Suppose that you buy a six-month call option on stock Y with an exercise price of $80 and sell a six-month call option on Y with an exercise price of $120. Draw a position diagram showing the payoffs when the options expire. (Hint: Determine and then add up the values of the two options given different share prices.)
Payoff from call option if stock price is more than the strike price = Stock price – Strike price
Payoff from call option if stock price is less than the strike price = 0
Therefore, Payoff table:
Stock Price (assumed price at the time of expire) |
Payoff (from buying a call option of strike price $80) |
Payoff (from selling a call option of strike price $120) |
Profit (payoff 1 + Payoff 2) |

Therefore Minimum profit is $0 and maximum profit is $40.
