Two breakeven points, S* = 135 and S* = 155c. One breakeven point, S* = 150d. Two breakeven points, S* = 130 and S* = 170

Answer 1

Answer:

D) Two break even points, S* = 130 and S* = 170

Explanation:

option a)

if the stock price is $145,

put option ⇒ you win $5 - $5 (option price) = no gain

call option ⇒ you lose $15 (option price)

WRONG ANSWER

option b)

if the stock price is $155,

put option ⇒ you lose $5 (option price)

call option ⇒ you win $5 - $15 (option price) = -$10 loss

WRONG ANSWER

option c)

if the stock price is $150,

put option ⇒ you lose $5 (option price)

call option ⇒ you lose $15 (option price)

WRONG ANSWER

option d)

if the stock price is $170,

put option ⇒ you lose $5 = -$5 loss

call option ⇒ you win $20 - $15 (option price) = $5 gain

total gain/loss = $0

if the stock price is $130,

put option ⇒ you win $20 - $5 (option price) = $15 gain

call option ⇒ you lose $15 (option price)

total gain/loss = $0
