Question:
Please try to make two-branch binomial tree for a stock price.
Assume a 1-year option expiry.
Using a volatility of 25%
Assume the stock price (spot and forward) is 200
What is the probability up and down for each step? What are your up and down amounts?
What would the price of a call option struck at 110% of the forward cost? (Hint: Recall risk neutral means you care only about expected payoffs. So just calculate a payoff and probability at the end of the tree.)
Now let's make this a one-branch normal model (so two outcomes at the end). Suppose forward interest rates are 2% and volatility is 1%. Time is 1 year. What is the up move and down move? Is the probability of 1% higher, the same, or more than the probability of 3%? What is the value of a 2% floor (payoff = max(2% - rate, 0)?
