Assume r = 8%, σ = 30%, δ = 0. Using 1-year-to-expiration European options, construct a position where you sell two 80-strike puts, buy one 95-strike put, buy one 105-strike call, and sell two 120-strike calls. For a range of stock prices from $60 to $140, compute delta, vega, theta, and rho of this position. As best you can, explain intuitively the signs of the Greeks.
Answer to relevant QuestionsConsider a perpetual call option with S = $50, K = $60, r = 0.06, σ = 0.40, and δ = 0.03. a. What is the price of the option and at what stock price should it be exercised? b. Suppose δ = 0.04 with all other inputs the ...Let S = $100, K = $120, σ = 30%, r = 0.08, and δ = 0. a. Compute the Black-Scholes call price for 1 year to maturity and for a variety of very long times to maturity. What happens to the option price as T →∞? b. Set δ ...Suppose you sell a 45-strike call with 91 days to expiration. What is delta? If the option is on 100 shares, what investment is required for a delta-hedged portfolio? What is your overnight profit if the stock tomorrow is ...You have written a 35-40-45 butterfly spread with 91 days to expiration. Compute and graph the 1-day holding period profit if you delta- and gamma-hedge this position using the stock and a 40-strike call with 180 days to ...Consider a 40-strike 180-day call with S = $40. Compute a delta-gamma-theta approximation for the value of the call after 1, 5, and 25 days. For each day, consider stock prices of $36 to $44.00 in $0.25 increments and ...
