American Option

An American option is a type of options contract that grants the holder the right — but not the obligation — to buy (in the case of a call option) or sell (in the case of a put option) the underlying asset at the predetermined strike price on any trading day up to and including the expiration date. This flexibility to exercise at any point during the option's life — rather than only at expiry — is the defining characteristic that distinguishes American options from European options, which can only be exercised on the expiration date itself. The early exercise feature makes American options generally more valuable than otherwise identical European options, particularly for deep in-the-money options and in situations where the underlying asset pays dividends. In Indian markets, most exchange-traded equity stock options on NSE follow the American-style exercise convention, while index options (such as Nifty and Bank Nifty options) follow the European style — a distinction that is critical for options traders on Ventura Securities when designing strategies and understanding exercise risk.
