Use the Excel spreadsheet Black Scholes Merton Binomial lOe.xlsm and determine the value of a call option and a put option on a stock currently priced at 100, where the risk-free rate is 5 percent (compounded annually), the exercise price is 100, the volatility is 30 percent, the option expires in one year, and there are no dividends on the stock. Let the number of binomial periods be 25. Verify that put-call parity holds?
