Option Premium refers to the price that an option buyer pays to the option seller (writer) for acquiring the right, but not the obligation, to buy or sell an underlying asset at a predetermined price before or on a specific date. It represents the cost of entering into an options contract and is a crucial component of options trading.

The option premium is influenced by several factors, including the underlying assetís current market price, strike price, time to expiry, volatility, interest rates, and dividends. These elements are captured in option pricing models like the Black-Scholes model. Generally, higher volatility or longer time to expiration increases the premium, as the probability of favorable price movement grows.

An option premium consists of two parts: the intrinsic value and the time value. The intrinsic value is the immediate profit a holder could make if the option were exercised today. The time value reflects the potential for further gains before expiry and declines as the expiration date approaches, a phenomenon known as time decay.

For example, if a call option on a stock with a strike price of ?1,000 trades at ?50 while the stockís market price is ?1,030, the intrinsic value is ?30, and the remaining ?20 is the time value. Understanding this breakdown helps traders assess whether an option is fairly priced and aligns with their strategy.

In summary, the option premium represents both risk and opportunity. For buyers, it is the cost of leverage and flexibility; for sellers, it is the income earned for taking on risk. A sound understanding of how premiums are determined enables traders to make informed and risk-aware decisions in the derivatives market.
