5. Some people find options expensive and use more complex structures to reduce the cost. For
example, consider buying a call with a strike of $55 and selling a call with a strike of $60.
a. What is the cost of establishing this combined position?
b. What is the payoff of the combined position if the market price goes to $60?
c. What is the payoff of the combined position if the market price goes to $100?
3. An investor has $1,000 to invest. They believe the price of the underlier will increase to $60
within one year.
a. How many shares of stock could they buy with the $1,000 at the current price of $50,
and how much would they make if the share price increased to $60?
b. How many calls with a strike of $55 could they buy for the same $1,000, and how
much would they make if the share price increased to $60?
c. How much would they make (or lose) from the stock and from the calls if the share
price declined to $40?
4. What is the premium on a call with a strike of $0.01? Why is the premium so close to the $50
share price?
1. We want to examine the comparative statics of the Black Scholes model. Complete the
following table using the Excel model from class or another of your choice. Provide the call
premium and the put premium for each scenario.
