Consider a two period economy. You can buy stocks in period 0, and then sell them in period 1. You can also enter into futures contracts in period 0, which expire in period 1.
Suppose a stock has a β of 0.5. The stock pays no dividends, and is trading at $100. The market has an expected return of 10%. The interest rate is 2%. Suppose the CAPM holds. What is the stock’s expected return? What is the expected price of the stock in period 1?
Consider a futures contract on the stock, expiring at t = 1. What is the fair price of the futures contract, in t = 1 dollars?
Suppose you take a long position in the futures contract in period 0 (so, you promise to pay money, in exchange for getting the stock in period 1). When the futures contract expires in period 1, you receive the stock and immediately sell it. What is the expected amount you will pay in money for the stock? What is the expected amount you get from selling the stock?
Since buying single-stock futures appears to be a fairly…
Consider a put option on a stock that currently sells for £100, but may rise to £120 or
fall to £80 after 1 year. The risk free rate of return is 10%, and the exercise price is £90.
(a) Calculate the value of the put option using the risk-neutral valuation relationship
(RNVR). Explain the reasoning behind your calculations.
