Question 1This strategy contains buying one call with a relatively low strike price (A), selling two calls with medium price (B), and buying one call with high strike price (C). Assume strike price is S.Payoff table of long butterfly spread[pic 1]When the spot price is lower than the strike price A, there is no profit from this strategy, no matter investors take long call option or short call option. Investors who take long call option would have profit, when spot price is greater than strike price A , by the amount of . When investors take short call option, they would get loss as long as spot price is bigger than strike price B (), and the loss would be S-B. When investors take long call option with strike price C, they would make a profit so long as spot price is greater than strike price C (), the profit equals to the value of (). [pic 2][pic 3][pic 4][pic 5][pic 6]Thus, we get the total payoff table. When spot price falls into the range between A and B, the total payoff is . When spot price falls into the range between B and C, the total payoff is . When spot price is higher than strike price C, the total payoff is.[pic 7][pic 8][pic 9]Let’s assume intervals among 0 to A, A to B, B to C are equal. Payoff Diagram:[pic 10]Investors adopt the butterfly spread strategy when they are certain that prices will fluctuate significantly and want to limit their downside risk.
