Opzione

Opzione is the Italian noun for "option" and denotes a choice or alternative among several possibilities. The term derives from Latin optio, from opt- "to choose," and it appears in many domains, from everyday language to specialized fields such as economics, law, and technology.

In decision making, an option is the available course of action, a potential arrangement or feature that a person can accept or reject. An option may be constrained by factors such as cost, risk, and time, and it can be described in terms of its value, likelihood, and consequences.

In finance, an opzione (option) is a contract that grants the holder the right, but not the obligation, to buy (call) or sell (put) an underlying asset at a specified price (strike) within a defined period. Key terms include underlying asset, strike price, expiration date, and premium. Options can be American or European in terms of exercise style and are priced using models such as Black-Scholes, incorporating volatility, time value, and risk-free rate. They are used for hedging and speculation.

In computing and software, options refer to configurable settings or command-line arguments that tailor the behavior of programs. In daily language, "opzione" also appears in legal and contractual contexts as an option clause granting a choice or renewal right to a party.
