(1 point) Suppose S = $ 45, r= 3%, 9 (the annualized dividend yield) is 12 %, o (the annualized stock volatility) is 18 %. Consider the price of a $ 50 - strike put with 80 days to expiration. a) Suppose that 4 days later the price of the underlying asset has fallen to $ 43.85, using the Black-Scholes formula, compute the price of the $ 50 - strike put b) Suppose that 4 days later the price of the underlying asset has fallen to $ 43.85, using a delta approximation, estimate the price of the $ 50 - strike put (1 point) Suppose S = $ 45, r= 3%, 9 (the annualized dividend yield) is 12 %, o (the annualized stock volatility) is 18 %.
