An option is a derivative contract which provides for the holder of this contract a right to buy or sell a security at a later date on specified terms.
There are mainly two types of option contracts -- calls and puts. Call option gives its holder a right to purchase an underlying security at a specified price till its expiry.
A put option meanwhile gives its holder right to sell an underlying security at a specified level. Put options can be exercised at any time before the expiry.
