This homework is intended to show how to extend the multi-period binomial tree to price an option that pays dividends and has constant volatility. You are required to compute a value for the option using the portfolio replication and the risk-neutral probability approach. Please turn in a brief answer to all the questions.
? Consider International Business Machine Corporation (IBM). The shares of IBM are currently trading at $83. Assume the yearly volatility of IBM is 30% for the first two months and then, after two months, changes: if the price of the sock has increased in the two months the annualized volatility will decrease to 25% (for the next two months), while if the stock price decreased the annualized volatility will increase to 35%. Using a two step binomial tree approach, we are going to price options with 4 months to maturity. The annualized risk-free rate is equal to 5%. Let's also assume that the company pays a $5 dividend in two months. Note that the change in volatility will affect the stock only after the dividend is paid.
