A financial option is a financial derivative that involves a contract to buy or sell an underlying asset, such as a stock, currency pair, commodity or other, which grants the buyer the right to buy or sell the agreed underlying asset at a future date previously agreed, depending on whether it is a call option or a put option.
The main characteristics of an option are indicated by its own name. The term ‘option’ refers precisely to the fact that the buyer of this financial derivative has the right (has the option) to execute the provisions of the contract. At the same time, the seller of an option is required to buy or sell (depending on the type of option) if the buyer exercises his right once the contract expires.
