Companies must pay interest and principal payments to debt-holders. They're compulsory. But companies are not forced to pay dividends to share holders. or ?

(a) The arithmetic average of variable X is represented by ##\bar{X}##.

(b) The standard deviation of variable X is represented by ##\sigma_X##.

(c) The variance of variable X is represented by ##\sigma_X^2##.

(d) The covariance between variables X and Y is represented by ##\sigma_{X,Y}^2##.

(e) The correlation between variables X and Y is represented by ##\rho_{X,Y}##.

(a) ##r_{0-3}## is the three year spot rate, given as an effective annual rate.

(b) ##r_{0-1}## is the one year forward rate, given as an effective annual rate.

(c) ##r_{1-2}## is the one year forward rate one year ahead, given as an effective annual rate.

(d) ##r_{2-3}## is the one year forward rate two years ahead, given as an effective annual rate.

(e) ##r_{1-3} = \left((1+r_{1-2})(1+r_{2-3})\right)^{1/2}-1## is the two year forward rate, one year ahead, given as an effective annual rate.

(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) You have the right to buy the underlying stock in 3 months’ time for a price of $50 if you want.

(b) If the dividend in 4 months were unexpectedly cancelled because the firm decided to re-invest its cash rather than pay it out then the 3 month call option price would be unaffected.

(c) If the stock price is $49 in 3 months then you wouldn’t exercise the ‘out of the money’ option.

(d) If the stock price is $51 in 3 months then you wouldn’t exercise or else you’ll incur a loss of $3.

(e) If the stock price is $57 in 3 months then you would exercise. Your profit would be $3 and payoff at maturity $7.

(d) Ole Peters.

(e) Paul Anthony Samuelson.

(a) The call option price is expected to be $654.757851.

(b) The stock investment value used for hedging should be $5506.488143, partly funded by $4845.505265 in debt.

(c) The interest expense on the borrowing from the previous day will be $0.663813.

(d) The gain on the stock is zero and the gain on the short call option is $6.225027.

(e) The net gain is $5.561214.
