Consider a “long strangle” constructed from options which have an expiration date of August 15, 2014 (the third Friday in August). The following table displays the possible prices of Boeing stock on August 15, as well as the payoffs accruing to someone who holds a long strangle on Boeing stock:
Probability 0.2 0.3 0.2 0.2 0.1
Stock price $80 $90 $100 $110 $120
Gain from $15 $5 $0 $10 $20
long strangle
A long strangle is created using two options. For each option in the strangle above, indicate whether it is a put or a call, whether it is bought or sold, and calculate what its strike price is. Explain your answer.
