Table A1

b) Graph the box spread and indicate the pattern of profits from this trading in the figure.

c) Explain why treating American options as European when creating a box spread can lead to significant losses.

Using the data from the question above, assume additionally that the stock is trading at $169.

d) Calculate the intrinsic and time values of the call option with a strike price of $170.

e) Is there any arbitrage opportunity given the price on the put option with a strike price of $170? If this is the case, how much can be made risk-free – provide an example when the stock price is above the strike price, and vice versa?

f) What is the lowest possible price of the put with a strike price of $175?
