Question 4B (10 points) Equity valuation is often described as part science, part art, and part craft. Explain why valuation is inherently difficult and discuss the major assumptions and judgments that make valuation estimates uncertain. Question 4C (13.34 points) Professional analysts use a variety of valuation models rather than relying on a single approach. Compare the major absolute valuation models (Dividend Discount Model, Discounted Cash Flow/Free Cash Flow models, and Asset-Based models) with relative valuation models.

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.
