Call Option Definition

A call is a type of option contract that gives the buyer of a call the right, but not the obligation to purchase a stock or ETF at a given price (Strike Price) if exercised by a specific date (Expiration Date).

If the price of the underlying asset is not above (for calls) or below (for puts) the option’s strike price, then the option will expire worthless.

Otherwise, the owner of a call can choose to sell it, and or if it is in-the-money, the owner can execute the option and purchase 100 shares per contract of the underlying security at the strike price.
