Text Box: Hedging Risk with Put Options

On June 30, 1998, Harry Rockefeller purchases one share of Dell Computer stock for $94.25. However, Harry is worried about the possibility of Dell's price falling, so he decides to buy some European puts (expiring in 145 days, on November 22, 1998) with an exercise price of $80. Each put is priced at $5.25. As a function of the number of puts purchased, construct a worst-case and best-case scenario for the return earned on Harry's portfolio between June 30, 1998, and November 22, 1998, assuming that he sells his stock on the latter date. How does the analysis change if Harry purchases 100 shares rather than a single share?
