A financial contract between two parties i.e. the buyer and the seller of this type of option, is referred to as a call option. It is the option to buy shares of stock at a specified time in the future. Usually it is simply labeled a “call”. In call option, the buyer of the option has the right, but it is not the obligation to buy an agreed quantity of a particular commodity or financial instrument (the underlying instrument) from the seller of the option at a certain time (the expiration date) for a certain price (the strike price). The seller (or “writer”) is obligated to sell the same commodity or financial instrument that is so decided by the buyer. For this right the buyer pays a fee that is referred to as a premium.
Buyer and Seller Anticipation
It is the will of the buyer of a call option that the price of the underlying instrument may rise in the future; the seller either anticipates that it will not rise, or he might be willing to give up some of the upside (profit) from a price rise in return for the premium (paid immediately) and retaining the opportunity to make a gain up to the strike price.
