Problem
Find a stock that pays dividend over the next 30 business days that is optionable. Construct a binomial tree in excel using the Cox-Ross-Rubenstein method where each time step represents one day such that At = 1/365 and the initial price is the current price (make sure that the tree works so that it adjusts to whatever the initial stock price is). Use o = 0.3 as a starting point. Use an interest rate of 1.48%. Extend the tree with enough branches so that you can price options with the first or second maturity following the dividend payment. For example, if the stock pays dividend November 20th, you could price options with maturity on Nov 22d or Nov 27th. If the stock's ex-dividend date coincides with an option expiration, pick an option that expires later.
