##\min(S_T - K, 0)##.

(b) ##-\min(S_T - K, 0)##.

(c) ##\max(K-S_T, 0)##.

(d) ##-\max(K-S_T, 0)##.

(e)##-\max(S_T-K, 0)##.

(a) Option premium is another name for option price.

(b) An option contract's price is always changing.

(c) Strike price is another name for exercise price.

(d) An option contract's strike price is always changing.

(e) Call and put option premiums are paid at the start when the option is bought. Call option exercise prices are paid when they are exercised, usually at maturity.

(a) The geometric average of the gross discrete returns (GAGDR) equals 1.04075 which is 104.075%.

(b) ##\exp \left( \text{GAGDR} \right) = \text{AALGDR}##. The natural exponent of the GAGDR equals the arithmetic average of the logarithms of the gross discrete returns (AALGDR).

(c) ##\text{GAGDR}^T = \left( P_T/P_0 \right)##. The GAGDR raised to the power of the number of time period that it's measured over equals the ratio of the first and last prices.

(d) ##\text{GAGDR} = \exp \left( \text{AALGDR} \right)##. This is always true, regardless of the distribution of the prices or returns. The logarithm of the geometric average of the gross discrete returns (LGAGDR) is always equal to the arithmetic average of the logarithm of the gross discrete returns (AALGDR).

(e) ##\text{AAGDR} \approx \exp \left( \text{AALGDR} + \text{SDLGDR}^2/2 \right)##. This is only approximately true and depends on the distribution of the prices and returns. It's asymptotically true as the time period that the returns are measured over reaches infinity.

(a) Firm A is less risky than Firm B. Firm A would have a higher credit rating.

(b) Firm A has the absolute advantage issuing bonds in both the fixed and floating coupon bond markets.

(c) Firm A has a comparative advantage issuing bonds in the floating coupon bond market.

(d) The net benefit from the swap available to Firm A is 0.25%.

(e) The swap rate between Firm B and the Bank would be 2.5% pa.

(a) The mean (expected or arithmetic average) portfolio value in one year is $1,072,508. The median (50th percentile) portfolio value in one year is $1,051,271.

(b) The annual 99% relative VaR is $391,591.

(c) The annual 99% absolute VaR is $340,320.

(d) The 98% confidence interval of portfolio values in one year ##(V_1)## is ##\$659,680 < V_1 < \$1,675,312,977##.

(e) The 98% confidence interval of continuously compounded portfolio returns over the next year ##(r_{0 \rightarrow 1})## is ##-41.6\% < r_{0 \rightarrow 1} < 51.6\%##.

(a) Best day of the 5% worst days’ results.

(b) Worst day of the 5% worst days’ results.

(c) Best day of the 5% best days’ results.

(d) Worst day of the 5% best days’ results.

(e) Best day of the 95% worst days’ results.

(a) The initial futures price would be $39.1828.

(b) The initial value of the futures contract would be zero.

(c) If the spot price rose to $45 at month 1, then the value of the futures contract would be positive $4.8999 at that time.

(d) If the spot price fell to $35 at month 3, then the value of the futures contract would be negative $4.1828 at that time.

(e) If the spot price remained at $40 until maturity, then the value of the futures contract would be positive $0.8172 at that time.

(a) Right now, borrow USD in America, convert it into AUD at the spot, lend it in Australia, lock in to buy USD and sell AUD forward one year. One year later, withdraw the AUD, convert it into USD and pay back the USD loan.

(b) American debt may be over-priced, sell it.

(c) Australian debt may be under-priced, buy it.

(d) The spot AUD may be under-priced compared to the USD, buy the AUD now.

(e) The forward AUD may be under-priced compared to the USD, lock in to buy the AUD in one year.
