Witrynafor some function, g(T). Now note that as K! 1 the call option price as well as its derivatives, CT, CK and CKK all go to zero. But (10) then implies that h(T) = g(T) = 0 for all Tafter which (10) reduces to (2). Given the implied volatility surface we can easily compute the corresponding call option price surface which is the graph of C(K,T ...

WitrynaShimko (1993, 1994) proposes an alternative approach by interpolating in the implied-volatility domain instead of the call-price domain. He begins by fitting a quadratic relationship between implied volatility and exercise price. The Black/Scholes formula is then used to invert the smoothed volatilities into option prices.
