1. How many different volatilities would you expect to see for the stock? 2. Unfortunately, solving for the implied standard deviation is not as easy as Mal suggests. In fact, there is no direct solution for the standard deviation of the stock even if we have all the other variables for the BlackScholes model. Mal would still like you to estimate the implied standard deviation of the stock. To do this, set up a spreadsheet using the Solver function in Excel to calculate the implied volatilities for each of the options. 3. Are all of the implied volatilities for the options the same? ( Hint: No.) What are the possible reasons that can cause different volatilities for these options
