A stock has not been fluctuating much in price. Its average price is $20/share. You expect that the stock price behaves the same way in the next year. A one-year put option is selling for $5, which has an exercise price of $20. Suppose the risk-free rate is 0.05. To make use of your expectation in the future price movement, you establish a straddle strategy to maximize your profits. If the stock price actually ends up at $20 in a year, your profit is $ . Give your answer to 2 decimal places.

The variance? The standard deviation? b) If the expected T-bill rate is 3.80%, the expected inflation rate is 3.50% what are the approximate and exact expected real returns on the portfolio? what is the approximate real risk premium? Show your steps.
For a two-period binomial model, you are given: Each period is one year. The current price for a non dividend-paying stock is 20. u = 1.2840, where u is one plus the rate of capital gain on the stock per period if the stock price goes up. d = 0.8607, where d is one plus the rate of capital loss on the stock per period if the stock price goes down. The continuously compounded risk-free interest rate is 5%. Calculate the price of an American call option on the stock with a strike price of 22.
