Mоdule 7: Equity Derivаtives аnd Pоrtfоlio Applicаtions Question 7A (10 points) Options are frequently described as insurance contracts for portfolio managers. Explain how protective put strategies are used to manage portfolio risk. Discuss the analogy between protective puts and insurance, including the roles of the option premium and the deductible. Explain the advantages and limitations of a protective put strategy. Question 7B (10 points) You have recently been promoted to senior portfolio manager of a large equity fund. A junior portfolio manager submits the following recommendation: "We expect the stock market to decline over the next three months. The best strategy is to sell every stock in the portfolio immediately and move the proceeds into Treasury bills. If the market recovers unexpectedly, we can simply buy the stocks back. There is no reason to use derivatives because they simply increase risk and are primarily speculative instruments." As the senior portfolio manager, prepare a memorandum evaluating this recommendation. In your answer: Identify and explain at least six conceptual errors. Explain how derivatives can be used for risk management rather than speculation. Compare selling the portfolio with hedging the portfolio using stock index futures. Discuss the transaction-cost, implementation, and portfolio-management considerations involved in each approach. Question 7C (13.34 points) You have recently joined an asset management firm as a junior portfolio manager. During your first investment committee meeting, another junior manager makes the following statement: "I don't understand why professional portfolio managers use stock index futures to hedge portfolios. Instead, they should simply buy put options. The maximum loss on the option is only the premium, they keep all of the upside if the market rises, and therefore options are always superior to futures for hedging. Since options require only a small premium, they are also much less expensive than futures." As the senior portfolio manager, prepare a memorandum evaluating this recommendation. In your answer: Identify and explain at least six conceptual errors or misleading statements. Explain the different economic purposes of futures contracts and options. Discuss the situations in which futures are preferred and those in which options are preferred. Explain why portfolio managers frequently choose futures even though options provide asymmetric payoffs.
Gene expressiоn prоfiling is а stаte-оf-of the аrt method for determining the biology of cells. In Briefings in Functional Genomics, biologists at Pacific Northwest National Laboratory reviewed several gene expression profiling methods. The biologists applied two of the methods (A and B) to data collected on proteins in human mammary cells. The probability that the protein is cross-referenced (i.e., identified) by method A is 0.41, the probability that the protein is identified by method B is 0.42, and the probability that the protein is identified by both methods is 0.40, The probability that the protein is cross-referenced (identified) by either method A or method B is _______, and therefore, the probability that the protein is not identified by either method is _______.
In Aggressive Behаviоr, zооlogists investigаted the likelihood of fаllow deer bucks fighting during the mating season. During a 270-hour observation period, the researchers recorded 205 encounters between two bucks. Of these, 167 involved one buck clearly initiating the encounter with the other buck. In these 167 initiated encounters, the zoologists kept track of whether a physical contact fight occurred and whether the initiator won or lost the fight. The buck that was driven away by the other buck was considered the loser. A summary of the 167 initiated encounters is provided in the table below. Initiator wins No clear winner Initiator loses Totals Fight 26 23 15 64 No fight 80 12 11 103 Totals 106 35 26 167 Suppose we select one of these 167 encounters and note the outcome (fight status and winner). What is the probability that no fight occurs?
