The article discusses financial options, which are agreements to buy or sell assets at a set price in the future. Options allow people to bet on the value of assets like stocks, currencies, or commodities. The value of an option depends on the underlying asset's value. Options are traded between a writer (like a bank) and a holder, who pays a premium for the option. The holder must decide when to exercise the option based on market conditions. The article focuses on standard options, explaining important terms and how to calculate the premium's fair value.
