Q5. Joel Franklin, CFA has just been promoted to junior portfolio manager for a large equity portfolio at Grant Investments, a large multinational investment banking firm. He is specifically responsible for the development of a new investment strategy that Grant Investments wants all equity portfolios to implement. Grant Investments has decided to begin overlaying option strategies on all equity portfolios. The reason for this decision is the relatively poor performance of many of their equity portfolios. They look at the option strategies as an opportunity to add value or reduce risk. Franklin recognizes that the behavior of an option's value is dependent on many variables and decides to spend some time closely analyzing this behavior. His analysis has resulted in the information shown in Exhibits 1 and 2 for European style options.
