Fight Finance

(a) Negative since the NPV is negative.

(b) Zero since the project's internal rate of return is less than the required return.

(c) 15 years.

(d) 18 years.

(e) Infinite, since the project will never pay itself off.

(a) You have bought the right to buy a BHP share for $40 in 6 months.

(b) You have bought the right to sell a BHP share for $40 in 6 months.

(c) You have bought the obligation to sell a BHP share for $40 in 6 months.

(d) You have sold the right that allows your counterparty to buy a BHP share from you for $40 in 6 months. This means that you have the obligation to sell a BHP share to your counterparty for $40 in 6 months if he wants to buy it.

(e) You have sold the right that allows your counterparty to sell a BHP share to you for $40 in 6 months. This means that you have the obligation to buy a BHP share from your counterparty for $40 in 6 months if he wants to sell it.

An abandonment option is best modeled as a or option?

(a) Mr Blue, Miss Red and Mrs Green all prefer more wealth to less. This is rational from an economist's point of view.

(b) Mr Blue is risk averse. He will not enjoy a fair gamble and would like to buy fairly priced insurance.

(c) Miss Red is risk-neutral. She will not enjoy a fair gamble but wouldn't oppose it either. Similarly with fairly priced insurance.

(d) Mrs Green is risk-loving. She would enjoy a fair gamble and would dislike fairly priced insurance.

(e) Mr Blue would like to buy insurance, but only if it is fairly or under priced.

(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) Price must be greater than zero (p>0).

(b) Price can be greater than its exercise price (p>K).

(c) Price can be greater than the underlying asset's price (p>S).

(d) Exercise price can be greater than the underlying asset's price (K>S).

(e) Profit must be less than the payoff at maturity from the long trader’s perspective.

(a) $1.550849674

(b) $0.982509295

(c) $0.666414943

(d) $0.287263739

(e) $0.055037262

(a) Have Sharpe ratios equal to the market’s.

(b) Have Treynor ratios equal to the market's.

(c) Have Jensen’s alphas that are zero.

(d) Not necessarily be bought or sold since there's no gain either way.

(e) Plot on the Security Market Line (SML).

(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.

(a) Coupon rate is equal to the benchmark rate plus a premium.

(b) Premium is also commonly called a spread or margin.

(c) Premium rate is fixed. The number is written in the bond contract and does not change.

(d) Benchmark rate is fixed. The number is written in the bond contract and does not change.

(e) Paying quarterly US dollar coupons often use the 90-day USD LIBOR rate as the benchmark.
