Problem 6.4.26. (Given elasticity, what is o?) Assume the Black-Scholes framework. Consider a one-year at-the-money European put option on a nondividend-paying stock. You are given: (i) The ratio of the current put option price to the current stock price is 0.073445. (ii) The current put-option elasticity is -5.941861. (iii) The continuously compounded risk-free interest rate is 1.2%. Determine the stock's volatility. Problem 6.4.26. (Given elasticity, what is o?) Assume the Black-Scholes framework.
