Suppose the current stock price of Alibaba is $20. Further suppose that a fund manager constructs the following trading strategy: 1. Buy a / share of Alibaba 2. Borrow $7.5 from the bank (assume 0% interest rate for this simple example) . This means that the net worth of such a portfolio = (amount of assets) - (amount of obligation) = 42 x $20 - $7.5 = $2.5 That is, if you are to invest in such a portfolio offered by the fund manager, the fair price is $2.5. Assume that one time period later, two possible scenarios: 1. stock price of Alibaba increases to $25 Net worth of the portfolio 2. stock price of Alibaba decreases to $15 = x $25 - $7.5 = $5 Net worth of the portfolio . Now, assume the current stock price of HSBC is Pnow = '* $15 - $7.5 = $0 Suppose that the stock price will either move up to Pups or move down to down at 1 time period later. . If the fund manager buys a fraction w share of HSBC, and borrows the amount m from the bank: Follow the preceding example to (i) compute the fair price of such a portfolio; (ii) determine the net worth of the portfolio at 1 time period later, for each of the two scenarios. Problem 3B Assume the data given in Problem 3A regarding the HSBC stock. Consider the following call option for the HSBC stock: * strike price = Prowi * expiration date = at 1 time period later. (a) Determine the worth of the call option at the expiration date, for each of the two scenarios (b) In order for both the call option described in Problem 3B and the portfolio described in Problem 3A to have exactly the same net worth for each of the two scenarios, how should the fund manager set values for w and m
