The Options can be classified into following types:
Exchange-traded options
Exchange-traded options (also called "listed options") are a class of exchange-traded derivatives. Exchange traded options have standardized contracts, and are settled through a clearing house with fulfillment guaranteed by the credit of the exchange. Since the contracts are standardized, accurate pricing models are often available. Exchange-traded options include:stock options, commodity options, bond options and other interest rate options, stock market index options or, simply, index options, callable bull/bear contract and options on futures contracts.
Over-the-counter options
(OTC options, also called "dealer options") 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. In general, at least one of the counterparties to an OTC option is a well-capitalized institution. Option types commonly traded over the counter include: interest rate options currency cross rate options, and options on swaps or swaptions.
Other option types
Another important class of options, particularly in the U.S., are employee stock options, which are awarded by a company to their employees as a form of incentive compensation. Other types of options exist in many financial contracts, for example real estate options are often used to assemble large parcels of land, and prepayment options are usually included in mortgage loans. However, many of the valuation and risk management principles apply across all financial options.
Naming conventions are used to help identify properties common to many different types of options. These include:
- European option – an option that may only be exercised on expiration.
- American option – an option that may be exercised on any trading day on or before expiry.
- Bermudan option – an option that may be exercised only on specified dates on or before expiration.
- Barrier option – any option with the general characteristic that the underlying security’s price must pass a certain level or "barrier" before it can be exercised.
- Exotic option – any of a broad category of options that may include complex financial structures.
- Vanilla option – any option that is not exotic.
