The Black-Scholes model values a call option by weighting the current price of the underlying asset with the probability that the stock price will be higher than the exercise price and subtracting the probability-weighted present value of the exercise price. The value of a call option at expiration equals the spot price of the underlying asset minus its exercise price also called the strike price i.
at which the option entitles you to purchase the underlying asset. This can be expressed mathematically as follows:. Where C is the value of call option all called call premiumS is the spot price of the underlying and X is the exercise price. At any time before the expiration, the black scholes fair values of binary options c of the call option equals the current stock price minus the present value of the strike price, this can be express as follows:.
Where r is the risk-free rate of interest and t is the time to expiration. The above expression gives us the value of the call in a static scenario i. If we want to know the value of a call option based on our expectation, we can write the following crude expression of probability weighted cash inflows and out flows:. The Black-Scholes formula is a refined form of the expression above.
Given a stock price S, exercise price X, annual risk-free rate r, time to maturity t and annual standard deviation of return of the underlying asset σ, we black scholes fair values of binary options c determine the value of call option using the following formula:. Where N d 1 and N d 2 represent the standardized normal distribution probability that a random variable will be less than d 1 and d 2 respectively when d 1 and d 2 are given by the following equation:.
N d 1 and N d 2 roughly represent that probability that the exercise price of the option will be higher than the current stock price and hence the option will be in-the-money and hence valuable.
The Black-Scholes option formula can also be used to estimated implied volatility based on the current call premiums. We need to determine the value of the call option using Black-Scholes option pricing model and then compare it with the current price of the option and purchase the option if it is fairly priced.
Next, we can find the standardized normal distribution probability using Microsoft Excel NORMSDIST function. Once we have N d 1 and N d 2we can plug-in the relevant numbers in the Black-Scholes formula:. The option value as per the model is lower than the premium on the call options currently traded. It might be because the option is overvalued or because black scholes fair values of binary options c estimate of the volatility is lower.
If we have current value of call premium C, stock price S, exercise price X, time to maturity t and risk-free rate r, we can work back to find out the implied volatility, black scholes fair values of binary options c. It can be worked out using Excel Goal Seek tool. by Obaidullah Jan, ACA, CFA and last modified on Jun 10, Studying for CFA ® Program?

From this model you can derive the theoretical fair value of an options contract 9. · Under the usual Black–Scholes assumptions, there is an explicit formula for the fair value of this option. We only consider in detail the case where the lower barrier is set below the option’s strike price, E > B−. In so doing, we see that there is a neat short cut which allows us to do many apparently more complicated cases with little File Size: KB
