3. Assuming that a one-year call option with an exercise price of \$28 is available for the stock of the DEW Corp., consider the following is a two-period price tree for DEW stock over the next year: You also know that the risk-free rate is RFR 5 percent per subperiod (or 10.25 percent annualized). a. If the sequence of stock prices that DEW stock follows over the year is \$30.00, \$33.00, and \$29.70, describe the composition of the initial riskless portfolio of stock and options you would form and all the subsequent adjustments you would have to make to keep this portfolio riskless. b. Given the initial DEW price of \$30, what are the probabilities of observing each of the three terminal stock prices in one year? (Hint: In arriving at your answer, it will be useful to consider (1) the number of different ways that a particular terminal price could be achieved and (2) the probability of an up or down movement.) c. Use the binomial option model to calculate the present value of this call option.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
