Fight Finance

(a) If stock A's return increases, stock B's return is also expected to increase.

(b) If stock A's return decreases, stock B's return is also expected to decrease.

(c) If stock A and B were combined in a portfolio, there would be no diversification at all since they are positively correlated.

(d) Stock A and B's returns have positive covariance.

(e) a and b.

(a) 5%

(b) 7.5%

(c) 10%

(d) 15%

(e) 20%

(a) Exports denominated in domestic currency became cheaper to foreigners.

(b) Imports denominated in domestic currency became more expensive.

(c) Citizens would have to pay more in their own currency when holidaying in the US.

(d) USD interest payments on USD fixed-interest bonds became more expensive in their own currency.

(e) Domestic currency interest payments on fixed-interest bonds denominated in domestic currency became cheaper in their own currency.

Two call options are exactly the same, but one has a low and the other has a high exercise price. Which option would you expect to have the higher price, the option with the or exercise price, or should they have the price?

(a) $164.6662

(b) $181.1328

(c) $199.2461

(d) $226.2443

(e) $301.1312

(a) A price fall of $0.76 per pound.

(b) A price fall of $0.10 per pound.

(c) A price fall of $0.04 per pound.

(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) Option premium, option price.

(b) Strike price, exercise price.

(c) Payoff at maturity, profit.

(d) Maturity, expiry.

(e) Short, sell.

(a) 0.401817831

(b) 0.430922619

(e) 0.861038209

(b) Are freely available to absorb losses;

(c) Impose unavoidable servicing charges against earnings;
