Case Presentation

Please read the case of The Keller Fund’s Option Investment Strategies and try your best to answer the following questions as much as possible with your teammates. Based on your answers, each team will make a PPT presentation in the class of July 2. Good luck!

1. To analyze the profit and loss possibilities inherent in the option investment strategies, please perform the following analyses for call and put options on Lotus’s common stock that mature in February 1994 and that have an exercise price of $55 per share.

a) Compute net profits and losses per share (actual dollar profits and losses, not rates of return) at expiration (February 19, 1994) for the following investment strategies:

i. Buying a call option on Lotus’s stock;

ii. Writing a call option on Lotus’s common stock;

iii. Buying a put option on Lotus’s common stock;

b) For each of the option investment strategies listed above, draw a graph relating possible profits and losses per share to Lotus’s stock price at the time of expiration. Put profits and losses per share on the vertical axis of your graph and stock prices on the horizontal axis.

c) Compute profits and losses per share, and graph them against stock prices for the strategy of buying a share of Lotus’s common stock at $55 per share and holding it until February 19, 1994.

2. Study the graph created in your answer to question 1. Which of the various strategies examined offers the greatest upside return? The...
