In a recent closely contested lawsuit, Apex sued Bpex for patent infringement. The jury came back today with its decision. The rate of return on Apex was rA = 3.1%. The rate of return on Bpex was only rB = 2.5%. The market today responded to very encouraging news about the unemployment rate, and rM = 3%. The historical relationship between returns on these stocks and the market portfolio has been estimated from index model regressions as:Apex: rA = .2% + 1.4rM Bpex: rB = −.1% + .6rMOn the basis of these data, which company do you think won the lawsuit?

In a recent closely contested lawsuit, Apex sued Bpex for patent infringement. The jury came back today with its decision. The rate of return on Apex was rA = 3.9%. The rate of return on Bpex was only rB = 3.5%. The market today responded to very encouraging news about the unemployment rate, and rM = 3.6%. The historical relationship between returns on these stocks and the market portfolio has been estimated from index model regressions as: Apex: rA = 0.3% + 1.1rM Bpex: rB = −0.1% + 0.7rM a. What is the predicted returns for Apex & Bpex? (Do not round intermediate calculations. Round your answers to 1 decimal place.) b. Which company do you think won the lawsuit? Apex Bpex
Suppose that, after conducting an analysis of past stock prices, you come up with the following observations. Which would appear to contradict the weak form of the efficient market hypothesis? Explain.a. The average rate of return is significantly greater than zero.b. The correlation between the return during a given week and the return during the following week is zero.c. One could have made superior returns by buying stock after a 10% rise in price and selling after a 10% fall.d. One could have made higher-than-average capital gains by holding stocks with low dividend yields.

Mark Washington, CFA, is an analyst with BIC. One year ago, BIC analysts predicted that the U.S. equity market would most likely experience a slight downturn and suggested delta-hedging the BIC portfolio. As predicted, the U.S. equity markets did indeed experience a downturn of approximately 4% over a 12-month period. However, portfolio performance for BIC was disappointing, lagging its peer group by nearly 10%. Washington has been told to review the options strategy to determine why the hedged portfolio did not perform as expected. BIC owns 51,750 shares of Smith & Oates. The shares are currently priced at $69. A call option on Smith & Oates with a strike price of $70 is selling at $3.50 and has a delta of .69. What is the number of call options necessary to create a delta-neutral hedge?

Washington has been told to review the options strategy to determine why the hedged portfolio did not perform as expected. Washington considers a put option that has a delta of −.65. If the price of the underlying asset decreases by $6, then what is the best estimate of the change in option price?

Washington draws the value of an option as a function of the underlying stock price. Using this diagram, indicate how delta is interpreted. Delta is the:a. Slope in the option price diagram.b. Curvature of the option price graph.c. Level in the option price diagram.

The efficient markets hypothesis identifies three forms of market efficiency. (a) You observed that high-level managers make superior returns on investments in their company’s stock. Would this be a violation of weak-form market efficiency? Would it be a violation of strong-form market efficiency? (b) If the weak form of the efficient market hypothesis is valid, must the strong form also hold? Conversely, does strong form efficiency imply weak form efficiency? (c) Stock XYZ, which traded for several months at a price of K72, and then declines to K65. if the stock eventually begins to increase in price, K72 is considered a resistance level because investors who bought originally at K72 will be eager to sell their shares as soon as they can break even on their investment. If everyone in the market believes in resistance levels, why do these beliefs not become self-fulfilling prophecies?

As predicted, the U.S. equity markets did indeed fall, but BIC’s portfolio performance was disappointing, lagging its peer group by nearly 10%. Washington is reviewing the options strategy to determine why the hedged portfolio did not perform as expected. Required: After discussing the concept of a delta-neutral portfolio, Washington determines that he needs to further explain the concept of delta. He draws the value of an option as a function of the underlying stock price. In such a diagram, the option’s delta is the: a. Slope in the option price diagram b. curvature of the option price graph c. level of the option price
