The calls are European, which does not allow for early exercise. The B-S option pricing model is formulated as followed: In this example, we derived call and put option price based on the Black-Scholes model. The function procedures are used. The first function, SNorm zcomputes the probability from negative infinity to z under standard normal curve.

The second function and the third function compute call and put prices, respectively. The call price is computed on cell C13, and the put price on cell C The two formulas are listed on B17 and B18 for reference purpose.

Black-Scholes Option Pricing Model. Once we have the price for a call option, we can derive the price of the put option which written against the same stock with the same exercise price using the put-call parity developed by Stoll in

Volatility Skew Implied volatility can be computed for both puts and calls across a range of different strike prices.

Interestingly, it is common for the implied volatility to vary across this range. Plotting the implied volatility against the strike price results in a curve that is termed the 'volatility smile'. This is due to the fact that it is common for out of the money calls and puts to have higher implied volatilities.

When there is a difference between the implied volatilities using equal out of the money calls and puts, this is termed the 'volatility skew'. Interpretation of the skew is the basis for some trading activities.

If the ratio of Call volatility to Put volatility is considered, a value greater than one may imply that the calls are priced higher than puts with a resulting upward price bias and vice versa, ie. High skew ratios may indicate demand increasing for puts, ie there are relatively more puts being bought and calls being sold, than puts being sold and calls being bought. The analysis and interpretation of volatility skew should be undertaken with due care and diligence and is a matter for skilled, professional traders.
