    Put option: A put option gives its buyer the right, but not the obligation, to sell a stock at the strike price prior to the expiration date. When you buy a call or put option, you pay a premium ...

  3. Binomial options pricing model - Wikipedia

    en.wikipedia.org/wiki/Binomial_options_pricing_model

    At each final node of the tree—i.e. at expiration of the option—the option value is simply its intrinsic, or exercise, value: Max [ (S n − K), 0 ], for a call option Max [ (K − S n), 0 ], for a put option, Where K is the strike price and is the spot price of the underlying asset at the n th period.

  4. Stock option return - Wikipedia

    en.wikipedia.org/wiki/Stock_option_return

    The following calculation assumes the sold call option and the purchased put option are both out-of-the-money and the price of the stock at expiration is the same as at entry: %If Unchanged Potential Return = (call option price - put option price) / [stock price - (call option price - put option price)]

    In mathematical finance, Margrabe's formula [1] is an option pricing formula applicable to an option to exchange one risky asset for another risky asset at maturity. It was derived by William Margrabe (PhD Chicago) in 1978. Margrabe's paper has been cited by over 2000 subsequent articles.

  8. Monte Carlo methods for option pricing - Wikipedia

    en.wikipedia.org/wiki/Monte_Carlo_methods_for...

    Here the price of the option is its discounted expected value; see risk neutrality and rational pricing. The technique applied then, is (1) to generate a large number of possible, but random, price paths for the underlying (or underlyings) via simulation, and (2) to then calculate the associated exercise value (i.e. "payoff") of the option for ...

  9. Finite difference methods for option pricing - Wikipedia

    en.wikipedia.org/wiki/Finite_difference_methods...

    The discrete difference equations may then be solved iteratively to calculate a price for the option. [4] The approach arises since the evolution of the option value can be modelled via a partial differential equation (PDE), as a function of (at least) time and price of underlying; see for example the Black–Scholes PDE. Once in this form, a ...
