We are now at time 0. We are given the following securities: XYZ stock. The time-0 price is S(0). A T-expiration European call on XYZ with strike price $15. The time-0 price is c(0,T, 15). A T-expiration European call on XYZ with strike price $20. The time-0 price is c(0, T, 20). Consider two possible positions: Position 1: Sell four 15-strike calls and buy three 20-strike calls. Position 2: Sell the stock short. For each position, plot the time-T payoff (only) as a function of the stock price at expiration. Plot the two payoffs on the same graph, for 0
