Part 2
 

Assume that the trading day is 1/3/2007, S&P 500 = 1416.63.
Use r = 5% / year
Strike prices are given in the options dataset #1.
 

1. Use volatility estimates (i),(iv),(v) from part 1 to compute the BS option prices for the expiry date 2/17/2007.
2. Compare with the options dataset #1.
3. Plot Option Price with volatility estimates (i),(iv),(v) vs Strike Price. Each on a separate graph; make 3 plots.
Plot the observed option price on each graph as well.
