An option is a contract to buy or sell a specific financial product .Options are financial instruments that convey the right, but not the obligation, to engage in a future transaction on some underlying security, or in a futures contract. The option is traded both on OTC and in the Exchange.A call option gives the holder the right to buy the underlying assert by certain date for a certain price.A put option gives the holder the right to sell the underlying assert by certain date for a certain price.The Price in the contract is known as strike price,the date in the contract is known as the maturity.

The theoretical value of an option can be determined by a variety of techniques. These models, which are developed by quantitative analysts, can also predict how the value of the option will change in the face of changing conditions. Hence, the risks associated with trading and owning options can be understood and managed with some degree of precision compared to some other investments.

Types of options

Exchange traded options are a class of exchange traded derivatives. Since the contracts are standardized, accurate pricing models are often available.

Over-the-counter options (OTC ) are traded between two private parties, and are not listed on an exchange. The terms of an OTC option are unrestricted and may be individually tailored to meet any business need.

Forward Contract

A forward contract is an agreement between two parties to buy or sell an asset at a specified point of time in the future. The forward price of such a contract is the spot price, which is the price at which the asset changes hands on the spot date.One of the party to a forward contract assumes a long position and agree to buy the underlying assert,on the other hand ,the other party assumes a short position and agree to sell the assert.

This process is used in financial operations to hedge risk, as a means of speculation, or so as to allow a party to take advantage of a quality of the underlying instrument which is time-sensitive.

The forward market is the over-the-counter financial market in contracts for future delivery, so called forward contracts. Forward contracts are personalized between parties. The forward market is a general term used to describe the informal market by which these contracts are entered into. Standardized forward contracts are called futures contracts and traded on a futures exchange.
