\"American
\nAmerican option pricing\u00a0is the binomial options pricing model that provides a generalizable numerical method for the valuation of options.<\/p>\n

American options are contracts that may be exercised early, prior to expiry.<\/span><\/p>\n

These options are contrasted with European options for which exercise is only permitted at expiry. Most traded stock and futures options are ‘American style’, while most index options are European.<\/span><\/p>\n

The exercise style of listed options is American by default. Except for options on equity market indexes such as the S&P 500 index.<\/span><\/p>\n

Options on futures are typically American as well.<\/span><\/p>\n

The Black-Scholes pricing formulas are not applicable to American option pricing.<\/span><\/p>\n

Being an algorithm, binomial option pricing models, nevertheless, can be modified to take care of the added complication in the American option.<\/span><\/p>\n
