(a) A long call option's payoff at maturity is equal to the maximum of zero or the underlying asset price at maturity minus the exercise price. ##f_\text{T,LC} = max(S_T - K, 0)##

(b) A long call option's profit is equal to the payoff at maturity less the initial option price. ##\pi_\text{LC} = max(S_T - K, 0) - c_0##

(c) The breakeven price is the underlying asset price at which a long option contract gives zero profit. When ##max(S_T - K, 0) - c_0 = 0##, then ##S_T = K+c_0##.

(d) A call option's break-even price is always more than its strike price.

(e) Call options should only be exercised at maturity if the underlying asset price is above the break-even price.

(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) ##\text{LGAGDR} = \text{AALGDR}##. This is always true, regardless of the distribution of the prices or returns and the number of return observations.

(e) ##\text{LAAGDR} = \text{AALGDR} + \text{SDLGDR}^2/2##. This is always true, regardless of the distribution of the prices or returns and the number of return observations.
