A call option is a financial contract between two parties, the buyer and the seller of this type of option. It is the option to buy shares of stock at a specified time in the future. Often it is simply labeled a "call". The buyer of the option has the right, but not the obligation to buy an agreed quantity of a particular commodity or financial instrument from the seller of the option at a certain time (the expiration date) for a certain price.
