Consider the following one-period binomial model for stock price. At t = 0 the stock price is $80 and at t = 1 (t is in years) it could be $70 with probability p > 0 and $y with probability 1 − p. The interest rate is assumed to be 8%. (1) Determine the range of values for y that precludes arbitrage in this model. (2) Assume that y = $83. Construct an arbitrage strategy for this model.1

Consider the binomial model for an American call and put on a stock whose price is $90. The exercise price for both the put and the call is $65. The standard deviation of the stock returns is 25 percent per annum, and the risk-free rate is 6 percent per annum. The options expire in 120 days. The stock will pay a dividend equal to 4 percent of its value in 60 days. (a) Draw the three-period stock tree and the...
